摘要

Disclosed is a device and method for opening and closing a barrier in a zoom camera. The device includes a connection lever fixed to a lens barrel of a focus lens group and rotated by the transmission of a rotational power of a focusing motor; and a barrier driving unit including a barrier driving lever contacting the connection lever to receive rotational force of the connection lever and a ring portion for pushing sector pins of barrier sectors in a direction to close the barrier sectors. The method includes the steps of determining if a power switch has been turned ON in an initialized state; opening barrier sectors by operating a barrier driving unit according to operating signals of a control unit if it is determined that the power switch has been turned ON; protecting a lens of the zoom camera by closing the barrier sectors or retracting a movable lens barrel in a state where the barrier sectors are open if it is determined that a first release switch has not been turned ON during a first or second predetermined interval of time, respectively; and performing photographing according to operating signals of the first release switch and a second release switch.
