Abstract
A video processing circuit detects a risk boundary, which a portion of the boundary between a dark pixel and a bright pixel in an image represented by a video signal Vid-in, and is determined by a tilt azimuth of liquid crystal molecules, from the boundary, and corrects a video signal corresponding to at least one of the dark pixel and the bright pixel which is contiguous to the detected risk boundary in at least one field of a plurality of fields constituting one frame such that a period in which the risk boundary is present in one frame period is shortened.
