Abstract
An aperture device for setting an amount of light incident on a lens of a camera module is provided. The aperture device includes: a diaphragm plate exhibiting a plate shape and formed with an aperture opening penetrating the diaphragm plate in a plate surface direction; and a configuration-changing mechanism for changing a configuration of the diaphragm plate to an aperture position or a retracted position, where the aperture position is a position where the diaphragm plate is on the lens and a center of the aperture opening is configured in a position corresponding to an optical axis of the lens, and the retracted position is a position where the diaphragm plate is retracted from the lens.
Claims21
An aperture device, comprising:
- a diaphragm plate comprising a shielding region for shielding light incident on a lens of a camera module;
- and
- a configuration-changing mechanism for changing a configuration of the diaphragm plate to an aperture position or a retracted position, wherein the aperture position is a position where the diaphragm plate is on the lens and a center of an aperture opening is located in a position corresponding to an optical axis of the lens, and the retracted position is a position where the diaphragm plate is retracted from the lens.
9-10. (canceled)
A camera module, comprising:
- a lens unit comprising a lens;
- a housing accommodating the lens;
- a power-receiving portion mounted on the housing and receiving electric power supply from outside;
- and
- an aperture device for setting an amount of light incident on the lens,
- wherein the aperture device comprises:
- a diaphragm plate comprising a shielding region for shielding the light incident on the lens;
- and
- a configuration-changing mechanism for changing a configuration of the diaphragm plate to an aperture position or a retracted position, wherein the aperture position is a position where the diaphragm plate is on the lens and a center of an aperture opening is located in a position corresponding to an optical axis of the lens, and the retracted position being a position where the diaphragm plate is retracted from the lens.
An electronic apparatus, comprising:
- a lens;
- and
- an aperture device for setting an amount of light incident on the lens,
- wherein the aperture device comprises:
- a diaphragm plate comprising a shielding region for shielding the light incident on the lens;
- and
- a configuration-changing mechanism for changing a configuration of the diaphragm plate to an aperture position or a retracted position, wherein the aperture position is a position where the diaphragm plate is on the lens and a center of an aperture opening is located in a position corresponding to an optical axis of the lens, and the retracted position is a position where the diaphragm plate is retracted from the lens.
