Abstract: A photographing device for photographing a monitored area has a state diagnosis of a camera using a stereo camera configured by two or more cameras. A diagnostic pattern database is provided in which information on a plurality of images having different photographing conditions obtained by the stereo camera are stored in advance as diagnostic patterns. Disparity information is acquired based on image data from the stereo camera and a state diagnosis of the camera is performed by determining whether the camera is abnormal or normal based on the disparity information with reference to the information on the plurality of images having different photographing conditions stored in the diagnostic pattern database. Upon receiving a result of the state diagnosis, at least one of illumination control, shutter control, and posture control of the camera or the stereo camera is performed.
