Furthermore, the description has been given of a case in which the number of chapters included in a set of movies is preset. Alternatively, the number of chapters may be changed according to the motion of an object and the change in color temperature or brightness. For example, in response to it being determining that there is little change in the motion of an object when, among a plurality of recorded chapters, the chapters are compared with each other, the recording may be stopped so as not to continue the recording any more. In addition, in a case in which the change of an object increases as the recording progresses, and it is determined that increasing the number of chapters results in the creation of a set of movies more interesting for the user, the number of chapters to be recorded may be increased.
