    Abstract: Methods and apparatus enable compensation of source light wavelength fluctuations due to instability of a broadband source within an optical sensing system. Tapping off two or more portions of the light output from the source at specific wavelength bands enables power based measurements of these portions. The measurements provide compensation ability by either use as feedback to control the source or for determination of the central wavelength so that adjustments can be applied to sensor response signals received at a receiver.

    Abstract: Disclosed examples of lighting systems having at least three light sources of different colors may be controlled by validating input settings representing chromaticity and/or intensity of desired light to be generated by determining if the respective lighting system is capable of generating the desired light. This may involve comparing the chromaticity and/or intensity to a three-dimensional gamut representing chromaticity and associated intensities that the lighting system is capable of generating. The top contour of the gamut represents the maximum intensities for every chromaticity which the lighting system is capable of generating. Specifically the top contour is defined by points representing the maximum attainable intensities that each light source is capable of generating and the maximum intensity attainable by the lighting system.

    Abstract: The illumination system has a plurality of light emitters (R, G, B) and a light collimator (1) for collimating light emitted by the light emitters. Light propagation in the light-collimator is based on total internal reflection (TIR) towards a light-exit window (4) of the light-collimator. At least one light sensor (8) for optical feedback is placed outside the light-collimator and is arranged to receive light emitted by the light emitters exclusively through reflection at the light-exit window of the light-collimator. Preferably, the light sensor is placed substantially coplanar with the light emitters. Preferably, a side wall (35) of the light-collimator is provided with a protruding portion (9) for guiding the light reflected at the light-exit window of the light-collimator towards the light sensor. Preferably, the illumination system is provided with a reflector (12). Preferably, the illumination system comprises a holographic diffuser (17). Accurate sensing of the color mixing of light emitted by the illumination system is obtained.

    Abstract: One or more display color characteristics of an electronic device are managed using a light detecting sensor configured to output multiple color channels in a predefined color space. The light detecting sensor in the electronic device senses ambient light and outputs measurements in visible color channels of the predefined color space to characterize the sensed ambient light. A ratio of one or more measurements of one of the visible color channels to one or more measurements of another of the visible color channels is determined. At least one light source generating at least a portion of the sensed ambient light is classified based at least in part on the determined ratio, wherein the determined ratio indicates a color temperature component of the sensed ambient light. The one or more display color characteristics of the electronic device are adjusted based at least in part on the classifying operation.
