Abstract: A multispectral sensor device comprises a plurality of optoelectrical transducers (1), each of which wavelength-selectively generates from an optical signal an electrical measurement signal in its own measurement channel. A processing circuit (2, 3, 4) processes each electrical measurement signal to produce measurement signal values. A fuzzy-logic circuit (6) performs a comparison of the measured signal values with reference values and on the basis of that comparison allocates measurement signal values to a number of channels (7), that number being greater than the number of measurement channels.

Abstract: There is provided a portable, high precision color measuring device (22) for measurement of color of non-self-luminous objects. A spectral analyser (58) separates light reflected from an object (32) into spectral components and produces signals corresponding to the levels of spectral components of the reflected light. The device utilizes a dual beam (40, 44) reference system and an illumination homogenizing chamber (92) to negate the effect of instrument component variations and ensure high precision measurements at any instrument orientation. Also, the device optimizes its measurements by adjusting the gain level of each signal produced by the spectral analyzer with a programmable gain amplifier (84, 86). In addition, the device includes various features that compensate for variations in light source intensity and illumination, color temperature, displacement of the device during measurements, alteration of control button position, and adaptability to various optical geometries.

Abstract: Method and apparatus (70) for sensing the color of articles (82) and for classification thereof, wherein a first pair of wavelengths is selected on a plurality of light reflection curves (12-22) in terms of a reflected light wavelengths spectrum. An article (82) to be inspected is illuminated with light (98) comprising the first pair of wavelengths and light reflected (100) therefrom is measured to detect light reflection values corresponding to this first pair of wavelengths. A primary signal is produced, which represents either a difference between or a ratio of the detected light reflection values, this signal being indicative of the color of the inspected article (82). At least one secondary wavelength is selected on the reflected light wavelength spectrum, and the inspected article is illuminated with light comprising this secondary wavelength and light reflected therefrom is measured to produce a secondary signal which is further indicative of the color of the inspected article. A computer (78) provides a classification frame (42) comprising a first pattern consisting of first and second crossing sets of lines (44, 46) respectively defined by mathematical analysis, this classification frame defining a plurality of color classes (Cij). The computer (78) classifies the inspected article in one of the plurality of color classes defined by the frame (42), whenever the primary and secondary signals comply with a specific condition. The computer (78) rejects the inspected article (82) whenever the primary and secondary signals do not comply with this specific condition.

Abstract: Before the recognition of colour, one must determine the colour coordinates (location of the colour) of the characteristic sampling points located within the colours to be recognized and assign to them colour numbers of sample which are stored in a colour recognition memory. From the colour numbers of the samples all the colour numbers of the other colour locations of the colour domain are established and stored. The colour locations, respectively the memory locations having the same colour number constitute a colour recognition domain whithin the colour domain. For a subsequent correction of the delimitation of a colour recognition domain, at least one additional colour sample of a colour to be recognized is taken off in the desired modification zone and the necessary sample colour number is assigned to it. The colour numbers located within a local erasement zone around the colour location of the additional colour sample are erased and therefore new colour numbers for the erasement zone are calculated and stored, including all the sample colour locations and the sample colour numbers.
