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.

Abstract: To implement a configuration for enabling independent adjustment of a spatial resolution and a wavelength resolution of a spectroscopic measurement device. A spatial resolution adjustment unit configured to adjust a spatial resolution of the spectroscopic measurement device, and a wavelength resolution adjustment unit configured to adjust a wavelength resolution of the spectroscopic measurement device are included, and the spatial resolution adjustment unit maintains output light from a condensing unit to a spectroscopic imaging unit of the spectroscopic measurement device as parallel light, adjusts a parameter of a constituent element of the condensing unit, and changes the spatial resolution without changing the wavelength resolution of the spectroscopic measurement device. The wavelength resolution adjustment unit adjusts a parameter of a spectroscopic imaging unit of the spectroscopic measurement device and changes the wavelength resolution without changing the spatial resolution of the spectroscopic measurement device.

Abstract: A polarization imaging unit 20 acquires a polarization image using a lens. In a parameter storage unit 32 of an information processing unit 30, 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 33 of the information processing unit 30 corrects the change in polarization state due to the lens, using the parameters stored in advance in the parameter storage unit 32.

Abstract: A normal candidate information generation unit 31 of an information processor 30 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 20. The in-plane pixel selection unit 32 selects a plurality of pixels indicating the plane to be observed in the polarization image. A normal calculation unit 33 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 32. For example, the normal calculation unit 33 calculates the normal of the plane to be observed on the basis of a line-of-sight axis indicating a light beam direction from the plane to be observed corresponding to the pixels selected by the in-plane pixel selection unit 32 toward the polarization imaging unit 20 and the zenith angles of the selected pixels.
