Field: Audio-visual technology (Electrical engineering)
Classification: CPC G  H | 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 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;
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.
