Abstract: Provided is a polarization imaging unit that acquires a polarization image using a lens. In a parameter storage unit of an information processing unit, parameters related to a change in polarization state due to the lens which are estimated in advance from polarization state information acquired by imaging a light source in a predetermined polarization state using the lens and polarization state information indicating the polarization state of the light source, for example, change parameters indicating the change in polarization state due to the lens or correction parameters for correcting the change in polarization state due to the lens are stored. A polarization state correction unit of the information processing unit corrects the change in polarization state due to the lens, using the parameters stored in advance in the parameter storage unit.

Abstract: A correction information generation section 50 emits measurement light having uniform intensity onto a polarized image acquisition section 20 acquiring a polarized image. Further, on the basis of a measured polarized image acquired from the polarized image acquisition section 20, the correction information generation section 50 generates variation correction information for correcting sensitivity variations caused in the measured polarized image due to difference in polarization direction, and causes a correction information storage section 30 to store the generated variation correction information. A correction processing section 40 then corrects the sensitivity variations caused in the polarized image acquired by the polarized image acquisition section 20 due to the difference in polarization direction by using the pre-generated variation correction information stored in the correction information storage section 30. Therefore, the polarized image outputted from the correction processing section 40 becomes a high-quality polarized image with, for example, its sensitivity variations corrected.

Abstract: A normal candidate information generation unit of an information processor generates normal candidate information for each pixel indicating, for example, a zenith angle, or an azimuth angle, or a zenith angle and an azimuth angle, on the basis of a polarization image in a plurality of polarization directions obtained by a polarization imaging unit. The in-plane pixel selection unit selects a plurality of pixels indicating the plane to be observed in the polarization image. A normal calculation unit calculates a normal of the plane to be observed on the basis of the normal candidate information of the pixels selected by the in-plane pixel selection unit.

Abstract: An image processing device and a method that enable removal of reflection component light from images captured from various directions are provided. The image processing device includes: an image input unit that acquires at least three types of images formed with polarization images of different polarizing directions or non-polarization images; an angle input unit that outputs reflection angles that are the angles between the image capturing directions of the acquired images and the plane direction corresponding to the normal direction of the reflecting surface, to an intensity transmittance and intensity reflectance calculation unit; a calculation unit that calculates the respective intensity transmittances and the respective intensity reflectances of S waves and P waves, using the reflection angles; and a reflection component separation unit that removes the reflected light component from the images acquired by the image input unit, using the respective intensity transmittances and the respective intensity reflectances of the S waves and P waves. These processes enable removal of reflected light components from captured images having various reflection angles.
