Abstract
A method for compensating image data is adapted for an image sensor. The image sensor has a plurality of photo sensors arranged in an effective region and an optical black region. The method for compensating image data includes a plurality of monochromatic light representative values Scorresponding to pixel positions i is extracted from the photo sensors of the optical black region; a plurality of monochromatic image intensity values Vis extracted from the photo sensors of the effective region; the monochromatic light representative values Sare converted respectively to a plurality of monochromatic compensation values f(S); and compensated image data Vis output after compensating the monochromatic image intensity values Vrespectively based on the pixel positions i and the corresponding monochromatic compensation values f(S). Through the method for compensating image data, a smear effect in the effective region can be compensated effectively.
