ABSTRACT:
A nonlinearly processed (gamma-corrected) video signal is subjected to three-dimensional signal level correction using three-dimensional correction values and corresponding to a position in a horizontal direction and a vertical direction of a pixel on a display screen of an image display unit and the signal level of the pixel data. Thereby, accurate gamma correction is made possible, and horizontal and vertical area information (grid block) can be disposed in an optimum positional relation according to resolution of the screen.
