Title:
CONSUMED POWER CONTROL DEVICE, IMAGE PROCESSING DEVICE, SELF-EMITTING DISPLAY DEVICE, ELECTRONIC DEVICE, CONSUMED POWER CONTROL METHOD, AND COMPUTER PROGRAM
Document Type and Number:
WIPO Patent Application WO/2008/013201
Kind Code:
A1
Abstract:
In the existing consumed power control technique, any conversion treatment is
always applied, on the basis of a consumed power value estimated, to a video signal
(of a gradation value). Proposed is a consumed power control device comprising (a)
a consumed power calculating unit for sequentially calculating, on the basis of
a video signal inputted from the head of each frame to the time point of calculation, an
electric power to be consumed in a self-emitting display device, (b) a consumed power
state deciding unit for always comparing the consumed power value calculated and
a comparison reference value, to decide whether or not the consumed power value
exceeds the comparison reference value, and for detecting the timing of the consumed
power value, in case this power value exceeds the comparison reference value,
and (c) a peak brightness control unit for controlling the peak brightness of
the self-emitting display device on the basis of that detection timing, in case
the consumed power value exceeds the comparison reference value.
