A method and apparatus for adjusting the pixel colors of a digital image. After the raw image data from the digital image is white-balanced, the white-balanced image data is conveyed to a color correction module as color vectors in a color space for color adjustment using a color correction matrix. The color adjustment is based on a plurality of base matrices, wherein at least two of the base matrices are different from each other, and a plurality of weighting values, one weighting value for each base matrix. With the base matrices and the weighting values, a correction matrix can be derived from the sum of the base matrices weighted with said weighting values and applied to at least some of the color vectors.
A method for adjusting one or more colors of an image, wherein the colors are representable by a plurality of color vectors, said method comprising:
An image processing module, comprising:
