Abstract:
1. A polarization color image capture device comprising: a polarization color filter plate including a first area configured to transmit light that is polarized in a first direction and that falls within a first wavelength range, a second area configured to transmit light that is polarized in a second direction and that falls within a second wavelength range, and a third area configured to transmit incoming light at least partially; an image sensor in which a plurality of unit blocks, each including first, second and third photosensitive cells and first, second and third polarization filters that are arranged to face the first, second and third photosensitive cells, respectively, are arranged on an imaging area, the polarization transmission axis directions of the first, second and third polarization filters being different from each other; an optical lens that produces an image on the imaging area of the image sensor; a signal processing section that processes a signal supplied from the image sensor; a drive mechanism that is able to insert and remove the polarization color filter plate onto/from an optical path; and a control section that controls the drive mechanism and the image sensor so that a first image capturing session is performed with the polarization color filter plate removed from the optical path and that a second image capturing session is performed with the polarization color filter plate inserted onto the optical path.
