Abstract

It is disclosed a method for associating pixels of visual content displayed on a display unit with pixels of lighting modules, where each lighting module comprises a plurality of pixels, and the lighting modules are adapted to be comprised in a lighting system comprising a plurality of lighting modules and a control device, wherein the control device is adapted to communicate control signals to the lighting modules. Each of the lighting modules may communicate control signals with neighboring lighting modules, and to any of the pixels of the lighting module. Pixels of the visual content may be selected by means of a visual representation of pixels associated with the lighting modules displayed onto the display unit, wherein each pixel of the visual representation corresponds to a pixel of the lighting modules. Pixel values of the visual content may be associated with respective pixels of the visual representation on the basis of positions of pixels of the visual representation relatively to positions of pixels of the visual representation, and pixel values of the visual content. By communicating controls signals, for each pixel of the visual representation associated with a pixel value, corresponding to the pixel value to the pixel of the lighting module that corresponds to the pixel of the visual representation associated with a pixel value, a user may in principle view a result of the pixel association on the lighting modules in real-time. It is further disclosed a system adapted to perform the method.
