Claim:
1. An electronic device, comprising: a camera; and circuitry configured to: automatically execute exposures at a photographing range, with different focuses by the camera, the photographing range comprising at least a first region where a first subject is located and a second region where a second subject is located; and acquire first images generated by the exposures, and display a second image on a display based on the first images, wherein the circuitry is further configured to: divide the first image of the photographing range captured for the first time by the camera into blocks and analyze sharpness of each of the blocks; acquire, if the sharpness of at least one of the blocks is less than a predetermined threshold value, the other first image of the photographing range with the focus on a region corresponding to a block which has the lowest sharpness; and generate the second image by synthesizing a block image of the first image which is acquired for the first time and has sharpness greater than or equal to the predetermined threshold value, and a block image of the other first image which is acquired from the second time and onward and has sharpness greater than or equal to the predetermined threshold value.
