Abstract
For color correction in an image sensor, an image sensor processing block generates a plurality of color correction parameters corresponding to a plurality of selected pixels of the image sensor for defining a plurality of areas of a sample image. In addition, a color correction value calculation block generates a respective color correction value corresponding to a given pixel from bilinear interpolation of a respective subset of the color correction parameters corresponding to a respective one of the areas including a respective location of the given pixel.
