Abstract
An information generation unitacquires, from a polarization imaging unit, observation values in which polarization directions are at least three or more directions (m≥3). A noise amount calculation unit-calculates an amount of noise on the basis of an observation value in a first polarization direction. Similarly, noise amount calculation units-to-calculate amounts of noise on the basis of observation values in second to m-th polarization directions. A polarization model estimation unitestimates a polarization model by using the observation values for the respective polarization directions and the amounts of noise calculated by the noise amount calculation units-to-. Thus, it is possible to calculate a polarization model that is robust against noise.
