Abstract: The present disclosure relates to methods and devices for display processing including an apparatus, e.g., a DPU. The apparatus may receive a plurality of panel measurements for a display panel, each of the plurality of panel measurements associated with a plurality of subpixels in the display panel. The apparatus may also determine, upon receiving the plurality of panel measurements, at least one offset for one or more subpixels of the plurality of subpixels associated with each of the plurality of panel measurements. The apparatus may also store, upon determining the at least one offset for the one or more subpixels, the at least one offset for the one or more subpixels associated with each of the plurality of panel measurements.

Abstract: The present disclosure relates to methods and devices for display processing. The device can receive a first image including a plurality of first pixels. Each of the first pixels can include a first red, green, blue (RGB) color value. The device can also determine an RGB adjustment value based on a lens correction value. Additionally, the device can determine a second RGB color value for each first pixel based on the determined RGB adjustment value. The device can also generate a second image including a plurality of second pixels, where each of the second pixels includes a determined second RGB color value. Moreover, the device can separate at least one of a red color value, green color value, or blue color value of the RGB color value and adjust at least one of a red color value or a blue color value based on the lens correction value.

Abstract: The present disclosure relates to methods and apparatus for display processing. In some aspects, the apparatus can measure at least one panel including one or more panel measurements. The apparatus can also determine at least one correction factor for each of the one or more panel measurements. Further, the apparatus can adjust the at least one correction factor based on each of the one or more panel measurements. In some aspects, the apparatus can compress the at least one correction factor based on each of the one or more panel measurements. Moreover, the apparatus can store the compressed at least one correction factor. In some aspects, the apparatus can decode correction data for at least one frame based on the adjusted at least one correction factor. The apparatus can also store or communicate the decoded correction data for the at least one frame.

Abstract: Techniques are described in which a device is configured to retrieve a metadata buffer for rendering a sub-frame of a set of sub-frames for a frame. A data block of a data buffer is configured to store image data for rendering the sub-frame. In response to determining, based on the metadata buffer for rendering the sub-frame, that the sub-frame includes a color pattern, fixed color value, or combination thereof, the device refrains from retrieving the image data from the data block of the data buffer and determines the image data for rendering the sub-frame based on the metadata buffer.
