IMAGING APPARATUS AND IMAGING MODULE
First Claim
1. An imaging apparatus comprising:
- a pattern mask in which a transmissive region transmitting incident light and a light shielding region shielding incident light are arranged;
a directional sensor that has a light receiving surface close to which the pattern mask is provided, receives a projection image of the pattern mask with light from a subject through the pattern mask, divides the light incident on the pattern mask from the subject into a plurality of azimuthal regions with different directions, and acquires a plurality of the projection images corresponding to the plurality of divided azimuthal regions; and
a restored image generation unit that restores and generates a plurality of images of the subject corresponding to the plurality of azimuthal regions from the plurality of acquired projection images.

Abstract
The present invention provides an imaging apparatus that individually obtains high image quality, restored images for a plurality of different directions at a wide angle of view without using a lens, and an imaging module using such an imaging apparatus. In an imaging apparatus according to an aspect of the invention, incident light is divided into a plurality of azimuthal regions by a directional sensor, and images corresponding to the azimuthal regions are restored from a plurality of projection images acquired corresponding to the azimuthal regions. Accordingly, incident light from oblique directions does not become noise to incident light from a front direction, and projection images can be individually acquired for the azimuthal regions throughout a wide range from the front direction to the oblique directions. For this reason, restoration processing according to properties of a pattern mask and the projection images is executed, whereby it is possible to individually obtain high image quality restored image for a plurality of different directions (azimuthal regions) at a wide angle of view without using a lens.
