Patent ID: 7336792

Claim:
An acoustic image localization processing device for synthesizing acoustic signals to match an image signal reproduced from a video disc using an angle mode selected by a viewer, comprising: a decoder for decoding a reproduction signal reproduced from said video disc in accordance with the selected angle mode and for outputting an angle selection signal corresponding to the selected angle mode; said reproduction signal including the image signal corresponding to the angle mode, an audio signal having a plurality of channels, and a sound source signal indicating a position of at least one sound source within the audio signal; and modification means for modifying said audio signal using the angle selection signal to correspond to the selected angle mode, thereby matching the image signal corresponding to the selected angle mode; the modification means including: localization information modification means for applying modifications to acoustic image localization information indicating one of a predetermined reproduction acoustic image localization position and a direction with respect to the sound source signal and for providing new acoustic image information; and acoustic image localization processing means for performing processing to modify one of the reproduction acoustic image localization position and the direction, based on the acoustic image localization information provided by said localization information modification means with respect to said sound source signal.
