摘要： A wearable terminal is constantly worn by a user and continually picks up images and sounds from the surroundings. Even when using a directional microphone to sensitively pick up targeted audio, the wearable terminal can reduce noise occurring due to motion of the device, for example when the user is walking, and reduce the influence of a shift of the sound pickup direction. For this purpose, the wearable terminal includes a sensor for detecting motion, and performs microphone directivity control to use the directional microphone when the amount of motion is small, and to use an omnidirectional microphone that is not likely to be influenced by noise when the amount of motion is large.

摘要： A sound collection apparatus includes a target sound collection unit that collects a sound including a target sound and outputs a collected-sound signal, a non-target sound collection unit, provided at positions different from each other, forms dead zones of sensitivity in a direction of the target sound source so as to collect a sound outside the dead zones and outputs a collected-sound signal. A sensitivity suppression unit generates a sensitivity suppression signal for suppressing a sound collection sensitivity in an overlap region in which dead zones overlap, as compared to a region surrounding the overlap region, by subjecting, to a predetermined signal processing, the collected-sound signal outputted by the non-target sound collection unit. An extraction unit removes, from the collected-sound signal, the sensitivity suppression signal generated, so as to extract a signal of a sound generated in the overlap region in which the dead zones overlap.
