BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described.
This will be described with reference to the drawings.

(First Embodiment) Hereinafter, a first embodiment of the present invention will be described with reference to the drawings. 1 is a system configuration diagram for realizing this embodiment, FIG. 2 is a diagram showing an embodiment, FIG. 3 is a block diagram showing an example of a main configuration in the system of the present invention, and FIG. 4 is an operation in the system of the present invention. It is a flowchart of.

The present invention is a technique for utilizing a notebook personal computer to which an electronic camera is attached or connected. Specifically, the electronic camera and the display are used, and information transmission is performed using an image as a medium. The display is a transmitting side, the electronic camera is a receiving side, and a predetermined image to be displayed on the display is regarded as a code. The communication is performed by regarding the image as a transmission signal.

In order to realize this embodiment, a device as shown in FIG. 1 is used. That is, in FIG. 1, 101 and 106 are notebook personal computers, 104 is a desktop personal computer main body, and 105 is its CRT display.

The notebook personal computer 1
Reference numeral 01 denotes a main body and a lid, and the lid is equipped with 102 electronic cameras and 103 liquid crystal panels. However, the electronic camera is not limited to such a form,
The external connection configuration in which the electronic camera 107 as a single unit can be used by connecting it with a cable or the like like the notebook personal computer of No. 6 does not depart from the gist of the present invention.

The personal computer main body 104 is a main body of a general desktop personal computer, and the CRT display 105 is a color CRT connected to the personal computer main body 104. Of course, this is a liquid crystal panel display (L).
(CD display). The point is that any display that can display a gradation image may be used.

In the present invention, as shown in FIG.
When transmitting data from the desktop personal computer to the notebook personal computer 101, the CR of the desktop personal computer is used.
A code image coded as an image corresponding to the data content is displayed on the T display 105, read by the electronic camera 102 in the notebook personal computer 101, and an image (code image) obtained thereby is decoded and The process of returning to the data meaning is performed internally to receive the data.

For this purpose, as shown in FIG. 3, a desktop personal computer 104 has an encoding unit 100 for converting information (data) to be transmitted into a code image which is a code in a format expressed by an image, and this encoding unit. A display unit (display) 10 for displaying the encoded image encoded in 100
5, a notebook personal computer 101, an electronic camera 102 for capturing images, and
And a decoding unit 108 for decoding original data from a code image in the image captured by the electronic camera 102.
Reference numeral 4 denotes a configuration which enables one-way communication without having mutually compatible communication means.

In this example, reference numerals 104 and 105 designate a transmission-side configuration, and reference numerals 101, 102 and 103 designate a reception-side configuration. As in this example, a desktop personal computer to a notebook personal computer 1 are used.
In order to transmit data to the personal computer 101, a code image DT obtained by encoding the data content is displayed on a CRT display 105 of a desktop personal computer. , An image (coded image) obtained thereby is decoded (decoded), and a process of returning the data to original meaning is internally performed to restore the data, and this is obtained as received data. .

This will be specifically described with reference to the flowchart of FIG. Desktop personal computer 1
In step 04, information to be transferred is prepared (step S
1a), by giving a transmission command, the prepared information is encoded by a predetermined technique (step S1d). In this encoding process, for example, the data content is converted into a bit string by binarized representation, the data string is divided by a predetermined number of bits, and the data is converted in a form corresponding to the predetermined color information corresponding to the divided bit string pattern. The color information is expressed in shades that can be expressed using three primary colors of R (red), G (green), and B (blue). Since various colors can be expressed by the mixing ratio of RGB,
Since codes of the same number as the number of colors that can be expressed can be assigned, color expression coding that can perform multi-bit expression of several bits for each hue is achieved.

The color-represented encoded data is displayed on a display as a color-represented code image. Each color is displayed as a two-dimensionally arranged image in a tile format. Here, the tile format is a form in which a rectangular area having an n × n pixel configuration is filled with the same color, and as a whole, a mosaic image in which m × m tiles are arranged vertically and horizontally. Then, the information corresponding to the color is included for each tile.

A plurality of bits of the data are converted into tiles of colors corresponding to the bit strings to form a code image (step S1c), and displayed on the display 105 of the desktop personal computer as a code image DT (step S1d).

