A camera module may include a lens barrel supporting a lens, a frame in which the lens barrel is provided, and a housing accommodating the frame. The frame may be pressed toward one surface of the housing to thereby be relatively aligned in the housing so that an optical axis of the lens is positioned perpendicularly with respect to an image formation surface of an image sensor.

Camera module, method for aligning optical axis of camera module and portable electronic device including camera module

An electronic device is provided. The electronic device includes a housing including a first surface facing a first direction, a second surface facing a second direction opposite to the first direction, and a side surface extending between and along a perimeter of the first surface and the second surface, a cover glass corresponding to at least the first surface, a display panel disposed under the cover glass and including an active area exposed through the cover glass, an inactive area surrounding the active area, and a printed circuit board connection portion connected to one end of the inactive area, wherein at least one opening or at least one cutaway portion is formed in the display panel, and a camera module disposed in a space formed by the at least one opening or the at least one cutaway portion and exposed through the cover glass.

Electronic device including display

A camera module includes a coil member, a magnet member, and a sensor member. The coil member is positioned on a first surface of a fixed unit. The magnet member is positioned on a movable unit and facing the coil member. The sensor member is positioned on a second surface of the fixed unit and configured to sense a position of the movable unit.

Camera module including lens module actuator

An actuator driving device includes: a linearizer configured to linearize a first signal, indicative of a displacement of a lens module, to generate a second signal; a position controller configured to generate a position control signal in response to the second signal and a control input signal indicative of a target location of the lens module; and a driver configured to drive an actuator in response to the position control signal.

Actuator driving device and camera module including the same

There is provided a lens actuator, including: a lens barrel in which at least one lens is provided on an optical axis; a magnetic part provided on one surface of the lens barrel; and a printed circuit board in which a coil pattern part generating electromagnetic force is provided, the printed circuit board having one surface facing the magnetic part, wherein magnetic material is provided on the other surface of the printed circuit board.

Lens actuator

Disclosed herein is a camera module in which a movement of a magnet is controlled by only magnetic force between the magnet and a yoke without a spring for controlling the movement of the magnet which operates up and down. The camera module includes: a lens module; and a main frame supporting the lens module and allowing the lens module to be driven in an optical axis direction, wherein the lens module includes: a lens assembly including a plurality of lenses; and a magnet fixed to one side of the lens module, and the main frame includes: a coil facing the magnet, fixed to one side within the main frame, and generating an electric field as power is applied thereto; and a yoke disposed to face the magnet with the main frame and the coil interposed therebetween and controlling driving of the lens module by attraction with the magnet.

Camera module

Portable electronic device

There is provided a camera module including: a lens barrel having one or more lenses positioned along an optical axis; and a housing having the lens barrel therein, wherein the housing includes a first through hole into which the lens barrel is inserted and a second through hole having a diameter larger than that of the first through hole.

Disclosed herein is an image photographing device capable of being auto-focused while moving a lens barrel in an optical axis direction. The image photographing device includes: a lens barrel having at least one lens; a housing receiving the lens barrel therein so that the lens barrel moves in an optical axis direction; and an impact reducing unit elastically supporting the lens barrel in the case in which the lens barrel deviates from a set movement range, thereby primarily damping the lens barrel before the lens barrel deviates from the movement range to collide with other components positioned at an outer side of the lens barrel.

Image photographing device

A camera module according to an aspect of the invention may include: a housing; a fixed unit fixed to the inside of the housing; a lens barrel provided in the housing and having at least one lens; and a moving unit moved and supported by the fixed unit by a predetermined magnetic force, and moving the lens barrel along an optical axis, such that driving accuracy and reliability can be increased when performing auto focus or zoom.

An actuator used for a camera module and controlling a lens assembly to move along an optical axis, includes a magnet disposed on a side of the lens assembly, a coil part disposed within a magnetic field of the magnet and controlling an up-and-down movement of the lens assembly when an electric power is applied, and a yoke part disposed to horizontally move the magnet disposed on the side of the lens assembly. The lens assembly is provided with a friction-generating member generating a frictional force to the lens assembly in an opposite direction to a direction in which the lens assembly moves to the yoke part.

Actuator, method of controlling the same, and camera module including the actuator
