Abstract
When a focus setting part and a zoom setting part are operated, a control box, connected to a lens system, outputs a driving signal to the lens system and thereby moves a focus lens and a zoom lens to a position directed by the setting parts. At that time, if only the focus setting part is operated to move the focus lens, a zoom position where a view angle is maintained constant is obtained from correction data which is recorded in a lens view angle correction data part, and a driving signal for moving the zoom lens to the zoom position is output to the lens system.
