Imaging apparatus

An imaging apparatus, comprising:

• a lens on which light from at least one subject is incident;
• a spectral prism including a first surface and a second surface, the first surface reflecting, at a first reflectance, first light having a first wavelength among the light from the subject, the second surface reflecting, at a second reflectance, second light having a second wavelength among light transmitted through the first surface;
• a first imaging unit that captures a first image of the subject at a first depth of field based on at least the first light reflected by the first surface;
• a second imaging unit that captures a second image of the subject at a second depth of field based on at least the second light reflected by the second surface;
• a third imaging unit that captures a third image of the subject at a third depth of field based on at least third light transmitted through the first surface or the second surface;
• and
• a signal processing unit that synthesizes the first image, the second image, and the third image, and outputs a synthesized image,
• wherein the first depth of field, the second depth of field, and the third depth of field are spatially and discontinuously provided.

• at least one processor that:
• synthesizes the first image, the second image, and the third image, and outputs a synthesized image;
• and
• generates a control signal of a depth of field based on distance information to the subject;
• and
• a driver that moves at least one of the first imaging unit, the second imaging unit, or the third imaging unit in optical axis directions thereof based on the control signal, wherein the first depth of field, the second depth of field, and the third depth of field are spatially and discontinuously provided.
