The gradation representation capability is automatically controlled according to gradation regions and properties (moving or still image) of an input video signal. In a gradation representation pattern information storage circuit is stored a plurality of pieces of gradation representation pattern information which are different in the number of repetition unit frames for gradation representation according to a plurality of degradation regions. One piece of gradation representation pattern information stored in the gradation representation pattern information storage circuit is selected according to a gradation region detected from an input video signal. Gradation representation data of the frame rate corresponding to the selected gradation representation pattern information is output.
