PROBLEM TO BE SOLVED: To appropriately prevent the fluctuation of a viewing angle without delay in viewing angle correction operation at the transition time when a focus lens is moved by obtaining the correction position of a zoom lens for preventing the fluctuation of the viewing angle caused by the movement of a focus lens with respect to the target position of the focus lens commanded by a focus control signal and moving the zoom lens to the obtained position with the movement of the focus lens. SOLUTION: When a CPU 42 acquires the focus control signal from a focus controller 28, it obtains the position of a zoom lens 50 for preventing the fluctuation of the viewing angle with respect to the position of a focus lens 56 moving according to the focus control signal based on viewing angle correction data. Then, the lens 50 is set at the obtained position synchronizing with the movement of the focus lens 56. |
