Abstract: PROBLEM TO BE SOLVED: To provide a chromaticity instrumentation system for a visible region and an invisible region which utilizes the color values of invisible colors and color display of false-color images, and quantitatively and sufficiently evaluates desired information which is wanted to acquire from a subject sample. SOLUTION: The system 1 has a spectral optical portion 2a which separates light emitted from the subject 10 into its spectral components, a photoelectric conversion portion 2b which performs photoelectric conversion of each separated spectral component and generates an electric signal, an image processing portion 4 which forms a false-color image and calculates numerical values on a colorimetric system for performing color display of the image, and image output portions 5, 6 which output the image and/or the numerical values. The image processing portion multiplies each electric signal by a sensitivity function and generates an image signal, calculates the numerical values by using the signal, multiplies the signal by a matrix M and forms a false-color image. The sensitivity function is determined on the basis of the correlation between the differences in physical or chemical condition among subjects, and differences in waveform produced among spectra of two or more subjects, and M is so determined that a color reproduction error becomes minimum.

Abstract: PURPOSE:To achieve a quick and easy evaluation of an artificial light source for D65 light, by receiving light transmitted through five pairs of transmitting object having the same chromaticity under a reference light d65 through three filters with a specified spectrochemical transmission characteristic. CONSTITUTION:Light radiated from a lamp 1 is transmitted through a transmitting object 3 comprising five pairs of matters becoming insochroic under a reference light D65 and a matter with the transmissivity almost uniform in the visible wavelength range and made incident into a photo detector 4. The photo detector 4 comprises three filters having respectively spectochemical transmission characteristics of isochroic functions -x10(lambda), -y%d10(lambda) and -z10(lambda) established in 1964 by Commission Internationale de Enluminure. Then, light passing through the photo detector 4 converted to an electrical signal with a photoelectric converter 5 corresponding to three stimulus values Xo, Yo and Z0 of the lamp 1 itself and five pairs of three stimulus values Xi, Yi and Zi (i=1-10) of the transmitting objects 3 to be stored into a memory circuit 6. The output of the circuit 6 is converted to the chromaticity with an arithmetic unit 7 and compared with the value of the chromaticity set for a comparator 9 to show 10 whether the chromaticity fo the lamp 1 is within an allowable range of the chromaticity fo the reference light D65 or not.

Abstract: An optical type granule sorting machine is provided which allows a sensitivity setting to be easily performed by effectively utilizing RGB three-dimensional color space information similar to information obtained via human eyes and which enables signal processing to be substantially simplified. Determination means includes a three-dimensional color distribution data creation section that creates data on wavelength components of R light, G light, and B light from the granules, on a three-dimensional color space, a Mahalanobis distance interface creation section that sets an interface calculated based on a Mahalanobis distance to partition the data into a conforming-granule cluster area and a nonconforming granule cluster area, a Euclidean distance interface creation section that determines a position of center of gravity of the conforming granule cluster area and a position of center of gravity of the nonconforming granule cluster area to set an interface calculated based on a Euclidean distance at which the positions of center of gravity lie at a longest distance from each other, and a threshold determination section that determines a line of intersection between the interface calculated based on the Mahalanobis distance and the interface calculated based on the Euclidean distance, to determine the line of intersection to be a determination threshold that allows determination of whether or not the granules are to be treated as a separation target.

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.
