Abstract

A camera module according an embodiment includes: a lens assembly, an image sensor, an optical image stabilization (OIS) carrier configured to simultaneously rotate the lens assembly and the image sensor based on an axis perpendicular to an optical axis, a housing, a first OIS coil disposed to a first side surface of the OIS carrier, a second OIS coil disposed to a second side surface of the OIS carrier, a first OIS magnet disposed to face the first OIS coil, a second OIS magnet disposed to face the second OIS coil, a frame including a first portion disposed between the third side surface of the OIS carrier opposite the first side surface and the housing and including at least one first guide portion, and a second portion extending from the first portion and disposed between the fourth side surface of the OIS carrier opposite the second side surface and the housing, at least one first object disposed between the first portion and the third side surface, and at least one second object disposed between the second portion and the housing. The at least one first object may be configured to roll along the at least one first guide portion based on the OIS carrier rotating.

First claim

What is claimed is:

1. A camera module comprising:
a lens assembly comprising at least one lens aligned along an optical axis;
an image sensor configured to convert light received through the at least one lens into an electrical signal;
an optical image stabilization (OIS) carrier configured to tilt the lens assembly and the image sensor;
a housing accommodating the lens assembly, the image sensor and the OIS carrier;
a first OIS coil disposed to a first side of the OIS carrier;
a second OIS coil disposed to a second side of the OIS carrier different with the first side;
a first OIS magnet disposed to face the first OIS coil;
a second OIS magnet disposed to face the second OIS coil;
a frame comprising a first portion disposed between a third side of the OIS carrier opposite the first side and the housing and including at least one first guide portion, and a second portion extending from the first portion and disposed between a fourth side of the OIS carrier opposite the second side and the housing;
at least one first object movably disposed between the first portion and the third side, and configured to enable movement of the OIS carrier; and
at least one second object movably disposed between the second portion and the housing, and configured to enable movement of the frame and the OIS carrier,
wherein the at least one first object is configured to move along the at least one first guide portion as the OIS carrier tilts.

2. The camera module of claim 1 , wherein the first portion comprises at least one second guide portion opposite the at least one first guide portion with respect to a reference axis along which the OIS carrier tilts.

3. The camera module of claim 1 , wherein the at least one second object is configured to move along an at least one third guide portion formed on one surface of the housing facing the second portion as the OIS carrier tilts.

4. The camera module of claim 3 , wherein the second portion comprises at least one fourth guide portion opposite the at least one third guide portion with respect to a reference axis along which the frame and the OIS carrier tilt.

5. The camera module of claim 1 , wherein the first portion of the frame comprises at least one first magnet, and the second portion of the frame comprises at least one second magnet,
wherein the third side comprises at least one first yoke facing the at least one first magnet, and
wherein an inner side of the housing facing the second portion comprises at least one second yoke facing the at least one second magnet.

6. The camera module of claim 1 , wherein the third side comprises at least one first protrusion protruding in a direction toward the first portion of the frame,
wherein the first portion of the frame comprises at least one first accommodating portion accommodating the at least one first protrusion, and
wherein the at least one first protrusion is disposed and configured to move along the at least one first accommodating portion as the OIS carrier tilts.

7. The camera module of claim 1 , wherein an inner side of the housing facing the second portion of the frame comprises at least one second protrusion protruding in a direction toward the second portion of the frame,
wherein the second portion of the frame comprises at least one second accommodating portion accommodating the at least one second protrusion, and
wherein the at least one second protrusion is disposed and configured to move along the at least one second accommodating portion as the OIS carrier tilts.

8. The camera module of claim 1 , wherein the OIS carrier comprises a printed circuit board surrounding at least a part of at least one side of the OIS carrier, and
wherein the printed circuit board comprises the first OIS coil and the second OIS coil disposed on an outer side of the printed circuit board, and an auto-focus (AF) coil disposed on an inner side of the printed circuit board facing the fourth side.

9. The camera module of claim 1 , further comprising a driving circuit electrically connected to the first OIS coil and the second OIS coil, and
wherein the driving circuit is configured to control the OIS carrier to move on a plane perpendicular to the optical axis, by controlling a current applied to at least one of the first OIS coil or the second OIS coil.

10. The camera module of claim 1 , wherein the first portion of the frame comprises at least one first curved portion formed facing the housing.

11. The camera module of claim 1 , wherein the second portion of the frame comprises at least one second curved portion facing the fourth side of the OIS carrier.

12. The camera module of claim 1 , wherein the first side of the OIS carrier comprises at least one first protrusion protruding in a direction toward the first OIS coil,
wherein the second side of the OIS carrier comprises at least one second protrusion protruding in a direction toward the second OIS coil,
wherein the first OIS coil is fixed to the OIS carrier by the at least one first protrusion, and
wherein the second OIS coil is fixed to the OIS carrier by the at least one second protrusion.

13. The camera module of claim 1 , comprising:
a third OIS coil disposed to the first side of the OIS carrier, and disposed parallel to the first OIS coil; and
a fourth OIS coil disposed to the second side of the OIS carrier substantially perpendicular to the first side, and disposed parallel to the second OIS coil.

14. An electronic device comprising a first camera module,
wherein the first camera module comprises:
a lens assembly comprising at least one lens aligned along an optical axis;
an image sensor configured to convert light received through the at least one lens into an electrical signal;
an optical image stabilization (OIS) carrier configured to tilt the lens assembly and the image sensor;
a housing accommodating the lens assembly, the image sensor and the OIS carrier;
a first OIS coil disposed to a first side of the OIS carrier;
a second OIS coil disposed to a second side of the OIS carrier different with the first side;
a first OIS magnet disposed to face the first OIS coil;
a second OIS magnet disposed to face the second OIS coil;
a frame comprising a first portion disposed between a third side of the OIS carrier opposite the first side and the housing and including at least one first guide portion, and a second portion extending from the first portion and disposed between a fourth side of the OIS carrier opposite the second side and the housing;
at least one first object movably disposed between the first portion and the third side and configured to enable the movement of the OIS carrier; and
