Abstract
An infrared sensor according to the present disclosure includes an output pixel, and a switcher. The output pixel includes infrared photodetectors. The switcher switches each of the infrared photodetectors between a first state and a second state independently with a predetermined period P. In the first state, the infrared photodetector is able to change in temperature in response to receiving infrared radiation. In the second state, the infrared photodetector is maintained at a predetermined temperature. Switching of the infrared photodetectors from the second state Sto the first state Sis executed sequentially in the period P at a predetermined time interval ti. The output pixel includes N infrared photodetectors. The time interval ti divided by the period P is greater than or equal to 1/(N+1) and less than or equal to 1/(N−1).
