[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a stereoscopic image generation apparatus. In particular, the present invention relates to a stereoscopic image generation apparatus in a stereoscopic image display apparatus that can observe n-eye stereoscopic vision.
[0002]
[Prior art]
In recent years, development of a stereoscopic image display apparatus that enables an observer to perform stereoscopic observation without using a special instrument has been advanced. The principle of such a stereoscopic image display device uses binocular parallax generated by the distance between the right eye and the left eye, and displays different parallax images for the right eye and the left eye on a stereoscopic display element (display) having a lenticular or parallax barrier. Giving the viewer a sense of stereoscopic vision.
[0003]
By extending this principle and providing a stereoscopic image display device corresponding to a plurality of viewing angles with different parallax images for the right eye and the left eye for each viewing angle, an n-eye stereoscopic image display device can be obtained.
[0004]
FIG. 1 is a diagram illustrating a specific example of a parallax image. S = 0 to 3 are collections of images having different parallax angles when the objects in the three-dimensional space are observed while changing the viewing direction. Each image is a collection of pixels having coordinates x and y, which are composed of RGB components that are the three primary colors of light.
[0005]
Such a parallax image can be generated by calculating and visualizing a three-dimensional space virtually modeled by computer graphic (CG) technology, or by digitizing an image taken by a video camera or the like.
[0006]
In a stereoscopic image display device, a group of such parallax images is decomposed at the color component level, and an image synthesized according to a different rule depending on the barrier shape of the stereoscopic display element (display) is displayed on the stereoscopic display element, so that the observer can A realistic image can be sensed (for example, Patent Document 1). The rule that varies depending on the barrier shape is referred to as a stereoscopic image format in the following description.
[0007]
Therefore, in the stereoscopic image display device, a process of converting to a stereoscopic image format corresponding to a stereoscopic display element that uses parallax image data is necessary. As a method of this processing, for example, there is a method in which pixels of a parallax image are once written in a frame buffer, and then color components are recombined so as to match a stereoscopic image format (for example, Patent Document 2).

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, a case where stereoscopic display using four viewing angles is performed will be described as an embodiment of the present invention. However, the application of the present invention is not limited to the case where four viewing angles are used. By applying the principle of the present invention so as to correspond to the stereoscopic image format required by the stereoscopic display element, one or more n-eye type is applied. It is applicable to.
[0021]
In the following description, each parallax image number is set to S = 0 to 3 as a parameter for distinguishing four parallax images corresponding to four viewing angles. Each parallax image has the same number of pixels as the stereoscopic display element (display).
[0022]
The stereoscopic image generation apparatus according to the present invention has a function of converting into a stereoscopic image format required by the stereoscopic display element, for example, an image format shown in FIG.
[0023]
FIG. 3 is a block diagram of a stereoscopic image generating apparatus according to the present invention. In FIG. 3, a block 1 is a stereoscopic image generation device according to the present invention, and a parallax image 10 is given as an input, and the stereoscopic image format shown in FIG. 2 is generated and repeatedly output to the corresponding stereoscopic display element 11. A stereoscopic image is displayed. In FIG. 3, arrows between blocks indicate the flow of data.
[0024]
As shown in FIG. 1, four parallax images 10 corresponding to four viewing angles are input to the color buffer 100 of the stereoscopic image generation apparatus 1. Here, as described above, the parallax image 10 can be generated by calculating and visualizing a three-dimensional space virtually modeled by the CG technique, or by digitizing an image taken by a video camera or the like. Therefore, since the formation of such a parallax image is not directly related to the present invention, the description of the formation method is omitted.
[0025]
FIG. 4 shows an example configuration of the color buffer 100. Each pixel RGB of the parallax image shown in FIG. 1 is input to the color buffer 100 together with the parallax image number S and the coordinates x, y on the parallax image as parameters.
[0026]
The input pixel RGB is input to the decoder 101 and stored in the corresponding position of the color buffer memory 102 determined according to the coordinate x. Thereby, parallel conversion is performed in a state where four pixels are continuous in the x direction. If the parallax image 10 is input in this state from the beginning, the color buffer memory 102 can be omitted.
[0027]
Further, when the pixel is parallel-converted by the decoder 101, the coordinates x and y and the parallax image number S when the coordinate x is a multiple of 4 are buffered in the corresponding buffer memories 103, 104, and 105, respectively. Here, as long as the order of input pixels is within a range in which parallel conversion is normally performed, the order of the coordinates of the input pixels and the parallax image numbers are not limited.
