Electronic device, photographing control method, photographing control program, and integrated circuit

Abstract

An electronic device can perform photographing by an AF (Auto-Focusing) function and a PF (Pan-Focus) function, and can give improvement of quickness of the taking of an image by automatically selecting an image, which is taken into the device, from a relation between the AF function and a shutter operation. The electronic device has an imaging part which catches an image obtained through an optical system, and also has a focusing mechanism which moves the optical system to an auto-focusing position or a fixed focus position. The electronic device further comprises a switch and a control part. The switch functions as a focusing switch ordering the focusing mechanism a focusing action, and also functions as a shutter switch ordering taking of an image caught by the imaging part. By this, the switch orders the focusing action or the taking of the caught image. The control part, in the case in which the shutter operation of the switch is performed during the focusing action of the focusing mechanism due to the switch, switches the optical system to the fixed focus position from auto-focusing position, and takes a fixed focus image.
