  • Patent number: 9066056
    Abstract: An electronic device may have a camera module. The camera module may capture images. The electronic device may include image processing circuitry that color corrects the images. The image processing circuitry may desaturate the images globally and/or spatially based on global and/or spatial noise levels of the image. The image processing circuitry may desaturate the images substantially without changing the hue of the images. The image processing circuitry may generate a color correction matrix with constant hue in real time and may color correct images in real time as the images are captured by the camera module.
