Abstract: Disclosed herein is an image processor including: a random number sequence generation section adapted to generate a random number sequence; a random number-superimposed luminance variable generation section adapted to generate a random number-superimposed luminance variable by superimposing the random number sequence on a luminance variable; and a random number-superimposed image signal generation section adapted to generate a random number-superimposed image signal by superimposing the random number-superimposed luminance variable on an image signal.

Abstract: An image processing apparatus includes an image display unit and a luminance control unit. The image display unit includes pixels arranged in a matrix, each of which is formed of a first sub-pixel, a second sub-pixel, a third sub-pixel, and a fourth sub-pixel, and performs image display. The luminance control unit adjusts a ratio between a generation amount of first luminance generated by the first sub-pixel, the second sub-pixel, and the third sub-pixel and a generation amount of second luminance generated by the fourth sub-pixel. Over all input tones, the luminance control unit makes the generation amount of the second luminance lower than the generation amount of the first luminance and generates the second luminance so that a function representing a luminance value of the second luminance is continuous.
