Abstract

A camera module includes a housing to accommodate a lens module, a stop module coupled to the lens module and configured to selectively change an amount of light incident to the lens module, and a coil portion configured to drive the stop module to selectively change an amount of light incident to the lens module. The coil portion is disposed on the housing.

Claims

1. A camera module, comprising:

a housing;

a lens module accommodated in the housing;

a stop module coupled to the lens module, and the stop module comprising one or more stop blades each comprising a light-incidence hole; and

a stop driver configured to drive at least one of the one or more stop blades,

wherein the stop driver comprises a coil provided in the housing and a magnet disposed to be opposite to the coil.

2. The camera module of claim 1, wherein the magnet is configured to move together with the lens module in an optical axis direction.

3. The camera module of claim 1, wherein the magnet is configured to be moved linearly.

4. The camera module of claim 3, wherein the magnet is configured to be moved linearly in a direction substantially perpendicular to an optical axis direction.

5. The camera module of claim 1, wherein the stop driver is configured to rotationally drive the at least one of the one or more stop blades.

6. The camera module of claim 5, wherein the stop driver comprises a magnet housing to which the magnet is fixed, and the at least one of the one or more stop blades is interlocked with the magnet housing.

7. A camera module, comprising:

a housing;

a lens module accommodated in the housing;

a stop module coupled to the lens module, and the stop module comprising one or more stop blades each comprising light-incidence holes having different sizes; and

a stop driver configured to drive at least one of the stop blades, and the stop driver comprising a coil and a magnet,

wherein the magnet is configured to interact with the coil to move linearly in a direction substantially perpendicular to an optical axis direction.

8. The camera module of claim 7, wherein the at least one of the stop blades is configured to rotate in conjunction with a linear movement of the magnet.
