Abstract:
1. An apparatus, comprising: a detector circuit configured to detect whether a single-color pixel is located in a flat area or a non-flat area of a digital image containing the single-color pixel, and to detect whether the single color pixel is defective based on whether the single-color pixel is located in a flat area or a non-flat area and based on a noise curve associated with the single-color pixel; and a corrector circuit configured, if the single-color pixel is detected to be defective, to correct the defective single-color pixel with a flat-type correction if the single-color pixel is detected to be in a flat area and correcting the single-color pixel with a non-flat-type correction if the single-color pixel is detected to be in a non-flat area.
