| Abstract: | CCD sensor with frame transfer structure is extensively used for its advanced performances. But there is smear problem introduced by frame transfer procedure. Three structures of area sensor and their features are introduced. The procedure of frame transfer CCD sensor is emphasized. The cause of the frame transfer smear is analyzed, and the method of smear restoration is proposed. Some examples are put forward and good results of smear restoration are shown. |
