Japanese Patent JP7326581

B2

Provided are an imaging apparatus and a method capable of capturing a high-quality multi spectral image. The imaging apparatus includes: an optical system that has three or more aperture regions at a pupil position or near the pupil position, each of the aperture regions being provided with a different combination of a polarizing filter and a bandpass filter such that the aperture region transmits light having a combination of a different polarization angle and a different wavelength range; an image sensor in which three or more types of pixels that receive light having different polarization angles are arranged two-dimensionally; and a processor that performs interference removal processing on a signal output from the image sensor and generates an image signal for each of the aperture regions. In a case where the optical system has three or more types of the polarizing filters and the polarizing filters are arranged in an order of the polarization angles, at least one of differences in the polarization angles of the adjacent polarizing filters is different from the others.
