Abstract:
1. A method for compressing color imagery from a single sensor of interleaved color primaries comprising: retrieving, from a memory buffer of an imaging device, an image plane including a plurality of pixel values of spatially-interleaved color primaries; separating the spatially-interleaved color primaries into a plurality of independent color channels comprising at least a first independent color channel, a second independent color channel, and a third independent color channel, the first independent color channel and the second independent color channel representing the same color in different color planes, and the third independent color channel representing a different color than the first independent color channel and the second independent color channel; encoding the difference between each pixel value in a first set of pixel values associated with the first independent color channel and a corresponding pixel value in a second set of pixel values associated with the second independent color channel into a compressed form; encoding the sum of each pixel value in the first set of pixel values associated with the first independent color channel and the corresponding pixel value in the second set of pixel values associated with the second independent color channel into a compressed form; multiplying a third set of pixel values associated with the third independent color channel by a factor of 2; encoding the difference between each pixel value in the multiplied third set of pixel values and a corresponding sum of a first pixel value in the first set of pixel values and a second pixel value in the second set of pixel values into a compressed form; and storing each of the compressed forms in a memory.
