Assignee: FUJIFILM CORPORATION
Field: Audio-visual technology (Electrical engineering)
Classification: CPC G  H | IPC G  H

Claim 6:
7. An imaging device comprising:
an imaging optical system that has a pupil region including a first pupil region and a second pupil region different from the first pupil region;
a first polarizer that aligns a polarization direction of light transmitted through the first pupil region and the second pupil region with a first polarization direction;
a second polarizer that transmits light in a second polarization direction different from the first polarization direction in the light which has been transmitted through the second pupil region and has been aligned in the first polarization direction;
a third polarizer that transmits light in a third polarization direction, which is different from the first polarization direction and is orthogonal to the second polarization direction, in the light which has been transmitted through the first pupil region and has been aligned in the first polarization direction;
an imaging element that receives the light transmitted through the first pupil region and the second pupil region and has a plurality of pixel units each of which is a set of a first pixel receiving the light in the second polarization direction and a second pixel receiving the light in the third polarization direction; and
an image generation unit that generates a first image corresponding to the light transmitted through the first pupil region and a second image corresponding to the light transmitted through the second pupil region on the basis of pixel signals of the first pixel and the second pixel.
