This paper studies power efficient image processing method for power consuming display device. Power is consumed by display device and its portion is large. We developed unsharp masking under power-constrained condition. For this system, we assume an image is dark with low contrast. The presented unsharp masking adopts high pass filter, Butterworth filter, and histogram equalization. Simulation results compare visual performance in several power-constrained conditions with factors of n. Results show that the proposed method achieved good visual quality and significant power saving performance.
