Abstract
The present invention provides a lens controller which electrically controls a focus and a zoom of a taking lens, the lens controller comprising: an AF control device which automatically controls the focus of the taking lens so that a given subject imaged by the taking lens is in focus; and a view angle correction device which keeps an angle of view of the taking lens constant by moving the zoom of the taking lens to prevent a variation of the angle of view associated with a movement of the focus moved by the AF control device; wherein, when the focus is moved by the AF control device, the view angle correction device detects a current position of the focus by a position detecting device, obtains a position of the zoom for preventing the variation of the angle of view based on the detected current position of the focus, and moves the zoom to the obtained position.
