FIG. 2 is an example of a block diagram showing an internal configuration of the card game apparatus, and shows a state in which the card game apparatus is connected via HuB.

As described above, 16 sensor units are provided inside the card game apparatus. The 16 sensor units are connected by a cable, and the cable is connected to the dot code output control unit via the HuB unit. Further, the dot code output control unit is connected to the game central processing unit, and the game central processing unit includes a display,
A speaker is connected.

  3 and 4 are block diagrams showing the configuration of the sensor unit.

FIG. 3 shows a sensor unit provided with a sensor and a central processing unit (MPU).

A lens is provided on the upper part of the sensor, and an IR filter is attached to the upper surface of the lens. In addition, LEDs are provided on the left and right sides of the sensor. A central processing unit (MPU) and a frame buffer are provided below the sensor. The image captured by the sensor is subjected to image processing by a central processing unit (MPU) attached to the sensor. This IR filter is a filter having optical characteristics that transmits only infrared wavelengths (700 nm or more).

  In FIG. 4, only the sensor is provided in the sensor unit.

A lens is provided on the upper part of the sensor, and an IR filter is attached to the upper surface of the lens. In addition, LEDs are provided on the left and right sides of the sensor. The image read by the sensor is processed by a central processing unit (MPU).

FIG. 5 is another example of a block diagram showing the internal configuration of the card game apparatus, and shows a state of being connected by a LAN. Each of the 16 sensor units is connected to a dot code output control unit via a LAN cable. Further, the dot code output control unit is connected to a game central processing unit, and a display and a speaker are connected to the game central processing unit.

6 and 7 are diagrams illustrating the card arrangement panel on the upper surface of the card game apparatus. As a structure of the card arrangement panel, for example, ones as shown in FIGS.

6A and 6C are views of the card arrangement panel as viewed from above, and FIG. 6B is an enlarged longitudinal sectional view showing a cross-sectional structure of the card arrangement panel in FIG.

A sensor unit (infrared irradiating means) in the card game device emits infrared light, and when viewed from above, a card reading unit is configured by a plurality of predetermined portions of the card arrangement panel (stage surface) as shown in FIG. Yes. A game is played by placing a card as a medium on the card reading unit so that the surface on which the dot pattern is formed faces the card arrangement panel (stage surface).

As shown in (b), the card arrangement panel has a stacking structure in which a plurality of inks are applied to the upper surface of a transparent glass plate. White ink is applied to the upper surface of the glass plate. Further, CMYK non-carbon ink is applied on the white ink.

By applying the white ink on the upper surface of the glass plate, it is possible to avoid that the surface of the card arrangement panel becomes black and it is difficult to visually check the contents printed with the non-carbon ink.

(C) is the one in which the ink used for printing is changed in the card reading unit, its periphery, and other parts. That is, the card reading unit and its periphery are printed using only non-carbon CMY ink that does not contain carbon, and the non-carbon CMY ink and carbon K ink are used except for the periphery of the card reading unit. Print.

Here, among the general-purpose inks usually used for printing, the CMY ink is a non-carbon ink that usually does not contain a carbon component, and the K ink is a carbon ink that contains carbon. Since carbon has a characteristic of absorbing infrared rays, when such a carbon ink is used for printing other than the dot pattern, it becomes difficult to distinguish it from the dot pattern when the infrared ray is irradiated onto the printing surface. . In order to avoid this, it is preferable that the K ink is also a non-carbon ink. However, since the non-carbon K ink is expensive, an increase in printing cost becomes a problem in a game card that requires low cost. .

Therefore, in the present embodiment, on the card arrangement panel (stage surface), only the card reading portion is printed with non-carbon component CMY ink, and the other portions are non-carbon component CMY ink and carbon component K ink. I decided to print it. Therefore, the K component of the card reading unit expresses K in a pseudo manner using non-carbon CMY ink.

In this way, general-purpose ink (non-carbon component CMY ink and carbon component K ink)
The structure which can permeate | transmit infrared rays selectively only by a card | curd arrangement | positioning panel (stage surface) is realizable. Here, when the infrared component of external light enters inside, it becomes noise during reading of the dot pattern, but as described above, almost the entire surface of the stage is made opaque to infrared rays and only the reading area is made transparent to infrared rays. By doing so, this noise can be reduced.

Further, the portion printed using only the non-carbon component CMY ink has a lighter color tone than the portion printed using the non-carbon component CMY ink and the carbon component K ink. For this reason, in a card reading unit that needs to be irradiated with light, it is possible to avoid a situation in which light is not sufficiently applied because the color tone is dark.

In the present invention, not only a glass plate but also other transparent plates such as acrylic may be used.

In the present invention, it is also possible to make a structure in which a hole is formed in a portion of the card arrangement panel where the sensor is irradiated to form a reading hole, and the upper portion of the reading hole is covered with glass to prevent dust. In this case, when the player places the card, the reading hole is completely closed, so that the IR filter above the sensor becomes unnecessary.

FIG. 7 shows a glass plate provided with an IR filter. (A) is the figure which looked at the card | curd arrangement | positioning panel from the top, (b) and (c) are the longitudinal cross-sectional views which expand and show the cross-section of a card | curd arrangement | positioning panel.

As shown in FIG. 2B, the IR filter is laminated on the lower surface side of the glass plate. IR
By using the filter, the card placement panel is darkened, and it is possible to prevent a built-in device such as a sensor from being viewed by the player (player).

When the IR filter is mounted on the card arrangement panel (stage surface) in this way, the player cannot see the inside and can improve the appearance of the card arrangement panel, but it is difficult to see the card reading unit during the game. It becomes difficult to know where to place the card on the card placement panel. Therefore, as shown in (a), a card arrangement position mark is provided to indicate to the player where to place the card.

In the present invention, not only the glass plate but also other transparent plates such as acrylic may be used as the card arrangement panel. A color filter may be used instead of the IR filter. Since the color filter can be obtained at a lower cost than the IR filter, the cost for manufacturing can be reduced. When an IR filter is used, it is not necessary to provide an IR filter above the sensor as shown in FIGS.

FIG. 4C shows a case where an IR filter is attached to the lower part of the glass plate only in the card reading portion, and a black filter is attached to the other portions. By taking this form,
It is not necessary to provide an IR filter on the sensor unit side (imaging means side), and the cost can be reduced as compared with the case where the IR filter is laminated on the entire lower layer of the card arrangement panel.

FIG. 8 is a plan view showing a state in which a game is played on the card game apparatus according to the present invention.

As shown in FIG. 8, in this card game apparatus, a player (player) faces a card placement panel in a standing or sitting position, and a monitor is placed at the end of the card placement panel as viewed from the player. Thus, three pairs of such card arrangement panels and monitors are arranged in parallel in the facing direction to constitute one unit of a card game device for six people.

That is, the player plays against any one of the other five players or all of them, places the card possessed by the player on the card placement panel, and sets the code value or coordinate value of the dot pattern printed on the card. The game progresses as a parameter. An image, a moving image, or the like that enhances the progress, result, and effect is displayed on the monitor.

In the figure, six units constitute one unit of game device, but the number is not limited to six.

<Second embodiment Single sensor game machine>
FIG. 9 to FIG. 39 show a second embodiment of the card game apparatus according to the present invention.

FIG. 9 is a perspective view showing the appearance of the card game apparatus, and FIGS. 10A and 10B are longitudinal sectional views thereof.

In this card game apparatus, the entire lower surface of the card arrangement panel is imaged by one sensor unit (imaging means).

The space on the lower surface of the card placement panel (the space under the stage) is a card surface (on the stage surface) on the panel surface (on the stage surface) at a position avoiding imaging light from the panel surface (the lower surface of the stage) of the sensor unit (imaging means). An IRLED (irradiation light source) that irradiates the dot pattern on the medium surface) with irradiation light and a diffusion filter that diffuses the irradiation light to the panel lower surface (stage lower surface) are provided.

