Abstract:
A power consumption controller includes (a) a power consumption calculation section which sequentially calculates the power consumption level of a self-luminous display device based on a video signal input from the beginning of each frame up to the time of calculation, (b) a power consumption status determination section which determines whether the calculated power consumption level exceeds a reference value for comparison by constantly comparing the two levels. If this is the case, the same section detects the timing at which the power consumption exceeds the reference value for comparison and (c) a peak brightness control section which controls the peak brightness of the self-luminous display device if the power consumption level exceeds the reference value for comparison based on the detected timing.
Abstract:
A self-luminous display apparatus, a peak luminance adjustment apparatus is disclosed wherein power to be consumed by a self-luminous display panel is compulsorily suppressed to a level within a prescribed range and consequently the life of a battery is maintained. A mean gradation value calculation section calculates a mean gradation value of a video signal inputted within a period of one frame. A power consumption calculation section determines a standard peak luminance corresponding to the calculated mean gradation value and calculates a power consumption amount to be consumed based on the standard peak luminance and the calculated mean gradation value. A peak luminance adjustment section adjusts the standard peak luminance so that a total value of the power consumption to be consumed within a fixed period of time may not exceed a preset power amount.
