Abstract: An imaging device includes: a pixel that outputs a pixel signal corresponding to incident light; a comparator that compares the pixel signal with a reference signal and generates an output signal that indicates a comparison result; a counter that generates a digital signal corresponding to the pixel signal by counting the number of periods until the output signal is inverted, the counter including first to fourth counter parts, each of which corresponds to one of bits included in the digital signal; a memory that stores the digital signal, the memory including first to fourth memory parts corresponding to the first to fourth counter parts; and first and second lines. The first and third counter parts are respectively connected to the first and third memory parts through the first line. The second and fourth counter parts are respectively connected to the second and fourth memory parts through the second line.

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.
