Detailed ways

The characteristics of the present invention will be further clarified through the description of the embodiments shown below. However, the following embodiments are only one embodiment of the present invention, and the meanings of the terms of the present invention or each component are not limited to those described in the following embodiments. the

Hereinafter, the stereoscopic video display device and program of the present invention will be described based on FIGS. 1 to 13 . the

FIG. 1 shows an example of the configuration of a personal computer (stereoscopic video display device). CPU1 is connected with north bridge (north bridge) 2 having system control function, and south bridge (south bridge) 3 having interface function such as PCI bus or ISA bus. Connect storage 4 to Northbridge 2 or video card 5 through AGP (Accelerated Graphics Port). Furthermore, a USB (Universal Serial Bus) interface 6, a hard disk drive (HDD) 7, a CD-ROM device 8, and the like are connected to the south bridge 3. the

FIG. 2 shows a video card 5 in general. The VRAM (video memory) controller 5b controls writing and reading of drawing data to and from the VRAM 5a by commands from the CPU 1 through AGP. The DAC (D/A converter) 5c converts the digital video data from the VRAM controller 5b into an analog video signal, and supplies the video signal to the monitor 12 for a personal computer through the video buffer 5d. In this video display processing (rendering processing), right-eye video and left-eye video are generated, and stereoscopic video display processing such as rendering these alternately in vertical stripes or the like can be performed. the

The personal computer has a network connection environment, and can receive, for example, HTML files or XML files (for example, text files, e-mails, HTML files, XML files, etc.) from sending devices such as servers configured on the Internet. In addition, a personal computer can perform two types of display, a two-dimensional visual display and a stereoscopic visual display, by providing the monitor 12 with a liquid crystal barrier, for example. For example, if the right-eye video and the left-eye video are alternately arranged in vertical stripes for stereoscopic viewing, vertical stripe-shaped light-shielding regions are formed in the liquid crystal barrier under the control of the CPU 1 . In addition, if the stereoscopic visual video is displayed in a part of the area on the screen (the window part of the file reproduction, or a part of the video part in the HTML file), then the display coordinates and the size of the above-mentioned window or a part of the video part can be displayed by the CPU1, The size and formation position of the above-mentioned vertical stripe-shaped light-shielding regions are controlled. Not limited to the liquid crystal barriers, ordinary barriers (fence stripes fixedly formed at predetermined intervals) may be used. In addition, the personal computer is equipped with browsing software (browser) to open the file and display the video on the monitor 12 . the

Next, with reference to FIGS. 3 and 4 , the rendering process for stereoscopic viewing of documents performed by a personal computer (browser software) will be described. Among Fig. 3, the display example of " ABCDEFGHIJKL " this sentence is shown, and Fig. 3 (a) has shown the planar display example, and Fig. 3 (b) (c) has shown the three-dimensional display of the graphic character of " G " (see up like flying out) Example. As shown in Figure 3(b), as the video for the left eye, the graphic character part of "G" is shifted to the right by a predetermined pixel part (by this deviation, the "H" part is hidden (overlapped)), and the video for the right eye , the graphic character part of "G" is shifted to the left by a predetermined pixel part (the part of "F" is hidden (overlapped) by this deviation). Here, the amount of deviation of the graphic character portion of "G" is calculated from the description in the file, and the left-eye display data (ABCDEF GIJK) and right-eye display data (ABCDEG HIJK) in FIG. 3( b ) are generated. The description start position of "ABCDEFGHIJKL" is described in the file, and is specified by, for example, an X coordinate represented by <startx>/100</start x> and a Y coordinate represented by <start y>/100</start y>. Then, the pixel data constituting the left-eye display data (ABCDEF GIJK) and the pixel data constituting the right-eye display data (ABCDEG HIJK) are alternately started from the pixel data storage position of the VRAM corresponding to the above-mentioned coordinates (as a display image The right-eye pixel and the left-eye pixel are alternately written one by one in the horizontal direction). In addition, in Fig. 3(c), an example of transparently displaying the overlapping portion of "G" and "H" and the overlapping portion of "G" and "F" is shown. When compositing images so as to become translucent, the value obtained by adding the 1/2 values of the two image data may be processed as image data. the

In Fig. 4, a display example of the sentence "ABCDEFGHIJKL" is shown, Fig. 4(a) shows a plane display example, and Fig. 4(b) shows a stereoscopic display of the "EF" part (it looks like flying out )example. In this FIG. 4( b ), the hiding (overlapping) of adjacent characters is eliminated by shifting the plane view portion of "GHIJK". the

