摘要:
A lens drive control apparatus of the present invention controls a lens drive system that has a lens frame that holds a lens so as to be movable forward and backward in an optical axis direction of an optical lens, and a transmitting member that transmits to the lens frame a driving force generated by a strain deformation of a shape memory alloy member that exhibits a predetermined hysteresis characteristic between a temperature and an amount of deformation. The lens drive control apparatus includes a control section that, at a timing at which an instruction that causes the lens frame to move forward or backward stops, performs control that changes a temperature of the shape memory alloy member to a temperature belonging to a dead zone of the predetermined hysteresis characteristic.
