Abstract
Image processing circuitry may include burn-in compensation circuitry that receives image data indicative of luminance outputs for display pixels of an electronic display and compensates the image data for burn-in related aging associated with the display pixels, generating compensated image data. Moreover, compensating the image data may include applying gains based on estimated amounts of aging associated with the display pixels and estimated amounts of current to be delivered to the display pixels. The image processing circuitry may also include burn-in statistics circuitry that tracks the estimated amounts of aging based on the compensated image data.