[0028]
Next, the input pixel is output together with the coordinates x and y and the parallax image number S from the color buffer memory 100 for each color component after the parallel conversion is completed. As shown in FIG. 4, the pixels separated for each color component are shown as R0 to R3, G0 to G3, and B0 to B3 in association with the x coordinates of the original pixels.
[0029]
FIG. 5 shows a stereoscopic image generation unit 110, which is a central part of the present invention. The stereoscopic image generation unit 110 corresponds to a stereoscopic image format corresponding to coordinates x, y and parallax image number S from color components R0 to R3, G0 to G3, and B0 to B3 input in parallel from the color buffer memory 100 of FIG. Select and output color components to match
[0030]
At this time, an address stored in the frame buffer 120 is generated during the period until the color component selected and output is displayed. This process is performed for each of the R, G, and B color components. Therefore, as shown in FIG. 5, pixel generators 111, 112, and 113 are provided corresponding to the R, G, and B color components. Since each of the pixel generators 111, 112, and 113 has essentially the same configuration, details of the pixel generator 111 corresponding to the R component shown in FIG. 6 will be described as a representative.
[0031]
The actual color component selection and address generation are performed in the address generation unit 111c based on the value Tr referring to the table value preset in the table 111a by the coordinates x, y and the parallax image number S.
[0032]
According to the principle of a known stereoscopic display element, the selected color component is one pixel out of the four pixels input in parallel, and the address stored in the frame buffer 120 is the original parallax image of the selected color component Generate the same coordinates as above. Thereby, it can be stored in the frame buffer 120 without overlapping with the processing result of other pixels.
[0033]
FIG. 7 is an example of the truth table of the output Tr from the table 111a. An output Tr is set corresponding to the combination of the coordinate y and the parallax image number S. In this embodiment, the coordinate x is irrelevant to the determination of the output Tr, but more generally the coordinate x is also related.
[0034]
In FIG. 7, the same applies to the corresponding pixel generators 112 and 113 for the other color components G and B, and the output Tg from the table in the pixel generators 112 and 113 corresponding to the table 111a of the pixel generator 111, An example of the truth value of Tb is shown simultaneously.
[0035]
By the output Tr, one pixel is selected from the four pixels R0, R1, R2, and R3 corresponding to the parallax image numbers S = 0 to 3 in the R component by the 4-to-1 selector 111b. FIG. 8A in FIG. 8 is a truth table of the output R output from the selector 111b. Similarly, FIGS. 8B and 8C are truth tables of outputs G and B output from selectors corresponding to the selector 111b in the corresponding pixel generators 112 and 113 for the other color components G and B, respectively.
[0036]
Next, the address generator 111c generates and outputs an address Ar as a function of x, y, and T according to the following relational expression.
[0037]
Ar (x, y, Tr) = w × y + x + Tr
However, w is a constant and the x size of the parallax image, and x is a multiple of 4 at the output stage from the color buffer 100. Similar processing is performed for the pixel generators 112 and 113 only by the difference that the output from the table becomes Tg and Tb.
[0038]
At this stage, color components that are not required to be included in the pixels to display a stereoscopic image are removed. For this reason, access to the frame buffer 120 is much less than in the conventional system in which the color components are recombined so as to match the stereoscopic image format after the pixels of the parallax image are written in the frame buffer 120, and the bandwidth and capacity are greatly increased. It can be easily understood that performance improvement can be obtained. Thereby, the real-time property of the stereoscopic image display can be dramatically improved.
[0039]
The table 111a can be arbitrarily reset by configuring it with a memory. For this reason, in the system to which the present invention is applied, the stereoscopic display element (display) to be adopted is changed, and the required stereoscopic image format is changed accordingly, or a general display not intended for stereoscopic display. Even for this, it is possible to easily cope with the problem by resetting the table 111a.
[0040]
Furthermore, depending on the observation position of the observer, there may be a state called reverse viewing in which the parallax images to be observed by the left and right eyes are reversed. Depending on the observation position of the observer, Tr, Tg, Tb This reverse viewing state can also be corrected by dynamically modifying and changing the output table.
[0041]
The result of performing the above processing for all the pixels of all the parallax images is shown in FIG. 18, and this is the drawing state of the frame buffer 120.
