摘要

PROBLEM TO BE SOLVED: To easily obtain a reproduction sound field with high presence.

SOLUTION: 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. A position detection section 16 detects a photographing direction and a distance up to the object to produce a position information signal Sp. An information signal WS is produced on the basis of the signals Sa, Sp to acquire sound. In reproducing the sound, the signals Sa, Sp are separated from a signal RS. A presentation control section 50 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 Sp. 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 and the phase of the signal SAout to supply the result to a plurality of the acoustic output sections 60, which output sound.
