<P>PROBLEM TO BE SOLVED: To solve the problem of the conventional technique, in which the position of a sound source (lip) may not be estimated due to differences in hair colors and the like. <P>SOLUTION: An information processing device relating to the present invention for solving the problem described above, acquires a distance image indicating the distance between an object existing in a three-dimensional area and a plane to be a reference, specifies a first position in the area where the distance becomes an extremum based on the distance image, specifies a second position separated by a predetermined distance in the direction to the object from the first position, and determines the position of a sound source based on the second position. <P>COPYRIGHT: (C)2012,JPO&INPIT |
