    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: 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 of the disclosure are directed to rotation of the graphics layer in video application. In accordance with one aspect, the apparatus includes a memory configured for storing a video layer in a compressed format and the graphics layer in an uncompressed format; and a display processing unit (DPU) coupled to the memory, the DPU configured for converting the graphics layer into an original compressed graphics layer, and for performing a graphics rotation on the original compressed graphics layer for generating a rotated compressed graphics layer. And, the method for rotation of a graphics layer includes converting the graphics layer into an original compressed graphics layer using a processing engine; and generating a rotated compressed graphics layer by using the processing engine to perform a graphics rotation on the original compressed graphics layer.
