Abstract
An imaging device includes an imaging unit, a reference signal generation unit, m (m is an integer of 3 or more) number of column delay units, and a plurality of column AD conversion units. The plurality of column delay units is arranged so as to correspond to two or more and less than m of the column AD conversion units. Each of the plurality of column delay units includes a first delay circuit. The first delay circuit generates a plurality of first delay clocks. The column AD conversion unit includes a comparison unit, a latch unit, and a counter unit. The comparison unit compares a pixel signal with a reference signal, and outputs a control signal corresponding to a comparison result. The latch unit includes a plurality of latch circuits that latches the plurality of first delay clocks on the basis of a state change of the control signal.
