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: Aspects presented herein relate to methods and devices for display processing including an apparatus, e.g., a DPU. The apparatus may obtain an indication of associated with a plurality of pixels corresponding to a plurality of color channels. The apparatus may also divide each of the plurality of color channels. The apparatus may also select at least one first color channel of the plurality of divided color channels. Further, the apparatus may scale each of the pixels associated with the at least one first color channel. The apparatus may also blend, based on each of the plurality of scaled pixels, all of the plurality of pixels associated with the at least one first color channel. The apparatus may also transmit, based on all of the plurality of blended pixels, an indication of the plurality of pixels associated with the at least one first color channel.

Abstract: Aspects presented herein relate to methods and devices for display processing including an apparatus, e.g., a DPU. The apparatus may receive each of a plurality of frames in a scene. The apparatus may also convert a data format for each of the plurality of frames to one or more DSC bit streams for each of the plurality of frames. Further, the apparatus may store the one or more DSC bit streams for each of the plurality of frames in a first memory or a first cache. The apparatus may also read the one or more DSC bit streams for each of the plurality of frames from the first memory or the first cache. The apparatus may also transmit, to a display panel, the one or more DSC bit streams for each of the plurality of frames.

Abstract: Aspects presented herein relate to methods and devices for graphics processing including an apparatus, e.g., a GPU or a DPU. The apparatus may obtain at least one image in a set of images corresponding to a scene associated with the graphics processing. The apparatus may also perform a non-linear foveated compression process on the at least one image, where the non-linear foveated compression process corresponds to a continuous non-linear compression for a portion of the at least one image. The apparatus may also transmit the at least one image after the non-linear foveated compression process, such that the transmitted at least one image corresponds to at least one compressed image.

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: 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.
