Abstract
A method for correcting pixel digital response of a charge coupled device (CCD) is provided. First, fetch black reference values and white reference values of each pixel of the CCD. Then, calculate gain values according to the black and white reference values. Further, generate and store a correction table according to the black reference values and the gain values. Finally, adjust and get a correction value from a real response of the CCD according to the correction table. Therefore, the CCD response is corrected and improved.
