Abstract: 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.

Abstract: An object of the present invention is to provide a portable electronic device of which operability is improved while maintaining a security function, and to provide a control method and a control program for the portable electronic device. In a case in which a function setting operation key is operated, a function limiting unit displays a screen for requesting password (for example, a personal identification number, a password, etc.) on a display unit, and limits utilization of a function assigned to the function setting operation key (for example, a variety of setting, an address book function, an electronic mail function, etc.).
