초록
We describe the contrast enhancement of images using an APL(Average Picture Level) in an AC-PDP. A CEC(Contrast Enhancement Curve) determined by the APL was applied to enhance the contrast of images depending on the dominant gray levels. The most effective advantage of the proposed method is that it is easier to adjust the dynamic ranges to be enhanced with good quality and implement in a hardware system. The simulation result shows that the proposed method enhanced the contrast of given images significantly and kept the original brightness except the specific area of them compared to the HE(Histogram Equalization).
