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 recording device records a video and an imaging time, and a voice. Based on the voice, a sound parameter calculator calculates a sound parameter for specifying magnitude of the voice in a monitoring area at the imaging time for each of pixels and for each of certain times. A sound parameter storage unit stores the sound parameter. A sound parameter display controller superimposes a voice heat map on a captured image of the monitoring area and displays the superimposed image on a monitor. At this time, the sound parameter display controller displays the voice heat map based on a cumulative time value of magnitude of the voice, according to designation of a time range.

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 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.
