  • Patent number: 7821475
    Abstract: The image display apparatus is capable of reducing moire fringe when electric inverse-correction is performed on an image output to an image display element. The apparatus includes an optical system for observation of an image displayed on an image display element, a processor performing distorting processing that electrically provides to an input image a distortion in a direction inverse to that of distortion as aberration generated by the optical system, and a filter providing a low-pass filter effect to the image observed through the optical system. When a first image region including a first number of pixels in the input image is converted into a second image region including a second number of pixels by the distorting processing, the filter provides the low-pass filter effect depending on the relationship between the first and second numbers of pixels to the second image region.
