  • Patent number: 7034819
    Abstract: An apparatus for generating an interleaved stereo image includes a 3D graphics engine, an interleaved data merger and a register. The 3D graphics engine generates a shrunken left-eye image and a shrunken right-eye image of a stereo image based on video source data, the vertical sizes of the shrunken left-eye image and the shrunken right-eye image are shrunk compared with the vertical size of the video source data. The interleaved data merger stores the shrunken left-eye image and the shrunken right-eye image into two consecutive memory segments, and scans the memory segments while displaying the stereo image. A register controls a line number of a display region, so that the rows of the left-eye image shrunk and the right-eye image shrunk arrive at the display region in line-interleaved order. The invention also discloses a method for generating an interleaved stereo image.

  • Patent number: 7027664
    Abstract: A method for removing noise regions in a stereo 3D image, which includes a first eye image and a second eye image is achieved by calculating a maximum offset value and turning a horizontal synchronization signal and a display enable signal of the CRT timing parameters.

  • Patent number: 6577307
    Abstract: An anti-aliasing process without sorting the polygons in depth order to improve the image quality in three-dimensional graphics system. This method comprises extra buffer memory than does a typical three-dimensional graphics display system. The Z buffer stores the depth value of nearest pixel in front Z buffer and depth value of secondary nearest pixels in back Z buffer. The color buffer stores foreground color and background color. A weighting value is used and stored in the frame buffer to blend the foreground color and the background nearest color. The weighting value is associated with each pixel, it indicates the percentage of coverage of a pixel. Every pixel in Z buffer test stage will update the depth of the nearest pixel and the depth of the second nearest in Z-buffer, foreground color and background color in the frame buffer and the weighting value according to the result of depth comparison.

  • Publication number: 20030103062
    Abstract: An apparatus for controlling a display, which includes an on-screen buffer, two overlay buffers and a stereo window controller. The on-screen buffer stores screen image data that includes image data of an overlay region. The two overlay buffers are of a double-buffered architecture, and one overlay buffer stores the left image data and the right image data of a current frame, and another overlay buffer stores the left image data and the right image data of a next frame. The stereo window controller controls swap operations and overlay operations, wherein the swap operations determine which one of the two overlay buffers stores the left image data and the right image data of the current frame, and the overlay operations alternatively output the left image data and the right image data of the current frame while the overlay region is being scanned.
