Patent ID: 7990437

Claim:
An apparatus for color correction in an image sensor, comprising: an image sensor processing block for generating a plurality of first color correction parameters corresponding to a plurality of selected pixels of the image sensor for defining a plurality of areas of a sample image, wherein the first color correction parameters correspond to when a zoom magnification is a predetermined value; and wherein each color correction parameter represents a difference between at least two color components for a respective one of the selected pixels and wherein the image sensor processing block determines and generates modified color correction parameters using a value of the zoom magnification and the first color correction parameters, when the zoom magnification is not the predetermined value; and a color correction value calculation block for generating a respective color correction value corresponding to a given pixel from interpolation of a respective subset of the first color correction parameters corresponding to a respective one of the areas including a respective location of the given pixel, when said zoom magnification is the predetermined value, and wherein the color correction value calculation block generates the respective color correction value corresponding to the given pixel from interpolation of a respective subset of the modified color correction parameters corresponding to the respective one of the areas including the respective location of the given pixel, when said zoom magnification is not the predetermined value.
