Acoustic presentation system and sound reproducing apparatus and method and computer-readable recording medium and acoustic presentation program.

摘要

PPROBLEM TO BE SOLVED: To easily obtain a reproduction sound field with high presence corresponding to a displayed image. PSOLUTION: A sound collection section 14 employing a super-directivity microphone or the like acquires sound supplied from an object side of a photographed image to produce an acoustic signal Sa. An imaging section 12 produces an image signal Sv. An information signal WS is produced on the basis of the signals Sa, Sv or the like to acquire sound. In the case of reproducing the sound, the signals Sa, Sv are separated from a signal RS. A presentation control section 50 moving a display position of the image and generating a display position signal PD generates a presentation adjustment signal CP on the basis of installation information CSa with respect to the number of acoustic output sections 60 and the installed position or the like and the signal PD. An acoustic output signal generating section 52 generates a plurality of acoustic output signals SAout on the basis of the signal CP and the signal Sa and controls the signal level or the like of the signal SAout to supply the result to a plurality of the acoustic output sections 60, which output sound corresponding to the display position of the image.
