Title:
IMAGING DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/029843
Kind Code:
A1
Abstract:
An imaging device that adjusts the amount of light incident to an image sensor via each optical system, prevents interference, and comprises: an imaging optical system comprising a first optical system and a second optical system each having different imaging characteristics and being combined concentrically; and an image sensor comprising a plurality of pixels comprising photoelectric conversion elements arranged two-dimensionally, said image sensor pupil-dividing each light beam incident via the first and second optical systems and selectively receiving light by using the pixels. An aperture (200) is provided that adjusts the volume of light that passes through the first optical system (120) and the second optical system (130). The aperture comprises an annular light-shielding section having an inner diameter and an outer diameter that are expandable, expands the inner diameter and the outer diameter of the light-shielding section at the boundary of the pupil areas of the first and second optical systems, and adjusts the amount of light that passes through the first and second optical systems.
