Abstract
An electronic device uses a chromatic aberrations correction (CAC) circuit to correct chromatic aberration on a display panel. An input image is warped based on a first color channel only geometric distortions associated with displaying the input image on the display panel. The CAC circuit applies spatial resampling to other color channels to compensate chromatic aberration based on distortion offsets between the other color channels and the first color channel
Claims20
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 by:
- generating 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
- applying 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.

An electronic device, comprising:
- an electronic display configured to display an input image frame;
- and
- chromatic aberration correction (CAC) circuitry configured to generate chromatic aberration corrected image data of the input image frame by:
- receiving warped input image data of the input image frame, wherein the warped input image are generated from input image data of the input image frame to compensate for a first distortion of a first color component of the input image data;
- and
- applying spatial resampling to a second color component of the input image data to compensate for a second distortion of the second color component based on a first difference between the second distortion and the first distortion.

A method implemented by image processing circuitry, comprising:
- generating, view the image processing circuitry, warped image data for an image frame to be displayed on an electronic display using a first color component of input image data of the image frame based on a first distortion of the first color component;
- and
- applying, view the image processing circuitry, spatial resampling to 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.
