[Prior Art] The reason why human beings have three-dimensional vision is that human eyes can independently observe the scenes of the outside world, that is, the left eye sees the scene of the left eye, and the right eye sees the scene of the right eye. The gap 'and then through the natural fusion of the brain (fUsing), can be in the big - ' - - ' · · · · The brain presents a three-dimensional scene. · · 3D stereoscopic display (stereo display) is to let the left and right eyes respectively to the angle of the left eye with a difference in angle and reduce the image of the right eye, so that a viewer can see. -' ^ ' ;;'/... Γ-stereoscopic image. In order to achieve this goal, one method allows the display to alternately display the reduced left eye image and the reduced right eye image, and the viewer wears the LCD lens (LCD shutter, ', · ' —, /' f,, :: \ Glasses), the left and right lenses alternately allow light to pass through, and the switching action is synchronized with the vertical retrace (vertica丨retrace) of the display *^, *j\/, two: In this way, when the switching frequency is 'high to a certain degree', the viewer can view the stereoscopic image. i·. .· νf .: two?

So, narrow the left eye #like 1280044 兴The amount of data for reducing the image of the right eye can be reduced to half of the original image. Referring to Figure 1, the display 8 with a resolution of l〇xl〇 (that is, the display screen has a total of 10 columns) is taken as an example, when interlaced display is used. In the technology, the video memory (vide〇me_y) r stores two reduced left eye images u and reduced right eye images 12 with an image size of 10x5. When the reduced left eye image is displayed, the columns of the left eye image u are reduced. They are displayed on columns 3, 5, 7 and 9 of the display, respectively, and columns 2, 4, 6, 8 and 10 can be blank. Similarly, when the image of the right eye is reduced, the image of the right eye is reduced. The columns of 2 are displayed on the 2nd, 4th, 6th, 8th and 10th columns of the display respectively. The columns 3, 5, 7 and 9 can be the implementation of the hollow parental error. ", for example, column blank (Une_blanking) and double sync (sync-doubling), etc.. However, in the prior art, when the 3D image is displayed by the interlaced display technique, the reduction of the left eye image and the reduction of the right eye image need to be processed in advance. The New (4) domain quickly generates .3D stereoscopic images, for example, the respective stomach frames are used in soft ages. mckering ^ How to speed up the instantaneous speed of the interlaced display technology has become an important issue to be solved

Display area The number enables the columns of the reduced left eye image and the reduced right eye image to reach the display area in an interlaced manner. The size of the reduced left eye image and the reduced right eye image in the vertical direction can be reduced to the display area in the vertical direction. Half of the size. The size of the reduced left eye image and the reduced right eye image in the horizontal direction may be the same as the size of the display area in the horizontal direction. The interlaced stereoscopic image generating device may further include a memory device that stores the foregoing The left eye image is reduced and the right eye image is reduced. The memory device can have two page frame buffers, one of which stores the reduced left eye image and the reduced right eye image currently displayed, and the other stores the reduced left eye image. And narrowing down the right eye image. The memory device still uses dance state random access memory (DRAM) or synchronous dynamic random access memory (SDRAM), etc. The I member display area can be located in a micro-retarder. Display: The micro retarder makes the odd-numbered columns of the display area and the even-numbered columns have the same polarization, and the lions with different polarization directions through the left and right lenses Glasses, the viewer's left and right (four) can be different images 'that is, the left eye only sees the left eye image, the right eye only sees the right eye shadow> image. ^ According to the present invention, the winter interlaced stereo image generation method The short image and the reduced left eye image and the reduced right eye image are stored in two adjacent plate segments after generation. When the stereo image a temple is displayed, the two recorded segments are blessed. Controlling a display area to be depleted; a list of numbers, the method provided by the present invention enables the winter column of the reduced left eye image and the reduced right eye image to arrive at the display area in an interlaced manner. :/ : 乂/:^ At the beginning of the scanning memory section Before the segment, the counter that controls the column number is reset to zero. The counter is incremented before displaying one of the reduced left eye images or the reduced right eye image. When the memory device has two page frame buffers, the method provided by the present invention can first determine which block in the page buffer storage process to process before preparing the image of the mound.

