Abstract:
1. A self-luminous display apparatus capable of varying a peak luminance of a display panel in a unit of at least one frame, comprising: a mean gradation value calculation section configured to calculate a mean gradation value of an input video signal in a unit of at least one frame; a specific condition detection section configured to detect, by comparing the mean gradation value of the current frame and mean gradation values averaged over a period of several frames, whether said input video signal satisfies a specific condition or not; and a light emission condition control section configured to perform dropping control of said peak luminance of said display panel in a unit of a frame based on at least the detection of said specific condition, wherein said peak luminance is continuously decreased by a predetermined speed while said specific condition is being satisfied, and wherein said predetermined speed is a constant speed being independent of said input video signal.
