Abstract: A calculation unit (112) acquires a dedicated base vector based on a known spectral characteristic of a subject as an identification target having the known spectral characteristic from a base vector ROM (114), and acquires a spectral characteristic of an imaging system including a spectral characteristic concerning a color imaging system used for image acquisition of subjects including the subject as the identification target and a spectral characteristic concerning illumination light used when image acquisition of the subjects by the color imaging system from a system spectral characteristic ROM (115). Then, it calculates a weighting factor concerning the dedicated base vector based on an image signal obtained by image acquisition of the subject by the color imaging system, the dedicated base vector, and the spectral characteristic of the imaging system. A normalization unit (116) calculates an identification result of the subject which is the identification target having the known spectral characteristic based on the weighting factor concerning the dedicated base vector, and outputs it as an output signal by an output unit (117).

Abstract: The invention relates to a method for regulating the ink in a printing press, in which a stock (09) is continuously printed in an on-going printing process of the printing press, at least one ink is applied to the stock (09) in several inking zones (22; 22A; 22B; 22C; 22D), a measured value indicating an ink density is determined for the at least one ink applied to the stock (09) in said printing process within the printing press, and a relation is formed between the measured ink density value for a specific ink in a selected inking zone (22; 22B) and a measured ink density value determined for the same ink in at least one other inking zone (22; 22A; 22C). The relation between the measured ink density values in different inking zones (22; 22A; 22B; 22C; 22 D) is formed only if the majority of the inking zones (22; 22A; 22B; 22C; 22D) of a specific inking unit (07) of the printing press supply one respective measured ink density value for an ink supplied by said inking unit (07), said measured ink density value reaching at least a predefined fraction of a preset desired value in the respective inking zone (22; 22A; 22B; 22C; 22D).

Abstract: Light sensors (1) are used in lighting applications, especially in combination with LEDs, to control and/or adapt the color point of light sources. Costs and/or performance of the light sensor (1) are essential in order to guarantee cost- effective light sources with reproducible color points. This aim is achieved by a light sensor (1) comprising a light diffuser (10), an optical non-transparent housing (11) having at least one window (12), at least one interference filter (13) and at least two photo sensors (14). The light diffuser (10) is arranged in such a way that light from outside the optical non-transparent housing (11) has to pass the light diffuser (10) so as to enter the interior of the optical non-transparent housing (11) via the window (12). The interference filter (13) and the at least two photo sensors (14) are arranged in the interior of the optical non-transparent housing (11), which interference filter (13) is arranged between the window (12) and the at least two photo sensors (14).

Abstract: Device and method for inspecting a polychromatic region, such as a polychromatic pattern, on a moving workpiece. The method includes device includes a solid-state light source, preferably a light emitting diode, adapted to emit light in a range of wavelengths for illuminating the polychromatic region. Photodetectors are positioned relative to the workpiece to intercept light from the light source reflected by the polychromatic region- Each of the photodetectors is adapted to detect reflected light within a corresponding one of a plurality of bands defined within the range of wavelengths. The method includes detecting intensities of the light reflected from the polychromatic region within different wavelength bands in the range of wavelengths and evaluating a ratio of the intensities for comparison with a standard ratio to ascertain a variation in the evaluated ratio.
