CAMERA MODULE INCLUDING APERTURE
First Claim
1. A camera module comprising:
- a housing;
a lens assembly received in the housing, the lens assembly including at least one lens;
an aperture including;
an aperture blade having an opening for adjusting an amount of external light incident on the at least one lens, anda rotary shaft formed on a side of the aperture blade, the rotary shaft being coupled to the lens assembly such that the aperture blade is rotatable about the rotary shaft;
a magnet disposed on the aperture to be adjacent to the rotary shaft;
at least one coil disposed on one surface of the housing so as to face the magnet;
control circuitry configured to rotate the aperture using the coil; and
a lens driving unit configured to move the lens assembly in an optical axis direction of the lens.

Abstract
A camera module is provided. The camera module includes a housing, a lens assembly received in the housing and including at least one lens, an aperture including an aperture blade having an opening for adjusting an amount of external light incident on the at least one lens and a rotary shaft formed on a side of the aperture blade, in which the rotary shaft is coupled to the lens assembly such that the aperture blade is rotated about the rotary shaft, a magnet disposed on the aperture so as to be adjacent to the rotary shaft, at least one coil disposed on one surface of the housing so as to face the magnet, control circuitry that rotates the aperture using the coil, and a lens driving unit that moves the lens assembly in an optical axis direction of the lens.
