Abstract:
1. An image display apparatus comprising: an image display element; an optical system for observation of an image displayed on the image display element; a processor which performs 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 displays an image subjected to the distorting processing on the image display element; and a filter which provides a low-pass filter effect to the image that is observed through the optical system, wherein, when a first image region that includes a first number of pixels in the input image is converted into a second image region that includes a second number of pixels by the distorting processing, the filter provides the low-pass filter effect depending on the relationship between the first number of pixels and the second number of pixels to the second image region that is observed through the optical system.
