Abstract:
An image and sound reproduction system comprising:a still picture synthesizer that combines at least one arbitrary first still picture with plural second still pictures serving as a background; and a synthesis and reproduction controller that, in accordance with position information for combining the first still picture with the second still pictures or selection information for selecting one from the at least one arbitrary first still picture, controls said still picture synthesizer so as to combine the first still picture with the second still pictures, and sequentially reproduce synthetic images, wherein: said system further comprises a user object extractor that sets a partial region (hereinafter, referred to as first dummy object) of a dummy still picture serving as a reference, and for extracting a part (hereinafter, referred to as user object) of the first still picture corresponding to arbitrary position coordinates of the first dummy object; an edge detector that detects an edge of the user object extracted by said user object extractor; and a corrector that calculates position correction information which correlates arbitrary pixel coordinates of the edge detected by said edge detector with pixel coordinates of the first dummy object corresponding to the arbitrary pixel coordinates, and that corrects the position information on the basis of the position correction information.
