Abstract
A processor or other circuitry may obtain emissive element strength information for an array of emissive elements of an electronic display. The processor or other circuitry may reconstruct backlight information at multiple locations within the electronic display. The processor or other circuitry also compensates display of image data based at least in part on the reconstructed backlight information.
Claims20
A method, comprising:
- at a processor, obtaining emissive element strength information for an array of emissive elements of an electronic display;
- reconstructing, using the processor, backlight information at a plurality of locations within the electronic display;
- and
- compensating display of image data based at least in part on the reconstructed backlight information.
1 more element
A system comprising:
- statistics circuitry configured to generate statistics relating to display of image data on an electronic display, wherein the statistics comprise strength information for a plurality of emissive elements configured to backlight the electronic display;
- backlight reconstruction and compensation system configured to receive the image data and the strength information, wherein the backlight reconstruction and compensation system comprises:
- backlight reconstruction circuitry configured to receive the strength information and reconstruct luminance levels of the backlight at a plurality of locations in the electronic display;
- and
- backlight compensation circuitry configured to:
- receive the reconstructed luminance levels from the backlight reconstruction circuitry and the image data;
- and
- adjust the image data to compensate for backlight variance at the plurality of locations based at least in part on the reconstructed luminance levels.
