Classification: CPC G  H | IPC G  H

Claim 9:
10. An imaging device comprising:
an imaging optical system that has a pupil region including a first pupil region, a second pupil region different from the first pupil region, and a third pupil region different from the first pupil region and the second pupil region;
a first polarizer that aligns a polarization direction of light transmitted through the first pupil region, the second pupil region, and the third 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 different from the first polarization direction and the second polarization direction in the light which has been transmitted through the third pupil region and has been aligned in the first polarization direction;
an imaging element that receives the light transmitted through the first pupil region, the second pupil region, and the third pupil region and has a plurality of pixel units each of which is a set of a first pixel, a second pixel, and a third 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, the second pixel, and the third pixel and generates a first image corresponding to the light transmitted through the first pupil region, a second image corresponding to the light transmitted through the second pupil region, and a third image corresponding to the light transmitted through the third pupil region on the basis of the pixel signals subjected to the crosstalk removal process.
