Abstract

A video processing circuit includes a detecting unit that detects a set of a first pixel and a second pixel adjacent to the first pixel, which is a set of pixels in which a difference between application voltages to the first pixel and the second pixel which are indicated by an input video signal is greater than or equal to a threshold; an acquisition unit that acquires information which specifies a plurality of regions of voltage-brightness characteristics which are voltage-brightness characteristics of the pixel group and in which a voltage region is separated into the plurality of regions in accordance with a slope of the voltage-brightness characteristics; and a replacing unit that replaces the application voltage to the first pixel with a voltage which is in a region other than a first region and is close to a second region.
