Abstract
An imaging device includes: a first temperature detection elementthat detects temperature on the basis of infrared rays; a second temperature detection elementfor temperature reference; and a drive circuitA including a switch circuitincluding a butterfly switch circuit, a first current sourceA, a second current sourceB, a differential circuit, and an analog-digital conversion circuit. The first temperature detection elementand the second temperature detection elementare connected to a first input endA and a second input endB of the switch circuit. A first output endC and the first current sourceA are connected to a first input endA of the differential amplifier. A second output endD of the switch circuit and the second current sourceB are connected to a second input endB of the differential amplifier. An output endC of the differential amplifier is connected to an input portion of the analog-digital conversion circuit
