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

Abstract: An electronic device may include an electronic display to display an image based on processed image data. The electronic device may also include image processing circuitry to generate the processed image data. The image processing circuitry may receive input image data corresponding to an image in a first perspective and warp the input image data from the first perspective to a second perspective, generating warped image data. Additionally, the image processing circuitry may determine one or more occluded regions in the second perspective and determine fill-data corresponding to the occluded regions. The processed image data may be generated by combining the warped image data and the fill-data.

Abstract: An electronic device may include an electronic display to display an image based on processed image data. The electronic device may also include image processing circuitry to determine a hierarchical grid having multiple grid points divided into grid partitions. A first set of grid points associated with a first set of grid partitions may include a first set of mappings to corresponding coordinates of input image data in a source frame. The image processing circuitry may also interpolate between the first set of grid points to determine a second set of grid points of having a second set of mappings to corresponding coordinates of the input image data based on the first set of mappings. The image processing circuitry may also generate the processed image data by applying the first set of mappings and the second set of mappings to the input image data.

Abstract: An electronic device includes an electronic display configured to present an image based on image data and a display pipeline having image processing circuitry to process the image data for display on the electronic display by receiving the image data, referencing a lookup table (LUT) to determine output values based on a plurality of input value sets associated with the image data, the LUT including entries respectively mapping an output value to a defined input value set, determining whether an input value set of the plurality of input value sets is represented by the entries of the LUT, performing curvature interpolation to determine an interpolated output value associated with the input value set in response to determining the input value set of the image data is not represented by the entries of the LUT, and applying the interpolated output value to the input value set to generate updated image data.

Abstract: In various implementations, a method includes obtaining a first frame that is characterized by a first resolution associated with a first memory allocation. In some implementations, the method includes down-converting the first frame from the first resolution to a second resolution that is lower than the first resolution initially defining the first frame in order to produce a reference frame. In some implementations, the second resolution is associated with a second memory allocation that is less than a target memory allocation derived from the first memory allocation. In some implementations, the method includes storing the reference frame in a non-transitory memory. In some implementations, the method includes obtaining a second frame that is characterized by the first resolution. In some implementations, the method includes performing an error correction operation on the second frame based on the reference frame stored in the non-transitory memory.

Abstract: An electronic device may include an electronic display to display an image based on compensated image data in a panel space. The electronic device may also include image processing circuitry to generate the compensated image data. Further, generating the compensated image data may include determining a first inverse mapping of a pixel grid from the panel space to a rendering space and determining a forward mapping of the pixel grid from the rendering space to the panel space based on the first inverse mapping. The forward mapping may include corrections for multiple different warp operations stacked in a single warp operation. Additionally, the image processing circuitry may apply the forward mapping to input image data to generate the compensated image data.
