Solid-state image pickup device, method for driving solid-state image pickup device, and image pickup apparatus

摘要

A solid-state image pickup device includes a pixel array section including an effective pixel region, an optical black pixel region, and a pixel region between the effective pixel region and the optical black pixel region; a vertical drive section which performs driving so that signals of pixels of the pixel region disposed at a side of the effective pixel region in a vertical direction are skipped and signals of pixels of the effective pixel region and the optical black pixel region are read; and a horizontal drive section which performs driving so that, from among the pixels selected by the vertical drive section, the signals of the pixels of the pixel region disposed at a side of the effective pixel region in a horizontal direction are skipped and the signals of the pixels of the effective pixel region and the optical black pixel region are read.
