ABSTRACT:
An infrared imaging device has a plurality of detectors comprising thermocouples, bolometers, or the like and a scanner for scanning the detectors. To prevent all pixels corresponding to the detectors from failing to operate due to a charge overflow that occurs when some of the detectors are broken, a bypass circuit in the form of a bypass resistor, and a diode, or the like, is connected parallel to each of the detectors for limiting the output signal therefrom to a predetermined voltage range. Even if a detector is broken, the output signal thereof is limited to the predetermined voltage range, thus preventing a charge overflow.
