1. An image signal processor comprising:

  • statistics collection logic comprising;

    a pixel weighting mask configured to;

    receive a first representation of a pixel, wherein the first representation of the pixel comprises a luma and chroma representation of the pixel; and

    output a pixel weighting value based at least partly on first and second chroma components of the luma and chroma representation of the pixel; and

    accumulation logic configured to;

    receive a second representation of the pixel or the first representation of the pixel;

    receive the pixel weighting value;

    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; and

    add the weighted pixel value to a statistics count.
