METHOD AND APPARATUS FOR REPRODUCING THREE-DIMENSIONAL SOUND

摘要

Stereophonic sound is reproduced by acquiring image depth information indicating a distance between at least one object in an image signal and a reference location, acquiring sound depth information indicating a distance between at least one sound object in a sound signal and a reference location based on the image depth information, and providing sound perspective to the at least one sound object based on the sound depth information.

主权项

1. A method of reproducing stereophonic sound, the method comprising:
acquiring image depth information from a depth map representing depth values of pixels that constitute an image object in an image signal; acquiring sound depth information indicating a distance between at least one sound object in a sound signal and a reference location, using representative depth values for each image section that constitutes the image signal or a depth value of the image object in the image signal; and providing sound perspective to the at least one sound object based on the sound depth information, wherein the image depth information indicates a distance between at least one image object in the image signal and the reference location.