Fig. 5(a) shows an example of document description for displaying the sentence "ABCDEFGHIJKL" for two-dimensional viewing, and Fig. 5(b) shows an example of "EF" for stereoscopically displaying the sentence "ABCDEFGHIJKL". File description example (no overlap). The personal computer (browser software) judges the description portion indicating the processing for stereoscopic viewing among the descriptions in the file. In the example of FIG. 5 , the portion judged to be surrounded by <3d> and </3d> represents a processing portion for stereoscopic viewing. Then, the phase shift amount and shift direction of the target object (target character, target image) are judged based on the description part indicating the processing for stereoscopic viewing. In the illustrated example, "EF" is recognized as the target character. Furthermore, there is <zurasi L X>8</zurasi L X>, and according to this description, it is judged that the phase shift amount of the character for the left eye is 8 pixels on the right side. In addition, there is <zurasi L X>8</zurasi L X>, the deviation amount of the right-eye character can also be defined, it is omitted here (actually not recorded), and it is judged as the default value (0). Based on the phase shift amount and shift direction determined in this way, the image for the right eye and the image for the left eye of the target character "EF" are rendered. In addition, this example is an example of no overlap, and a personal computer (browser software) draws the position of the target object (character or image) adjacent to the object by a portion that is shifted by more than the phase shift amount to the side in the direction of deviation from the object. deal with. In the example of Fig. 5(b), according to <zurasi X> described after "GHIJK", </zurasi X> (this description is actually omitted. In this case, set the value of <zurasi L X>, That is, in 8), the characters of "GHIJK" are drawn to the right side only with a shift of 8 pixels. the

In this way, the personal computer (browser software) judges the object, the amount of phase shift, and the direction of the shift based on the meaning described above, and performs the processing of rendering the image for the right eye and the image for the left eye. the

In addition, the phase shift amount of the planar visual display part ("GHIJK") needs to be equal between the left-eye image and the right-eye image. The stereo vision part ("EF") changes the amount of deviation according to the amount of flying out (or the amount of entering). In addition, the amount of deviation between the stereoscopic visual display part and the planar visual display part may also be different. However, if (the phase shift amount of the 3D display portion)≦(the phase shift amount of the 2D partial display portion) does not hold, overlapping will occur. In addition, in order to more effectively stereoscopically display each object ("E" and "F"), the objects ("E" and "F" above) may be separated and phase shifts may be given to each. the

FIG. 6 shows another description example (whether or not overlap is indicated by a label). <shift>8</shift> indicates that the relative phase shift amount between the image for the left eye and the image for the right eye is +8. <overlap>has</overlap> defines that there is overlap. the

The amount of relative phase deviation between the image for the left eye and the image for the right eye

+ (positive: flying out): corresponds to the character for the right eye, deviates to the right from the character for the left eye (deviation by 8 pixels). the

- (minus: enter): corresponds to the character for the left eye, deviates to the right from the character for the right eye (deviation by 8 pixels). the

Whether there is overlap

Yes: Left and right are equally deviated from "EF" (4 pixels each). "GHIJK" without deviation. the

None: Offset "EF" to the right only (offset by 8 pixels). the

Rightward deviation "GHIJK" (8 pixel deviation) to the same value (absolute value) as the relative position deviation amount of the left and right characters. That is, the personal computer (browser software) judges the target character, the phase shift amount, and the shift direction according to the meaning described above, and performs right-eye image rendering and left-eye image rendering processing. the

FIG. 7 shows another description example (the amount of flying out is expressed horizontally). the

Stereo Directional Fly-Out: Right-eye character deviates to the right from the left-eye character. Entry: Deviates to the right from the left-eye character to the right-eye character. the

The phase offset level of the left and right characters defines the relationship between levels and pixels. The specific number of pixels corresponding to the definition is stored in the memory of the personal computer in advance as a setting table. Strong: 8 pixels off Medium: 4 pixels off Weak: 2 pixels off

With or without overlap: Left and right are equally deviated from "EF" (each deviated by 4 pixels). "GHIJK" does not deviate. None: Deviates to the right by "EF" only. (Offset by 8 pixels) To the right of the same value (absolute value) of the relative phase offset amount of the left and right characters by "GHIJK" (offset by 8 pixels). That is, the personal computer (browser software) judges the target character, the phase shift amount, and the shift direction according to the meaning described above, and performs right-eye image rendering and left-eye image rendering processing. the

FIG. 8 shows another description example (proportional representation of the ejection amount). <shift ratio>60</shiftratuo> indicates that the relative phase deviation rate between the left-eye image and the right-eye image is 60%. the

Stereo Directional Fly-Out: Right-eye character deviates to the right from the left-eye character. Entry: Deviates to the right from the left-eye character to the right-eye character. the

The maximum relative phase deviation of the left and right characters is set at 10. This information is stored in advance in the memory of the personal computer as a setting table. the

