Abstract: A colorimeter or color measuring device measures color of a sample or an object, and displays measurement value or values according to user defined index or indices, calculated by a user-defined formula. Data of the user-defined formula is read in from outside of the colorimeter and converted into a coded form which can be executed by a controller of the calorimeter. The data of the user-defined formula or the coded data is stored in the colorimeter. Accordingly, the colorimeter has good portability and convenience despite its capability of expressing the colors of various samples or objects by user-defined original index or indices.

Abstract: A method for obtaining an approximate standard colour definition for a sample colour (2) without the need for standard conditions of illumination or observation. The method comprises using colour sensing equipment such as a digital camera (6) to sense under non-standard conditions both the sample colour and a plurality of reference colours (5) each being provided on a template (1) and each having a known standard colour definition. The sensing under non-standard conditions produces a non-standard colour definition both for the sample colour and for each of the reference colours. The non-standard colour definitions of reference colours near in colour space to the sample colour are compared with the known standard colour definitions for the reference colours to obtain correction factors which are then applied to the non-standard colour definition of the sample colour to convert it to colour definition which, though it is only an approximation of the standard colour definition, is nevertheless sufficiently close to the true standard colour definition to be useful in colour matching.

Abstract: An instrument and related process for measuring color, shade, gloss, shape and/or translucence of a tooth. First, the instrument uses searchlight illumination to illuminate a tooth with constant irradiance. Second, the instrument uses calorimetric imaging to collect time-separated frames of different wavelengths of light reflected from a tooth and to combine those frames into a color image. Third, the instrument includes a sanitary shield to establish a reference color and a predetermined distance to a target tooth. Fourth, the instrument provides line-of-sight viewing so an operator may simultaneously view a display of the image on the instrument and the object being measured. Fifth, the instrument is impervious to pollutants because it incorporates a sealed measurement window. Sixth, optical measurements of a tooth taken by a dentist are compared to optical measurements of a prosthetic restoration for that tooth to confirm satisfactory matching of optical characteristics of the tooth and restoration.

Abstract: In luminance priority multilayer color film, one of the layers substantially matches the luminance sensitivity of the human eye. This luminance layer distinguishes from prior art color films that have a blue, a green, and a red sensitive layer. This luminance layer has the priority front position to sense light before being diffused and attenuated by other layers, giving the luminance record enhanced speed and clarity compared to prior art blue-priority color film. In another embodiment, a layered CCD sensor has a top silicon layer that is sensitive to all colors, followed by a yellow filter, a second silicon layer responsive to green and red light only because of the yellow filter, a cyan filter, and a bottom silicon layer receiving only green light. An image from a luminance-priority color sensor inputs to a color space conversion to recover full color. In the preferred embodiment, a luminance layer on top maps to a luminance “Y” value, and underlying color sensitive layers are used in conjunction with the luminance to derive the “U” and “V” chrominance vectors of YUV color space.

Abstract: A graphical image scanner scans pixelated regions of a color image to measure light intensities in a plurality of hyperspectral bandpasses for each pixel. The scanner transforms the hyperspectral bandpass intensities into device-independent color representations for each pixel, using scientific color representations, for example, as defined in CIE-31 and CIE-76 colorimetry standards as devised by the Commission Internatonale de l'Eclairage (CIE).

Abstract: An imaging system is disclosed comprising an illuminator which produces illumination of any desired pure wavelength or of any selected mixture of pure wavelengths simultaneously, which illuminates a sample without spatio-spectral artifacts using illumination optics designed for that purpose; imaging optics, which form an image of the sample at a detector or viewing port; and a detector. This enables imaging the complete spectral image cube for a sample by taking sequential images while illuminating with a series of pure wavelengths, with greater ease and economy than by means of tunable filters, interferometers and the like. It further enables imaging while the sample is illuminated with a precisely controlled mixture of illuminant wavelengths, so that the image presented to the detector is a linear superposition of the sample properties at many wavelengths. This enables taking images of a sample that directly measure the weighted spectral properties such as projection pursuit vectors, principal components, and the like. Data acquisition is enormously simplified, and speed is increased by one to two orders of magnitude over existing techniques. This is of great benefit in pathology, immunohistochemistry, Pap smear analysis, endoscopy, counterfeit detection, quality control, and other areas where one wishes to measure a spectral index of a living or inert sample.
