Abstract

A camera module includes a lens module having lenses; a reflection module disposed on an object side of the lens module, and changing a path of light so that the light incident inside is directed toward the lens module; and an image sensor disposed on an image side of the lens module. The reflection module can be rotated about a first axis and a second axis perpendicular to the first axis, and an imaging plane of the image sensor includes a curved surface.

Claims (27)

1. A camera module, comprising:

a lens module comprising lenses;

a housing accommodating the lens module, the housing including an opening configured to receive incident light;

a reflection module disposed on an object side of the lens module, and configured to change a path of light so that the light incident on the reflection module is directed toward the lens module;

an image sensor disposed on an image side of the lens module and comprising a curved surface;

a first elastic member configured to elastically support the reflection module and to rotate the reflection module with respect to a first axis, the first elastic member including at least one elastic body that is connected to an inner surface of the housing facing the opening;

a second elastic member configured to elastically support the reflection module and to rotate the reflection module with respect to a second axis that is perpendicular to the first axis; and

a ball member defining a rotational center of the reflective module to support the rotation of the reflection module,

wherein the reflection module is configured to rotate with respect to the first axis and the second axis centered on the ball member.

2. The camera module of claim 1 , wherein the curved surface is concave toward the lens module.

3. The camera module of claim 1 , further comprising:

a housing accommodating the reflection module.

4. The camera module of claim 3 , further comprising a first magnet mounted on a first surface in which the reflection module and the housing oppose each other in an incident direction of the light, and a first coil mounted on a second surface in which the reflection module and the housing oppose each other in the incident direction of the light.

5. The camera module of claim 4 , wherein the first elastic member comprises a first elastic body and a second elastic body, which corresponds to the at least one elastic body, respective first ends of the first elastic body and the second elastic body are connected to the housing, and respective second ends of the first elastic body and the second elastic body are connected to the reflection module, and

the first elastic body and the second elastic body are configured to allow one of the first elastic body and the second elastic body to be compressed and the other of the first elastic body and the second elastic body to be tensioned, when the reflection module rotates.

6. The camera module of claim 3 , further comprising a second magnet mounted on a first surface in which the reflection module and the housing oppose each other in a direction perpendicular to an incident direction of the light, and a second coil mounted on a second surface in which the reflection module and the housing oppose each other in the direction perpendicular to the incident direction of the light.

7. The camera module of claim 6 ,

wherein the second elastic member comprises a third elastic body and a fourth elastic body, respective first ends of the third elastic body and the fourth elastic body being connected to the housing, and respective second ends of the third elastic body and the fourth elastic body being connected to the reflection module, and

the third elastic body and the fourth elastic body are configured to allow one of the third elastic body and the fourth elastic body to be compressed and the other of the third elastic body and the fourth elastic body to be tensioned, when the reflection module rotates.

8. A camera module, comprising:

a lens module comprising lenses aligned along an optical axis;

a housing accommodating the lens module, the housing including an opening configured to receive incident light;

a reflective member configured to redirect light incident on a surface thereof toward the lens module, and configured to be rotated in two directions around an axis perpendicular to the optical axis;

an image sensor comprising a curved imaging plane configured to receive the light redirected toward the lens module after the light has passed through the lenses;

a first elastic member configured to elastically support the reflective member, the first elastic member including at least one elastic body that is connected to an inner surface of the housing facing the opening; and

a ball member defining a rotational center of the reflective member to support the rotation of the reflection member,

wherein the reflective member is configured to rotate around the axis perpendicular to the optical axis.