In the notebook personal computer device 101, the electronic camera 102 captures the displayed code image (step S1e). In the notebook personal computer device 101, the captured code image is recognized by an image recognition technology, and the recognized image data is decoded, whereby the information of each color tile is decoded into the original bit string information. Is restored to digital data (steps S1f, S1f).

The above-mentioned encoding / decoding process may use a well-known one, but it is preferable to use the following encoding method in consideration of the advantage that a color image can be used.

<Example of Color Tile Coding Method> An embodiment of the above-described coding method using a color image will be described.
In the present invention, since the bit string of the desired data is replaced with color information and transmitted, in order to ensure reproducibility, the color (R) to be assigned to the code is first considered in consideration of the characteristics of the device to be used and the usage environment. , G, B) must be determined.

FIG. 5 is an assignment diagram in the case where each primary color, for example, two gradations is determined. In this case, since each of R, G, and B has two gradations (the luminance value takes either “0” or “255”), R = 0, G = 0, B = 0, and R = 0.
= 255, G = 255, B = 255 in total 8
It will be possible to generate the exact colors.

That is, the hue is R = 0, G = 0, B =
0, it becomes “black”, and R = 0, G = 0, B =
255 becomes “blue” and R = 0, G = 25
5 and B = 0, it becomes “green”, and R = 0, G =
The combination of 255, B = 255 becomes “light blue” and R
= 255, G = 0, B = 0, "Red", R = 255, G = 0, B = 255, "Murasaki", R = 255, G = 255, B = 0
Becomes “yellow” and R = 255, G = 25
The combination of 5, B = 255 becomes "white", and a total of eight colors can be expressed.

Then, "black" by the combination of R = 0, G = 0, B = 0 is made to correspond to the data string "000".
“Blue” in the combination of = 0, G = 0, B = 255 is associated with the data string “001”, and R = 0, G = 255,
“Green” by the combination of B = 0 is the data string “010”
And “light blue” by the combination of R = 0, G = 255, B = 255 is made to correspond to the data string “011”,
"Red" due to the combination of R = 255, G = 0, B = 0
Corresponds to the data string "100", and R = 255, G =
“Murasaki” by the combination of 0, B = 255 is made to correspond to the data string “101”, and R = 255, G = 255,
“Yellow” due to the combination of B = 0 is the data string “110”
In the combination of R = 255, G = 255, and B = 255, “white” corresponds to the data string “111”. Is encoded by applying the color of

If the visibility is good and the environment is good, the number of gradations can be further increased. For example, if each gradation is set to 4 gradations, 64 colors, which are 4 to the third power, are prepared for one image. You can do it.

In this manner, a bit string of information of a specific arrangement at the time of transfer is allocated to each color that can be generated determined by the characteristics and environment of the device, and the data of the corresponding arrangement is represented by a rectangle painted with a color corresponding to the arrangement. The image is expressed as one unit. That is, they are represented as color tiles.

The color tiles are mosaic in a two-dimensional array having a plurality of n × m arrays, as shown in FIG.
In FIG. 6, a1, a2, a3,... Are color tiles, respectively, and are represented by colors corresponding to data contents to be transmitted. As shown in FIG. 6, a code image is generated by arranging the squares two-dimensionally and expressing them as a large square. The setting relating to the display amount, such as the arrangement method and the density, can be arbitrarily determined in consideration of the resolution on the display side and the resolution of the electronic camera.

When the amount of data to be transmitted is large, such a code image is sequentially switched and changed in a time series as shown in FIG. 8 to be displayed as a moving image. Then, on the receiving side, the moving image displayed by the electronic camera 103 is captured and analyzed to receive the data. For the quality of the moving image, the number of frames per second may be determined according to the processing performance of the component devices.

Since this data transfer method is performed in one direction, there is a possibility that a problem such as the processing on the receiving side not catching up may occur, but there is no means for notifying the transmitting side of the problem.

Therefore, when all of the displayed code images cannot be completely received, there is provided a function for notifying the receiving user that there is a code image that has failed to be received and prompting the user to transfer the code image again. It is good to have it in the decoding section 108 on the receiving side.

Specifically, as shown at 113 in FIG. 7, a tag is attached by using a part of the code image in order to notify the number of the code image currently displayed.

