Abstract
Optical equipment capable of stopping a lens in a position producing no image blur and requiring low power consumption is provided. The optical equipment includes a lens driving unit for driving a focusing lens. The equipment further includes a drive-setting unit configured to set an optimal drive amount for positioning the focusing lens at an appropriate focal depth while minimizing the amount of power consumed in the process. The optical equipment includes a lens position-control unit that controls the lens driving unit based on the drive amount set by the drive-setting unit controlling the movement of the focusing lens. The lens position-control unit can stop the lens in a position producing no image blur and requiring low power consumption.
