    Abstract: A color detector includes a light source configured to generate light with a spectrum of wavelengths; a plurality of filters in optical communication with the light source, wherein each filter is configured to pass a bandwidth of wavelengths around a different peak wavelength; and a plurality of photodetectors, each configured to receive light passed through a respective filter of the plurality of filters. The bandwidth of each filter is configured to Correspond to a bandwidth of a curve from a set of standard color matching functions. A method for improving color detection accuracy in a color detector includes matching a bandwidth passed by each of a plurality of color filters with a bandwidth and peak wavelength of a Commission Internationale de l'Eclairage (CIE) color matching function; and separately detecting an amount of light passed by each the filter.

    Abstract: A passive skin detection system includes a main body which houses a collection optics system having an image splitting device, a visible light filter mechanism having a plurality of narrow band filters and an image capture system. The image capture system stores visible light data as a plurality of digital images formed from a plurality of pixels. Each of the plurality of digital images is associated with visible light passed through a respective one of the plurality of narrow band filters. An image processing system, operatively connected to the image capture system, compares relative intensities of each of the plurality of digital images to identify one or more of the plurality of pixels having an absorption bandwidth indicating a presence of skin. The processing system determines whether a person, identified by his skin, is present in any of the images captured by the detection system.

    Abstract: A method for adjusting output ratio of an optic sensor includes the following steps: measuring and obtaining a response spectrum of the optic sensor; analyzing optic response ratios of the response spectrum at different wavelengths; designing a ratio of light reception areas of the optic sensor, the design being carried out in accordance with three aspects of “the response spectrum” “a fixed proportional relationship being present between multiplication of the optic response ratio and the light reception area and an output of light current” and “a proportional relationship being present between the light reception area and the output of the light current”; and obtaining light current outputs of identical proportions (such as 1:1:1) or in a desired ratio (meaning any arbitrary ratio other than 1:1:1, such as 1:2:1, 1:2:3, or 3:4:5) in accordance with the design of the previous step.

    Abstract: A method and a system for improving the psychovisual experience of watching a display are presented. Measurements on the ambient light are performed by a sensor element, from which characteristics of the ambient light are derived. These are subsequently applied in a light-source adjustment model to determine the output of the light-source element. Moreover, a method and a system for adjusting the output of a light-source element by a feed-back loop involving the output from the light-source element and the input to a sensor element are revealed. In addition, the sensor element is also employed for adjusting the output of an electronic display by applying the results of the measurements to a preference model.

    Abstract: The invention relates to an illumination device (1) with a number of light emitters, for example LEDs (L1, L2, L3, L4) of individual emission spectra. Sensor units (D1, D2, D3, D4) can produce a vector of measurement signals (S1, S2, S3, S4) that represent the light output of a single active light emitter. Based on a linear relation obtained during a calibration procedure, a characteristic value of the light output of that light emitter (L1, L2, L3, L4) is then calculated from the measurement vector, wherein said characteristic value is based on the coefficients of a decomposition of the individual emission spectrum into basis functions.
