Abstract

A system, method, and computer-readable medium are disclosed for reducing halo artifacts of static images on a computer display. A multimedia stream is received that includes graphical images which are moving and static images as displayed on the computer display. A determination is performed if a graphical image in the multimedia stream is a static image. Additional LED zones of LEDs are turned on to provide backlighting to a computer display panel. A diming algorithm is enabled to adjust LEDs to reduce halo artifacts in the static image. Luminance correction is performed at the pixel level for the static image.
