发明名称 Lens driving control apparatus for zoom lens
摘要 A lens driving control apparatus for a zoom lens includes a zooming operation member for operating a zoom part of the zoom lens, a focusing operation member for operating a focusing lens part of the zoom lens, and a control circuit for driving and controlling the zoom part. The control circuit computes information about driving of the zoom part for substantially preventing a change of angle of view resulting from movement of the focusing lens part, on the basis of an operation signal of the zooming operation member and an operation signal of the focusing operation member or a position signal of the focusing lens part and a position signal of the zoom part, and drives and controls the zoom part in accordance with the computed information.
