This paper proposes the power constrained contrast enhancement algorithm for OLED display based on the multi-mapping functions for improving the local contrast of the input image. The proposed method divides the input image into several blocks. Then, it calculates the multi-mapping functions corresponding to each block using convex optimization process between the image quality and power consumption. Using the multi-mapping function, the proposed method adjusts the mapping function and… CONTINUE READING
