Abstract
A dual lens optical system includes a first optical system redirecting an optical axis of light representing an image of an object by 90° to form an image on a image sensor, and a second optical system having a movable reflection member configured to be selectively positioned on the part of the redirected optical axis of the optical axis of light passing through the first optical system, and redirecting the light representing the image of the object by 90° using the movable reflection member to form an image on the image sensor, wherein the first optical system and the second optical system share lenses and the image sensor located after the movable reflection member along an optical path.
Claims19
An imaging device having a dual lens optical system, the device comprising:
- an image sensor for photoelectrically converting an image light coming from an object into an electric signal;
- a first optical system redirecting a first optical axis of light representing an image of an object by 90° to form an image on the image sensor;
- and
- a second optical system including a movable reflection member configured to be selectively positioned in the first redirected optical axis of light, and redirecting a second optical axis of light representing the image of the object by 90° to form an image on the image sensor,
- wherein the first optical system and the second optical system share at least one lens element and the image sensor is disposed after the movable reflection member along an optical path.
A digital camera having a zoom optical system and a single-focus optical system having a focal length shorter than the focal length of the zoom optical system, the digital camera having an image sensor, a focus lens, and a first zoom lens group, arranged on a first optical axis,
- the zoom optical system comprising a first incident lens on which light representing the image of an object is incident at a second optical axis, a first light redirection member for redirecting the light incident on the first incident lens to be substantially coincident with the first optical axis, and a second zoom lens group,
- the single-focus optical system comprising a second incident lens on which light representing the image of an object is incident at a third optical axis, a second light redirection member for redirecting the light incident on the second incident lens to be substantially coincident with the first optical axis.
