Image sensing apparatus with selectably combinable microphone signals to obtain desired directivity
Abstract:
Provided is an image sensing apparatus in which directivity can be changed in accordance with the position of the shooter. The image sensing apparatus includes a video shooting unit, at least four microphones placed around the video shooting unit, and an audio signal processing unit adapted to synthesize audio signals from two microphones among the at least four microphones, thereby outputting a synthesized audio signal from a specific direction of the video shooting unit. The apparatus further includes a selecting unit adapted to select the position of a shooter. The audio signal processing unit includes a directivity changeover unit adapted to change over directivity by changing a combination of the two microphones in accordance with a selection output signal the said selecting unit.
