1. A three-dimensional image-capturing apparatus comprising:
- an image-capturing device having a plurality of image-capturing regions; and
a plurality of optical systems for forming images of a subject in the image-capturing regions, the optical systems including(1) a plurality of reflection units which reflect rays from said subject a number of times,(2) at least one lens provided to be closer to said image-capturing device than the closest reflection unit to said subject, and(3) a light-limiting unit provided between said plurality of reflection units, wherein,at least one reflection unit is an imaging-side reflection unit located in front of the corresponding image-capturing region and directed in an obliquely outward direction,at least one reflection unit is a subject-side reflection unit located outward from said imaging-side reflection unit and directed in an obliquely inward direction,the light-limiting unit is located closer to the subject side reflection unit and is effective to only exclude rays closer to the subject side reflection unit with a greatest angle of incidence on the image sensing device, andsaid reflection unit and said lens are used to form, in said image-capturing regions, separate images of said subject which are captured from different viewpoints having a distance therebetween.

Abstract
A three-dimensional image-capturing apparatus includes an image-capturing device having a plurality of image-capturing regions and a plurality of optical systems for forming images of a subject in the image-capturing regions. The optical systems includes a plurality of reflectors for reflecting rays from the subject a number of times and at least a lens provided to be closer to the image-capturing device than the reflection means closest to the subject. The reflectors and the lens are used to form, in the image-capturing regions, separate images of the subject which are captured from different viewpoints.
