PELTIER CONTROLLER AND PELTIER ELEMENT CONTROL METHOD

PROBLEM TO BE SOLVED: To provide a Peltier controller and a Peltier element control method, with which the temperature of a device itself can be stabilized corresponding to the environmental temperature, power consumption can be reduced and the failure of a Peltier element caused by thermorunaway can be avoided, by resetting a set temperature so as to reduce current before the thermorunaway, to disable temperature control occurs on the Peltier element. SOLUTION: This device is provided with an image pickup device 1, Peltier element 2, current measuring part 3 for measuring the current of the Peltier element 2, temperature setting part 4 for calculating the temperature of the Peltier element 2 from the measured data of the current measuring part 3 and resetting the temperature, drive circuit part 5 for driving the Peltier element 2 on the basis of a setting signal from the temperature setting part 4, and temperature sensor 6 located on the image pickup device 1.
