ABSTRACT:
An image display apparatus including a plurality of pixels, a drive circuit for outputting drive signals for driving the pixels, and a correction circuit for correcting an input signal corresponding to a predetermined pixel with a correction value to output a corrected input signal to a side of the drive circuit, wherein the apparatus adopts as the correction value a value reflecting drive states of pixels located in the neighborhood of the predetermined pixel, the value being one having received an adjustment according to a nonlinear characteristic between a value of the input signal and a gray-level display of the pixel on the basis of the value of the input signal corresponding to the predetermined pixel.
