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.

Claim (Index 2):
The electronic device of  claim 1 , wherein, to determine the first pixel statistics, the pixel contrast control processing circuitry is programmed to:\n determine an active region in the current image frame that excludes portions of the current image frame which comprise subtitles, a picture-in-picture area, a constant color, or a combination thereof; determine a first set of local windows that completely enclose the active region; determine a plurality of luma values each associated with one image pixel in the current image frame based at least in part on the received image data; determine a first global luma histogram based at least in part on luma values associated with each image pixel in the active region; and determine a plurality of local luma histograms each associated with a first corresponding local window of the first set of local windows based at least in part on luma values associated with each image pixel in the first corresponding local window.
