Patent ID: 8605197

Claim:
An imaging apparatus, comprising: an image formation lens having focal lengths different in every region; a light receiving section having a plurality of light receiving elements; a plurality of optical elements respectively provided corresponding to a plurality of the light receiving elements to make the corresponding light receiving elements receive an object light beam that passed through predetermined pupil regions in an exit pupil of the image formation lens; and an image generation section adapted to generate an image of an object from imaging signals of a plurality of the light receiving elements, wherein a plurality of first optical elements out of the plurality of the optical elements make an object light beam, which passes through a region having a first focal length of the image formation lens and a first pupil region in the exit pupil, incident into the corresponding light receiving elements, a plurality of second optical elements out of the plurality of the optical elements make an object light beam, which passes through a region having a second focal length of the image formation lens and a second pupil region in the exit pupil, incident into the corresponding light receiving elements, and the image generation section selects, for generation of the image of the object, any one of the pupil regions in the exit pupil through which a light beam passes and generates the image of the object with use of imaging signals of a plurality of the light receiving elements that receive an object light beam that passed through the selected pupil region.
