Abstract
A digital camera has an optical system, an image capturing unit, an aperture adjuster, a focal point adjuster, and a body microcomputer. The aperture adjuster has an aperture included in the optical system and is capable of adjusting the state of the aperture. The focal point adjuster has a focus lens included in the optical system and is capable adjusting the focal state of the optical system by using the focus lens by contrast detection method. The body microcomputer controls the operation of the aperture adjuster so that the aperture value of the optical system will be at or below a set aperture value before the focal state is adjusted by the focal point adjuster.
Claims19
An imaging device for producing an image of a subject, comprising:
- an optical system configured to form an optical image of the subject;
- an image capturing unit configured to convert the optical image into an image signal;
- an aperture adjuster having an aperture included in the optical system and capable of adjusting a state of the aperture;
- a focal point adjuster including a focus lens disposed in the optical system and capable of adjusting a focal state of the optical system by using a contrast detection method;
- and
- a controller configured to control the aperture adjuster so that an aperture value of the optical system will be no greater than a preset aperture value set before the focal state is adjusted by the focal point adjuster.
