Patent number: 11425298Abstract: The present technology relates to an imaging device, an imaging method, and a program capable of setting a resolution based on a distance to a subject. A control unit which changes a resolution of a captured image on the basis of distance information, corresponding to the captured image, regarding a detected distance to a subject included in the image is included. The control unit changes a resolution of a portion of a region of the captured image on the basis of the distance information. The portion of the region is a region distant from another region.
