| 主权项 | 1. An image processor, comprising: 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, wherein the random number sequence generation section inverts the polarity of the random number sequence once every two frames without changing the absolute values thereof. | ||
