Abstract: There is provided a collation device capable of capturing a face image suitable for collation by an imaging device while making a display suitable for collation by a display to a person in the front side of a half mirror. By disposing a plurality of displays with predetermined gap in the back side of the half mirror and disposing camera lenses and in this gap, it is possible to make the line of sight for viewing the display and the line of sight for imaging by the cameras be almost the same. As a result, it is possible to capture a face image suitable for collation by an imaging device while making a display suitable for collation by a display to a person in the front side of the half mirror.

Abstract: In a sound source display system, an omnidirectional camera captures an image of a monitoring area. A microphone array collects a voice in the monitoring area. A monitoring monitor displays the image of an imaging area captured by the omnidirectional camera. A sound pressure calculator in a directivity control device calculates a sound pressure indicating a source of a sound in the image of the imaging area using voice data of the voice collected by the microphone array. An output controller in the directivity control device compares the sound pressure and threshold values (first threshold value, second threshold value), and causes sound image information in which the sound pressure is converted into visual information according to the result of comparison, to be displayed on the monitoring monitor so as to be superimposed on the image of the imaging area.

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 directionality control system includes: a camera; a microphone provided as a separate body from the camera; a display that displays video data captured by the camera; and a processor that computes a sound collection direction, which is directed from the microphone toward a sound position corresponding to a designated position in the video data. The processor computes the sound collection direction by using parameters including: a first height of the camera from a reference surface, a second height of the microphone from the reference surface, a third height of a computation reference point from the reference surface, the computation reference point being positioned in the sound collection direction at a position different from the sound position, a direction which is directed from the camera toward the sound position, and a fourth height of the sound position from the reference surface.

Abstract: When a microphone array apparatus sound-picks up voice in a prescribed sound volume or higher, which is output from a sound source, and sends voice data on the voice to voice processing apparatus, a sound source direction detection unit causes sound source marks, each of which indicates a directivity direction, to be displayed on a display, and urges a user to make a selection among the sound source marks and to input camera information. A voice processing apparatus transmits the camera information that is input, and the directivity direction, to the microphone array apparatus. The microphone array apparatus stores the camera information and the directivity direction, as a preset information table, in a storage unit. Accordingly, where a positional relationship between the camera and the microphone array is unclear, directionality is formed in a determined image capture position, and voice in the predetermined image capture position is output clearly.

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.
