A direction control device includes: a camera unit that acquires an image captured by photographing a subject by a camera targeted for adjustment of a photographing direction; an image-processing unit that calculates a position of a first setting image that represents the subject in the captured image; a posture detection unit that detects a difference between a position of a second setting image that represents the subject in a reference image registered in advance and the position of the first setting image; and a camera control unit that shifts the photographing direction of the camera based on the difference.
