Abstract:
A camera module includes a lens barrel including at least one lens group; a moving frame that includes the lens barrel and moves in an optical axis direction and in a first direction and a second direction that are perpendicular to the optical axis direction; a fixed frame that movably supports the moving frame and provides the moving frame with a driving force in the optical axis direction, a driving force in the first direction, and a driving force in the second direction; and a base that fixes the fixed frame and includes an image sensor that is spaced apart from the at least one lens group in the optical axis direction.
Abstract:
An optical image-stabilizing apparatus includes: an optical image-stabilizing unit including a movement frame and a support frame supporting the movement frame to be movable in a direction perpendicular to an optical axis; and a locking unit capable of locking the movement frame to not be moved in the direction perpendicular to the optical axis, wherein the locking unit includes: a locking barrel movable in a direction parallel to the optical axis and configured to limit movement of the movement frame according to a position in the direction parallel to the optical axis; a driving barrel rotatable and configured to transfer a driving force to the locking barrel so that the locking barrel is moved in the direction parallel to the optical axis; and a guide barrel between the locking barrel and the driving barrel and including rectilinear guide portions that extend in the direction parallel to the optical axis so that the locking barrel is moved in the direction parallel to the optical axis.
Abstract:
A small camera apparatus includes a base, a lens barrel, a lens driving assembly, and a first flexible printed circuit board. The lens barrel is disposed to be spaced apart from the image sensor in an optical axis direction and has at least one lens. The lens driving assembly has a supporting frame, a first moving frame supported on the supporting frame to be movable in the optical axis direction, and a second moving frame loaded with the lens barrel and supported on the first moving frame to be movable in directions perpendicular to to the optical axis direction. The first flexible printed circuit board (FPCB) provides an electrical signal, for driving the second moving frame, to the first moving frame. At least a portion of the first FPCB is bent and is disposed between the base and the first moving frame. At least a portion of the bent portion is bonded to reduce a bending tension that occurs in a direction opposite to a bending direction when the first FPCB is bent.
Abstract:
Disclosed is a handshake correction apparatus of a photographing apparatus. The handshake correction apparatus includes a lens support plate that supports a correction lens and operates in a direction perpendicular to an optical axis; a base that supports the lens support plate to be movable; and magnets and driving coils which are assembled on the lens support plate and the base to face each other, wherein the magnets are tight-fitted in assembly grooves of the lens support plate or the base, and wherein one or more protrusions that protrude from internal walls of the assembly grooves toward the magnets and elastically press the magnets are formed in the assembly grooves. Control performance of a correction operation of the handshake correction apparatus may be improved by ensuring alignment between assembly structures of assembly parts including magnets and yokes.