The diffusion filter is provided in a frame plate shape so as to protrude from the side wall portion constituting the apparatus housing to the lower surface space of the card placement panel. This diffusion filter is made of a transparent or translucent glass plate or synthetic resin plate, and has a satin finish on one surface. The irradiation light of the IRLED is diffused through this diffusion filter, so that the entire lower surface of the card arrangement panel can be irradiated with the irradiation light. And when the card | curd is mounted on the card | curd arrangement | positioning panel, this irradiation light is irradiated to this card | curd surface, and the reflected light is imaged with a sensor unit (imaging means).

10A shows a case where a substantially horizontal frame-shaped diffusion filter is used, and FIG. 10B shows a case where a frame-shaped diffusion filter inclined toward the space is used. The diffusion filter shown in FIG. 5A is easy to process and can be obtained at low cost. Further, the diffusion filter shown in (b) is provided in an oblique direction so as to avoid imaging light from the lower surface of the card arrangement panel to the sensor unit, and can efficiently irradiate IRLED irradiation light to the lower surface of the card arrangement panel. It is like that.

  FIG. 11 is a plan view of the card game device shown in FIG. 9 as viewed from above.

  FIG. 12 is a block diagram showing an internal configuration of the card game apparatus, in which a sensor unit and a central processing unit (MPU) are configured separately.

Only one sensor unit is provided inside the card game apparatus, and this sensor unit is connected to a central processing unit (MPU) having a frame buffer via a cable. The central processing unit (MPU) is connected to a game central processing unit, and a display and a speaker are connected to the game central processing unit.

The internal configuration is not limited to this. For example, as shown in FIG. 13, a central processing unit (MPU) having a frame buffer is connected to the sensor unit, and the central processing unit (MP
A configuration in which a cable is connected to the game central processing unit from U) may be used. Since the sensor unit is directly connected to the central processing unit (MPU) in this way, it is possible to process signals from the sensor at high speed.

14 and 15 are diagrams illustrating a card arrangement panel on the upper surface of the card game apparatus.

14A and 14B are drawings in which the upper surface of the glass plate is printed. FIG. 14A is a view of the card arrangement panel as viewed from the upper surface, and FIG. 14B is a longitudinal sectional view showing an enlarged sectional structure of the card arrangement panel. is there.

The card arrangement panel has a stacking structure in which non-carbon ink is applied to the upper surface of a transparent glass plate as shown in FIG. White ink is applied to the upper surface of the glass plate. Further, CMYK non-carbon ink is applied on the white ink.

By applying white ink on the upper surface of the glass plate, it is possible to avoid the surface of the card placement panel from becoming black and making it difficult to see the contents printed on the non-carbon paper.

In the present invention, not only a glass plate but also other transparent plates such as acrylic may be used.

FIG. 15 is a plan view and a cross-sectional view showing a structure in which an IR filter is laminated on a glass plate in a card arrangement panel.

As shown in FIG. 2B, the IR filter is mounted on the lower surface of the glass plate. By using the IR filter, the card placement panel provided in the lower layer of the glass plate makes it difficult for outside light to enter the space below the card placement panel (the space under the stage). It can be prevented from being viewed by (player).

In the card game device according to the present embodiment, as shown in FIGS. 9 to 13, since the entire surface of the card arrangement panel is imaged by a single sensor unit (imaging means), the player can arrange the card arrangement. Cards can be placed anywhere on the panel. Therefore, a card arrangement position mark as shown in FIG. 7 is not necessary.

In the present invention, not only the glass plate but also other transparent plates such as acrylic may be used for the card arrangement panel.

A color filter may be used instead of the IR filter. The color filter
Since it can be obtained at a lower price than the IR filter, the manufacturing cost can be reduced. When an IR filter is used, it is not necessary to provide an IR filter above the sensor as shown in FIGS.

Further, the card arrangement panel is not limited to the one shown in FIGS. 14 and 15, and other embodiments such as printing only a part on the panel and attaching an IR filter to the other part may be used. Of course.

  Next, the dot pattern used in the present invention will be described (FIGS. 16 to 23).

FIG. 16 is an explanatory diagram showing GRID1, which is an example of the dot pattern of the present invention. FIG.
FIG. 4 is an enlarged view showing an example of information dots of a dot pattern and bit display of data defined therein. FIGS. 18A and 18B are explanatory diagrams showing information dots arranged around key dots.

The information input / output method using a dot pattern according to the present invention includes generation of a dot pattern 1, recognition of the dot pattern 1, and means for outputting information and a program from the dot pattern 1. That is, the dot pattern 1 is captured as image data by the camera, the reference grid point dot 4 is extracted first, and then the key dot 2 is extracted because the dot is not originally placed at the position where the reference grid point dot 4 is located. Next, the information dot 3 is extracted and digitized to extract an information area to digitize the information, and information and a program are output from the dot pattern 1 based on the numerical information. For example, information such as voice or a program is output from the dot pattern 1 to an information output device, a personal computer, a PDA, a mobile phone, or the like.

The dot pattern 1 of the present invention is generated by arranging fine dots, that is, key dots, information dots, and reference grid point dots 4 in accordance with a predetermined rule in order to recognize information such as speech by a dot code generation algorithm. To do. As shown in FIG. 1, the block of the dot pattern 1 representing information has a 5 × 5 reference grid point dot 4 arranged on the basis of the key dot 2, and the center surrounded by the four reference grid point dots 4. Information dots 3 are arranged around the virtual grid point 5. Arbitrary numerical information is defined in this block. The illustrated example of FIG. 1 shows a state in which four blocks (inside the thick line frame) of the dot pattern 1 are arranged in parallel. Of course, the dot pattern 1 is not limited to four blocks.

One corresponding information and program can be output to one block, or one corresponding information and program can be output to a plurality of blocks.

When the dot pattern 1 is captured by the camera as the image data, the reference grid point dot 4 corrects distortion of the lens of the camera, imaging from an oblique direction, expansion / contraction of the paper surface, curvature of the medium surface, and distortion during printing. Can do. Specifically, a correction function (X _n , Y _n ) = f (X _n ′, Y _n ′) for converting the distorted four reference grid point dots 4 into the original square is obtained, and the same function is obtained. Then, the information dot 3 is corrected to obtain a correct information dot 3 vector.

If the reference grid dot 4 is arranged in the dot pattern 1, the image data obtained by capturing the dot pattern 1 with the camera corrects the distortion caused by the camera. Even when the image data of the dot pattern 1 is captured by the camera, it can be accurately recognized. Even if the camera is tilted and read with respect to the surface of the dot pattern 1, the dot pattern 1 can be accurately recognized.

  As shown in FIG. 16, the key dot 2 is a dot in which four reference lattice point dots 4 at the corners of the four corners of the block are shifted in a certain direction. The key dot 2 is a representative point of the dot pattern 1 for one block representing the information dot 3. For example, the reference grid point dots 4 at the corners of the four corners of the block of the dot pattern 1 are shifted upward by 0.1 mm. When the information dot 3 represents the X and Y coordinate values, the coordinate point is a position where the key dot 2 is 0.1 mm downward. However, this numerical value is not limited to this, and can be changed according to the size of the block of the dot pattern 1.

  The information dot 3 is a dot for recognizing various information. The information dot 3 is arranged around the key dot 2 as a representative point, and the center surrounded by the four reference grid point dots 4 is set as a virtual grid point 5 and expressed as a vector using this as a starting point. Arranged at the end point. For example, the information dot 3 is surrounded by the reference grid point dot 4 and, as shown in FIG. 17, a dot 0.1 mm away from the virtual grid point 5 has a direction and a length expressed by a vector. Then, it is rotated 45 degrees clockwise and arranged in 8 directions to represent 3 bits. Accordingly, 3 bits × 16 pieces = 48 bits can be expressed by one block of dot pattern 1.

In the illustrated example, 3 bits are expressed by arranging in 8 directions, but not limited to this.
Of course, it is possible to express 4 bits by arranging in 16 directions, and of course various changes can be made.

The diameter of the key dot 2, the information dot 3 or the reference grid point dot 4 is preferably about 0.05 mm in consideration of appearance, printing accuracy with respect to paper quality, camera resolution, and optimal digitization.