That is, reference numeral 113 in FIG. 7 denotes a color frame in which the outer edge of the code image is bordered, and the color frame has information as a tag. The tag color is determined according to the number of the code image, and the encoding unit 100 is configured to create a code image in which the tag colors are associated in the transmission order of the code images. Make sure that the receiving side can confirm the order.

Therefore, in this case, the receiving side checks the color of the tag at the time of receiving the code image, so that if the color is out of the predetermined color order, it is possible to confirm that the transfer has failed. . Therefore, the decoding unit 108
Has a function to check the color of the tag when receiving the code image, and checks whether or not the color order deviates from the predetermined color order. If the color order of the tag deviates from the predetermined order, it recognizes that the transfer has failed. By providing a function of generating a notification output to notify the user, a system capable of notifying a transfer failure can be realized.

However, such a method is suitable if priority is given to the transfer efficiency, but if priority is given to certainty, it is sufficient to notify the success of the transfer by a predetermined key operation of the personal computer on the transmitting side. In other words, the user transmits the still image in units of still images while confirming the success of the transfer. The user transfers the data in a setting that considers the compromise between data volume and certainty.

As described above, in the first embodiment, the encoding means for converting the data to be transmitted in accordance with a predetermined rule to obtain a code (coded image) represented by an image, and the encoding means for obtaining the code represented by the image. Display means for displaying a code (code image) represented by the displayed image as an image, imaging means for reading a code (code image) represented by the image displayed on the display means as an image, and Code (code image) represented by the read image
And decoding means for decoding the data to obtain the original data.

Then, the stream of data to be transmitted is divided by a bit string having a predetermined number of bits, and an encoding process for converting the data stream into an image corresponding to the bit string pattern is performed for each of the divisions, displayed on a display screen, and received. On the side, the image is taken by the imaging means (electronic camera) and the image is taken in.
This image was decoded and returned to the original data.

The present invention is an application form of a notebook personal computer to which an electronic camera is connected, specifically, information transmission using an electronic camera and a display with an image as a medium. ,
This is a mechanism in which a predetermined image displayed on the receiving side of the electronic camera and the display is regarded as a code, and communication is performed by regarding the image of the code as a transmission signal. Although it is inferior to conventional communication means in terms of performance, this method is not a mass data transmission method, but the fun that can be used as a casual communication means between users by using images as a medium, There is no need to connect devices for communication or add special devices at all, and data transmission is possible without having compatible common communication means as hardware.

In the above, the personal computer devices are arranged close to each other, one is set as the transmitting side, the other is set as the receiving side, the camera is provided in the receiving side device, and the transmission contents are encoded on the display of the transmitting personal computer. An example is shown in which a video is displayed and the receiving river captures and decodes the image so that data can be transferred without a communication means. However, according to the present invention, if a code image can be transmitted on the transmission side, the code image is displayed on the screen of the television receiver through broadcasting, and the viewer can use a personal computer with a camera or an electronic camera alone to display the screen. By capturing the above code image and taking it into a personal computer used by the user, data transfer from a remote place can be performed without communication means. An example thereof will be described next as a second embodiment.

However, the personal computer 204 does not need to be of a notebook type, and may be of a type other than the notebook type, such as a desktop type. Further, there is no problem whether the electronic camera 205 is of a built-in type or an external connection type. As another form of 202 and 203, there is also an information display device with monitor 209 which can be installed in a station or a convenience store.

By decoding this by its own computer, it becomes possible to obtain the information of the sender represented by the code image.

As described above, the second embodiment of the present invention is a one-to-many information transfer method, and the same effects as those of the first embodiment can be expected from the viewpoint of using existing equipment. . Furthermore, since the transmitting side is in the form of broadcasting, if the user has a notebook personal computer with an electronic camera, the same information can be instantly transmitted to the majority of users with a small amount of work. Can be. Further, the present embodiment is also assumed to be carried around the city and carried around, and the effect can be expected. Specifically, by installing an information terminal equipped with a display at a place where users can drop in, such as convenience stores and station yards, an unspecified number of users can easily access information at any software level regardless of the model. The effect that can be obtained is obtained.

In the above, the code image is displayed on the screen of the television receiver through the broadcast, and the viewer captures the code image on the screen by using a personal computer with a camera or a single electronic camera, and the personal computer used by the user. In this example, data transfer from a remote place can be performed without a communication unit by incorporating the data into the data.
