Patent ID: 6985854

Claim:
An information processing device comprising: sound signal obtaining means for obtaining a sound signal; sound signal analyzing means for frequency-analyzing said obtained sound signal; frequency-analyzed picture producing means for producing a specified frequency-analyzed picture on the basis of a result of said frequency-analysis; first judging means for judging whether or not a level of a first frequency band is above a first predetermined threshold value; selected picture switching means that switches and selects one among a plurality of registered pictures as a selected picture on the basis of said level of said first frequency band of the analyzed sound signal from said sound signal analyzing means, when said first judging means judges that said level of said first frequency band is above said first predetermined threshold value; second judging means for judging whether or not a level of a second frequency band is below a second predetermined threshold value; composed picture display means that displays a composed picture produced by composing said frequency-analyzed picture and said selected picture, when said second judging means judges that said level of said second frequency band is below said second predetermined threshold value; and for changing means for changing a composing process of said frequency analyzed picture and said selected picture on the basis of said level of said second frequency band of the analyzed sound signal from said sound signal analyzing means, when said second Judging means judges that said level of said second frequency band is above said second predetermined threshold value.
