1. A display system, comprising:
a display panel; and
a display stream compression (DSC) decoder to:
receive actual image data for each pixel of an image to be displayed on the display panel;
filter the actual image data to obtain filtered image data for each pixel;
determine a difference between the actual image data and the filtered image data for each pixel; and
if an absolute value of the difference between the actual image data and the filtered image data for each pixel is above a threshold, add a weight value to the actual image data of the pixel if the actual image data is greater than the filtered image data, or subtract the weight value from the actual image data of the pixel if the actual image data is less than the filtered image data.
