Abstract
Embodiments of the present invention relate in general to systems and methods for dynamically correcting color cross-talk and related color distortion in an image sensor. More specifically, but not by way of limitation, certain embodiments of the present invention relate to correcting pixel outputs from a pixel array in an image sensor at the Bayer domain for color cross-talk and/or green disparity using hyperbolically varying correction functions to dynamically derive color cross-talk correction factors using pixel location on the pixel array, a selected pixel output and related outputs from neighboring pixels on the image sensor prior to or synchronous with color interpolation.
