In addition, the description has been given of a case in which an effect to be applied to each movie is determined irrespective of the user's intention, before recording the movie. Alternatively, the effect may be automatically determined according to a predetermined condition that is based on an object and the content of a movie that are intended by the user. Yet alternatively, the effect may be freely-determinable by the user. In addition, instead of being automatically selected from among 3, 4, and 6 seconds, the candidate length of a recording time may be settable by the user, or another candidate length such as 5 and 8 seconds may be added. In addition, the description has been given of a case in which an effect is applied in such a manner that a reproduction time becomes 4 to 7 seconds. The reproduction time, however, is not limited to these times, and may be 10 or 20 seconds, or 2 or 3 seconds. The candidate reproduction times are not limited to those provided in the above-described example. In addition, the number of movies constituting a set of movies may not be four, and may be presettable by the user. In addition, the number of movies finally constituting a set of movies may not match the number of movies to be recorded. In other words, a set of movies may include recorded movies obtained by applying a plurality of different effects to one recorded movie, or recorded movies obtained by applying an effect to one movie, and by applying no effect to the one movie.
