Abstract:
1. A self-luminous display apparatus capable of variably controlling a peak luminance of a self-luminous panel in a unit of one frame, comprising: a mean gradation value calculation section that calculates within a period of one frame unit mean gradation values of a video signal respectively in units of one frame; a power consumption calculation section that determines standard peak luminances corresponding to the calculated mean gradation values and that calculates power consumption amounts consumed respectively based on the standard peak luminances and the calculated mean gradation values; and a peak luminance adjustment section that adjusts the standard peak luminance based on the power consumption amounts calculated for at least two frames so that a total power consumption within a fixed period does not exceed a preset power amount, wherein the power consumption calculation section calculates the power consumption amounts by multiplying the mean gradation value, a peak luminance magnification, and a reference peak luminance.
