Abstract: A portable colorimeter housing has an upper portion which is mounted on a lower portion in a cantilever fashion and is adapted to receive sheets larger than the device for purposes of obtaining tri-stimulus color measurements. An adjustable paper guide determines the distance that a sheet is inserted between upper and lower plates. A sheet to be measured inserted in the opening will operate a micro switch which activates a motor operative to advance the sheet between a motor-driven drive wheel in the lower plate and an idler roller in the upper plate. Transmittance or reflectance measurements are taken by means of photodetector cells including colorimetric filters. A user programmable processor performs pattern recognition and control functions. An optical housing assembly mounted on the upper plate includes a substantially cylindrical body provided with a horizontally extending channel and a mounting bar disposed in the channel is insulated from the cylindrical housing by air space except in peripheral areas of the cylindrical portion, thereby conducting heat generated by the high intensity light source to an area away from heat sensitive filters.

Abstract: A device for discriminating variations in the magnitudes of color differences. It is composed of an optoelectric conversion device consisting of a CCD facing a sample at a right angle with respect to the optical axis of the CCD. The can be moved by stepping motors along the X and Y coodinates on the plane on which the sample is mounted. The stepping motors are controlled by an 8-bit personal computer. Rods are used to move the CCD. The variations in the magnitudes of the color differences are sensed at certain X and Y positions in finite time intervals. A Xenon lamp is used as a light source to illuminate the sample. The system of discriminating variations of the magnitudes of color differences consists of a CCD image, a 16-bit personal computer, an AD converter, and a CRT. The discrimination is carried out by using subjective equivalent hue data and functional data on the personal computer. The former is given by the upper and lower limits to the subjective equivalent hue with respect to the standard stimuli at a certain wavelength in the visible range to standard eyes having a specific color sensation. The latter is obtained from the spectral response of the optoelectric conversion device, i.e., the CCD imager.

Abstract: The stack reflectance is predicted from an on-line, wavelength dependent measurement of the sheet reflectance and the on-line measurement of the sheet opacity at a wavelength interval. The stack reflectance Rst is then used to predict and/or control stack color, preferably by using the parameter K/S=(1-Rst.sup.2)/2 Rst where K is the dye absorption coefficient and S is the dye scattering coefficient.

Abstract: A light measuring device wherein a correct measured value can be obtained even if incident light varies in time or a luminance or brightness of an object for measurement is insufficient. The device comprises a branched optical fiber of a random specification having therein three mutually independent light transmission paths for introducing light from a common input end to three output ends. The input end of the optical fiber is located at a slightly defocused position of an objective lens while the output ends are individually opposed to three light receiving elements having different spectral sensitivities. Three components of light are simultaneously converted into electric signals and then into digital values by circuit means each including a double integration analog to digital converter. When a luminance is insufficient at a light receiving element, the gain of the associated analog to digital converter can be adjusted so as to assure appropriate measurement of light.

Abstract: In a colorimeter including a light source, a first quantity of light is directed toward a color sample and from the color sample toward a single photoelectric receiving and measuring device which is capable of measuring amounts of primaries or tristimulus values in quantities of light. A first carriage has mounted thereon an X primary filter, a Y primary filter and a Z primary filter, and such first carriage is reciprocable so that a selected primary filter may be positioned in front of the single photoelectric device. Adjacent the light source is mounted a second carriage which supports thereon an X primary filter mirror, a Y primary filter mirror and a Z primary filter mirror. The second carriage is reciprocable to position adjacent the light source a selected primary filter mirror corresponding to that primary filter positioned adjacent the photoelectric device. A second quantity of light from the light source is directed toward the selected primary filter mirror which reflects and changes the spectral characteristics of the second quantity of light. This second quantity of light is then directed toward the color sample and through the selected primary filter to the photoelectric device. Thus, the photoelectric device simultaneously receives two quantities of light and measures a resultant amount of the selected primary or tristimulus value therefrom.
