Patent ID: 7657168

Claim:
An image capture apparatus for controlling a retractable zoom lens drive mechanism while capturing an image of a subject via an optical system and recording image information on a recording medium, comprising: a zoom motor for driving a target object, the target object being controlled by the retractable zoom lens drive mechanism; a driver for the zoom motor; a reset detector consisting essentially of two reset sensors; a reference position section configured to detect reference positions of the target object based on edges in the outputs of the two reset sensors, wherein an edge is a switching point between output levels of the two reset sensors; a position determination section configured to determine a current position of the target object based on: a combination of the 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 configured to control the driver to drive the target object in a direction in which a desired edge at one of the reference positions exists, the direction selected in accordance with the current position of the target object.
