Abstract

An electronic device may include a display pipeline to be coupled between an image data source and a display panel. The display pipeline may include pixel contrast control processing circuitry programmed to determine pixel statistics indicative of an image frame based at least in part on image data that indicates an initial target luminance of a corresponding display pixel implemented on the display panel. The pixel contrast control circuitry may also apply a set of local tone maps to determine modified image data that indicates a modified target luminance. The display pipeline may also include a pixel contrast control controller coupled to the pixel contrast control processing circuitry. The pixel contrast control controller may be programmed to execute firmware instructions to determine local tone maps to be applied during the next image frame based at least in part on the pixels statistics determined by the pixel contrast control processing circuitry.
