Abstract
In power saving luminance control that the maximum luminance of one field is varied according to an average luminance level of an image, the luminance of a subfield at the minimum luminance level is fixed to a certain value without depending upon the variation of the maximum luminance of one field. Hereby, even if luminance control that the maximum luminance of one field is enhanced in an image the average luminance level of which is low is made, a gradation characteristic in a low luminance region is improved.
