Title:
IMAGING APPARATUS AND ELECTRONIC SYSTEM
Document Type and Number:
WIPO Patent Application WO/2013/161216
Kind Code:
A1
Abstract:
An imaging apparatus includes: a lens group formed of one or more lens elements; and an imaging device having a light receiving surface on which the lens group forms an image of an object, wherein the light receiving surface of the imaging device is a curved surface that is concave toward the lens group, and the light receiving surface of the imaging device has an aspheric shape so shaped that a tangential angle that is an angle between a tangential line circumscribing an edge of the light receiving surface and a plane perpendicular to an optical axis of the lens group is smaller than the tangential angle provided when the light receiving surface has a spherical shape.
