Abstract: A recorder receives designation of a video which is desired to be reproduced from a user. If designation of one or more designated locations where sound is emphasized on a screen of a display which displays the video is received by the recorder from the user via an operation unit during reproduction or temporary stopping of the video, a signal processing unit performs an emphasis process on audio data, that is, the signal processing unit emphasizes audio data in directions directed toward positions corresponding to the designated locations from a microphone array by using audio data recorded in the recorder. A reproducing device reproduces the emphasis-processed audio data and video data in synchronization with each other.

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: A system includes an imaging part that captures an image, a sound collection part that collects sounds, a display part that displays image data captured by the imaging part, a directive direction calculation part that calculates a directive direction which directs toward a sound position corresponding to a designated position of the image data from the sound collection part when any position of the displayed image data is designated, and a control part that forms a directivity in the sounds in the calculated directive direction. The control part controls output of the sounds collected by the sound collection part or output of the sounds which are collected by the sound collection part and of which the directivity is formed, or suspends collection of sounds in the sound collection part, when it is determined that the sound position is included in a preset protection 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).