N%: Deviates by 10×N/100 pixels (if N=60, deviates by 6 pixels). Round off after the decimal point and take the whole number. The maximum value can be specified by the user, or it can be displayed information (the maximum value is different due to different displayed sizes). the

With or without overlap: Left and right are equally deviated from "EF" (each deviated by 3 pixels). "GHIJK" does not deviate. None: Deviates to the right by "EF" only. (Deviation by 6 pixels) The amount of relative phase deviation to the left and right characters and the same value (absolute value) deviate to the right by "GHIJK" (Deviation by 6 pixels). That is, the personal computer (browser software) judges the target character, the phase shift amount, and the shift direction according to the meaning described above, and performs right-eye image rendering and left-eye image rendering processing. the

FIG. 9 shows another description example (showing movement). the

Before and after movement: start with the standard phase deviation, move back and forth between the maximum phase deviation and the minimum phase deviation. Left and right: With the standard phase deviation, it starts to reciprocate left and right from the half position of move_h. From left to right: move from left to right, once it reaches the right, start moving from the left again (moving amount is move_h) From right to left: move from right to left, once it reaches the left, start moving from the right again (moving The amount is move_h) Rotation: start with the front (2D) state, and then follow the capture method described later Rotation still: stand still (not moving) with the standard phase deviation amount, others can also be from front to back, from back to front. the

The number of times of exercise means the specified number of times to exercise, return to the start state and stop. When 0 is specified, it repeats infinitely. the

With or without overlap: Left and right equal deviation from "EF". "GHIJK" does not deviate. None: Deviates to the right by "EF" only. In the absolute value of typ_shift, max_shift, min_shift, "GHIJK" of the maximum value part shifted to the right. In the case of moving left and right, move_h is also added. the

In addition, since tags to be used vary depending on the type of event, personal computers (browsers) are ignored when describing unnecessary tags. the

Supplement 1: Rotation method The easiest way to achieve rotation is to use the usual character rotation to take out characters at different angles. As shown in FIG. 10, since the rotated character can be seen as a graphic of the character "EF" from different angles, stereoscopic viewing can be performed by using two character graphics at subtly different angles as left and right images. At this time, in the character "EF", since there are protruding parts and entering parts, the amount of phase shift is changed by character parts (pixels). The state where the parallax becomes the strongest among these states is specified with max_shift, min_shift. The drawing positions of character parts can be determined by these values. the

Supplement 2: Stereo mode The above situation can be realized no matter whether it is stereo mode or not. When the number of viewpoints is greater than 2, for example, 4 viewpoints, the amount of phase shift between the characters of the first viewpoint and the characters of the second viewpoint and the characters of the third viewpoint and the characters of the fourth viewpoint is determined. Also, in multi-viewpoints, the processing when there is no overlap is substituted. In the case of 4 viewpoints, "GHIJK" is shifted by the offset portion between the characters of the first viewpoint and the characters of the fourth viewpoint (relative phase shift amount of the left and right characters×3). However, in this way, since the synthesis processing and the processing at the time of superimposition are changed depending on the stereo system or the number of viewpoints, it is only necessary to give such information in advance. The content for compositing processing can also be given with a function. the

That is, the personal computer (browser software) judges the target character, the amount of phase deviation, the direction of deviation, etc. according to the meaning described above, the information of the number of viewpoints or functions, etc., and performs the first viewpoint character, the second viewpoint character, the third viewpoint character and the third Drawing processing of 4-viewpoint characters. the

FIG. 11( a ) shows another description example (indicating the presence or absence of overlap and transparency with labels), and FIG. 11( b ) is an explanatory diagram showing drawing processing. the

Relative phase deviation amount of left and right characters+ (positive: fly out): the character for the right eye deviates to the right from the character for the left eye (deviation by 8 pixels). - (minus: enter): Deviates rightward from the character for the left eye (by 8 pixels) from the character for the right eye. the

Whether there is overlap (overlap): the left and right deviate from the graphic characters equally (each deviates by 4 pixels). "GHIJK" does not deviate. None: Offsets the glyphs to the right only (by 8 pixels). Deviate "GHIJK" to the right by the same value (absolute value) as the relative phase deviation of the left and right characters (8 pixels). the

Display priority (<priority>) 1: display the characters displayed in stereoscopically as the upper layer (hide the characters displayed in the superimposed plane) 2: display the characters displayed in stereoscopically as the lower layer 0: the browser (player) that depends on the display does not When setting this tag (default) is 0

According to the description of transparency (<transparency>M</transparency>), transparency of displayed characters (graphic characters) is set in M%. The default (when not set) is 0%. For example, if the R pixel data of the object specified transparently is R1, and the R pixel data of the overlapped object is R2, then the R pixel data can be drawn by (R2×M/100+R1×(1 - M/100)) to get. the

