IMAGING DEVICE AND IMAGING METHOD

摘要

Provided is an imaging device including: a lens optical system L including at least an optical plane area D1 and an optical plane area D2, the optical plane area D2 having an optical property that causes a focusing property of the optical plane area D2 to differ from a focusing property of the optical plane area D1 due to a light beam that has passed through the optical plane area D1; an imaging element N including at least a plurality of pixels P1 and a plurality of pixels P2 which allow light that has passed through the lens optical system L to enter; and an array-shaped optical element K that is arranged between the lens optical system L and the imaging element N and is configured to cause light that has passed through the optical plane area D1 to enter the plurality of pixels P1 and to cause light that has passed hrough the optical plane area D2 to enter the plurality of pixels P2.
