Solid-state imaging device and driving method of solid-state imaging device

A solid-state imaging device comprising:

• photo diodes which are arranged two-dimensionally;
• first column charge coupled devices (CCDs) each of which is provided to a corresponding one of columns of said photo diodes, reads charges from said photo diodes provided to the corresponding column, and transfers the charges in a column direction;
• a row CCD which transfers, in a row direction, part of the charges transferred by said first column CCDs;
• a drain into which the rest of the charges transferred by said first column CCDs are swept-off;
• and
• transfer control units each of which is provided to corresponding said first column CCDs, and transfers, to said row CCD and to said drain, the charges transferred by said corresponding first column CCDs,
• wherein each of said transfer control units includes:
• a second column CCD which transfers, in a column direction, the charges transferred by said first column CCDs corresponding to said transfer control unit;
• and
• a column CCD terminal gate which is provided between said second column CCD and the row CCD, and forms a potential barrier between said second column CCD and said row CCD.