However, when the object is projected and viewed stereoscopically, the motion-sensitive character width F becomes smaller than the original character width D as shown in FIG. 12 . Therefore, in the two-dimensional visual display of the characters (designated size characters) described in the document, the browser executes the process of processing the "EF" character that becomes the stereoscopic visual object to, for example, double the character string as shown in Figure 13(a). Character size handling. After this processing, rendering processing (phase shift processing) of the image for the right eye and the image for the left eye is performed. In the non-overlapping setting, as shown in FIG. 13( b ), the phase of "GHIJK" also deviates. On the other hand, if it is set to overlap, drawing processing is performed as shown in FIG. 13( c ). the

As can be seen from FIG. 12, there is a relationship of D:(A+B)=F:B, C:A=E:B, and it becomes F/D=E/(E+C). Since the character becomes E/(E+C) (reduced) by flying out, the character is enlarged (E+C)/E times and displayed in advance. E is a constant around 65mm. For example, when a phase shift amount corresponding to a parallax amount C=65 mm is set, the characters are drawn by doubling the size of the characters in advance because the characters are reduced in size by 1/2. Here, the personal computer (browser) holds pixel pitch information of its own monitor 12 in advance. For example, there is a table that obtains the pixel pitch from the screen inch size and screen resolution, for example, the pixel pitch (mm) is obtained by asking the user to input the screen inch size and screen resolution. A personal computer (browser) obtains the value of (E+C)/E from C (mm) obtained by multiplying the above-mentioned pixel pitch by the phase shift amount (number of pixels) described in the document and E=65mm, Pixel interpolation (enlargement processing) corresponding to the original character is performed based on this value. Or determine the character size that satisfies the size obtained by multiplying the value of (E+C)/E by the original character size, obtain and draw the "EF" point data of the character size, and when drawing, make the enlarged The coordinates are determined so that the upper and lower positions of "EF" become the center of the line and drawn. For example, when the number of vertical pixels of the original character is 20 and the number of vertical pixels of the enlarged character is 40, through the calculation of (40-20)/2=10, corresponding to the reference position (downloading position), the " EF" characters are drawn downward only by a 10-pixel portion. the

In addition, in the above example, a personal computer that recognizes a file and displays an image is illustrated, but it is not limited to this, and it can also be used as a digital broadcast receiving device that can receive data broadcast (BML file) and display an image, or have a network connection environment. and a mobile phone with an image display function. the

Next, another example of rendering processing for stereoscopic viewing of a document by a personal computer (browser) will be described with reference to FIGS. 14 to 17 . In Fig. 14(a), a "Σ" character display example with a flat (2D) character attribute is shown, and in Fig. 14(b), a "Σ" with a three-dimensional (3D) character attribute is shown. Character display example. the

In the "∑" character display with stereoscopic (3D) character attributes, not only the left and right viewpoint images of the character are drawn, but also the shadow of the character (the shaded part shown in the figure is lighter than the character). In the case of displaying the character "Σ" flying out to the near side, as long as the image for the left eye deviates to the right by a predetermined amount of pixels from the original display position of the displayed character, the image for the right eye will be displaced from the original display position of the displayed character. Just deviate to the left by the specified amount of pixels. the

As the character attribute information, the amount of phase shift may describe the number of shifted pixels or the degree of shift. The degree of deviation can be determined by software, for example, the degree of deviation is only 1 or 2 pixels, and only 2 or 4 pixels. In addition, the amount of phase shift may be determined based on the character size as character attribute information. For example, there is a method of making the phase shift amount proportional to the character size. In this case, on the software side, the value of the proportional constant is held in advance, and the amount of phase shift can be determined by arithmetic processing of multiplying the proportional constant value by the character size. Alternatively, a configuration in which a table corresponding to character sizes and phase shift amounts is prepared in advance in software may be employed. the

In addition, regarding the deviation direction, it is also possible to have an observation method (fly out=0, enter=1, etc.) as a character attribute. In addition, in the drawing of the offset-processed characters (three-dimensional object characters) and shadows, starting from the storage position of the VRAM pixel data corresponding to the drawing coordinates, the pixel data constituting the left-eye display data and the pixel data constituting the right-eye display Alternate pixel data (a display image in which pixels for the left eye and pixels for the right eye are alternated by 1 pixel each in the horizontal direction) are written. the

The shadow of the three-dimensional object character may be drawn in black and gray with the same shape as the character deviated by a predetermined pixel amount toward the right position of the character, for example. Furthermore, when drawing a three-dimensional object character with a shadow, the three-dimensional object character and the shadow may be integrally shifted by the same phase, or the three-dimensional object character and the shadow may be shifted by a different amount of phase shift. For example, when shifting the left-eye characters to the right by 4 pixels relative to the original display position, the shadow can be shifted to the right by only 2 pixels; relative to the original display position, shifting the right-eye characters to the left At 4 pixels, the shadow is only offset to the left by 2 pixels. the

