More Information
Summary:A presence detection system (10) is disclosed comprising a camera module (20) comprising an image sensor (21) having a plurality of pixels (22) for capturing an image of a space (1) and a signal processor (23) arranged to process signals from each pixels in accordance with one or more configuration parameters for said pixel; and generate a setting for the image sensor from the processed signals. The system further comprises a controller (30) communicatively coupled to the signal processor and arranged to provide the signal processor with configuration parameters for the pixels based on an expected presence in a region of said image such that the pixels corresponding to said region have at least one different configuration parameter to pixels outside said region; periodically receive the setting from the signal processor; and detect a change in said presence in the space from a change in the received setting. A lighting system including such a presence detection system and a presence detection method are also disclosed.
