A photographing apparatus comprises an imaging sensor, a power supply controller, and a moving-picture generator. The imaging sensor continuously performs imaging operations in a predetermined interval. The power supply control unit controls power supply to the imaging sensor during a waiting period that is defined as a period from the end of one imaging operation of the imaging operations to the beginning of the next imaging operation of the imaging operations. The moving-picture generator generates a moving-picture file by incorporating a plurality of still pictures, obtained by the imaging operations, into a frame composing a moving picture.
