  • Patent number: 6914616
    Abstract: An image display apparatus of the present invention includes an image display unit and an image reproduction module that generates display video data, which is to be displayed on the image display unit. The image reproduction module has an image transition controller that uses a predetermined image selection mask to process a first image and a second image and thereby generate the display video data in the case of changing display on the image display unit from the first image to an image including the second image in at least part of a display area of the first image. The image transition controller includes: a storage module that stores therein the first image, the second image, and a base selection mask having an image area of a smaller size than the at least part of the display area; and a selection mask conversion module that converts the base selection mask into the image selection mask having an image area of an identical size with the at least part of the display area.

  • Patent number: 6507346
    Abstract: The invention concerns the occurrence of flicker being reduced when an interlaced image signal is converted into a non-interlaced signal and displayed at a desired magnification. Correction coefficients corresponding to the respective even-numbered fields and odd-numbered fields are determined according to the magnification of an image and stored in an ODD coefficient memory and an EVEN coefficient memory. For each process for outputting image data corresponding to each pixel in each line of a liquid-crystal display panel, a corresponding correction coefficient is read from the ODD coefficient memory or the EVEN coefficient memory and provided to an interpolation processing circuit. The interpolation processing circuit interpolates image data of one pixel from image data of four pixels read from a line memory.
