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: Image processing can include producing a first mosaic of an image with a first spectral pattern, assigning a context to the first mosaic, classifying the first mosaic based on the assigned context, and producing a second mosaic of the image based on the classifying. The second mosaic can have a second spectral pattern different than the first spectral pattern.

Abstract: Systems and techniques are provided for generating an HDR image. An example method can include obtaining a first image and a second image that has an exposure that is greater than an exposure of the first image; setting pixels of the first image that are below a minimum threshold to a minimum value and pixels of the second image that are above a maximum threshold to a maximum value; retrieving, from memory, a compressed version of the first image with the pixels set to the minimum value and a compressed version of the second image with the pixels set to the maximum value; generating a first decompressed image including the first image with the pixels set to the minimum value and a second decompressed image including the second image with the pixels set to the maximum value; and generating an HDR image based on the first and second decompressed images.