The phase shift amount in shading may be included as a character attribute, or the phase shift amount in shading may be half of the character phase shift amount, etc., depending on the character phase shift amount on the personal computer (browser) side Arithmetic processing is performed to generate the shadow offset amount. the

In addition, in the case of drawing a three-dimensional object character with a shadow, when the three-dimensional object character is displayed by flying out, as shown in FIG. , it is also possible to display only off-center characters. At this time, the shadow looks like it is on the same plane as the characters displayed on other planes, and the three-dimensional object character looks like it is flying out of the above plane. the

In addition, when a personal computer (browser) draws a three-dimensional object character with a shadow, as shown in FIG. and Phase Deviation Judgment), draw in such a way that the shadow position increases. In this process, when performing the process of shifting the three-dimensional object character and the shadow as a whole by the same amount, the separation between the three-dimensional object character and the shadow may be changed according to the amount of phase shift, or as described above, The phase shift amount in shadow drawing is half of the character phase shift amount, etc., and parallax is given to the shadow itself, so that the shadow position deviates greatly. the

The shadow color is not limited to the aforementioned black or gray, and it can also be drawn by changing saturation and/or brightness in the same color system (same or similar hue) as the color of the three-dimensional object character. For example, the shadow color is displayed darker or brighter than the color of the solid object character. When the image processing is performed by RGB, if the R value, G value, and B value are all lower than a predetermined amount, it becomes darker, and conversely, if it is uniformly higher than a predetermined amount, it becomes brighter. In addition, it is also possible to convert the R value, G value, and B value into HIS (hue: Hue, saturation: Saturation, brightness: Intensity), perform calculation processing to change the saturation, and then return the R value, G value, and B value and depict. It is also possible to have a shade color as a fixed color or a color of a subordinate character as an attribute character. The personal computer (browser) performs drawing color selection processing based on the above character attributes. the

However, when the characters are projected and viewed three-dimensionally, the motion-sensitive character width F becomes smaller than the original character width D as shown in FIG. 12 above. Therefore, instead of rendering as if the character size of the three-dimensional object character is displayed using the original character attribute, processing to double the character size, for example, is performed. After this processing, rendering processing (phase shift processing) of the image for the right eye and the image for the left eye is performed. the

As can be seen from FIG. 12, there is a relationship of D:(A+B)=F:B, C:A=E:B, and it becomes F/D=E/(E+C). Since the character becomes E/(E+C) (reduced) by flying out, the character is enlarged (E+C)/E times and displayed in advance. E is a constant around 65mm. For example, in the case of setting a phase shift amount corresponding to the parallax amount C=65mm, since the characters are reduced by 1/2 and feel uncomfortable, the characters are doubled in advance and drawn. Here, the personal computer (browser) holds pixel pitch information of its own monitor 12 in advance. A personal computer (browser) has a table for obtaining a pixel pitch from a screen size and a screen resolution, and, for example, allows a user to input a screen size and a screen resolution to obtain a pixel pitch (mm). the

The personal computer (browser) obtains the value of (E+C)/E based on C (mm) obtained by multiplying the above-mentioned pixel pitch by the phase deviation (number of pixels) in the character attribute and E=65mm. Pixel interpolation (enlargement processing) corresponding to the original character is performed on this value. Alternatively, it is judged that the character size satisfies the size obtained by multiplying the value of (E+C)/E by the original character size, and dot data of the character size is obtained and drawn. In this drawing, the coordinates are determined so that the upper and lower positions of the enlarged three-dimensional object characters become the center of the line, and the drawing is performed. For example, the number of vertical pixels of the original character is 20, when the number of vertical pixels of the enlarged character is 40, through the operation of (40-20)/2=10, corresponding to the reference position (filling down position), the three-dimensional The object character is drawn with only a 10-pixel portion shifted downward. the

In the above processing, the body-feeling width of the character that looks like flying out is made the same as the original character width, but the personal computer (browser) can also execute the larger the amount of flying out, the wider the width of the character as shown in FIG. The physical size of the characters is processed to be larger than the original size. In addition, it is also possible to perform a process of making the physical size of the character smaller than the original size (removing the constituting pixels of the character, etc.) as the amount of entry increases. the

In addition, in a personal computer (browser), as shown in FIG. 16(c), the larger the amount of flying out of the three-dimensional object characters, the brighter the display of the characters; the larger the amount of entry, the darker the display of the characters. When the image processing is performed by RGB, if the R value, G value, and B value are uniformly lower than a predetermined value, the color of the three-dimensional object character will be darkened; the

