<P>PROBLEM TO BE SOLVED: To provide a configuration of a presence signal generating apparatus for generating a stereophonic sound field signal obtained when a listener listens to a sound emitted from a plurality of objects stuck to a display menu at a virtual listening position set in the display menu. <P>SOLUTION: The configuration of the presence signal generating apparatus is realized by defining X, Y coordinates with a listening position on the display menu as the origin, obtaining arrangement information of the displayed image objects by a management table generating means 13, obtaining a localization direction of a sound object sounded from the image objects on the basis of the arrangement information by an arrival direction arithmetic means 16, obtaining a head transfer function of the sound object with respect to its localization direction from a storage section 14, and generating the stereophonic sound field signal related to the objects through convolution calculation at a convolution means 15. <P>COPYRIGHT: (C)2004,JPO |
