IMAGE DISPLAY

摘要

An image display comprising a first lookup table memory (4) for correcting the gradation of a displayed image by correcting the gamma curve of an input video signal a second lookup table memory (5) for generating uniformity correction data on the uniformity on a screen for every gradation, and a position information generating unit (10) for generating the uniformity correction data corresponding to the screen position. The uniformity correction data outputted from the second lookup table memory (5) and that outputted from the position information generating unit (10) are combined by a correction data generating unit (6). The gradation-correction video signal that is as read from the first lookup table memory (4) is corrected by an operating circuit (7) by using the uniformity correction data outputted from the correction data generating unit (6), so that the uniformity correction of the displayed image is made for all the gradations.