In addition, when the display character of the personal computer (browser) is a plane display character with a cancel line, as shown in FIG. 17(a), two horizontal lines are drawn superimposed on the display character "NY". On the other hand, when a three-dimensional object character is a character with a cancellation line, as shown in FIG. For example, when the character "NY" for the left eye is deviated from the original display position by 2 pixels to the right, the cancel line is deviated by 4 pixels to the right; when the character for the right eye is deviated from the original display position by 2 pixels to the left When "NY", the cancellation line is only offset to the left by 4 pixels. The amount of phase shift in canceling line drawing may be included as a character attribute, or the amount of phase shifting in canceling line drawing may be twice the amount of phase shifting in characters, etc. The (browser) side performs arithmetic processing to generate the deviation amount of the cancellation line. the

The personal computer (browser) draws the cancellation line of the three-dimensional object character with any one of hatched line, thick line, wavy line, and dotted line as shown in FIG. Compared with the case where only a line is drawn as a cancellation line, the drawing method described above tends to make the left and right viewpoint images of the cancellation line different from that of the cancellation line, thereby improving the three-dimensional effect of the cancellation line. the

FIG. 18 is an explanatory diagram showing a sentence of "I go to NY" and attribute information of characters constituting the sentence. Each character has an attribute of "3D display" (with/without) in addition to "font" and "size" which are normal character attributes. Furthermore, as "3D information", there are, for example, "fly out/in" (0/1), "deviation degree" (for example, specified by a value of 1 to 5), "shaded" (with/without), "lightly shaded Color designation" (yes/no), "shadow deviation change designation" (yes/no), "character brightness change designation" (yes/no), "character size change designation" (yes/no) and other attributes. The personal computer (browser) recognizes the character set as "Yes" in "3D display" as a three-dimensional display character, and judges the amount of phase deviation according to the various attribute information of "3D information", as described above, in accordance with the meaning described above and deviation direction, and perform character color change, character size change, shaded drawing, etc., and perform right-eye image drawing and left-eye image drawing processing. the

Also, when a part of a sentence (for example, NY) is displayed stereoscopically, a three-dimensional object character may be drawn superimposed on the drawing position of its adjacent character. Therefore, in making a sentence, the space between the three-dimensional object character and its adjacent characters can be increased. Of course, in a personal computer (character processor, etc.), when a target character is recognized based on its attribute information, an editing process of making the space between adjacent characters larger than usual may be automatically performed. In addition, transparency (M) can also be set as an attribute of a three-dimensional object character. For example, if a personal computer (character processor, etc.) sets the R pixel data of the enlarged object character designated transparently as R1, and the R pixel data of the overlapping character as R2, then it can be calculated by (R2×M/100+R1× (1-M100)) to obtain rendering R pixel data. This transparency setting can also be used in the case of displaying a three-dimensional object character in a color different from other characters. the

In addition, in the above example, a personal computer that recognizes and displays a file as an image is illustrated, but it is not limited thereto. Even as a digital broadcast receiving device capable of receiving and displaying data broadcasting (BML file) and having a network connection environment and an image A mobile phone with a display function can also constitute a stereoscopic video display device. the

As described above, if the characters or character strings constituting the article have a 3D effect, the visual effect of the article can be significantly improved. On the contrary, when the electronic text data is sent by e-mail or the like, there is no equipment for the display device on the receiving side. In the case of performing a 3D display function, there occurs a defect that the electronic text data cannot be displayed satisfactorily. the

As described above, electronic text data is often described in a format such as XML, and the above-mentioned 3D effect is realized by describing, for example, characters and character strings as attribute information. Therefore, if the attribute indicating the 3D effect is deleted from the electronic text data and changed to a character string attribute (without specifying any attribute) for normal two-dimensional display (2D display), even if the display corresponding to the receiving side is not provided, A function on the device that also displays received electronic text data as a usual character string. However, if so, there is also a possibility that the intention of the article author cannot be correctly conveyed to the receiver side. the

Hereinafter, other embodiments of the present invention will be described with reference to the drawings. First, FIG. 19 shows a functional block diagram of the text conversion processing tool of the embodiment. the

Furthermore, the functional block diagram shown in FIG. 19 can be realized by providing the same function to the CPU by installing a program or a database for jointly executing each function in the device. Here, these programs and databases may be installed in the device in advance, or may be installed separately from the outside. This installation can also be performed by installing a storage medium (disk, etc.) storing the program and database into the device, in addition to downloading from a public network such as the Internet. the

As shown in the figure, the text conversion processing tool is composed of a text search unit 201 , a text conversion unit 202 , and a conversion rule storage unit 203 . the

