Abstract
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.
Claims44
A camera module comprising:
- a frame accommodating a lens barrel;
- and
- a housing accommodating the frame,
- wherein the frame is pressed toward one surface of the housing in a state in which the frame is relatively aligned with respect to the housing.
A camera module comprising:
- a lens barrel;
- a frame accommodating the lens barrel;
- an elastic member connected to the frame;
- and
- first and second cases accommodating the frame and coupled to each other so that the elastic member presses the frame so as to be aligned in a pressing direction of the elastic member.
A camera module comprising:
- a frame accommodating a lens barrel;
- a housing accommodating the frame;
- and
- an elastic member pressing the frame toward one surface of the housing,
- wherein the housing has an opening exposing a portion of the frame to an outside of the housing.
A camera module comprising;
- a housing providing an internal space;
- and
- a frame including a lens barrel, disposed in the internal space of the housing, and pressed toward one surface of the housing,
- wherein the frame is aligned in the housing in a state in which a gap is formed between a side wall of the frame and a side wall of the housing.
A camera module comprising:
- a frame accommodating a lens barrel;
- a housing in which the frame is disposed;
- and
- an elastic member pressing the frame toward one surface of the housing,
- wherein the frame is aligned in the housing by pressing force of the elastic member.
A camera module comprising:
- a frame accommodating a lens barrel;
- a housing in which the frame is disposed;
- and
- an elastic member pressing the frame toward one surface of the housing,
- wherein the frame is supported by the elastic member in a state in which the frame is tilted with respect to the housing so that larger force is applied to a portion of the elastic member than a remaining portion of the elastic member.
A method for aligning an optical axis of a camera module, the method comprising:
- disposing a frame including a lens barrel inside a housing so as to be pressed toward one surface of the housing by an elastic member;
- measuring a tilted state of an optical axis of a lens accommodated in the lens barrel;
- moving at least a portion of the frame depending on whether the tilted state of the optical axis is within a preset range to correct the tilted state of the optical axis;
- and
- fixing the frame to the housing.
A method for aligning an optical axis of a camera module, the method comprising:
- disposing a frame including a lens barrel inside a housing so as to be pressed toward one surface of the housing by an elastic member;
- measuring a tilted state of an optical axis of a lens accommodated in the lens barrel;
- and
- fixing the frame to the housing after moving at least a portion of the frame depending on the tilted state of the optical axis to correct the tilted state of the optical axis of the lens.
A camera module, comprising:
- a frame for a lens barrel;
- a housing accommodating the frame;
- and
- an elastic member disposed between the frame and one surface of the housing and configured to movably press the frame against another surface of the housing by elastic force.
