VIDEO DISPLAY HAVING AUDIO CONTROLLED BY VIEWING DIRECTION

摘要

A video processor is responsive to an output of a pair of cameras that are used for detetermining a viewer viewing direction of a display screen. Once the viewer's viewing angle crosses a threshold angular direction dynamically tracking pan function is enabled so as to shift the displayed picture. An enhanced audio processor makes the perceived sources of sound produce in speakers dynamically follow the shifted picture. As the displayed image shifts by the dynamically tracking pan function, the locations from which the sound is perceived to originate also track the displayed image so that the stereophonic width dynamically varies in accordance with the stereoscopic width.
