发明名称 Image capture apparatus and zoom lens control method for the same
摘要 An image capture apparatus includes: a zoom motor which drives a target object of a retractable zoom lens drive mechanism; a driver for the zoom motor; a reference position detector detecting reference positions of the target object by using edges provided by each of two reset sensors; a position determination section determining as to a current position of the target object based on a current combination of outputs of the two reset sensors, a history of past outputs of the two reset sensors, and a driving direction of the target object; and a controller controlling drive of the zoom motor so as to drive the target object in a direction in which an arbitrary edge at one of the reference positions exists, in accordance with a determination result of the current position of the target object.
