Abstract: Light (L) from a light source (3) passes through a sample cell (S) and is shone into a spectral unit (13). The spectral unit (13) comprises interference filters (31−39) transmitting optical components having different wavelengths, and photodiodes (41−49) respectively corresponding to the interference filters. A dielectric film constituting an interference filter has a property of comparatively efficiently reflecting optical components other than those having wavelengths permitting transmission. An incident light is divided into a transmission optical component and a reflection optical component at each of the interference filters. A reflection optical component is used as an incident light to a succeeding interference filter to thereby detect optical components of nine types of wavelength.

Abstract: A method and system for effecting an appearance model correction for a display unit, e.g., a CRT, using a polynomial-based algorithm is described. The correction may be effected in real time and is based on gamma values associated with the display. Strong correlations with the CIECAM02 specification are achieved according to the present disclosure. The correction functionality may be implemented using a colorimeter that includes a plurality of sensors/filter systems with non overlappng spectral responses, adequate for providing data capable of translation into standard coordinates system such as, CIE XYZ, CIE L* a* b*, or CIE Luv, as well as non-standard operable coordinate systems. The field of view of the colorimeter is chosen to closely track the response of the human eye using an optical path configured to select and limit the field of view in a manner that is insensitive to placement of the colorimeter on the source image. The optical path from the source image to the sensor is configured to select preferred light rays while rejecting undesirable light rays to maximize the signal/noise ratio. A rearward facing sensor channel is included to simultaneously measure ambient light impinging on the source image and feedback means to provide status and/or change of information.

Abstract: The invention concerns a scanner comprising an integrated photosensitive linear sensor (20) including N photosite parallel lines, with N ≥ 4, preferably, N ≥ 6, and for each photosite line an associated passband optical filter. For each scanning pitch and for each pixel of the analyzed line, it delivers N corresponding quantified partial measurement values, each representing the spectral reflectance of the document collected through the N respective filters. Spectral reconstruction means operate in accordance with an extrapolation method accompanied by learning from reference coloured samples, with a memory (42) storing a knowledge base formed from known spectral reflectance values of said reference samples, and a neuronal network (40) receiving in input N quantified partial values and delivering in output at least one reconstituted quantified value, representing the spectral reflectance of the corresponding pixel of the document.

Abstract: A color measurement system (5) includes a multi-purpose filter and optics assembly (36). The filter and optics assembly includes at least one tube array (60) for segmenting received light. The segmented light is mixed and the polarization qualities of the light are modified so to minimize the effects caused by angular adjustments. A diffuser (56) mixes the segmented light. Additionally, the color measurement system includes an ambient light attachment (24) for collecting light from the viewing area surrounding a computer display. The ambient light collected is then analyzed, and a viewing area profile is created. The viewing area profile then can be used by software to adjust the colors displayed on the computer displays.

Abstract: Die Erfindung betrifft einen Photosensor zur Farbmessung auf Basis von drei Spektralanteilen, insbesondere für die hochgenaue Farbmessung bei der Prüfung und Sicherung der Farbkonstanz von technischen Oberflächen und beliebigen Konsumgütern.
Die Aufgabe, eine neue Möglichkeit zur Farbmessung auf Basis eines Dreibereichsverfahrens mit durch vorgelagerte unterschiedlich spektralempfindliche Interferenzfilter erzeugten Farbmesswerten zu finden, die mit einfachen Mitteln eine nahezu normgerechte Echtfarben-Messung ohne aufwendige Bezugslichtkalibrierung gestattet, wird erfindungsgemäß gelöst, indem der Photosensor aus mindestens drei mit unterschiedlichen auf die X-, Y- und Z-Spektralcharakteristik des menschlichen Auges angepassten Interferenzfiltern bedeckten Teilflächen besteht, die jeweils flächengleich und kreissektorförmig gleichverteilt um ein Zentrum mit dazwischenliegenden passivierten Stegen angeordnet sind, und jede Teilfläche mit einem in seiner Transmissionscharakteristik über die Wellenlänge des spektral zu messenden Lichts der Empfindlichkeit des menschlichen Auges angepasstes Interferenzfilter versehen ist, wobei die durchgelassenen Spektralanteile der Interferenzfilter jeweils den Normspektralwertfunktionen des menschlichen Auges in Farbkoordinaten des Farbraumes angenähert sind.

Abstract: An image processing apparatus and method for measuring spatial and spectral information from an image of a printed substrate. The image processing apparatus processes the spatial and spectral information from the same acquired image using first and second processors. One of the first or second processors includes a large format sensor and the other of the first or second processors includes a small format sensor. Both the first and second processors are capable of processing both the spatial and spectral information and neither the first or second processor is necessarily dedicated to processing only the spatial or spectral information.
