Abstract
A color correction method is applied to an image correction apparatus having an image sensor, and includes searching a color deviation area within a detection image, analyzing the detection image to estimate a correction color value of the color deviation area, and calibrating the color deviation area by the correction color value to generate a calibrated detection image without color deviation.
