Patent ID: 8174595

Claim:
A drive unit for an X-Y scanning type image sensor having an RGB Bayer array color filter, comprising: for horizontal scanning, a drive section performing addition and readout of a first FD (floating diffusion) shared by two pixels of the same color that are adjacent in a diagonal direction by simultaneously transferring electrical charge of the two pixels of the same color, and for a second FD shared by two pixels of different colors that are adjacent in a diagonal direction, transferring and reading out electrical charge of a pixel of one color among the two pixels of different colors; and a horizontal adding section for adding electrical charges that are adjacent in a horizontal direction, among electrical charges for two pixels of the same color that have been added in the horizontal scanning and read out, and adding electrical charges that are adjacent in the horizontal direction among electrical charges of associated pixels of the same color, of the two pixels of different color that have been read out in the horizontal scanning, and reading out.
