PROBLEM TO BE SOLVED: To provide a device that photographs and records wide and narrow areas by performing wide area photography and narrow area photography in an extremely short time and performs infrared light photography simultaneously with visible light photography with a small time lag to an extreme, and to provide a device that is miniaturized in volume and light in weight, thereby makes it possible to perform operation by being held with hands in aerial photography or the like. SOLUTION: A beam splitter is arranged in optical paths of a wide area photographic lens and a narrow area photographic lens, to guide a light beam to an infrared light image sensor and a visible light image sensor. A shutter is arranged between the beam splitter and each photographic optical system. As the shutter turns, the wide area photography and the narrow area photography are alternately performed in the extremely short time, and photographing and recording of the wide and narrow areas are performed.