Further, in consideration of a necessary amount of information with respect to the imaging area and misidentification of the various dots 2, 3, and 4, it is desirable that the interval between the reference grid point dots 4 is about 0.5 mm vertically and horizontally. In consideration of misrecognition of the reference grid point dot 4 and the information dot 3, the shift of the key dot 2 is preferably about 20% of the grid interval.

The distance between the information dot 3 and the virtual grid point surrounded by the four reference grid point dots 4 is preferably about 15 to 30% of the distance between the adjacent virtual grid points 5. This is because if the distance between the information dot 3 and the virtual lattice point 5 is closer than this distance, the dots are easily recognized as a large lump and become unsightly as the dot pattern 1. On the contrary, if the distance between the information dot 3 and the virtual grid point 5 is longer than this distance, it is difficult to identify which of the adjacent virtual grid points 5 is the information dot 3 having the vector directivity. Because it becomes.

For example, the information dot 3, as shown in FIG. 18 (a), the lattice spacing of placing the _{I 16} around the key dot from the block from the center _{I 1} clockwise is 0.5 mm, 3 at 2mm × 2mm Bit × 16 = 48 bits are expressed.

In addition, it is possible to further provide sub-blocks having independent information contents in the block and not influenced by other information contents. FIG. 18B illustrates this.
Sub-blocks [I ₁ , I ₂ , I ₃ , I ₄ ], [I ₅ , I ₆ ,
_{I 7, I 8], [} I 9, I 10, I 11, I 12], [I 13, I 14, I 15, I 16] Each independent data (3 bits × 4 = 12 bits) information The dot 3 is expanded. By providing sub-blocks in this way, error checking can be easily performed on a sub-block basis.

It is desirable that the vector direction (rotation direction) of the information dots 3 is uniformly determined every 30 to 90 degrees.

FIG. 19 shows an example of the bit display of the information dot 3 and the data defined therein, and shows another form.

In addition, using two types of information dots 3 that are long and short from the virtual lattice point 5 surrounded by the reference lattice point dot 4 and eight vector directions, 4 bits can be expressed. At this time, the longer one is about 25-30% of the distance between adjacent virtual lattice points 5, and the shorter one is 15-2.
About 0% is desirable. However, it is desirable that the center interval between the long and short information dots 3 is longer than the diameter of these dots.

The information dot 3 surrounded by the four reference lattice point dots 4 is preferably one dot in consideration of appearance. However, if it is desired to ignore the appearance and increase the amount of information, one bit is assigned to each vector, and the information dot 3 is expressed by a plurality of dots, so that a large amount of information can be provided. For example, the vector of concentric eight directions, an information dot 3 surrounded by four points lattice dots 4 can represent information of 2 ^8, and 16 pieces of information dots of one block 2 ^128.

FIG. 20 is an example of information dot and bit display of data defined therein, (a) shows two dots, (b) shows four dots, and (c) shows five dots arranged. It is shown.

FIG. 21 shows a modification of the dot pattern, where (a) is a six-information dot arrangement type,
(B) is a schematic diagram of 9 information dot arrangement type, (c) is a 12 information dot arrangement type, and (d) is a 36 information dot arrangement type.

  The dot pattern 1 shown in FIGS. 16 and 18 shows an example in which 16 (4 × 4) information dots 3 are arranged in one block. However, the information dots 3 are not limited to 16 pieces arranged in one block, and can be variously changed. For example, according to the amount of information required or the resolution of the camera, six information dots 3 (2 × 3) are arranged in one block (a), and nine information dots 3 in one block (3 × 3). 3) There are arranged (b), 12 information dots 3 (3 × 4) arranged in one block (c), or 36 information dots 3 arranged in one block (d).

22 (a) and 22 (b) show the dot patterns described in FIGS.
In the dot pattern of a block composed of × 3 = 9 lattice areas, the direction of the block is changed by changing the arrangement direction of the information dots 3 from another lattice area (direction area) by a specific lattice area (direction area). Is defined.

That is, in FIG. 22A, information dots 3 are arranged in the vertical and horizontal directions from the center in the lower left lattice region 34a, the central lattice region 34b, and the lower left lattice region 34c, and in the other lattice regions, the information is obliquely directed from the center. Dot 3 is arranged. Thus, the lattice regions 34a, 34
b, 34c are arranged to form a triangular shape connecting the lattice regions, that is, the base 34a,
From the relationship of the vertex 34b to 34c, it can be recognized that the block is upward.

As described above, the direction of the block is defined by the arrangement relationship (here, a triangle) of the lattice areas 34a, 34b, and 34c in which the arrangement direction of the information dots 3 in the block is changed (information dots are arranged in the vertical and horizontal directions from the center). be able to. As a result, the information dots 3 can be arranged in all the lattice regions in the block, so that the information dots 3 are arranged in all the lattice regions without sacrificing the lattice region for defining the direction of the block. can do.

Note that FIG. 23B is obtained by connecting two blocks shown in FIG. 23A in the vertical and horizontal directions.

  When only one dot pattern is printed on the back side of the card, it is desirable that the distance between the lattices is about 15 mm and the dot size is about 15% of the distance between the dots. Therefore, 2 mm to 2.5 mm is desirable, but not limited thereto. The inter-dot distance in the captured image is desirably 14 pixels or more.

FIGS. 24 to 27 are diagrams for explaining the cards used in the present invention and the movement of the cards. 24 and 25 are diagrams showing cards used when a game is played with the card game apparatus of FIG.

  First, in FIG. 24, a plurality of codes are provided in one card.

The card surface (medium surface) of the card (medium) is divided into four areas, and dot patterns representing different code values are printed on each. In this manner, four types of different information can be provided in one card. Here, when the player (player) moves the card on the card reading panel (on the stage surface), the area imaged by the sensor unit (imaging means) also changes, and the player parameter changes. .

FIG. 24 (b) shows a case where the player moves the card using a card having a card surface divided into four areas, and the code read by the sensor unit and the card orientation change. . When the player first places a card, it is assumed that there is an area of code 1 above the sensor reading position, and the angle between the card placement panel vertical direction (y-axis) and the card is α. Then, when the player moves the card, the area of the code 4 is positioned above the sensor reading position, and the angle between the vertical direction of the card arrangement panel and the card is changed to α ′. At this time, the sensor unit reads the code 1 before moving the card, and the dot code output control unit outputs information corresponding to the dot pattern of the code 1.

After the card is moved, the sensor unit reads the code 4, and the dot code output control unit outputs information corresponding to the dot pattern of the code 4. The change in the code and the change in the angle before and after the movement become parameters, and the game can be changed. For example, even if the dot patterns are read in the order of code 1 → code 4, the battle results can be made different between the angle α and the angle β (not shown).

The card shown in FIG. 24C is obtained by defining xy coordinates in a dot code. As a result, the dot pattern image read into the sensor unit is recognized by the central processing unit (MPU) in the sensor unit for the dot code and its position, and the corresponding data is received from the display or speaker via the game central processing unit. Is output. That is, by moving the card, changes in the card position (xy coordinates) and the card orientation can be read.

When the player first places a card on the card arrangement panel, the coordinate value of the information dot read by the sensor unit at a predetermined reading position is (x, y), and the vertical direction of the card arrangement panel Assume that the angle with the card is α. Then, as the player moves the card, the coordinate value of the information dot at the reading position becomes (x ′, y ′), and the angle between the vertical direction of the card arrangement panel and the card changes to α ′. . in this case,
Changes in coordinate values and changes in angle before and after movement are parameters.

FIG. 27A is a diagram for explaining a method of obtaining the card angle shown in FIG. FIG. 2B shows an example of a dot pattern printed on the back side of the card.
In addition, the straight line connecting the grid dots is displayed for convenience in understanding the dot pattern.
Such a grid line is not printed on the actual dot pattern (see FIG. 25A).

As shown in the figure, the angle between the shooting direction, that is, the y direction of the frame buffer and the direction of the dot pattern is α, and this is the card angle. The coordinates of the reference grid point dot P ₁ are (x ₁ , y ₁ ), the coordinates of P ₂ are (x ₂ , y ₂ ), and the distance between P ₁ P ₂ , that is, the distance between the reference grid point dots is Let l.

