A depth map generation unit 22 generates a depth map that generates the depth map from images obtained by picking up a subject at a plurality of viewpoint positions by an image pickup unit 21. On the basis of the depth map generated by the depth map generation unit 22, an alignment unit 23 aligns polarized images obtained by the image pickup unit 21 picking up the subject at the plurality of viewpoint positions through polarizing filters in different polarization directions at the different viewpoint positions. A polarization characteristic acquisition unit 24 acquires a polarization characteristic of the subject from a desired viewpoint position by using the polarized images aligned by the alignment unit 23 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.

A double-layered liquid crystal lens in which two liquid crystal layers are disposed, and a 3D display apparatus. In a 3D display mode, under control of an electric field, liquid crystal molecules of a first liquid crystal layer are deflected to form a plurality of first lenticular lens structures. In case of switching from the 3D display mode into a 2D display mode, under the control of an electric field, liquid crystal molecules in a second liquid crystal layer are deflected to form a plurality of second lenticular lens structures; the second lenticular lens structures are mirror symmetric to the corresponding first lenticular lens structures, so as to compensate a phase delay of a light modulated by the first lenticular lens structures, such that the light passes through the double-layered liquid crystal lens without deflection, and thus a normal 2D display state is realized.
