Controlling a lighting system

A lighting control apparatus for controlling a lighting system, the lighting system comprising at least two luminaires arranged to illuminate a physical space, the lighting control apparatus controlling the lighting system to render a version of a selected scene image in the physical space, the lighting control apparatus comprising:

• an image input configured to receive, from an imaging device at least one image of the physical space;
• an image processing module configured to use the captured at least one image to determine, for each of the at least two luminaires, at least one location in the physical space associated with said each of the at least two luminaires;
• a user interface configured to receive from a user a selection of a scene image to be rendered;
• a color selection module configured to process the selected scene image to select at least two colors in the scene image for rendering, and to determine a location of each of the selected at least two colors within the scene image;
• a color mapping module configured to compare determined scene image locations with the determined luminaire locations so as to identify, for each of the determined scene image locations, a matching one of the determined scene image locations in the physical space;
• and
• a control module configured to control the luminaire associated with that location in the physical space to emit illumination rendering a color at that scene image location, thereby causing the luminaires to render a version of the selected scene image in the physical space.
