LENS DRIVE CONTROL DEVICE AND IMAGE PICKUP DEVICE
摘要:
A lens drive control device for a lens barrel, which controls at least a part of a plurality of lens groups respectively including at least one lens, wherein a state of the lens barrel transits from a retracted state to a photographing extended state, the lens drive control device comprising: a detection device which detects that the at least one lens group reaches a reference position, and a determination device which determines an abnormal actuation based upon a detection by the detection device, upon actuation when the at least one lens group is moved from the retracted position to the position on the optical axis, wherein the determination device determines that the actuation is abnormal when the detection device detects that the at least one lens group reaches the reference position for a plurality of times.
