<P>PROBLEM TO BE SOLVED: To obtain an acoustic effect with a rich atmosphere by increasing an acoustic sense of presence even when only a monaural microphone can be mounted. <P>SOLUTION: A face detector 7 detects the face of a subject from an image imaged by an imaging unit 6. After identifying the position of the subject face in the imaged image as a sound source position, a controller 1 obtains pseudo stereo from a monaural sound, collected by a sound collector 9 through a monaural microphone 8, according to the identified sound source position. To obtain the pseudo stereo, a sound volume difference between left and right channels is adjusted to be fit to the ratio of the sound source position from the left and right ends of a screen. <P>COPYRIGHT: (C)2012,JPO&INPIT |
