Patent abstract
The lens moving mechanism may be a cam structure. The cam structure is set so that the rotation axis of the lens is held at the center of the dome in a predetermined center hold angle range corresponding to the direction of an elevation angle, and that the rotation axis of the lens is moved from the center of the dome in the zenith direction at angles lower than the center hold angle range. Good images can be obtained even when shooting in the direction of a depression angle.
