The invention discloses a color correction method with high fault tolerance for the chromaticity estimation result of an automatic white balance module light source in a color digital camera. The invention calculates the spectral transformation relationship between the spectral sensitivity function of the camera and the CIE1931 color matching function, The original RGB response signal of the camera is transformed into CIE1931 XYZ space which is independent of the equipment, and the corresponding color response value after color adaptation under the reference light source is calculated by usingCAT02 color adaptation transformation model, so that the color correction flow which does not depend on the pre-calibration parameters is realized.
