Abstract
An image processing device includes a correction section adapted to perform a correction process of data of low (N−M) bits (N and M are integers fulfilling N>M) of a gray level value represented by input video data in a case in which the data of the low (N−M) bits coincides with a predetermined bit sequence, and a modulation section adapted to set data on which the correction process has been performed as target data with respect to the pixel having the data of the low (N−M) bits coinciding with the predetermined bit sequence, and perform a modulation process of modulating at least a part of data of high M bits of the target data using a bit sequence defined in accordance with the data of the low (N−M) bits in a plurality of unit periods.
