Abstract
An imaging apparatus includes a lens on which light from one subject is incident, a spectral prism including a first surface reflecting, at a first reflectance, first light having a first wavelength, and a second surface reflecting, at a second reflectance, having a second wavelength, a first imaging unit capturing a first image of the subject at a first depth of field based on the first light reflected by the first surface, a second imaging unit capturing a second image of the subject at a second depth of field based on the second light reflected by the second surface, a third imaging unit capturing a third image of the subject at a third depth of field based on third light transmitted through the first surface or the second surface, and a signal processing unit synthesizing the first image, the second image, and the third image, and outputting the synthesized image.
