Abstract
An aperture module includes a rotation plate disposed on a base, a moving portion that moves linearly to rotate the rotation plate, and blades linked to the rotation plate to form an aperture having a variable size. The blades include at least two small-aperture blades that are contracted inwardly toward an optical axis to form the aperture having a first size and at least two medium-aperture blades that are contracted inwardly toward the optical axis to form the aperture having a second size larger than the first size. The at least two small-aperture blades and the at least two medium-aperture blades are extended outwardly away from the optical axis to form the aperture having a third size larger than the second size.
Claims22
An aperture module comprising:
- a rotation plate disposed on a base;
- a moving portion configured to move linearly to rotate the rotation plate;
- and
- blades linked to the rotation plate and configured to form an aperture having a variable size,
- the blades comprise at least two small-aperture blades configured to be contracted inwardly toward an optical axis to form the aperture having a first size,
- the blades comprise at least two medium-aperture blades configured to be contracted inwardly toward the optical axis to form the aperture having a second size larger than the first size, and
- the at least two small-aperture blades and the at least two medium-aperture blades are configured to be extended outwardly away from the optical axis to form the aperture having a third size larger than the second size.
An aperture module comprising:
- a rotation plate disposed on a base;
- a moving portion configured to move linearly to allow the rotation plate to rotate;
- and
- blades linked to the rotation plate and configured to form an aperture having a variable size,
- wherein the blades comprise at least two small-aperture blades configured to be contracted inwardly toward an optical axis to form the aperture having a first size when the moving portion is moved to a first end of a linear path and configured to be extended outwardly away from the optical axis when the moving portion is disposed at a predetermined position of the linear path between the first end and a second end of the linear path,
- the blades comprise at least two medium-aperture blades configured to be contracted inwardly toward the optical axis to form the aperture having a second size larger than the first size when the moving portion is disposed at the predetermined position, and
- all of the blades are configured to extend outwardly away from the optical axis when the moving portion moves to the second end of the linear path.
A camera module, comprising:
- a housing;
- a lens module accommodated in the housing and comprising a lens barrel having one or more lenses;
- an aperture module disposed between an object and the lens module and configured to adjust an amount of incident light on the one or more lenses, the aperture module comprising:
- a moving portion configured to move along a linear path;
- and
- blades configured to rotate based on movement of the moving portion along the linear path to form an aperture through which the incident light passes, the blades comprising at least two first blades configured to be rotated inwardly toward an optical axis to form the aperture having a first size and at least two second blades configured to be rotated inwardly toward the optical axis independently of the at least two first blades to form the aperture having a second size larger than the first size.
