Abstract
An image processing device that generates a second output image signal output to a second liquid crystal panel that is disposed to be superposed on a first liquid crystal panel, includes: a first corrector that generates a gamma correction signal in which a gradation value of an input image signal is corrected; a detector that receives the gamma correction signal and detects an image region brighter than surroundings as a first high-frequency portion from the gamma correction signal; and a second corrector that receives the gamma correction signal and a detection result of the detector and performs correction to decrease the gradation value of the first high-frequency portion in the gamma correction signal. The second output image signal is generated based on the gamma correction signal corrected by the second corrector.