Processing and displaying stereoscopic images, the efficiency of image processing and display can be improved while reducing the amount of memory used. [Embodiment] Hereinafter, an apparatus and method for generating an interlaced stereoscopic image according to a preferred embodiment of the present invention will be described with reference to the accompanying drawings, wherein the same elements will be described with the same reference numerals. Referring to FIG. 2, an interlaced stereo image lacking device according to a preferred embodiment of the present invention is implemented in a computer system, and mainly includes a memory device, a memory device controller 2, and a stereoscopic image engine (3D graphics). Engine) 3, and an interleaved data processor 4. The device cooperates with a display 8 and a polarized glasses 9 . The display 8 is provided with a micro retarder (mkro_retander) 81. The memory device 1 can be any device capable of storing image data. For example, dynamic random access memory (DRAM) or synchronous dynamic random access memory (SDRAM). In the present embodiment, the memory device 1 has two page buffers, namely a page frame buffer area and a page frame buffer port. When the stereoscopic animation is played, the page frame buffer Α stores the reduced left eye image Ua of the currently displayed page frame to reduce the right eye image 12a, and the page frame buffer B is stored for a page frame to be displayed. The left eye image Ub is reduced and the right eye image i2b is reduced. :: The memory device controller 2 controls the data access and movement in the memory device 1, which accepts and interprets the requests of other components, and confirms that the data is in the memory device - * ' ' -^ , ' two ^ ; * Set the address of t to read data from the memory device, or write data to the memory device. ' * , , · . The stereoscopic image engine 3 receives the video source data (video source 1280044 data) transmitted via the bus bar and converts it into a reduced left eye image and a reduced right eye image with an angular difference. The stereo image engine 3 can be a microprocessor generally disposed on a display card for processing 3D graphics, or a software or hardware module having similar functions. In the present embodiment, a micro retarder 81 is disposed on the screen of the display 8, so that the polarization directions of the odd-numbered columns and the even-numbered columns on the screen of the display are different. The viewer wears p〇larized glasses 9 when viewing the display displayed on the display. The left and right lenses of the polarizing glasses 9 have different polarization directions, so that the viewer's left eye receives only an odd number of images, and the right eye receives only an even number of images. It should be noted that the display 8 is an LCD display with a delay and selects an analog or digital input signal according to the specifications of the LCD display itself. The interleaved data processor 4 stores the reduced left eye image and the reduced right eye image in two adjacent memory segments through the memory device controller 2. Referring to FIG. 3, in the embodiment, when the stereo image is generated, the geometric size of the video source material 14 is first reduced to the original half in the vertical direction. Therefore, when the reduced left eye image u and the reduced right eye image 12 are generated, the generated reduced left eye image 11 and reduced right eye image 12 are vertically oriented. The size of the left eye image 11 is only 14 4 W 11 * The right eye image 12 is stored in One of the two page frame buffers of memory device i is stored in two adjacent memory segments. :, - * , ^ 1 r .: When outputting the image to the display area of the display 8, the ___▲_, ' The 12th will be read in the wrong way. When scanning the first column of the page buffer, the first column of the left eye image ιγ will be scanned first, then the second image of the right eye will be reduced. - Column tilt scan. In this way, when the output is suppressed, the first column of the display area on the hemp 8 is reduced to the left eye image (10) column _ column, and the first column of the display region on the g 8 display is 7F to reduce the size of the right eye image 12 - column. Hey, when the second column of the junk box buffer is in the system, the left county image (10) is second to the first, and the second column of the 12th ancient eye shadow 1280044 is scanned. Thus, when outputting to the display 8, the third column of the display area on the display 8 will display the second column of the reduced left eye image Η, and the fourth column of the display area will display the second column of the reduced right eye image 12. When scanning the page frame and the crane area, the count number of the || 6 (four) indicator 8 is displayed so that the image data transmitted in the order of first in first out (FIFO, first-in, first-out) is correctly displayed. On the display 8. When the columns of the page frame buffer are scanned, the screen displayed in the display area is as shown in Fig. 3. The odd column displays the columns of the left eye image U, and the even columns shows the columns of the reduced right eye image 12. As described earlier, in conjunction with the micro retarder 81 and the polarized glasses 9, the viewer's left eye receives only an odd number of images, and the right eye receives only an even number of images. In this way, the viewer will perceive a three-dimensional image. • Please refer to Figure 4 'When receiving the ij video source data, the stereo image engine will first reduce the thickness of the video source data in half of the vertical direction (step 4〇1), and then view the source data. The geometric information in the middle generates a vertical image: a reduced left eye image and a small image of the listening image:: Small right eye image (steps. Because of the size of the video source data in the vertical direction, It is reduced, so - the left eye image and the reduced right eye image are both ' · : the reduced image . / ; · - :;·./.