[0042]
In FIG. 18, as shown in FIGS. 18A, 18B, and 18C, the frame buffer 120 records the R, G, and B color components processed by the stereoscopic image generation unit 110 in FIG. 5, respectively. It is composed of three banks corresponding to the color components.
[0043]
The reason why the banks are independent in this way is to cope with the fact that the addresses to be recorded differ for each color component as a result of processing by the stereoscopic image generation unit 110.
[0044]
In FIG. 18, it can be seen that the same state as the stereoscopic image format shown in FIG. 2 is obtained by extracting the color component of the same coordinates from each bank.
[0045]
In FIG. 2, for example, R000, G001, and B002 are stored at buffer positions corresponding to coordinates (x, y) = 0,0. Comparing this with the parallax image in FIG. 1, R000 is the R component included in the pixel with the parallax number S = 0 (x, y) = 0, 0, and G001 is the coordinate with the parallax number S = 1 (x Y) = 0, 0 is a G component included in a pixel, and B002 is a B component included in a pixel having a parallax number S = 2 coordinates (x, y) = 0, 0.
[0046]
FIG. 9 shows an example configuration of the display controller 130. In the display controller 130, the HV counter 131 periodically counts up in response to the horizontal-vertical synchronization signal, and the horizontal and vertical synchronization signals H-Sync, V-Sync and the like necessary for the display of the stereoscopic display element 11 are displayed. The display coordinates h and v are converted into addresses (Ar, Ag, Ab) on the frame buffer 120 of the three banks shown in FIG. 2 by the read interface 132, and the color components RGB of the corresponding addresses are read out.
[0047]
Here, Ar = Ag = Ab = w × v + h where w is a constant and x size of visual field coordinates.
[0048]
As described above, the address is common across the three banks. The read out pixel RGB is output to the stereoscopic display element 11 together with the synchronization signal and displays a stereoscopic image for the observer.
[0049]
Here, in the stereoscopic image generating apparatus shown in FIG. 5, the color components stored at the same address over the three banks are output so as to be the color components constituting the pixels of the same coordinates on the stereoscopic display element 11. I have to.
[0050]
For this reason, since the pixels are arranged in the stereoscopic image format required by the stereoscopic image display element 11 at the stage stored in the frame buffer 120, each bank of the frame buffer 120 is displayed at the stage of displaying on the stereoscopic image display element 11. Thus, it is possible to cause the observer to observe a stereoscopic image only by giving the same address in order and outputting the read color components to the stereoscopic image display element 11.
[0051]
Here, in the embodiment described above, since the frame buffer 120 has a three-bank configuration, there is a problem that the number of memory elements and buses for accessing the memory element increase.
[0052]
Therefore, an embodiment in which the frame buffer 120 is constituted by one bank will be considered below. FIG. 10 shows a configuration block diagram of the stereoscopic image generating apparatus 1 configured to use the frame buffer 120 as one bank.
[0053]
From the principle of a known stereoscopic display element, only one R, G, B color component is extracted from each of four consecutive pixels in the x direction belonging to the same parallax image. For this reason, three R, G, and B color components generated by the stereoscopic image generation unit 110 shown in FIG. 3 are recorded together at the same address on the frame buffer.
[0054]
Specifically, three color elements generated by the stereoscopic image generation unit 110 of FIG. 5 are stored together in the same address on the frame buffer 120, and the frame buffer is one bank as shown in FIG. It is a configuration.
[0055]
Instead of the stereoscopic image generation unit 110 in FIG. 5, in the embodiment of the stereoscopic image generation device 1 in FIG. 10, the stereoscopic image generation unit 110 is configured as shown in FIG. 11. The stereoscopic image generation unit 110 in FIG. 11 includes an address generator 114 and pixel generators 111, 112, and 113 corresponding to the R, G, and B color components.
[0056]
Since each of the pixel generators 111, 112, and 113 has essentially the same configuration, FIG. 12 representatively shows the configuration of the pixel generator 111 corresponding to the R component. The pixel generator 111 is basically the same as that of the embodiment shown in FIG. 6, but since there is an independent address generator 114 as described above, each pixel generator has an address generator 111c. It is unnecessary. The table 111a and the 4-to-1 selector 111b are the same as described with reference to FIG. The same applies to the G and B components.
