  • Color linear charge coupled device and method for driving the same
    Patent number: 6040202
    Abstract: A color linear charge coupled device for an image pickup apparatus includes red, green, and blue photo diode arrays. First, second, third and fourth transfer gates formed in the device move signal charges generated at the photo diode arrays toward first, second and third horizontal charge coupled device (HCCD) shift registers. By controlling the transfer gates, the red and green signal charges are first transferred to their HCCD shift registers. The blue signal charge is then transferred to its HCCD shift register. Only three HCCD shift registers are required, thus, the device dimension and configuration is considerably simplified compared to prior art configurations. Also, the color resolution of the device is greatly improved because the distance between the respective photo diode arrays is substantially decreased.

  • Color charge-coupled device
    Patent number: 6008843
    Abstract: A color CCD includes a plurality of photo diodes, a color filter layer for making only light of predetermined wavelength pass through to each photo diode, and a plurality of poly silicon films formed on selected photo diodes. The color filter layer may be made of any one layer of dyeing layers of magenta and cyan or two overlapped dyeing layers of magenta and cyan.