First, θ is determined by the x coordinate. Here, θ is 0 ≦ x ₁ −x ₂ ,
θ ₁ = | sin ⁻¹ {(x ₁ −x ₂ ) / l} | or θ ₂ = 180− | sin ⁻¹ {(x ₁ −x ₂ ) / l} |

And if 0> x ₁ -x ₂ ,
θ ₁ = 180 + | sin ⁻¹ {(x ₂ −x ₁ ) / l} | or θ ₂ = 360− | sin ⁻¹ {(x ₂ −x ₁ ) / l} |

Next, θ is determined by the y coordinate. Where θ is 0 ≦ y ₁ −y ₂
θ ₁ = | cos ⁻¹ {(y ₁ −y ₂ ) / l} | or θ ₂ = 360− | cos ⁻¹ {(y ₁ −y ₂ ) / l} |.

If 0> y ₁ -y ₂ ,
θ ₁ = 180− | cos ⁻¹ {(y ₂ −y ₁ ) / l} | or θ ₂ = 180 + | cos ⁻¹ {(y ₂ −y ₁ ) / l} |

Here, there are two solutions (θ ₁ , θ ₂ ) for θ based on the x coordinate and the y coordinate, respectively, and θ which is the same as the solution determined by the x coordinate and the y coordinate is selected and is defined as α.

Next, FIG. 25 shows a relationship among a dot pattern printed on the card surface, a code value, and an xy coordinate value.

FIG. 25A shows a dot pattern printed on the card surface. This dot pattern includes a code value and an xy coordinate value.

FIG. 25B is a table showing values defined in 32 bits from C _{0 to} C ₃₁ of the dot pattern. _C 0 -C ₇ is y coordinate as shown in _FIG, C 8 _{-C 15} is the x-coordinate,
C _{16 to} C ₂₇ mean code values, C _{28 to} C ₃₀ mean parity, and C ₃₁ means management code.

These values are arranged in the lattice region shown in FIG. 25C, and are specifically expressed as dots shown in FIG.

The coordinate value may be a single xy coordinate system for the entire card surface as shown in FIG. 26A, or four xy coordinates for each area partitioned for each code as shown in FIG. It may be a system.

FIG. 28 is a plan view of the state in which the card is placed on the card arrangement panel as seen from above.

The player can place the four cards A to D on any position on the card arrangement panel.

FIG. 29 is a diagram showing a captured image of a card placed on the card placement panel with a sensor unit placed on the lower side of the card placement panel.

As described above, the sensor unit is provided in the lower part of the card game apparatus housing and photographs the back surface of the card arrangement panel. Therefore, the image captured by the sensor unit is as shown in FIG.
The dot code printed on the back of the card is photographed.

FIG. 30 shows a pixel matrix for determining the presence or absence of a card. In this pixel matrix, one cell is composed of 16 pixels × 16 pixels, and predetermined pixels (hatched pixels in the figure) function as check pixels.

That is, the brightness of the check pixel group set at predetermined intervals (here, every 5 pixels) is detected, and the medium is placed on the pixel matrix when the brightness is equal to or greater than a preset threshold value. It is judged that it is being done.

  This will be specifically described below.

First, a central processing unit (MPU) or a game central processing unit provided in the sensor unit divides a shooting area into 18 × 22 vertical cells as shown in FIG. This cell is further divided into 16 × 16 pixels. Then, the brightness level (brightness) of the portion hatched in FIG. 30 among the pixels is measured. The bright level is expressed in 256 levels from 0 to 255. An arbitrary threshold is set, and if the brightness level is equal to or higher than the threshold, it is determined that a card, an object, or a hand is placed at that position. However, when the brightness level is 255, it is white noise, and it is not determined that a card or the like is placed.

  FIG. 31 is a diagram for explaining a method of analyzing a card code.

First, as described above, the photographing area is divided into 18 × 22 cells. Then, the cell is scanned in the right direction from the upper left cell by the sensor unit. Here, since the portions other than the dots of the card reflect infrared rays, they are photographed brighter than the area where the card is not placed. Therefore, scanning with the sensor unit is performed to search for a brightly photographed cell. If the cell is brightly photographed, it is determined that the card is placed there.
Then, the presence or absence of dots is determined by the method described above. The dot code printed on the card surface is read by sequentially searching for a bright area and determining the presence or absence of dots.

According to this method, since it is determined that there is a card in a bright area and dots are detected only in that area, the time required to detect the dots can be shortened.

Here, in this embodiment, since the dot is detected only in the portion of the cell (16 × 16 pixels) where the card is placed, the calculation by the central processing unit (MPU) or the game central processing unit can be made more efficient. The dot pattern reading time can be increased.

FIG. 32 illustrates a method for recognizing the position and angle of a card placed on a card placement panel (on a stage surface) when a game is played using the card game device and the card according to the present invention. FIG.

First, when the sensor unit images the dot pattern on the card surface by the method described above, the central processing unit (MPU) detects a code value corresponding to the dot pattern. When the central processing unit (MPU) detects the code value, it next searches for a key dot. Then, the x and y coordinates of the card center are calculated and set as the card position. The card position is
It is represented by x and y coordinates with reference to the lower right (upper left when imaged) of the arrangement panel. That is, by detecting the position of the card, the center of the card is calculated, and the x and y coordinates of the card center are obtained. Thereby, the position of the card is calculated. That is, in FIG. 32, the coordinates of the card A are (x _a , y _a ), the coordinates of the card B are (x _b , y _b ), the coordinates of the card C are (x _c , y _c ), and the coordinates of the card D are (X _d , y _d ).

The angle between the straight line connecting the card center and the key dot and the vertical direction of the card placement panel is α, and this is the card orientation. The card angle is calculated by the method described above.

  FIG. 33 is a diagram for explaining a method of calculating the angle and amount of movement when the user moves the card on the card arrangement panel (on the stage surface).

As to how to recognize that the card has moved, for example, when the pixel matrix on which the card is placed is detected by the sensor unit and the central processing unit (MPU) as shown in FIG. A code value is read from the pattern and a key dot is searched for. Thereby, the direction of the card on the card arrangement panel can be known. When the user moves the card on the card arrangement panel, the same code value moves on the card arrangement panel. Therefore, if the position where this code value is reproduced every predetermined time is connected as a trajectory, it is possible to recognize that the card has been moved, its moving direction, moving trajectory, and the like.

In addition, the central processing unit (MPU) has a difference in the direction of key dots before and after movement.
You can see the rotation angle by movement. Moreover, the movement amount and the movement time can be calculated.

In this way, the power of the cardholder may be made variable depending on the position of the card, or the game may be advanced with the amount of movement and the time of movement as parameters.

  Hereinafter, FIG. 33 will be specifically described.

As shown in the figure, it is assumed that the player moves the cards A, B, C, and D, respectively.
At this time, the center of the card A is changed from (x _a , y _a ) to (x _a ′, y _a ′), and the center of the card B is changed from (x _b , y _b ) to (x _b ′, y _b ′). , moving each center of the card C in _(x c, _{y c)} from _{(x c ', y c'} ), the center of the card D _{(x d, y} d) from the _{(x d ', y d'} ) Suppose that At that time, the angles with respect to the card arrangement panel are as follows: card A from α _a to α ′ _a , card B from α _b to α ′ _b , card C from α _c to α ′ _c , and card D from α _d. the alpha _'d, and were each changed. At this time, the amount of movement _{l a} of the card A,
l _a = √ {(x _a ′ −x _a ) ² + (y _a ′ −y _a ) ² }
It becomes.

In addition, the rotation angle θ _a is,
θ _a = α ′ _a −α _a
It becomes.

In addition, the time the _{T a} before the movement of the card, 'If you, the time _{t a} required for movement t _a = _{T a'} time after the move _{T a} -T _a
It becomes.

  The same applies to cards B, C, and D.

In this card game apparatus, when the player moves the card, a game in which the card movement amount, the rotation angle, and the movement time become parameters and the card power changes can be considered. That is, by moving the card, the strength of the card changes.

