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

Claim 0:
1. 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 wave plate that converts linearly polarized light aligned in the first polarization direction by the first polarizer into circularly or elliptically polarized light;
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 first pupil region and has been converted into the circularly or elliptically polarized light;
a third polarizer that transmits light in a third polarization direction different from the first polarization direction and the second polarization direction in the light which has been transmitted through the second pupil region and has been converted into the circularly or elliptically polarized light;
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 and a second pixel receiving light in different polarization directions; and
an image generation unit that performs a crosstalk removal process on pixel signals of the first pixel and the second pixel and 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 the pixel signals subjected to the crosstalk removal process.
