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.

Abstract: A tristimulus colorimeter for measuring reflective or transmissive materials is provided. The colorimeter measures a sample under a calibrated light source, receives inputs to detectors, and determines CIE tristimulus values of the same sample as they would occur under a reference light source. The colorimeter includes a calibrated light source and a single silicon chip that includes three or more detectors. Each detector is permanently coated by a different mix of dyes or other colorants that form a wavelength-selective filter. A single silicon chip embodies all the detectors and electronics, with each detector coated over by deposited filter layers.

Abstract: The present invention is an apparatus for measuring the color of a light signal. The apparatus includes a plurality of color sensing elements, an optical system for illuminating each of the color sensing elements with light from the light source, and a controller for determining the intensity and wavelength of the light signal from the signals generated by said color sensing elements. Each color sensing element generates an electrical signal that depends on the wavelength and intensity of light incident on the color sensing element. Each of the color sensing elements is characterized by a gain function that relates the electrical signal generated thereby to the wavelength and intensity of light incident thereon. Each of the gain functions is different from the others of the gain functions.

Abstract: Methods and systems for measuring with a Color Measurement System of predetermined specification and evaluating the color of skin, teeth, hair and material substances with a Color Index. The principles of this invention also relate to techniques for using such a Color Measurement System with the Color Index in medical applications such as the detection of chromogenic disease including bilirubin infant jaundice, cosmetics applications and in the evaluation of the color of hair or teeth, and other applications. The Color Index is measured and calculated from the reflectance spectrum of any skin (or teeth, hair or material substance) by a two step process. The first step is the weighting of the visible spectra with a unique set of weighting factors which calculate a sample's reflectance spectrum's contribution to the appearance of four color components independent of the illuminating condition. The second step places the sample's reflectance spectrum's contribution to the appearance of the four color components in opponency to each other and calculates the Color Index providing attributes representative of correlates of lightness-darkness (L, also referred to as lightness), redness-greenness (M) and yellowness-blueness (N).

Abstract: A method and apparatus to enable countertyping a tint by formulating a theoretical mixture of base tints having known colorimetric parameters. The apparatus employs a filter colorimeter, normally used only to compare differences in tint samples, and iteratively to define additions to enable matching tints by gauging the result of adding base tints. However, the colorimeter according to the invention is defined in its response to known standard tints, and the iterative process is then conducted in the colorimetric domain specific to the particular colorimeter. The response curves of the colorimeter are maintained in data files used to modify calculations made respecting the effects of adding tints, the characteristics of the tints to be added also being stored in the data files. The apparatus can operate an automixer.
