摘要
A smear correction circuit for elimination of smear error within image sensing devices wherein image receiving means receive CCD image data, a determination of a smear scaling factor for smear estimation is made, the smear scaling factor being determined by a ratio of smear error per given level of illumination. The smear estimation means provide for the determining of a value for smear estimation on a per line basis. Adjustment of the image data is made corresponding to the smear estimation and dark level correction values prior applying the adjusted data to gain adjustment circuitry.
