Sound is outputted, without giving the sense of incongruity to the user, even if reproduction of animation is stopped by the user. An animation acquiring section 11 acquires animation data D1 representing an animation generated in advance based on a setting operation by the user, and sound data D2 representing a sound to be reproduced in association with the animation. A sound output control section 12 calculates stop time sound information representing a feature of the sound at a point of time at which reproduction of the animation is stopped, using sound attribute information D4, in response to input of a stop command by the user, and determines a predetermined output method of the sound that matches the animation, based on the calculated stop time sound information, to reproduce the sound by the determined output method.
