Plasma Display Panel (PDP) is required to be both the determination of white point and the inverse gamma correction since non-balanced RGB cell and linear-property of PDP. However, these two methods cause degradation of color level representation and false contour in the dark region on PDP. In this paper, we implement real time image processor of the proposed error diffusion algorithm and unsharp-masking operation to protect the blurring image caused by the error diffusion. Based on these results, we achieved drastic improvements of color level representation and elimination of false contour.
