A solid-state imaging device comprises a plurality of pixel blocks arranged in a matrix, each of the pixel blocks including a plurality of pixels that generate a charge in response to input light; a control unit including a vertical scanning unit and a horizontal scanning unit; and a plurality of analog-to-digital converters, each of the analog-to-digital converters disposed corresponding to pixel blocks. The control unit is configured to sequentially scan the pixels at a timing so that adjacent pixels which are located on a boundary of adjacent pixel blocks are scanned simultaneously.
