Abstract
There is provided an imaging device including: an imaging section including pixels that generate pixel signals on the basis of incident light, the pixels including a polarization pixel having a predetermined polarization direction and a non-polarization pixel; and a polarization rotating section provided on an incidence plane side of the imaging section, and configured to rotate a polarization direction of the incident light.
Claims20
An imaging device comprising:
- an imager including
- a plurality of first pixels arranged in an array, respective ones of the plurality of first pixels including a polarizing filter having a predetermined polarization direction with respect to a plane of the array, and
- a plurality of second pixels, respective ones of the plurality of second pixels not including any polarizing filter;
- a polarizing element provided on an incidence plane side of the imager;
- and
- control circuitry configured to detect a change in a polarization direction of intermediate light between the imager and the polarizing element, in a case where the polarizing element is rotated with respect to the imager.

An imaging method comprising:
- making incident light be incident on an imager including a plurality of first pixels arranged in an array and a plurality of second pixels by first passing through a polarizing element;
- and
- detecting a change in a polarization direction of intermediate light between the imager and the polarizing element, in a case where the polarizing element is rotated with respect to the array, wherein
- respective ones of the plurality of first pixels include a linear polarizing filter having a predetermined polarization direction with respect to a plane of the imager, and