[0057]
Here, the address A output from the address generator 114 in the stereoscopic image generation unit 110 in FIG. 11 is obtained by adding an offset based on the parallax image number of the parallax image to the x coordinate of the input pixel as follows. Ask for it.
[0058]
A = w ^* y + x + S
However, w is a constant and x size of the parallax image, and x is a multiple of 4 at the output stage from the color buffer 100.
[0059]
FIG. 13 shows a drawing state of the frame buffer 120 after processing all pixels of all parallax images in the stereoscopic image generating apparatus 1 of FIG. As shown in FIG. 13, the frame buffer 120 has a one-bank configuration.
[0060]
Here, it is important to be able to create a state equivalent to the frame buffer of FIG. 2 by recombining the color components included in the four pixels continuous in the x direction. The color component is selected from the four pixels so as to conform to the stereoscopic image format and output to the stereoscopic display element 11.
[0061]
In the embodiment of FIG. 10, in order to perform such control, the display controller 130 is configured as shown in FIG. In FIG. 14, in the display controller 130, the HV counter 131 periodically counts up, and generates synchronization signals H-Sync, V-Sync and display coordinates h, v necessary for displaying the stereoscopic display element. Yes.
[0062]
The display coordinates h and v are converted by the read interface 132 into an address A on the frame buffer 120 having a single bank configuration shown in FIG. 13, and the pixel RGB at the corresponding address is read from the frame buffer 120.
[0063]
Here, A = w × v + h where w is a constant and x size of the visual field coordinates.
[0064]
The read pixels RGB are again added with display coordinates h and v by the read interface 132 and output to the display buffer 140. The synchronization signal is output in consideration of the latency until the pixel is output to the stereoscopic display element 11.
[0065]
FIG. 15 shows a configuration example of the display buffer 140. The input pixel RGB passes through the decoder 141 and is stored in the buffer 142 corresponding to the input display coordinate h, so that it is parallel-converted into a state in which four pixels are continuous in the h direction. The buffer 142 is composed of a plurality of banks, and also serves to buffer the time until pixels are read from the frame buffer 120 and to output pixels continuously to the subsequent stage.
[0066]
Further, when the pixel is converted into parallel, the display coordinates h and v when the coordinate h is a multiple of 4 are also buffered in the buffers 143 and 144, respectively. The pixels separated for each color component are R0 to R3, G0 to G3, and B0 to B3 corresponding to the h coordinate of the original pixel.
[0067]
FIG. 16 is a configuration example of the stereoscopic image regeneration unit 150. The stereoscopic image regeneration unit 150 uses color components R0 to R3, G0 to G3, and B0 to B3 that are input in parallel from the display buffer 140 of FIG. 15 to match the stereoscopic image format according to the display coordinates h and v. Are output while being selected by selectors 151, 152, and 153.
[0068]
Four pixels can be output to the stereoscopic display element 11 by one input, and a new input is repeatedly obtained from the color buffer 100 each time four pixels are output. In the stereoscopic image regeneration unit 150, selection of color components is performed for each color component. Since the selectors 151, 152, and 153 corresponding to the RGB components are essentially the same, only the R component is representatively shown in FIG.
[0069]
The actual color component is selected by referring to the table value of the table 151a based on the display coordinates h and v input by the 4-to-1 selector 151 together with the color components R0 to R3. The same processing is performed for the G and B components only with different outputs from the table.
[0070]
These tables can be set arbitrarily. In addition, by the setting of such a table, it is possible to perform the response when the stereoscopic display element 11 is changed and the correction of the reverse viewing state with the same mechanism as the stereoscopic image generating apparatus 1 of FIG.
Finally, the stereoscopic display element 11 displays a stereoscopic image to the observer based on the synchronization signals h and v output from the display controller 130 and the color components output from the stereoscopic image regeneration unit 150 in FIG. Can do.
[0071]
Further, in the above embodiment, in writing to and reading from the frame buffer, a different offset is added to each address to be accessed, and the offset is appropriately controlled to wait for reading for display to be completed. If the configuration is such that the next and subsequent frames can be drawn to other addresses on the frame buffer, the real-time property of the stereoscopic image display can be further enhanced.
[0072]
【The invention's effect】
As described above with reference to the drawings, the stereoscopic image generating apparatus according to the present invention significantly reduces the access to the frame buffer and provides a significant performance improvement. As a result, the real-time property of the stereoscopic image display is improved. It is possible to provide a stereoscopic image display device that can be dramatically improved.
