Imaging device, imaging method, and program

An imaging method in an imaging device including an imaging optical system that includes a first optical system and a second optical system having a common optical axis and having different focal lengths, an imaging element that includes a first sensor group selectively receiving light passing the first optical system and a second sensor group selectively receiving light passing the second optical system, and an image generating unit that generates a first generated image on the basis of a first captured image output from the first sensor group and generates a second generated image on the basis of a second captured image output from the second sensor group, the method comprising:

• in the image generating unit,
• a step of performing registration on a plurality of the first captured images captured in different states of the optical axis of the first optical system;
• a step of generating the first generated image by compositing the registrated plurality of first captured images;
• a step of performing registration on a plurality of the second captured images captured in different states of the optical axis of the second optical system;
• and
• a step of generating the second generated image by compositing the registrated plurality of second captured images.

A non-transitory computer readable recording medium storing a program that causes a computer to execute procedures of an imaging method in an imaging device including an imaging optical system that includes a first optical system and a second optical system having a common optical axis and having different focal lengths, an imaging element that includes a first sensor group selectively receiving light passing the first optical system and a second sensor group selectively receiving light passing the second optical system, and an image generating unit that generates a first generated image on the basis of a first captured image output from the first sensor group and generates a second generated image on the basis of a second captured image output from the second sensor group, the procedures comprising:

• in the image generating unit,
• a procedure of performing registration on a plurality of the first captured images captured in different states of the optical axis of the first optical system;
• a procedure of generating the first generated image by compositing the registrated plurality of first captured images;
• a procedure of performing registration on a plurality of the second captured images captured in different states of the optical axis of the second optical system;
• and
• a procedure of generating the second generated image by compositing the registrated plurality of second captured images.
