Abstract

An image processing circuit includes a memory, a gamma converter which converts a first image data signal of a frame to a current image data signal thereof corresponding to first or second gamma types based on a spatial distribution pattern, a compression circuit which separates the current image data signal into first and second gamma signals corresponding to the first and second gamma types and compresses the first and second gamma signals to first and second compression gamma signals to store the first and second compression gamma signals, a decompression circuit which output a previous image data signal of a previous frame by decompressing the first and second compression gamma signals and combines first and second decompression gamma signals, and a gamma correction circuit which performs a gamma adjustment based on current and previous image data signals to output a second image data signal.
