Imaging Device
First Claim
1. An imaging device comprising:
- a modulator with a first pantoscopic grating pattern, the modulator configured to modulate light intensity by passage through the first pantoscopic grating pattern;
an image sensor configured to convert light passing through the modulator, to image data, and output the image data; and
an image processing unit configured to conduct image processing of restoring an image with the use of the image data output from the image sensor,wherein the first pantoscopic grating pattern is configured to comprise multiple basic patterns, andeach of the basic patterns has the shape of a concentric circle.

4. The imaging device according to claim'"'"', wherein the modulator comprises a first polarization plate and a second polarization plate,
the first polarization plate is disposed closer to a surface configured to serve as an input face of the modulator, the second polarization plate is disposed closer to a rear surface configured to serve as an output face of the modulator, and the first polarization plate and the second polarization plate have polarizing axes determined on the basis of an arrangement of the basic patterns.
