Abstract:
A video processing circuit, includes: a boundary detection section adapted to detect a boundary between a first pixel having an applied voltage, which is designated by the video signal input and is lower than a first voltage, and a second pixel having an applied voltage, which is designated by the video signal input and is one of equal to and higher than a second voltage higher than the first voltage, in a present frame and in a previous frame, which is one frame earlier than the present frame, respectively; and a correction section adapted to correct the video signal adapted to designate the applied voltages to the liquid crystal elements corresponding to the first pixel and the second pixel abutting on a moving section in the boundary of the present frame moving one pixel from the boundary in the previous frame so as to reduce a lateral electrical field caused by the first pixel and the second pixel.
