A method for correcting pixel information of color pixels on a color filter array of an image sensor includes: establishing an M×M distance factor table, selecting M×M pixels of the color filter array, calculating a red/green/blue-color contribution from the red/green/blue pixels to a target pixel in the selected M×M pixels, calculating a red/blue/green-color pixel performance of the target pixel, calculating a red/blue/green-color correcting factor, obtaining a corrected pixel information of each of the red/green/blue pixels, by applying the red/green/blue-color correcting factor to the measured pixel information of each of the red/green/blue pixels.
