ABSTRACT:
A charge coupled device having a CCIR/EIA mode conversion function includes: a plurality of VCCD regions formed in the direction of row, the VCCD regions having a predetermined interval from one another; a plurality of HCCD regions formed at the end of the VCCD regions in the direction of column; a plurality of photodetectors regularly arranged between the VCCD regions, the photodetectors generating signal charges according to an image signal; a plurality of vertical gate electrodes formed on the VCCD regions and the photodetectors in the direction of column, the vertical gate electrodes transmitting the signal charges of the photodetectors to the HCCD regions through the VCCD regions according to applied vertical clock signals; vertical clock signal generator for supplying a predetermined number of vertical clock signals; and a selecting portion for receiving vertical clock signals from the vertical clock signal generator, the selecting portion supplying the vertical clock signals to part of the vertical gate electrodes, or supplying disable signals instead of the vertical clock signals, according to an external selection signal.
