US 2014/0192167 A1 · STEREOSCOPIC IMAGING DEVICE

Abstract

In the stereoscopic imaging device including a single imaging optical system, lens information (focal length, F-stop range) is acquired (step S18), and a parallax priority program diagram (F-stop is fixed) which uses a lens F-stop and a focal length within a range capable of obtaining a minimum parallax amount or more is set (step S20). In a first mode, exposure conditions including the F-stop capable of carrying out the stereoscopic imaging with a parallax amount equal to more than the minimum parallax amount is calculated using the set parallax priority program diagram to set exposure during main imaging (steps S26 and S28). In a second mode, it is determined whether or not the focal length and the F-stop which are set by a user are within a range equal to or more than the minimum parallax amount, and a user is notified of the determination result (steps S38 to S42).

Dependent claims

A stereoscopic imaging device, comprising:

a parallax-related information storage unit which stores parallax-related information indicating a relationship between a combination of an F-stop of the aperture and a focal length of the single imaging optical system, and parallax;
and
a determination unit which determines whether or not the combination of the F-stop of the aperture and the focal length of the imaging optical system is appropriate for stereoscopic imaging on the basis of the parallax-related information stored in the parallax-related information storage unit.

A stereoscopic imaging device, comprising:

an imaging device in which subject images passed through different regions of a single imaging optical system are pupil-divided and are formed, respectively, and which photoelectrically converts the subject images passed through the different regions, respectively, and outputs a plurality of parallax images;
an aperture which restricts a luminous flux incident to the imaging device;
a parallax-related information storage unit which stores parallax-related information indicating a relationship between a combination of an F-stop of the aperture and a focal length of the imaging optical system, and parallax;
a mode setting unit which sets a first mode or a second mode;
