Abstract: A solid-state imaging device includes a plurality of pixels arrayed in a matrix, a plurality of first latch circuits, a first read bit line, a plurality of first driver circuits, a first amplifier, a second latch circuit, a second driver circuit, and a column scanning circuit. Each of the plurality of first latch circuits holds first pixel data which is obtained from a pixel located on the corresponding unit column. Each of the plurality of first driver circuits outputs the first pixel data, which is held in a corresponding one of the first latch circuits, to the first read bit line. The first amplifier amplifies a voltage of the first read bit line to generate first data. The second latch circuit holds the first data. The column scanning circuit sequentially outputs a plurality of the first pixel data by sequentially selecting the plurality of first driver circuits and selecting the second driver circuit. The second driver circuit outputs the first data to a read bit line different from the first read bit line.
