Abstract
A method and apparatus for controlling illumination of a monitored area, by detecting sound (202) originating from an area to be monitored, and analysing the sound to recognise one or more target sounds (222) corresponding to unwanted behaviours such as offensive shouting, chanting or singing. The location of target sounds is determined (224) based on the received sound, and the determined location is exposed to adverse lighting (212), such as over or under exposure, or flickering or flashing effects, which are irritating or uncomfortable.
Claims15
A lighting control method comprising:
- detecting sound originating from an area to be monitored;
- analysing the detected sound to recognise one or more target sounds indicative of a behaviour comprising at least one of shouting, chanting and singing of one or more subjects in said area
- determining, based on the detected sound, the location of the source of the target sounds in the monitored area;
- determining a rhythm of the detected sound;
- and
- controlling one or more luminaires to expose the determined location to a lighting effect, asynchronous to the determined rhythm, to modify said behaviour.
A lighting control apparatus for controlling illumination of a monitored area, said apparatus comprising:
- an input adapted to receive audio data representative of sound originating from an area to be monitored;
- a sound recognition module adapted to process the received audio data in order to recognise one or more target sounds indicative of a behaviour comprising at least one of shouting, chanting and singing of one or more subjects in said area;
- a sound source location module adapted to process the received audio data in order to determine the location of the source of recognised target sounds in the monitored area;
- determining a rhythm of the detected sound;
- and
- a lighting control module adapted to control one or more luminaires to expose the determined location to a lighting effect, asynchronous to the determined rhythm, to modify said behaviour.