FIGS. 34A and 34B are diagrams illustrating the case where the trajectory of the card is used as a parameter. FIG. 34A shows a case where the card is moved in a circle, and FIG. 34B shows a case where the card is moved so as to draw a square. .

In the present invention, the trajectory when the player moves the card can also be used as a parameter. For example, the shape of the trajectory can be used as a parameter. That is, parameters such as card attributes may be changed depending on whether the player moves the card in a curved line as shown in (a) or moves in a straight line as shown in (b).

As another embodiment, the character displayed on the display can be controlled in association with the card trajectory on the card arrangement panel. For example, when the fighter plane is displayed on the screen and the player moves the card, it is possible to produce an effect that the fighter plane moves according to the movement of the card.

Further, the position and orientation of a camera (not shown) on the card arrangement panel may be moved in association with the trajectory.

In the above case, if the card is stationary for a certain time or more, it can be considered that the trajectory has ended. Further, it can be assumed that the trajectory is finished when the player releases the card from the card placement panel.

FIG. 35 is a plan view showing a state in which a game is played on the card game apparatus according to the present invention.

As shown in FIG. 8, in this card game apparatus, a player (player) faces a card placement panel in a standing or sitting position, and a monitor is placed at the end of the card placement panel as viewed from the player. Thus, three pairs of such card arrangement panels and monitors are arranged in parallel in the facing direction to constitute one unit of a card game device for six people.

That is, the player plays against any one of the other five players or all of them, places the card possessed by the player on the card placement panel, and sets the code value or coordinate value of the dot pattern printed on the card. The game progresses as a parameter. An image, a moving image, or the like that enhances the progress, result, and effect is displayed on the monitor.

In the figure, six units constitute one unit of game device, but the number is not limited to six.

FIG. 36 to FIG. 39 illustrate a card game device in which an image is displayed on the card arrangement panel in the card game device according to the second embodiment.

In this embodiment, the sensor unit (imaging means) is projected onto the stage surface by the code value or coordinate value of the dot pattern obtained from the image captured by the sensor unit in the space below the card arrangement panel (space below the stage). It is characterized in that a projector is provided as a projection means for controlling an image or a moving image.

In this embodiment, for example, when a card on which a dot pattern is printed is placed on the card arrangement panel, the infrared irradiation light emitted from the IRLED is irradiated to the entire lower surface of the card arrangement panel via the diffusion filter.

The infrared irradiation light reflected on the back side of the card is imaged by the sensor unit. At this time, an image or a moving image is projected from the projector onto the lower surface of the card arrangement panel.

When the sensor unit and the central processing unit (MPU) read the dot pattern printed on the card, the dot pattern is converted into a code value, and an image / moving image corresponding to the code value is projected from the projector.

In this way, images and moving images are projected from the lower surface of the card arrangement panel by the projector, and the projected images and moving images are controlled by the card on which the dot pattern placed on the card arrangement panel is printed. become.

  FIG. 37 is a longitudinal sectional view of the card game device according to the present embodiment.

As shown in the figure, the card arrangement panel is composed of a transparent plate made of glass or acrylic, and a screen sheet for a rear projector is laminated on the lower layer. In the space below the card placement panel (the space below the stage surface), a projector that projects an image or a moving image on a screen sheet, an IRLED that irradiates infrared light to the lower surface of the card placement panel, a diffusion filter that diffuses the infrared light, A CCD (sensor unit) as an imaging means is provided. In addition, an IR filter is attached to the tip of the CCD.

The CCD is connected to a central processing unit (MPU) not shown in the figure, and the captured image of the CCD is analyzed by the central processing unit (MPU), and the dot pattern printed on the back of the card is converted into code values and coordinate values. It has come to be.

In FIG. 38 (a), a mirror is provided obliquely in the space below the card arrangement panel (the space below the stage), and a projector (projection means) is disposed on one side of the mirror, and the projector (
The projected image or moving image from the projection means) is reflected on this one surface and projected onto the lower surface of the stage, and a CCD as an imaging means is arranged at a position avoiding the mirror in the space below the arrangement panel. Then, the imaging light of the dot pattern on the card surface (medium surface) on the card arrangement panel (on the stage surface) is incident on the imaging means while avoiding the mirror.

In FIG. 38B, a magic mirror is obliquely installed in the space below the card arrangement panel (the space below the stage), and a projector (projection means) is arranged on one side of the magic mirror. A projection image or a moving image from the projection means) is reflected on this one surface and projected onto the stage surface. Further, a CCD (imaging means) is disposed on the other side of the magic mirror, and the imaging light of the dot pattern on the medium surface on the stage surface passes through the magic mirror and enters the CCD (imaging means). It comes to be lit.

FIGS. 39A to 39C are diagrams for explaining images displayed on the card arrangement panel when the game is actually played. For example, first, an image of “Janken Game” is displayed on the card arrangement panel. Here, the player places a card printed with his / her predetermined dot pattern (here, the player ID) at the “start” display position (FIG. 39A).
. At this time, the IRLED below the card arrangement panel irradiates the card with infrared irradiation light via a diffusion filter.

A CCD (imaging means) that captures the reflected light from the card receives the captured image from a central processing unit (
MPU). The central processing unit (MPU) recognizes the dot pattern from the captured image and reads the code value (here, the player ID) corresponding to the dot pattern.

Next, the game central processing unit (MPU) that has received the code value from the central processing unit (MPU)
In FIG. 12 and FIG. 13, the projector is controlled to display the game start image on the card arrangement panel (FIG. 39B).

When the player (player) moves the card at the start of the game, the position of the card after the movement (coordinate value on the card arrangement panel) is recognized by the central processing unit (MPU) and the game central processing unit. Is done. Here, it is recognized by the central processing unit (MPU) and the game central processing unit that the card is placed at the position of “Jan”.

Next, the game central processing unit generates a random number, and based on the random number value, determines a hand (here, “choki”) on the game central processing unit side.

Next, the game central processing unit makes a game determination. This game determination is based on a determination table set in a memory (not shown). As a result of collation with this determination table, when a player's victory is determined (FIG. 39 (d)), points are added to the attribute of the player's ID.

<Other embodiments>
36 to 39 show examples in which images and moving images are projected directly from the projector onto the card arrangement panel. As shown in FIG. 40, the monitor (display) is provided separately from the card arrangement panel. May be.

Moreover, as shown in FIG. 41, the sensor unit may have a rail that can move in the xy direction.

Further, as shown in FIG. 42, the sensor unit is mounted as an image input unit so that it can be scanned (scanned) with a driving belt on a guide rail by a stepping motor, and is placed on an original platen made of glass. The dot pattern of the medium may be read.

FIG. 43 shows an application of the present invention as a home game machine, in which the dot pattern of the card can be read by the game machine main body, and the result can be displayed on an external TV monitor. It has become. Note that a memory card can be attached to the game machine main body, and the competition results, card parameters, images or moving image data may be stored in the memory card.

44 to 46 are modification examples of the game machine. The card may scan in the horizontal direction as shown in FIG.

In addition, as shown in FIG. 47, dot patterns may be printed on both sides of the card, the dot pattern on the lower surface may be read by the game machine body, and the dot pattern on the upper surface may be read by a pen-type scanner. Since FIG. 48 has the same configuration, description thereof is omitted.

49 and 50 illustrate a game machine in which cards are stacked and the dot pattern of a plurality of cards is read simultaneously by the sensor unit. Thus, the combination of the game parameters can be further complicated by reading a plurality of cards as a set.

The cards used for these are set in the game machine while being slightly shifted in the vertical direction, and even if a transparent card case capable of storing a plurality of cards in a shifted position is prepared as shown in FIG. Good. FIG. 51 shows the dot pattern forming surface of the card used at this time.

In addition to the card, the medium may be a figure having a dot pattern formed on the bottom surface thereof as shown in FIGS. 53 (a) and 53 (b). The stage is formed in a cylindrical shape, and the upper surface of the stage can be placed as a stage surface. A glass plate and an IR filter are laminated on the stage surface, and an IRLED, a diffusion filter, and a sensor unit are provided in the internal space.

