Abstract
A look-up table unit converts input video signal data of N bits into (M+F+D) bit data by performing inverse gamma correction and linear interpolation. An error diffusion unit converts the (M+F+D) bit data into (M+F) bit data by error diffusion processing. A frame rate control unit converts the (M+F) bit data into M bit data by frame rate control. A sub-frame data conversion unit, by using a gradation driving table and the M bit data, generates sub-frame data in which all sub-frames include a step-bit pulse respectively, and in which the number of sub-frames to be in a drive state every time the drive gradation increases by one, is increased one by one.