The text search unit 201 searches the input text data T1 for characters or character strings to which corresponding attribute information is added based on the conversion rule table stored in the conversion rule storage unit 203 . The text conversion unit 202 converts attribute information of characters or character strings retrieved by the text retrieval unit 201 based on the converter table stored in the conversion rule storage unit 203, and outputs the output text data T2. The text rule storage unit 203 stores a conversion rule table for converting predetermined attribute information into other attribute information among the attribute information of characters or character strings that can be included in the input text data T1. the

FIG. 20 shows a configuration example of a conversion rule table when the input text data T1 is 3D text data and the output text data T2 is 2D text data. In addition, here, 3D text data and 2D text data are described in the XML format. the

In this configuration example, the conversion rule table is configured to include: a conversion rule for converting a label giving a 3D effect to a character or a character string into a 2D decorative character (italic); and increasing the A conversion rule for the font size (attribute) of characters or character strings. Here, the font size is set such that only 1 pt (point) is increased per unit amount of flying out. the

In FIG. 20 , <text font=12pt> described in each text data indicates that the next data is text data with font size=12pt, and </text> indicates the end of the text data. In addition, <3D d=2> and <3D d=1> described in the 3D text data indicate that a 3D effect is given to the next character or character string, and the size of the amount of jumping out is set to level 2 (d=2 ) or level 1 (d=1). Here, the larger the level value, the larger the amount of flying out. the

In addition, <if font=14pt> and <if font=13pt> described in the 2D text indicate that the following characters or character strings are modified with italics (it: Italian font) with a font size of 14pt and 13pt,</ it> indicates the end of the text data. the

FIG. 21 shows a flow chart for converting the input text data T1 based on the conversion table. the

Once the conversion process starts, the input text data T1 (3D) is input to the text search unit 201 (S201), and among the characters or character strings in the input text data T1, the characters or character strings to which the 3D effect is added (S102 ). At this time, if there is a character string to which a tag for imparting a 3D effect is added, the flying amount of the character or character string is extracted at the same time. Then, the extracted information, the input text data T1 and the conversion rule table held in the conversion rule storage unit 203 are supplied to the text conversion unit 202 (S103). the

The text conversion unit 203 converts the label of the character or character string retrieved in S102 into italics (it: Italian font) according to the conversion rule table, and at the same time increases the font size of the character or character string by only the amount corresponding to the 3D pop-out amount. The points are converted into two-dimensional text data (S104). The transformed text data is then output as output text data T2. the

An example of display output in this case is shown in FIG. 22 . The lower left side of FIG. 22 is an example of display output when the input text data T1 (3D) is displayed in 3D, and the lower right side of the same figure is an example of display output when the converted output text data T2 (2D) is displayed in 2D. the

As shown in FIG. 22, according to the above-mentioned processing, a character string with a 3D effect can be displayed two-dimensionally (a part of the character string surrounded by a dotted line in the same figure) by using italic enlarged characters. During the display, it is possible to emphasize the character string to which the 3D effect is given. Therefore, the intention of the author who has completed the input of the document data T1 can be reflected on the two-dimensional display, and the author's intention can be appropriately conveyed even in a device without a two-dimensional display function. the

In addition, as described above, when converting 3D text data into 2D text data, both the character decoration method (Italian font) and the font size are converted, but even if only the character decoration method (Italian font) or only the font size is converted, Emphasis effects of 3D character strings can also be exerted. the

In addition, in the above content, it is assumed that the character modification method is italic (Italian font), and other character modification methods similar to 3D display, such as shaded characters and bold characters, can also be used. the

In addition, in the above content, the amount of the 3D effect flying out is represented by a simple numerical value (d=1, 2, ...), but it can also be described in units such as mm, cm, or "large", "medium", "Small" and other metric descriptions to express. Furthermore, even in this case, the size of the font size can be changed in dots according to the amount of jumping out. the

However, in the above, the conversion rule table for converting 3D text data into 2D text data was exemplified, and the processing flow and display output example using it were exemplified. However, the conversion rule table may be configured as follows: 2D text data A table converted to 3D text data. For example, contrary to the above, when a tag with 2D character decoration (for example, Italian font) is described in a character or character string, the conversion rule table includes a tag that converts the character or character string to give a 3D effect. In the conversion rule table of the label, or when attribute information that makes the font size of characters or character strings larger than usual is described, the conversion rule table may also include the conversion of the attribute information into the corresponding font size increase. Transformation rules for outputting attribute information for 3D display. the

For example, this transformation rule is contrary to the above. When the label modified by a character is italic (Italian font), if the label is converted into a 3D effect label with a pop-out amount corresponding to the font size, it can be specified. By converting the 2D text data shown in FIG. 22 into 3D text data of the same figure, as shown in the lower left side of the figure, these characters or character strings can be displayed in 3D with more impact than usual two-dimensional display. the

