ELECTRONIC DEVICE, METHOD, AND PROGRAM

An electronic device according to a first aspect comprises an imaging device and a processor. The imaging device has a predetermined imaging region, and is configured to capture images having different focal distances. The processor is configured to execute a first process of identifying two or more focus identification regions included in a first imaging region included in the predetermined imaging region by comparing the captured images in the first imaging region, and a second process of interpolating a focal distance of a middle region not belonging to the two or more focus identification regions in the first imaging region. The second process includes a process of interpolating the focal distance of the middle region based on a focal distance of an interpolation focus region that is located inside or outside the middle region and that is one of the two or more focus identification regions.
