Patent ID: 8885070

Claim:
An imaging apparatus comprising: an imaging unit for acquiring a plurality of viewpoint images imaged from a plurality of viewpoints by a plurality of imaging optical systems each including a zoom lens; a storage unit for storing a parallax corresponding to a distance to a subject of each viewpoint image acquired by each imaging optical system; an optical zoom magnification specifying unit for receiving a specification instruction of an optical zoom magnification; a zoom lens driving unit for moving the zoom lens to a position corresponding to the instruction of the optical zoom magnification received by the optical zoom magnification specifying unit; a distance measuring unit for measuring a distance to a subject; a determination unit for determining whether or not compensation for expansion of the parallax by changing the optical zoom magnification is possible to create a three-dimensional image, based on the distance to the subject; and a correction unit for setting an electronic zoom magnification corresponding to the distance to the subject measured by the distance measuring unit and the position of the zoom lens moved by the zoom lens driving unit, extracting a range for securing the parallax stored in the storage unit from the viewpoint images, and magnifying the extracted range based on the electronic zoom magnification if the determination unit determines that the compensation for expansion of the parallax is possible.
