Abstract: A signal processing circuit for detecting an uncooled infrared image is provided to detect a high definition infrared image by adjusting integrating time proper to limit noise bandwidth. A signal processing circuit for detecting an uncooled infrared image comprises an infrared detecting part(110), a reference resistor part(120), and an integrator(130). The infrared detecting part, whose one end is grounded, has a first resistance value when infrared is not absorbed and a second resistance value smaller than the first resistance value when infrared is absorbed. The reference resistor part, whose one end is connected to the other end of the infrared detecting part and the other end is connected to a first reference voltage, has a second resistance value larger than the first resistance value. The integrator outputs an integrated value in an infrared signal by integrating a difference between the voltage of the other end of the infrared detecting part and a second reference voltage.
