Patent ID: 8913075

Claim:
An image display apparatus comprising: a holding unit that holds, for each combination of a possible luminance value of an image signal of a preceding frame to be reproduced first out of two adjacent frames and a possible luminance value of an image signal of a succeeding frame to be reproduced later than the preceding frame out of the two frames, a correction value used to correct a luminance value indicated by the image signal of the preceding frame to make the luminance value indicated by the image signal of the preceding frame more closely match a luminance value indicated by the image signal of the succeeding frame; a first acquisition unit that acquires image signals of successive frames; a second acquisition unit that acquires, from said holding unit, a correction value corresponding to a combination of a luminance value indicated by an image signal of an nth (n is a natural number of not smaller than 1) frame acquired at the nth turn by said first acquisition unit and a luminance value indicated by an image signal of an (n+1)th frame acquired at the (n+1)th turn by said first acquisition unit; and an output unit that adds the correction value acquired by said second acquisition unit to the luminance value indicated by the image signal of the nth frame, and outputs an image signal having a luminance value after addition as an image signal of the nth frame.
