摘要:
An imaging device of the present disclosure includes: a signal generation circuit that is configured to generate a first control signal; a first selection control circuit that is configured to generate a plurality of first selection signals; and a plurality of pixel circuits each including a light-receiving element, an accumulation section, a first switch, a first circuit, and a comparator circuit. The light-receiving element is configured to generate electric charge corresponding to an amount of received light. The accumulation section is configured to accumulate the electric charge generated by the light-receiving element. The first switch is configured to couple the light-receiving element to the accumulation section by being turned on. The first circuit is configured to control an operation of the first switch on the basis of one of the plurality of first selection signals and the first control signal. The comparator circuit is configured to compare a pixel signal including a voltage in the accumulation section with a reference signal having a ramp waveform.
