In step S211, the system control unit 50 determines whether or not the power source unit 30 has capacity sufficient for recording one movie corresponding to one chapter, and the recording medium 200 has capacity sufficient for recording one chapter. In short, the system control unit 50 determines whether or not a movie corresponding to one chapter can be recorded. If the system control unit 50 determines that a movie corresponding to one chapter can be recorded (YES in step S211), the processing proceeds to step S216. If the system control unit 50 determines that a movie corresponding to one chapter cannot be recorded (NO in step S211), the processing proceeds to step S212. It is only required that the power source unit 30 has battery capacity sufficient for recording one movie corresponding to one chapter, and the recording medium 200 has capacity sufficient for recording a movie corresponding to one chapter with an effect. In the present exemplary embodiment, a recording time for recording a movie corresponding to one chapter is not fixed, and is selected from among 3, 4, and 6 seconds. Thus, in this step, the system control unit 50 determines whether or not the power source unit 30 has battery capacity sufficient for 6-second movie recording and processing of applying an effect thereto. In the present exemplary embodiment, the maximum length of a recording time of a movie to be recorded as one chapter is 6 seconds. It is therefore determined that the battery capacity corresponding to 6 seconds is sufficient for any of recording times that are to be possibly set.
