Abstract:
1. A video signal processing apparatus comprising: a contrast compensation unit for compensating contrast of a video signal; an edge compensation unit for compensating an edge portion of the video signal; and a control circuit for controlling the contrast compensation unit and the edge compensation unit on the basis of luminance information of the video signal, wherein said control circuit determines a gradation range in which image quality is compensated on the basis of the luminance information of the video signal, and controls said contrast compensation unit so that the contrast of the video signal belonging to the luminance range thus determined is made higher than that of the video signal belonging to another luminance range, and also controls said edge compensation unit so that an edge compensation quantity for the video signal belonging to the luminance range thus determined is made smaller than that in the video signal belonging to another gradation range.
