Abstract
Solid state image pickup device in which a horizontal charge coupled device (HCCD) region is divided into multi-channels so as to improve efficiency of charge-transferring and to widen its dynamic range is disclosed, including a plurality of photoelectric conversion regions; vertical charge coupled device (VCCD) regions for transferring in a vertical direction image charge generated in the photoelectric conversion regions; horizontal charge coupled device (HCCD) regions for dividing the image charge into one channel or two channel according to a level of the image charge transferred in a vertical direction and for transferring it in a horizontal direction; and a floating diffusion region for sensing only the image charge transferred through any one of the channels of the HCCD regions and draining the image charge transferred through the other channel without sensing it.
