Abstract: There is provided a method of controlling a mechanical shutter that can ensure faster shutter speed by preventing a reduction of the shutter speed of the mechanical shutter caused by signal loss and physical loss caused by inertia. A method of controlling a mechanical shutter according to an aspect of the invention may include performing a row reset operation to remove image information remaining in an image sensor according to input of a trigger event generated by a user to acquire an image; transmitting a shutter close operation start signal for a mechanical shutter to the mechanical shutter before the row reset operation ends after a predetermined delay time from a time when the row reset operation starts; exposing the imager sensor right after the row reset operation ends; and fully closing the mechanical shutter.

Abstract: An apparatus for driving a lens in a camera includes a lens module installed in a reciprocating and sliding manner in an inside of a lens barrel, a lead screw installed on the lens barrel, for being rotated by a driving motor, and a power transferring member assembled on the lens module and equipped with a tooth-shaped part that corresponds to a tooth shape of the lead screw. The lens module has a lens and a slider having a mounting unit for mounting the lens and receiving the power transferring member in a movable manner. The mounting unit has a through groove in which one end of the power transferring member is fit and supported and a slit groove in which the other end of the power transferring member is fit to be supported for being movable in a direction perpendicular to the movement direction of the slider.

Abstract: A motor to drive an iris diaphragm having a motor housing formed within the lens barrel to provide a light path, a stator assembly supported in the motor housing, and a rotor rotatably disposed within the stator assembly to move the iris diaphragm by a movement thereof, the rotor having a center aperture through which a light passes. Additionally, an iris diaphragm driving apparatus has an iris diaphragm installed in a lens barrel, and a motor which is installed in the lens barrel and drives the iris diaphragm in accordance with a movement thereof.
