Abstract: The present invention relates to a method for minimizing the effects of metamerism between a set of color standards (e.g., nitrocellulose lacquers) and inkjet printed color merchandise (e.g., paint chips) under a plurality of illuminants, including a balanced illuminant that emulates lighting conditions between cool (6500 K) and warm (2856 K) color temperatures. For each color standard, one selects an ink combination that best produces color merchandise having a minimal degree of metamerism. Innovatively, a combination of instrumental and visual tests is used to evaluate color difference for a set of color standards-color merchandise pairs under a plurality of illuminants. If a color standard-color merchandise pair fails either test then the ink combination may be adjusted.

Abstract: A method of determining lighting contributions of elements of a lighting component includes obtaining optical data representative of light output of the lighting component. Relative intensity data may be calculated from the optical data, and may indicate intensity differences in the light output of the lighting component as compared to that of a reference component. An optical property of an element of the lighting component is determined based on a comparison of the optical data with that of the reference component, where the reference component includes at least one reference element. Related systems and apparatus are also discussed.

Abstract: Embodiments of the present invention are directed to determining the spectral vector of electromagnetic radiation reflected from, transmitted through, or emitted from a sample using a set of n intensity measurements. In general, the spectral vector has a dimension k that is greater than the number of measured intensities n. However, in many cases, the physical and chemical constraints of a system, when properly identified and modeled, effectively reduce the number of unknowns, generally the k components of the spectral vector, to an extent that allows for the spectral vector to be characterized from a relatively small number n of measured intensities.

Abstract: A method of color assessment of a sample (10) with respect to a reference illuminant, includes illuminating the sample (10) with a light source (12) that comprises a fluorescent lamp (18) and a plurality of light-emitting diodes (24). The spectrum of the LEDs (24) supplements the spectrum of the fluorescent lamp (18) to reduce deviations between the combined spectrum of the light source (12) and a target spectrum. The target spectrum may be that of the reference illuminant or it may be adjusted to make allowance for known properties of a color assessment cabinet (2) or an observing instrument (16). The LEDs (24) may be arranged so that their light passes through the bulb of the fluorescent lamp (18), which thereby acts as a diffuser. Alternatively, the LEDs (24) and the fluorescent lamp (18) may be located in a housing (31) from which their light can only reach the sample (10) after being mixed by reflection from multiple facets (34).

Abstract: The invention provides methods, systems and apparatus for assigning color names to individual image pixels, and generating verbal description of color composition in images, suitable for a wide variety of information processing applications. For an isolated image pixel (individual color sample or color value) an illustrative embodiment of this invention uses a predetermined vocabulary of color names, and then generates a distance measure describing the best color match and corresponding color name for the given pixel. For the input image, an illustrative embodiment of this invention computes the simplified representation of the scene, consistent with human perception, and uses the predetermined vocabulary, syntax rules and metric to assign color names to all perceptually significant objects and regions and obtain the verbal description of the overall color composition. The invention is also applicable to other types of information signals, such as sequences of video frames, web pages, etc.

Abstract: Sporting items such as soccer balls include a casing region and a graphic region that are defined by enhanced-visibility colors (EVCs) that are substantially complementary. Such EVCs can be selected to avoid colors associated with color confusion in color deficient individuals. In addition, such colors can be selected based on total reflectances to obtain a predetermined luminance contrast. EVCs can be selected based on separations of color coordinate locations using CIE chromaticity coordinates or CIE L-a-b coordinates or otherwise selected. Color selection can include consideration of anticipated viewing backgrounds in a general setting, or colors can be customized for a particular location and particular illumination conditions.

Abstract: A color sensor for generating color information defining colors of an image includes an input section, a color processing section, a color comparison section, a color boundary processing section and a memory processing section. The input section includes an array of transducer pairs, each pair defining one of a plurality of pixels. Each transducer pair generates two peak outputs, one for the selected color of each transducer of the pair. A plurality of pixel processors in the color processing section each receives the outputs from one of the transducer pairs. The color processing section generates a color feature vector representative of the brightness of the light incident on the pixels and a color value corresponding to the ratio of outputs from the transducers comprising the transducer pair associated with the pixels. The color boundary processing section generates a plurality of color boundary feature vectors, each representing the difference between the color value for a pixel and its neighboring pixels. The color comparator processor measures and compares the reflective color of two objects and the memory processor section provides a process to recognize a color, a boundary of color and/or a comparison of colors.