In this way, even when a figure is used instead of a card, information to be output, such as speech, may be changed depending on the position and orientation of the figure on the stage surface, the distance between the figures, and the like. For example, the conversation content may be different between a conversation when the figures are facing each other and a conversation when the figures are facing each other. At this time, the direction and distance of the figure is the same as in the case of the card described in FIG.

<Embodiment in which infrared characteristics are changed>
54 to 68 selectively or superimpose any one or a plurality of dot patterns of two or more types of dot patterns formed of at least two types of inks having different reactivity printed on a medium. This is an embodiment in the case of reading automatically.

FIG. 54 shows an example in which a dot pattern is formed with two types of inks having different infrared absorption rates. Such a difference in infrared absorptance can be realized by controlling the carbon component contained in the ink.

  This figure shows an example in which two types of inks having different infrared absorption rates are used for the entire frequency range, that is, at any frequency, as at least two types of inks having different reactivities.

  In the present embodiment, the configuration of the information output device itself is the same as in the other embodiments.

In the figure, the ink a has an infrared absorptivity of 80% at the peak wavelength (850 nm).
The ink b has a characteristic that the infrared absorption rate is about 60% at the peak wavelength.

When a dot pattern is printed using these two types of inks a and b, as shown in FIG. 55, a dot of ink a having a high infrared absorption rate (80%) at the peak wavelength is recognized as black, and at the peak wavelength. A dot of ink b having a low infrared absorption rate (60%) is recognized as thin. In this way, a dot pattern in which only dots of the ink a are meaningful is formed by using the dots of the ink b as fooling dots. In general, since the dots of the ink b are copied without being distinguished from the dots of the ink a in the case of forgery, noise due to the ink b enters the copied dot pattern, and the dot pattern of the ink a Since reproducibility is not guaranteed, security can be increased.

FIG. 56 shows a case where three types of inks having different peak value wavelength characteristics of infrared absorptance are used.

Ink a has a peak wavelength of 850 nm, Ink b is 900 nm, Ink c is 950
Each has a peak wavelength of nm. A dot pattern is printed with these inks a, b, and c.

On the other hand, LED as infrared irradiation means LED-A having a wavelength characteristic of 850 nm,
A dot pattern is selectively or superimposedly irradiated using LED-B having a wavelength characteristic of 900 nm and LED-C having a wavelength characteristic of 950 nm. FIGS. 57A to 57C show the brightness of dots when each LED-A to C is selectively irradiated.

FIG. 58 shows the lightness and darkness of dots when printing is performed by superimposing the respective inks a, b, and c on lattice point dots (four corners). Thus, by printing the grid dots with all the inks, only the grid dots can be clearly identified regardless of which LED is irradiated. For this reason, once the grid dot is recognized, the position of the grid dot is stored in the memory, so that the reading efficiency is increased even when the light source is changed.

  FIG. 59A shows a first ink (ink a) having a low peak value of infrared absorption rate and a small wavelength at that time, and a second ink having a high peak value of infrared absorption rate and a large wavelength at that time. The case where (ink b) is used is shown.

In this embodiment, a light source (first irradiating means) in the entire infrared region and a first wavelength adapted to a wavelength (here, 850 nm) in which the infrared absorption rate of the first ink is higher than the infrared absorption rate of the second ink. Two irradiation means (LED-A) were prepared.

When the infrared whole area light source is turned on (FIG. 60 (a) and FIG. 61 (a)), LE
FIG. 60 and FIG. 61 show the degree of dot recognition when the DA is turned on (FIG. 60 (b) and FIG. 61 (b)).

As can be seen from these figures, when the infrared whole area light source is turned on, the ink b having a high infrared absorption rate is recognized as black, and when the LED-A is turned on, the ink a having a high infrared absorption rate at this wavelength (850 nm). Recognized black. In addition, inks a and b for grid dot
When superimposing and printing, grid point dots are recognized as black regardless of which light source is turned on.
In the present embodiment, as shown in FIG. 59 (b), the first ink is an ink having a high peak value of infrared absorptivity and a small wavelength at that time, and the second ink is an infrared absorber. An ink having a low peak value of the rate and a large wavelength at that time may be used.

62 to 64 show the case where ink a and ink b having different peak wavelength characteristics are used.
It is a figure explaining the control method at the time of using the single infrared irradiation light source with a variable wavelength characteristic.

As shown in FIGS. 63 and 64, the degree of recognition of ink a and ink b can be made different by changing the wavelength characteristics.

FIG. 65 to FIG. 67 show the infrared irradiation light sources LED-A and LED-B adapted to the inks a and b having different peak wavelength characteristics, and only the infrared irradiation light of the LED-B. It shows a change in the degree of dot recognition when a transmitting infrared filter is used.

In this way, by using the filter that selectively transmits the infrared wavelength of the ink b, by selectively arranging the filter as shown in FIGS. 66 and 67, the degree of dot recognition by the inks a and b can be increased. Can be different.

FIG. 68 shows an example of a dot pattern in the case of selectively adopting two types of dots using the difference in infrared wavelength characteristics due to the ink described above.

For example, when two types of dots having different infrared absorptances as described with reference to FIGS. 54 and 55 are recognized, dots printed with ink a that are recognized as black (dots filled with black in FIG. 68) and This shows a case where dots that are recognized lightly printed with ink b (dots hatched in FIG. 68) are selectively read out. In the figure, the dots surrounded by circles are selected. That is, a selection table is set on the memory of the information output device. For example, in the lattice block of FIG. 68, the dot of ink a is selected in the upper left lattice region,
In the upper middle, the ink b dot, the upper right the ink a dot, the middle left the ink b, the middle middle ink b, the middle right ink a, the lower left ink b, the lower middle ink a, the lower right ink. The dots are selectively read as b. In this way, extremely high security can be established by reading the dots based on the selection table so that correct information is output only.

In the above description, a dot pattern is printed on a card as a medium. However, in addition to the dot pattern, the card includes an RFID chip as shown in FIG. 69 and a magnetic stripe as shown in FIG. The magnetic recording unit may be a card in which an IC chip as shown in FIG.

By using a composite card provided with such storage means, it is possible to store the player's score and the like.

FIG. 72 is a view showing an example of a specific mole-tapping game apparatus using the present invention, and FIG. 73 is a sectional view of the stage surface.

In this embodiment, a dot pattern is printed on the hammer surface of the hammer held by the player (player). On the stage surface, the scenery of the meadow is printed on a transparent sheet with white paint, and several mole projections are provided. As shown in FIG. 73, in this mole projection unit, a diffusion filter is fitted in place of a transparent sheet layer coated with white paint and a non-carbon CMYK ink layer. A glass plate or a transparent plate such as acrylic is disposed on the diffusion filter and the non-carbon CMYK ink layer.

On the mole projection unit, a mole character is randomly projected from the lower surface of the stage by a projector every predetermined time, and when the mole character is projected, the hammer surface of the hammer is placed on the mole projection unit. When the dot pattern on the hammer surface is read by the sensor unit provided in the lower surface of the stage when positioned, the dot pattern is analyzed and converted into a code value set for each hammer surface, and the game central processing unit The score is added. Even if a mole surface is positioned on the mole projection unit when no mole character is projected on the mole projection unit, no score is added at that time. Further, when the mole character is not projected on the mole projection unit, the sensor unit may be programmed not to perform the dot pattern imaging process.

In addition, as described above, different code values for each hammer surface are printed as dot patterns, and for example, an advanced hammer (a dot pattern that means an advanced code value is printed on the hammer surface). When the game is used in a game, the game central processing unit that has read the dot pattern controls the projector to shorten the projection time of the mole character on the mole projection unit, thereby increasing the difficulty of the game. You may do it.

Although the dot pattern has been described as being formed on the hammer surface, it is needless to say that it may be a card printed with a dot pattern or a figure printed with a dot pattern on the bottom surface.

