Abstract
A depth map generation unit generates a depth map from images obtained by picking up a subject at a plurality of viewpoint positions by an image pickup unit. On the basis of the depth map generated by the depth map generation unit, an alignment unit aligns polarized images obtained by the image pickup unit picking up the subject at the plurality of viewpoint positions through polarizing filters in different polarization direction at the different viewpoint positions. A polarization characteristic acquisition unit acquires a polarization characteristic of the subject from a desired viewpoint position by using the polarized images aligned by the alignment unit to obtain the high-precision polarization characteristic with little degradation in temporal resolution and spatial resolution. It becomes possible to acquire the polarization characteristic of the subject at the desired viewpoint position.
