Processing of performing an image analysis on a second motion picture to set, as an analysis result, a position of a second subject appearing in the second motion picture, and on the basis of the analysis result, adjusting, as a compositing condition, a composited position at which a first motion picture is composited into the second motion picture avoiding a first subject from overlapping the second subject is performed. Moreover, processing of setting, as an analysis result, a face size of a first person appearing in the first motion picture as the first subject and a face size of a second person appearing in the second motion picture as the second subject.
