IMAGE PROCESSOR AND IMAGE PROCESSING METHOD

摘要

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.

1. An image processor for processing an image signal and outputting the image signal to a liquid crystal panel, comprising:
a random number sequence generation section configured to generate a random number sequence; a random-number-superimposed luminance variable generation section configured 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 configured 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 changes a timing of inverting polarity of the random number sequence without changing absolute values of the random number sequence, thereby to generate a state such that a polarity of a starting random number and a polarity of a polarity inversion signal to reverse polarity of liquid crystal are different.
