Imaging apparatus

An imaging apparatus comprising:

• an imaging optical system;
• an image sensor having a plurality of light receiving elements two-dimensionally arranged therein;
• a light shielding member disposed between the imaging optical system and the image sensor, the light shielding member configured to make only a light flux, which has passed through a predetermined area of the imaging optical system, incident on a first light receiving element which is a part of the plurality of light receiving elements;
• and
• an image generation device configured to generate an image of a subject from an imaging signal of the first light receiving element,
• wherein the light shielding member is a plate-shaped member having a first light shielding material formed to correspond to the first light receiving element and formed to shield a light flux, which has passed through an area other than the predetermined area, formed therein,
• wherein the imaging optical system includes a first area having a first characteristic and a second area having a second characteristic different from the first characteristic, the second area being wider than the first area,
• only the light flux, which has passed through the first area, is incident on the first light receiving element by the light shielding member,
• light fluxes, which have respectively passed through the first area and the second area, are incident on a second light receiving element other than the first light receiving element,
• the image generation device generates an image of the subject from an imaging signal of the second light receiving element, and
• the imaging apparatus includes an image processing unit configured to perform at least one of blur correction processing, contrast correction processing, and interpolation processing of embedding a missing pixel when the image of the subject is generated from the imaging signal of the second light receiving element.
