Coded light detector

摘要

A coded lighting system comprises a set of light sources and a remote control unit or an arrangement. The set of light sources emits coded light. In order to do so each light source is associated with a unique identifier. The remote control unit or the arrangement comprises an image sensor which captures images comprising light emitted by at least one of the light sources in the set of light sources. By analyzing the captured images the remote control unit or the arrangement is able to associate light sources affecting a particular region and/or object. The remote control unit or the arrangement is thereby able to transmit a control signal comprising updated light settings to the set of light sources.

主权项

1. A remote control unit for controlling a set of light sources, comprising
an image sensor arranged to capture at least one image and to detect coded light in said at least one image; a processing unit arranged to:
receive at least two images from the image sensor, and detect a difference between the at least two images;determine a region and/or object in an image captured by the image sensor;use said detected coded light to identify a set of light sources emitting said detected coded light that are illuminating said region and/or object, each light source having one or more light settings; andreceive an input signal relating to updated light settings of said set of light sources; and a transmitter arranged to transmit a control signal corresponding to said updated light settings to said set of light sources.
