Abstract	The ability of the color reproduction is the main criterion which is used for assessing the image quality in display devices. The skin color becomes the primary research object because it occupies relatively large area in the video signals. Therefore, a method of dynamic skin color correction is proposed in this paper. In the proposed method, the skin color region which is required to adjust in the input image is shifted dynamically toward the characteristic skin color region so that the corrected skin color becomes more natural. Based on the dynamic skin color correction method, the simple model is proposed for the convenience of hardware implementation in this paper. Furthermore, the real-time dynamic skin color correction circuit based on the simple model is implemented and validated in a 42-inch AC PDP. The experiment results in the 42-inch AC PDP show that the skin color corrected with the proposed method in the output image becomes more natural and more vivid and accords with that perceived by people much more. Consequently, the image quality in AC PDP can be improved effectively.
