  • Abstract
    A new structure of a 242H(Horizontal elements) X 490V(Vertical elements) CCD imager has been developed and used to build a solid state color camera with high blue sensitivity. The device has been organized for a frame transfer CCD with SiO2exposed photosensor arrays. The quantum efficiency of 55% has been obtained at 450nm wavelength in the spectral response of the photosensors. The fat "1" storing part is introduced to improve the transfer efficiency of the vertical shift registers. In the constructed color camera using three CCD chips, offsetting the Red and Blue CCD chips spatially by 1/2 pixel with respect to the Green in the horizontal direction, the horizontal image resolution of 280 TV lines per picture height has been obtained.
