摘要： A device comprising an input for receiving image data representing light captured by a camera, and an image analysis module for detecting a coded light component modulated into the light with a modulation frequency. The camera has an exposure time, and the light is captured over a sequence of exposures each lasting for an instance of the exposure time. The detection performed by the image analysis module experiences a frequency blind spot in said detection due to an effect of said exposure time. To address this issue, the device further comprises an output for controlling one or more parameters of the camera which affect the exposure time, and a controller configured to control the one or more parameters to avoid that the modulation frequency corresponds to the frequency blind spot.

摘要： A coded light component is modulated into emitted light on one of multiple channels each having a different modulation frequency. Modulation in the light causes a receiving camera to experience an apparent temporal frequency due to sequential capture of multiple frames and an apparent spatial frequency due to sequential exposure of spatial portions within each frame. Each channel can be detected by a detection module of the camera based on a respective combination of values of the apparent temporal and spatial frequency corresponding to the respective modulation frequency. The detection module has a respective response on each channel that varies as a function of the apparent temporal frequency. The channel for modulating the coded light component is selected from amongst a predetermined set having a property that the response of the detection module on each channel will have a minimum substantially at the apparent temporal frequency of each other channel.

摘要： 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.

摘要： The invention provides a communication system (500), a lighting system, a method of transmitting information and a computer program product. The communication system according to the invention is configured for transmitting data via visible light. The communication system comprises a signal generator (530) for generating a light driving signal (200) being a frequency shift key modulated signal comprising a sequence of signal parts (215, 225), each signal part being modulated at a first or second frequency in accordance with the data, the signal parts modulated at the first frequency having first pulses in first periods (T0) and the signal parts modulated at the second frequency having second pulses in second periods (T1). Energy of the visible light corresponding to a pulse in a respective period has center of gravity in time. The pulses in the periods are positioned so that the center of gravity is at the center of the period for reducing human-perceivable frequency components in the visible light driving signal.

摘要： The invention relates to a method for enabling a user to control coded light (CL) sources. The method is performed after obtaining one or more images of a scene being illuminated by at least one CL source, the image of the CL source being present within the acquired image(s). The method includes processing the acquired image(s) to determine, based on the code embedded into the light output of the CL source, that the light output of that source is present within the scene, processing the acquired image(s) to determine the location of the image of the CL source within the acquired image(s), providing a user interface illustrating the scene, and providing a control icon within the user interface, the icon indicating to a user, based on the determined location of the CL source, that the icon is adapted to control the CL source.
