Abstract: “A method is provided for determining color coordinates (XYZ) of light emitted by each emitter (R, G) of a matrix display (M), using already available information about color coordinates (XYZ) for similar light emitters with similar color characteristics other than those present in the matrix display. The method includes acquiring at least two intensity images of each emitter of the matrix with different filtering, at least one of the intensity images being acquired with filtering by at least one of said acquisition filters, and determining for each emitter of the matrix estimated color coordinates of the emitter based on the already available information and the intensity images.

Abstract: The present invention relates to an interactive system (1) for controlling lighting and/or image playback, the system comprising: at least one image acquisition device, in particular a video camera (2); a base module (3) configured to receive and analyze information from the image acquisition device (2) in order to detect the presence of at least one person (P) in the field of the image acquisition device; and at least one control module (4) configured to receive a control signal coming from the base module (3) and, as a function of said control signal, to control the intensity and/or the orientation of at least one light source (5) and/or at least one played-back visual content, in order to comply with a predefined lighting relationship.
