Abstract
The present invention provides a defect compensating method of color image, which is suitable for a color image sensor having plural pixels. The method includes the steps of: presetting first and second thresholds, and defining a matrix range; when the difference between a pixel and any one of two adjacent pixels having the same color is larger than the first threshold, determining this pixel as a peak pixel, otherwise determining this pixel as a normal pixel; when the difference between any one of two pixels neighbored to the peak pixel and any one of two adjacent pixels having the same color is smaller than the second threshold, and all pixels in the matrix range centered at the peak pixel are normal pixels, determining this pixel as a defective pixel; and correcting the color value of the defective pixel.
