A method for calibrating an ambience lighting system for providing an ambient light effect for a cinema display screen is proposed. The method is based on implementing the ambience lighting system in the form of one or more of coded light (CL) sources. The method then includes processing one or more images of a scene being illuminated by the ambience lighting system to determine, based on the CL embedded into the light output of the individual CL sources, color and/or an intensity of the light generated by the individual CL source. The set of control data for controlling the CL sources to provide the desired ambient light effect is then based not only on the color and/or intensity of image content to be displayed on the cinema display screen, but also on the determined color and/or intensity of the light output of the individual CL sources.
