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.
