Claim 11:
12. The directional sound capture controller of claim 8,
wherein the light source is at least one selected from a group consisting of a local light emitter attached to the sound source object and a reflective region of the sound source object emitting a sound source object-reflected light in response to a remote light emitter separate from the sound source object,
wherein the pattern of local light change across the sequence of images is produced by at least one selected from a group consisting of the local light emitter, the remote light emitter, and a geometric reflection pattern of the reflective region, and
