1. A computer-implemented method for color correction, comprising:
- color correcting a noise evaluation image using a plurality of color correction parameters;
determining a noise amplification metric by comparing the corrected noise evaluation image with the pre-correction noise evaluation image, wherein determining the noise amplification metric further comprises determining a ratio between a first variance of a color space component for the pre-corrected noise evaluation image and a second variance of the color space component for the post-corrected noise evaluation image; and
adjusting the plurality of color correction parameters based on the noise amplification metric.
