    Abstract: For the colour measurement of samples printed on a substrate including a brightener, a raw spectral reflection factor of the sample is measured in a first measurement by illumination of the sample with light without UV portion. In a second measurement, a fluorescence spectrum of the sample is measured by illumination of the sample with only UV light. The measured fluorescence spectrum is recalculated as a corrected fluorescence spectrum by weighting with spectrally dependent correction factors and, finally, the measured raw spectral reflection factor and the corrected fluorescence spectrum are added to form a corrected spectral reflection factor from which the values characterizing the colour of the sample are then calculated. The spectral correction factors are determined during the device manufacture for a certain set of light types and stored in the device.

    Abstract: A chromaticity testing device of a CRT phosphor screen is provided, which enables the on-line automatic testing. A supporting member is provided for supporting a face panel of a color CRT having a phosphor screen therein. A light source emits UV light toward the phosphor screen placed on the member. A movable sensor unit senses visible light emitted from a position of the phosphor screen due to the illuminated UV light and outputs chromaticity signals for the red, green and blue components of the visible light thus sensed. A judgment section receives the chromaticity signals outputted from the sensor unit to determine the chromaticity values corresponding to the chromaticity signals thus received, and compares the chromaticity values thus determined with corresponding preset values to thereby judge whether the chromaticity values are acceptable or not. A control section controls the sensor unit and the judgment section. The sensor unit is located to be contacted with the surface of the face panel on sensing to avoid the effect of external light under the control of the control section.

    Abstract: Polychromatic light is directed at the surface of a live tooth and color data of light reflected therefrom is recorded, multiplied by the stored power distribution of a first standard illuminant and converted to three tristimulus values. Such values are compared with color values of a first group of stored color dental shades, and if a match occurs within a given tolerance, an indication of the nature of the recipe is produced. A second level search may be carried out against a substantially larger group of stored dental shades in the event of a no-match condition resulting from the first search. Excellent lifelike reproduction of the patient's tooth is enhanced by checking for least metamerism by operating upon the measured data with other illumination standards and selecting the best match under all lighting conditions. Additionally, a translucency factor is calculated, and employed to reduce the opacity of the inner opaque layer of the recipe which would otherwise be indicated should the patient's tooth not have a high degree of translucency. The calculation of a fluorescence factor also enhances excellent reproduction of the live tooth, and is employed to indicate the addition of a fluorescent ingredient to the final recipe.

    Abstract: PROBLEM TO BE SOLVED: To provide a recording device which performs efficient color measurement according to a sheet.SOLUTION: A recording device controls measurement of a spectral reflection factor of a patch image recorded on a sheet in such a manner that a spectral reflection factor of a patch image is measured by using at least one of a first light source emitting visible light and a second light source emitting ultraviolet light. A spectral reflection factor of a reference patch image of a sheet color is measured by using the second light source, so as to determine whether the spectral reflection factor includes a spectral reflection factor in a wavelength band of visible light. When it is determined that the spectral reflection factor in a wavelength band of visible light is not included, control is performed so that the spectral reflection factor of the patch image is measured by using the first light source, and when it is determined that the spectral reflection factor in a wavelength band of visible light is included, control is performed so that the spectral reflection factor of the patch image is measured by using the first light source and the second light source.
