An unmanned aerial vehicle includes an imaging camera configured to capture the image of an object to be inspected, an object detecting unit configured to detect a relative position of the object to be inspected, a camera angle adjusting unit configured to control the angle of an image capturing direction of the imaging camera on the basis of the relative position detected by the object detecting unit, a determination unit configured to determine whether the image of the object to be inspected is moved out of a video frame of the imaging camera during an image capture operation performed by the imaging camera, and a storage unit configured to store image capture failure information including the result of determination if the determination unit determines that the image of the object is moved out of the video frame.
