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.
