| 主权项 | 1. A display apparatus that displays an image by causing a light emitting device to emit light, the display apparatus comprising: a detection unit configured to detect flicker information that indicates a likelihood of occurrence of a flicker based on input image information, the flicker information calculated based on an average picture level (APL) value by averaging gradation numbers based on the input image information for each of a plurality of regions corresponding to blocks into which an image display region is divided; and a control unit configured to control both of a light emission luminance and a duty ratio of a light emission time of the light emitting device according to the flicker information detected by the detection unit. | ||
