Abstract:
A lens control unit for outputting a signal corresponding to displacement of a control member and controlling a position of a lens according to the signal, the lens control unit comprising:the control member; a stopper member for defining an operational limit of and which impacts with the control member to thereby mechanically prevent subsequent movement of the control member; a support mechanism for movably supporting the stopper member; a power source for supplying power to the support mechanism to move the stopper member; a control part for controlling the power source to move the stopper member so that the operational limit of the control member with respect to a current position of the control member corresponds to a movement end of the lens with respect to a current position of the lens; and preset functions for automatically moving the lens to a subsequent position according to prestored lens position data, wherein the functions are activated to move the stopper member to correct displacement between the operational limit of the control member and the movement end of the lens.
