Apple patents method to fix color fringes in high-resolution displays

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, wherein the image frame is divided into a plurality of adjustable regions having respective resolutions of the plurality of resolutions; and image processing circuitry, configured to generate chromatic aberration corrected image data, comprising: warp circuitry configured to generate respective warped image data for each of the plurality of adjustable regions using corresponding portion of a first color component of input image data of the image frame based on a first distortion of the first color component; and chromatic aberration correction (CAC) circuitry configured to apply spatial resampling to the corresponding portion of a second color component of the input image data to compensate a second distortion of the second color component based on a first difference between the second distortion and the first distortion, wherein the first difference between the second distortion and the first distortion comprises a first offset along a first direction on the electronic display and a second offset along a second direction on the electronic display, wherein the chromatic aberration correction circuitry comprises a separable warp architecture comprising: a first mapping circuit configured to apply spatial resampling to the corresponding portion of the second color component of the input image data based on the first offset; and a second mapping circuit configured to apply spatial resampling to the corresponding portion of the second color component of the input image data based on the second offset, wherein the first mapping circuit operates separately from the second mapping circuit.