For example, if The front side shows w stereoscopic image: like the frame buffer buffer Α output', then the stereoscopic image engine 3 can store the processed image data in the page frame buffer 。. When the image data in the page frame buffer 处理 is processed After that, the display 8 can output the image data in the frame buffer buffer. At this time, the stereoscopic image engine 3 can store the image data of the 4 command in the page buffer a. Wide, :. -* ' - -, ,, after the 'suffixed page frame buffer for storing image data, processing The reduced left eye image and the reduced right eye image are stored in adjacent memory segments in the page frame buffer (step 1280044 4〇4). Then, after adjusting the display update speed and other factors, if you want to process After one page frame, the process returns to step 40. Otherwise, the preparation process of the page pivot is completed (step 4〇5). Referring to FIG. 5, when the vertical image is displayed, the interlaced stereo image according to the preferred embodiment of the present invention The generating device first rides the count to zero (step 5G, money is scanned from the starting position of the page buffer) (step 5G2). Since the zoomed left eye image and the reduced right eye image are stored in the phase In the adjacent memory segment, when the first column of the page frame buffer is scanned, the first column of the reduced left eye image and the first column of the reduced right eye image are sequentially read. At this time, the first column will be recorded.

If the reduced left eye image and the reduced right eye shadow in the other page frame buffer have been overtaken; when finished, the page frame buffer switching action is performed (step 5U), for example, the memory of the scan The device address indicator points to the start bit of another page frame buffer. If the current page frame buffer has been scanned and does not switch to another page frame buffer, it is judged whether the playback has been completed. If the reason for not switching to another page frame buffer is that the data stored in the current page frame buffer is already the last page frame, the entire stream is ended. If the reason for not switching to another page frame buffer is that the data 1280044 in the next page buffer is not ready, the reduced left eye image and the reduced right eye image in the current page frame buffer will be displayed again on the display. . According to the embodiment, when a plurality of page frames are continuously played, for example, when the animation is played, the processes of the above FIG. 4 and FIG. 5 may be performed simultaneously. In other words, the method for generating the interlaced stereo image disclosed in the embodiment is to simultaneously prepare stereoscopic image data in a page buffer and display image data of another frame buffer to the display. In this way, the image processing speed can be speeded up, and the probability of image delay when playing an animation is reduced. It is to be understood that those skilled in the art will be able to make various modifications and changes in the above described embodiments without departing from the spirit and scope of the invention. For example, the apparatus for generating an interlaced stereoscopic image provided by the present invention can also be implemented in a television set, a video game instrument, or any other electrical appliance having an image display function. Further, in the above embodiment, the memory device is a Wei Chong area: architecture. However, those skilled in the art may also employ other buffer architectures' such as using a single-page buffer to display stereoscopic views. Accordingly, the foregoing is illustrative only and not limiting.
