Claim 0:
1. An electronic device comprising:
an electronic display comprising a plurality of pixels and configured to display an image frame at a plurality of resolutions based on compensated image data, wherein the image frame is divided into a plurality of adjustable regions having respective resolutions of the plurality of resolutions, wherein the plurality of resolutions comprises at least two different resolutions; and
image processing circuitry configured to generate the compensated image data by applying gains to input image data to compensate for burn-in related aging of the plurality of pixels, wherein generating the compensated image data comprises:
obtaining boundary data indicative of locations of boundaries between the plurality of adjustable regions;
obtaining a gain map of gain values in a constant resolution;
dynamically resampling the gain map to generate a multi-resolution gain map of resampled gain values for the image frame based on the boundary data, wherein dynamically resampling the gain map comprises resampling a first portion of the gain map corresponding to a first adjustable region of the plurality of adjustable regions by a first factor and resampling a second portion of the gain map corresponding to a second adjustable region of the plurality of adjustable regions by a second factor; and
applying the resampled gain values to the input image data.
