Abstract: In a computing device having a pipeline of image processing components, DCVS bandwidth voting may be based on a feedforward compression ratio determined by the first image processing component in the pipeline. The DCVS bandwidth voting may be based on the result of a comparison of change in the feedforward compression ratio with a threshold. Transaction initiator components in the pipeline may select their votes for bandwidth from among a feedforward compression ratio-based value and one or more other values, based on the result of the comparison with the threshold. DCVS parameters may be selected based on bandwidth votes received from transaction initiator components.

Abstract: This disclosure provides systems, methods, and devices for image signal processing that support compression of image data from image sensors with different color filter array (CFA) configurations. In a first aspect, a method of image processing includes receiving, by a processor, first image data from a first image sensor having a first color filter configuration, the first image data comprising a plurality of values organized according to the first color filter; determining, by the processor, second image data by re-arranging the plurality of values of the first image data; determining, by the processor, third image data by compressing the second image data; and storing, by the processor, the third image data into memory. Other aspects and features are also claimed and described.

Abstract: Embodiments include methods for image compression and decompression. A sending computing device may determine a type of packing used for a chunk of image data, generate metadata describing the type of packing used for the chunk of image data, pack the chunk of image data according to the determined type of packing, and send the packed chunk of image data and the metadata to a second computing device. A receiving computing device may decode the metadata describing the type of packing used for the chunk of image data, determine the type of packing used for the chunk of image data based on the decoded metadata, and unpack the chunk of image data according to the determined type of packing used for the chunk of image data.
