An image processing device (1) selects an image (60) in which sharpness of a photographic subject (61, 65) is relatively high compared with sharpness of a background. The image processing device (1) includes a photographic subject detection unit (22) that identifies a photographic subject region (62, 66) on an image (60), which includes a predetermined photographic subject (61, 65), by detecting the predetermined photographic subject (61, 65) from the image (60), a background region identifying unit (23) that identifies a background region (63, 67) on the image, which is other than the photographic subject region (62, 66), a sharpness identifying unit (24) that identifies sharpness of the photographic subject region (62, 66) and sharpness of the background region (63, 67), a score calculation unit (25) that calculates a score based on a difference in the sharpness between the photographic subject region (62, 66) and the background region (63, 67), and a determination unit (26) which determines the image (60) as an optimum image when the score indicates that photographic subject region (62, 66) is clearer than the background region (63, 67). |
