Assignee: APPLE INC.
Field: Audio-visual technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 10:
11. Image processing circuitry comprising:
burn-in statistics collection circuitry configured to maintain a burn-in history map indicative of an estimated amount of cumulative burn-in of a plurality of pixels of an electronic display;
map generation circuitry configured to generate a gain map based on the burn-in history map, wherein the gain map comprises a constant resolution format; and
burn-in compensation circuitry configured to:
dynamically resample the gain map from the constant resolution format to a multi-resolution format comprising at least two different resolutions to generate a multi-resolution gain map for a single image frame; and
compensate input image data having in multi-resolution format for the estimated amount of cumulative burn-in based on the multi-resolution gain map.
