Abstract:
Provided is a display device including a panel (158) in which a plurality of pixels that emit light in response to a video signal are arranged, a light emission amount calculation unit (164) that acquires a light emission amount on a plurality of positions of the panel (158) based on a video signal supplied to the panel (158), a storage unit (150) that accumulates data related to the light emission amount accumulated based on a video signal of a plurality of frames, a high-brightness gamma adjustment block (172b) that reduces brightness of a high brightness side of the video signal supplied to the panel (158) based on the data related to the light emission amount accumulated in storage unit (150), and a low-gradation gamma adjustment block (172c) that reduces brightness of a low brightness side of the video signal in conjunction with a reduction in brightness of the high brightness side.
