Abstract:
A sound and video processing system includes: a display that displays a video image captured by the camera; a sound collector that collects sound; an input device that receives designation of at least one designated location in the video image displayed on the display. A processor generates emphasized audio data, in which sound is emphasized in at least one direction from a position of the sound collector toward at least one position corresponding to the at least one designated location. The processor displays at least one identification shape at the at least one designated location. In response to receiving re-designation of one of the at least one designated location by the input device, the processor outputs audio data in which emphasis of sound stops in a direction from the position of the sound collector toward the position corresponding to the re-designated location.
Abstract:
A directivity control method is provided for controlling a directivity of a sound collected by a first sound collector including a plurality of microphones. The directivity control method includes: forming a directivity of the sound in a direction toward a monitoring target corresponding to a first designated position in an image displayed on a display; obtaining information on a second designated position in the image displayed on the display, designated in accordance with a movement of the monitoring target, and changing the directivity of the sound toward the monitoring target corresponding to the second designated position by referring to the information on the second designated position.
Abstract:
An audio processing system, includes: an audio collector that collects audio in a non-directivity state using audio collection elements; an operator receives an input of one or more designation directions for audio emphasis for switching from the non-directivity state to a directivity state; an emphasis processor that generates audio data in the directivity state obtained by performing an emphasis process on the audio data in the designation direction from the audio collector using audio data collected by the audio collector according to the input of the designation direction; a volume adjustor that adjusts volume of the audio data in a directivity state; and an audio output that outputs the audio in a non-directivity state collected by the audio collector or the audio in a directivity state after the volume has been adjusted by the volume adjustor.
Abstract:
A directivity control apparatus controls a directivity of a sound collected by a first sound collecting unit including a plurality of microphones. The directivity control apparatus includes a directivity forming unit, configured to form a directivity of the sound in a direction toward a monitoring target corresponding to a first designated position in an image displayed on a display unit, and an information obtaining unit, configured to obtain information on a second designated position in the image displayed on the display unit, designated in accordance with a movement of the monitoring target. The directivity forming unit is configured to change the directivity of the sound toward the monitoring target corresponding to the second designated position by referring to the information on the second designated position obtained by the information obtaining unit.
Abstract:
A directivity control apparatus is provided which controls a directivity of a sound collected by a first sound collector including a plurality of microphones. The directivity control apparatus forms a directivity of the sound in a direction toward a position of a monitoring target in an image displayed on a display. Information on the position of the monitoring target in the image displayed on the display is obtained. The directivity of the sound is changed toward the position of the monitoring target in accordance with a movement of the monitoring target by referring to the obtained information on the position of the monitoring target.
Abstract:
A sound and video processing system includes: a display, having a rectangular display region, that displays a video image in a circular video-image display region smaller than the rectangular display region; and a sound collector that collects sound. A processor generates emphasized audio data, in which sound is emphasized in at least one direction from a position of the sound collector toward at least one position corresponding to at least one designated location in the video image. In response to receiving designation outside the video-image display region, the processor displays a state display area or an adjustment operation area for the sound to be output from the speaker in a rectangular region which has a diagonal line extending from one of four corners of the rectangular display region to a center of the video-image display region and intersecting with a boundary line of the video-image display region.

Abstract:
Sound collection directionality is formed toward a location corresponding to a position designated in a video of a predetermined region which is imaged by a camera apparatus with a microphone array apparatus as a reference, and audio data is collected with high accuracy. In a directionality control system (10), a signal processing unit (33) derives a sound collection direction (θMAh,θMAv) which is directed from an installation position of a microphone array apparatus (2) toward a sound position corresponding to a position designated in video data on a screen of the display device (36) in response to a user's designation of any position in the video data displayed on the screen. The signal processing unit (33) forms sound collection directionality of audio data in the derived sound collection direction (θMAh,θMAv).
Abstract:
A failure detection system includes an omnidirectional microphone array device having a plurality of microphone elements and a directivity control device that calculates a delay time of a voice propagated from a sound source to each microphone element and forms a directivity of the voice using the delay time and the voice collected by the omnidirectional microphone array device, and detects a failure of the microphone element. A smoothing unit calculates an average power of one microphone element. An average calculator calculates a total average power of a plurality of usable microphone elements included in the omnidirectional microphone array device. A comparison unit compares whether or not a difference between the average power and the total average power exceeds a range of ±6 dB, and determines whether the microphone element is in failure based on the comparison result.
Abstract:
In a directionality control system, a camera device captures a video of image capture area (SA). A microphone array device collects a sound in image capture area (SA). A signal processing section detects a sound source of the sound in image capture area (SA) which is collected by the microphone array device. In a case where the detected sound source is within a range of privacy area (PRA), an output control section controls the sound in image capture area (SA) which is collected by the microphone array device and is output from speaker device (37).
