PURPOSE: A dynamic range control device of a thermal detector is provided to enable the distinguishment of targets even when passing by high temperature area. CONSTITUTION: A dynamic range control device of a thermal detector comprises an infrared detector(103), a controlling unit, and a signal processing unit(107). The infrared detector receives infrared ray from a target. The infrared ray of the specific wave penetrates the infrared detector. The controlling unit controls the quantity of light and the gain value of the incident infrared ray. The controlling unit provides the controlled quantity of light and gain value to the infrared detector. The signal processing unit creates analog signals through the infrared ray.
