Abstract:
A display device is provided that includes an amount of light emission computation portion that computes an amount of light emission based on a video signal that has a linear characteristic, an amount of light emission parameter computation portion that, based on the computed amount of light emission, computes an amount of light emission parameter that corresponds to the amount of light emission for each of one of one pixel and a group of pixels that includes a plurality of the pixels, an amount of light emission parameter accumulation portion that accumulates the amount of light emission parameters in association with the one of the one pixel and the group of pixels, a peak detection portion that detects a peak value among the accumulated amount of light emission parameters that correspond to all of the one of the one pixel and the group of pixels, a coefficient computation portion that, based on the detected peak value, computes a coefficient that adjusts a luminance, and a coefficient multiplying portion that multiplies the video signal by the computed coefficient and outputs the multiplied video signal.
