Abstract
A rearranger circuit rearranges data elements of each raw image of a plurality of raw images according to a plurality of raw color channel arrays. The data elements of each raw image are input to the rearranger circuit according to instances of a pattern of color channels of a color filter array (CFA). The data elements specify values of the color channels in the instances of the pattern, and each raw color channel array has the data elements of one color channel of the color channels in the instances of the pattern. The rearranger circuit can be used in neural network training or in generating raw color channel arrays for performing neural network inference.
