Abstract: A system suitable for backlighting is provided. The system comprises a monitor unit configured to monitor an information signal, and to generate a first signal based at least partly on the information comprised in the information signal, a control unit configured to control properties of light radiation emitted from at least two illumination areas comprised in the system, based on the first signal and the position of each illumination area in the system, and the integration time of each illumination area depending on the position of each illumination area in the system. The system provides for a more peaceful backlighting effect while still being able to stress action happening on the main screen (e.g. motion). A method and computer-readable medium is also provided.
