Abstract
Systems and methods are provided for collecting image statistics using a pixel mask. In one example, statistics collection logic of an image signal processor may include a pixel weighting mask and accumulation logic. The pixel weighting mask may receive a first representation of a pixel that includes a luma and chroma representation of the pixel. The pixel weighting mask may output a pixel weighting using first and second chroma components of the luma and chroma representation of the pixel. The accumulation logic may receive the first or a second representation of the pixel and the pixel weighting value. Using these, the accumulation logic may weight the second representation of the pixel or the first representation of the pixel using the pixel weighting value to obtain a weighted pixel value, adding the weighted pixel value to a statistics count.
