Abstract: A method and a system are disclosed that make it possible to select and present colors based on a semantic search thus making the color selection process more human-compatible. A word-based search mechanism makes it easier to translate a designer's inspiration to color selection. The colors selected by using the semantic color search engine have numeric color information associated with them. This enables use of the results by design software and color software used in production processes.

Abstract: A method for the production of a digital colour catalogue, which comprises a) drawing up a requirement profile for the desired dyeing, b) selecting a group of dyes that meet the requirement profile that has been drawn up, c) determining within the colour space the colour position of the said dyes for the desired dyeing, d) segmenting the colour space of the dyes within a depth of shade plane into triangular areas according to shade, wherein the corner points of the triangular areas correspond to the colour position of the dyes in question, and the said dyes define a range of shades delimited by the triangular areas, e) dividing the triangular areas within a depth of shade plane arithmetically into a grid in such a manner that the points of intersection of the grid are distributed evenly over the triangular areas, where the points of intersection of the grid correspond to a colour position and a reflectance curve calculated on the basis of a dye recipe is associated with each of those colour positions, and f) if desired visualising the reflectance curves associated with the colour positions by means of a suitable medium, is suitable for providing a comprehensive catalogue of different shades together with the associated dye recipes.

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: An optical sensor for more accurate measurement, an optical sensing method, a program, and a recording medium. The optical sensor measures the luminance characteristic of a specific color outputted from a display illuminated with a specific illuminating light. Light separating means (60f) of the optical sensor separates the color component of the illuminating light from the color component of the specific color. A converting section (60g) for a display converts the separated color component of the specific color from LMS to XYZ by using an operand Md for the display. A converting section (60h) for illumination converts the separated color component of the illuminating light from LMS to XYZ by using an operand Mi for illumination. Thus, the conversion from RGB to LMS is carried out by independently using the operands for the display and illumination, and hence high-accuracy measurement can be made even for the superimposed colors of the output of the display and the illumination light.

Abstract: A computer based expert system and method of grading gems by their inherent properties of shape and color, including hue-tone-saturation. Each of the properties is variable over a practical range derived from a data-base; the database prepared by digital methods from real gems.The grading is conducted interactively on-screen by visual comparison to the image of a real target gem, and the result, translated into alpha-numeric code, can be communicated by phone or via the Internet to any other user of the same system and data-base. The communicated code can be reconstructed by the system into an identical gem image, enabling remote discussion and evaluation of the same target gem, including matching and pairing of gems.A practical embodiment of the grading system and method is described, including application modes specifically aimed at gems and diamonds.

Abstract: A method is provided of determining a device spectral response for an image recording device. The method comprises obtaining a filtered light response from a number of filters of a filter set, wherein each filter has a pass band with at least one boundary defined by a transition region. In the wavelength region of interest adjacent transition regions of the same sense are substantially non-overlapping. The obtained filtered light response for each filter is stored as response data. The device spectral response is determined using the stored response data and separately determined data describing the spectral response of the number of filters.