In the embodiment, examples of the medium include cards, figures, game hammers, and the like. However, the use of irradiation light with different ink characteristics or different characteristics increases dot pattern selectivity and increases security. The technology of the invention can be applied to forgery prevention target media such as tags, certificates (identification cards, passports), cash vouchers, and tickets. Of course, any of the RFID tag, the magnetic storage means, or the memory composed of the IC chip may be built in these forgery prevention target media.

<Still another embodiment>
(Corresponding to Claim 32)
74 (a) to 74 (d) illustrate cards as media. On the surface of these cards, the type of playing cards (a), English letters A (b), two-dimensional codes ( c) A dot pattern (d) is printed, but any image, character, figure, code, or pattern that is reproducible as code information taken by the imaging means and processed by the information processing means Also good.

  These pictures, characters, figures, codes, and patterns are printed with ink having infrared absorption characteristics.

  FIG. 75 is a perspective view showing the card game apparatus according to the present embodiment, and FIGS. 76 and 77 are partially perspective views thereof.

  The main body of the card game apparatus has a stage housing, and a projection panel as a stage surface is formed on the upper surface of the stage housing in a substantially horizontal direction.

  In addition, an infrared camera as a photographing means is arranged in the housing, and the lower surface of the projection panel is imaged through a mirror installed in an oblique direction. A projector is provided in parallel with the infrared camera, and multimedia information such as characters, figures, images, and moving images can be displayed on the lower surface of the projection panel via the mirror.

  Further, a display is erected on the opposite side of the projection panel from the side where the player is located, so that the player can play a card game while looking at the projection panel and the display at hand. .

  Although not shown in FIGS. 75 to 77, these infrared cameras, projectors, and displays are connected to and controlled by an information processing apparatus such as a personal computer.

  Although not shown in the figure, infrared irradiation means such as an IRLED for irradiating the lower surface of the stage is arranged in the casing in the same configuration as that shown in FIGS.

  In the information processing apparatus, based on the photographed image from the infrared camera, the position information of the card as the medium on the stage surface, the orientation information, or the medium state information such as the contact surface state between the projection panel surface and the card The code information printed on the medium surface, and the medium status information and the multimedia information such as characters, images, and moving pictures corresponding to the code information to the projector. Control is performed so that the output is displayed on all or part of the surface.

  In this way, the code information printed on the card is picked up by an infrared camera, and corresponding to the voice information etc., multimedia information such as characters, images and videos is displayed on the stage surface on which the medium is placed. The stage surface display effect linked to the code information of the card becomes possible.

  FIG. 78 shows a display example of cards and multimedia information on the projection panel. Here, a mark indicating a card standby area is displayed on the player side, and a card is arranged in this standby area as an initial state of the game. The upper surface of the tank is printed on the front surface of the card, and the code information of each tank is printed on the back surface as the dot pattern shown in FIGS.

  When the player moves the card from the standby area, the moving state is photographed by the infrared camera, and the movement of the card is recognized by the information processing apparatus. The arrangement and movement of the card at this time can be recognized by the technique described with reference to FIGS.

  By recognizing the arrangement and movement state of the card, the information processing apparatus reads out the image and moving image information associated with the arrangement position and operation state from the storage device (hard disk device not shown) or sequentially calculates them. And display on the projection panel via the projector. At this time, the image and video information are the bullets from the tank, the dust image when the tank travels in the desert, and the caterpillar trace image that remains in the desert, and project these images around the card in association with the movement of the card In this way, the presence of the card game can be increased.

  Examples of displaying other multimedia information are shown in FIGS. That is, on these projection panel surfaces, a command necessary for the game such as “attack point B” or cards and figures placed on the projection panel such as “HP +50” and “MP-20” are displayed. The game score and parameters (FIG. 85) that change depending on the situation, the speech of FIG. Such as “A's shadow is activated?” Are displayed in a balloon (FIG. 86), and further, a command for instructing the movement and destination of the card (FIG. 87). ) Etc. can be illustrated.

  In this way, by performing medium placement and operation instructions with the multimedia information displayed on the projection panel surface, it is possible to facilitate the operation of the medium and further enhance the effects of games and the like.

  Note that the information processing apparatus overlaps the contact surface of the card or the recording medium already placed on the projection panel surface with respect to the projector, the character, figure, image, or moving image information related to the card or the figure. It is desirable to output to a position that does not.

  For example, when a plurality of cards are placed on the projection panel surface, multimedia information such as characters, figures, images, and moving images can be displayed at positions avoiding the placed cards (FIG. 85). And FIG. 87). This can be realized when the information processing apparatus can recognize the position of the card on the projection panel surface described with reference to FIG.

  In addition, in the case of a figure (doll) having a height in which code information is printed on the bottom surface, characters, figures, images, images, Multimedia information such as moving images can be displayed (see FIG. 85).

  The dot pattern printed on the medium surface of the card or figure defines medium information indicating the type, shape or shape of the medium surface, and is projected onto the projection panel surface based on the medium information. Character, figure, image, or moving picture information may be generated.

  FIG. 95 shows an example of a dot code format when the medium type, medium material, medium surface shape information, and other information are included, and FIG. 96 shows an example of a medium defined by the dot code.

  By storing medium information indicating the type and shape of the medium in the code information, the information processing apparatus can identify the type and shape of the medium when picked up by the image pickup means. Media information can be output.

  For example, if information indicating the type of medium such as a figure or a card is used, a line consisting of characters is displayed on the projection panel surface in the case of a figure (see FIG. 86), and a score is displayed on the projection panel surface in the case of a card (see FIG. 85). Is possible.

  In addition, when the shape of the medium or the shape of the medium surface is stored as the medium information, the algorithm that the imaging unit directly recognizes the shape of the medium from the captured image can be omitted, and the character that takes the shape into consideration, Images and moving image information can be displayed on the panel surface.

  FIG. 78 shows an example in which the entire stage surface is used as a projection area and an infrared imaging area of the projection panel. As shown in FIG. 79, the projection panel includes the projection area (upper half of FIG. 79) and the infrared imaging area (lower part of the figure). You may divide into half.

  In other words, in the upper half of the projection area, still images and moving images from the projector are displayed, and infrared transmission printing is performed in the lower half, and still images and moving images are not displayed, but the back side of the card placed in this portion The dot pattern can be read by an infrared camera.

  In such a projection panel structure, a picture or a character may be printed with an infrared transmitting ink or an infrared transmitting sheet printed with the infrared transmitting ink may be attached to a part or all of the upper surface of the projection panel.

  As described above, the effect of combining with the multimedia information projected from below can be enhanced by printing the picture or the character on the upper surface of the projection panel in advance using the infrared transmitting ink.

  Further, by sticking an infrared transmitting sheet, the surface of the projection panel can be protected from damage and the like, and even if the infrared transmitting sheet is damaged, it can be easily replaced.

  FIG. 80 shows another application example. The projection panel is printed with an image inside the cockpit of the tank, as shown in FIG. 5A, and a part of the projection panel is not printed as shown in FIG. It is divided into a semi-projection area where transmissive printing can be performed and projected, and a non-projection area where infrared transmissive printing is performed and no projection is performed.

  In this way, by projecting a still image or a moving image by the projector onto the semi-projection area and the projection area, it is possible to produce a sense of realism that matches the progress of the card game.

  FIG. 81A illustrates a cross-sectional structure of each region in the projection panel. As shown in the figure, in the non-projection area, non-projection / infrared transmission printing is performed on the upper surface of the projection panel with ink that does not transmit projection light, infrared transmission graphic printing is performed on the upper layer, and the top layer is coated (or protected) A transparent sheet) is used to protect the surface. Further, in the semi-projection region, the uppermost layer is coated by performing infrared transmission printing on the upper surface of the projection panel. Further, in the projection area, only the coating is applied on the projection panel.

  In FIG. 81 (b), a graphic printing sheet is pasted on the projection panel, and the non-projection area is subjected to infrared transmission graphic printing and non-projection / infrared transmission printing on the upper layer of the adhesive layer on the projection panel surface. The printed sheet is arranged with the printing surface down. In the semi-projection area, a sheet subjected to infrared transmission graphic printing is disposed on the upper side of the adhesive layer on the projection panel surface side with the printing surface below.

