Abstract
Examples described herein include a graphics processing apparatus that includes a memory device and a display engine coupled to the memory device. The display engine is configured to apply dither on a region of an image and modify a first pixel of an image stored in the memory based on pseudo-random noise to reduce color banding impressions. In some examples, the pseudo-random noise is based on one or more of: local brightness estimation and one or more prior noise levels. In some examples, the display engine is to determine the local brightness estimation based on an average brightness of a pixel region surrounding the first pixel and the first pixel. In some examples, the display engine is configured to bound the pseudo-random noise based on a noise applied to a pixel in a same position as that of the first pixel in a prior frame within a same scene.
