Abstract:
A charge coupled device, comprising:a plurality of photo diode areas arranged in the form of a matrix, receiving the image signals with respect to lights and then generating charges corresponding to the images;a plurality of VCCDs for shifting the image charges generated in the photo diode areas according to a potential well variation;a plurality of first and second polysilicon gate electrodes insulatedly formed on the VCCDs, and making the charge transmission direction of the VCCDs take on a first direction by vertical clock signals V.phi.1, V.phi.2, V.phi.3, V.phi.4 or take on a second direction by shifted vertical clock signals V.phi.1, V.phi.2, V.phi.3, V.phi.4;first and second HCCDs formed respectively on one side and the other side of the VCCDs and thereby transmitting the image charges transmitted through the VCCDs in the first and second directions, respectively, to form one of a normal image and a reverse image;a first sensing amplifier formed on one side of the first HCCD, and externally sensing and outputting the transmitted image charges; anda second sensing amplifier formed on one side of the second HCCD, sensing and outputting the transmitted image charges to outside.