  Further, the projection area is a sheet pasted through an adhesive layer. As described above, by arranging the sheet as the uppermost layer, the projection panel surface can be protected from damage or the like.

  83A to 83D are drawings in which a frame for designating a projection area to be projected by the projector or marks for designating the four corners of the projection area are printed on the upper surface of the projection panel or the infrared transmitting sheet.

  In this way, the frame or mark provided in advance on the upper surface of the projection panel or on the infrared transmitting sheet is used as a mark, and the mark indicating the frame and the four corners is projected from the projector onto the projection panel, and the projection area and the designated projection area are visually observed. The projected area of the image, ie, both marks are calibrated.

  Thereby, the displacement of the projector with respect to the projection panel can be easily calibrated.

  FIG. 84 is a diagram in which dot marks for designating the four corners of a region where an infrared image is captured are printed on the upper surface of the projection panel or an infrared transmission sheet with ink that absorbs infrared rays.

  The information processing means recognizes the coordinates of the four corners based on the dot marks imaged by an infrared camera, determines whether or not the four corner information of the imaging area stored in the storage means is in the same position, As a result, the information and the adjustment instruction information are displayed on the projection panel by the projection means. Specifically, as shown in the figure, “(1) Rotate the infrared camera 10 ° to the right. (2) Reduce the imaging area of the infrared camera by 5%. (3) Infrared Move the camera 2 cm to the right. (4) Move the infrared camera 1 cm down. ”Can be displayed. The numbers enclosed in parentheses () mean the numbers enclosed in a circle in the figure.

  82A to 82C show printing examples of the projection area designation frame and the imaging position calibration dot mark for calibrating the deviation of the projection panel with respect to the projector and the infrared camera. (C) is a calibration transparent sheet used when it is not desired to print the projection area designation frame and the imaging position calibration reference dot mark on the projection panel or the infrared transmission sheet, and can be removed after calibration.

  88 to 94 describe the operation and operation of the card and the figure on the projection panel and the technology for recognizing it.

  FIG. 88 shows the grid tapping operation of the medium on the projection panel surface, that is, the XY coordinate information calculated in an area substantially the same as or designated in the position where the medium is placed within a predetermined time and / or This is an example when the code information is read a plurality of times. Fig. 1 (1) is a card, and Fig. 1 (b) is the card's front surface (the surface opposite to the back side on which the dot pattern is printed). (C) is an example of a figure when a handle having an adhesive layer capable of being attached is attached.

  When a grid tapping operation using a card or a figure is performed on the projection panel surface, the infrared camera first reads a dot pattern printed on the back surface of the card or the bottom surface of the figure and recognizes the dot codes. After that, when the brightness of the reflected light from the infrared camera changes in the range of the same bottom shape as the bottom shape of the medium, the information processing apparatus determines that the grid tapping operation is performed on the projection panel surface, and Processing corresponding to the operation, for example, processing such as increasing the attack power parameter is performed.

  FIG. 89 similarly shows the grid twist operation.

  The grid twisting operation is an operation of rotating the medium around an arbitrary position of the medium surface on the projection panel surface. In this case, the information processing apparatus determines that the grid twisting operation has been performed by recognizing the rotation angle of the medium with respect to the direction of the imaging unit or the locus of the rotation angle as a repetition within a predetermined time. Then, processing corresponding to the operation, for example, processing such as increase of the defensive power parameter is performed.

  FIG. 90 shows the grid sliding operation.

  This grid sliding operation can be determined by sliding the medium on the projection panel in a circular shape so that the locus of the XY coordinate information calculated within a predetermined time is recognized as a substantially circular shape. When the information processing apparatus determines that the grid sliding operation has been performed, the information processing apparatus performs a process corresponding thereto, for example, a process of increasing a magic power parameter.

  FIG. 91 shows a grid scroll operation.

  This grid scroll operation is determined by recognizing the trajectory of the XY coordinate information calculated within a predetermined time as a substantially straight line by the linear scroll operation of the medium on the projection panel surface. When the information processing apparatus determines that the grid scroll operation has been performed, processing corresponding to the operation, for example, processing such as an attack by a character designated by the player is performed.

  FIG. 92 shows a grid scratch operation.

  The grid scratch operation is determined by recognizing the trajectory of the XY coordinate information calculated within a predetermined time as a recurrence of a straight line by the repetitive scratch operation of the medium on the projection panel surface. When the information processing apparatus determines that the grid scratch operation has been performed, a process corresponding to the operation, for example, a process such as cancellation of the player's command is performed.

  FIG. 93 shows a grid tilt operation.

  The grid tilt operation is determined by recognizing a change in the inclination of the medium with respect to the vertical line of the projection panel within a predetermined time by an operation of inclining the medium on the projection panel surface.

  Specifically, as shown in FIG. 93 (d), when the medium surface is inclined with respect to the projection panel surface, one (lifted side) of the image captured by the infrared camera becomes dark and the other (close to the panel surface). Side) becomes brighter. In this way, the information processing apparatus can determine that the grid tilt operation has been performed based on the brightness of the captured image.

  FIG. 94 shows a grid turnover operation.

  The grid turnover operation refers to an operation of turning a part of the medium surface on the projection panel surface. Specifically, the information processing apparatus can make the determination by recognizing a change in the area ratio of the medium surface separated from the projection panel surface within a predetermined time (see FIG. 94B).

  At this time, when the medium is a card such as a playing card, as shown in FIG. 94 (c), the image of the part turned from the projection panel surface (the type and number of the card printed at the corner of the playing card) remains as it is. The display effect on the projection panel surface accompanying the player's card operation can be enhanced by displaying in the area of the projection panel surface where the medium surface is separated.

  The information processing means detects operations such as grid tapping, grid twist, grid sliding, grid scroll, grid scratch, grid tilt, and grid turnover of the medium on the projection panel surface, and correlates with these operations. In addition, it is possible to change multimedia information such as characters, figures, images, and moving images to be displayed on the projection panel surface, thereby realizing various effects.

  In this way, by repeating operations such as grid tapping, grid twist, grid sliding, grid scroll, grid scratch, grid tilt, grid turnover, etc., characters, figures, images to be displayed on the projection panel surface depending on the number of times and speed It is also possible to further enhance the presentation effect for the player by changing multimedia information such as moving images.

  The operation history such as grid tapping, grid twist, grid sliding, grid scroll, grid scratch, grid tilt, grid turnover, etc. is stored in the memory means of the information processing means or the storage means such as the hard disk device, and these The multimedia effect such as characters, figures, images, and moving images displayed on the projection panel surface may be changed by a combination of actions to further enhance the effect on the player.

  The medium recognized on the stage surface may be the fingertip of the operator or the player himself, in addition to the card described above. Thus, when the fingertip is touched on the stage surface, the brightness of the stage surface of the touched portion changes, so that it can be recognized as the fingertip. Specifically, this will be described with reference to FIGS. 97 and 98.

  As shown in FIG. 97 (a), a game is played when a player or an operator places a card or touches the stage surface with a fingertip. (B) is the figure which showed the state which looked at this state from the stage surface under.

  (C) is a figure explaining the method of recognizing the shape of a medium. Brightness and darkness obtained by photographing infrared rays is stored in a storage area, and an area having brightness exceeding an arbitrary threshold is set as a contact surface with the stage surface. One contact surface is a region in which any one or more of vertical, horizontal, upper, and lower pixels that exceed the threshold among the pixels that constitute the storage region are continuous. .

  Specifically, an area surrounded by a thick line shown in (c) is an area of a pixel exceeding a threshold value, and indicates the shape of the medium.

  It is also possible to calculate the centroid of the medium from the image recognized in (c) and execute an operation corresponding to the coordinates of the centroid. Hereinafter, a method for calculating the centroid will be described.

First, the numerical value of the X coordinate of the pixel matrix exceeding the threshold is obtained. The value of X coordinates in each row _{are x} msns _{~x mene.} Then, the numerical values of all X coordinates are added. A value obtained by dividing the value obtained by the addition by the number of pixel matrices becomes the value of the X coordinate of the centroid.

  The Y coordinate of the centroid is also calculated by a similar method.