In addition, in the above content, the data is described in the XML format, but it can be implemented in any data format that partially adds attributes such as font, italics, or 3D to characters and character strings as decoration information. the

(Specific example) A specific example is shown when the above-mentioned text conversion processing tool is applied to a portable terminal device. FIG. 23 is a diagram showing the configuration of a portable terminal device. the

In addition, in this specific example, the above-mentioned text conversion processing tool is installed by downloading from the public network to the memory in the portable terminal device, for example, via the communication module 101 shown in FIG. 23 . In addition, it is assumed that the portable terminal device shown in FIG. 23 does not have a 3D display function, and therefore, the installed text conversion tool performs a function of converting 3D text data into 2D text data. the

As shown in the figure, the portable terminal device has: a communication module 101, a communication processing unit 102, an operation panel 103, an input processing unit 104, a monitor panel 105, a display control unit 106, a voice input and output device 107, a voice processing unit 108, and a CPU 109 , RAM110. the

The communication module 101 has a wireless communication module such as an antenna, and communicates with a public communication network via radio waves. The communication processing unit 102 performs processing corresponding to the communication protocol on the data transmitted and received via the communication module 101 . the

The operation panel 103 has an operation mechanism such as an operation key, and outputs a signal corresponding to an operation result to the input processing unit 104 . The input processing unit 104 converts the signal received from the operation panel 103 into data, and outputs the data to the CPU 109 . the

The monitor panel 105 has a display mechanism such as a liquid crystal monitor, and displays a display screen corresponding to processing from the display control unit 106 . Display control unit 106 generates a display screen based on image data input from CPU 109 and displays it on monitor panel 105 . the

The sound input and output IF (interface) 107 has the interface for inputting and outputting the sound, outputs the sound signal input by the sound input mechanism to the sound processing part 108, and outputs the sound corresponding to the sound signal received from the sound processing part 108 by the sound output mechanism . Audio processing unit 108 converts audio signals received from audio input/output IF 107 into audio data and outputs them to CPU 109 , and converts audio data received from CPU 109 into audio signals and outputs them to audio input/output IF 107 . the

CPU 109 executes various processes according to various programs installed in the portable terminal device. RAM 110 sequentially stores various data processed by CPU 109 . the

For example, when e-mail data including a text data file is received from a public network, the e-mail data is acquired and analyzed by CPU 109 according to an e-mail processing program, and stored in RAM 110 . At this time, if the text data file stored in RAM 110 is 3D text data, it is converted into 2D text data by CPU 109 according to the text data conversion processing program, and stored in RAM 110 as another file. In addition, this conversion process is performed with reference to what was demonstrated to FIG. 19 or FIG. 22 mentioned above. the

Thereafter, when a display operation command for the text data file is input through the operation panel 103 , the CPU 109 reads the 2D text data from the RAM 110 to generate image data, and outputs it to the display control unit 106 . After receiving it, the display control unit 106 generates an image corresponding to the 2D text data and displays it on the monitor panel 105. Thereby, for example, an image shown on the lower right side of FIG. 22 is displayed on the monitor panel 105 . the

In addition, in this embodiment, an application example of the above-mentioned embodiment is described by taking a portable terminal device without a 3D display function as an example. However, when the above-mentioned embodiment is applied to a portable terminal device with a 3D display function, the 3D text The text conversion tool for the function of converting data into 2D text data is installed on the mobile terminal device to execute the function of converting 2D text data into 3D text data. At this time, when the text data file received by e-mail is 2D text data, the text conversion tool is activated, and the CPU 109 executes the process of converting the 2D text data into 3D text data. Then, the converted 3D text data is stored in RAM 110 as another file, and the conversion processing is as described above. the

In addition, at this time, the text data can be displayed and output regardless of the 3D/2D representation. Therefore, it is also possible to ask the user which display mode to use, and to appropriately set the display output mode 3D/2D according to the corresponding selection instruction. Alternatively, the display may be normally displayed in 3D and changed to 2D according to a switching command from the user, and conversely, the display may be normally displayed in 2D and changed to 3D according to a switching command from the user. the

In addition, regardless of the case of the present embodiment, any text data in 3D/2D can be sent to the transmission destination at the time of e-mail transmission. Therefore, at the time of e-mail transmission, the user may also be asked what kind of text data to send. the

In addition, in addition to e-mail data, even when viewing a homepage with a 3D tag, the conversion process described above can be performed according to the 3D/2D display method of the receiving terminal. the

As mentioned above, although embodiment of this invention was described, this invention is not limited to the said embodiment, It goes without saying that other various changes are possible. The embodiments of the present invention can be appropriately modified in various ways within the range of technical ideas shown in the scope of claims. the
