1. A system, comprising one or more integrated circuits, wherein the one or more integrated circuits are configured to: receive a video image; calculate a brightness metric associated with the video image; determine an intensity setting of a light source, which illuminates a display that is configured to display the video image, and scale brightness values of the video image based on the brightness metric; identify a region in the video image in which the scaling of the brightness values results in a visual artifact associated with reduced contrast; and reduce the scaling of the brightness values in the region to, at least partially, restore the contrast, thereby reducing the visual artifact.
