Abstract: A system including a processor and a memory configured to store code executed by the processor is provided. In one or more implementations, the processor is configured by the code to calibrate measurements made by color measurement devices. In one particular implementation, the processor receives a measurement dataset of one or more color values, for a sample obtained by a color measurement device. The processor is configured to convert the measurement dataset to a standard space measurement dataset using a standard space measurement model and calculate a color dataset based on the standard space measurement dataset using a color conversion model. The processor is further configured to output the calculated color dataset to at least one of a display, database or local memory store.

Abstract: A colorimetric apparatus includes: an opening portion that is disposed at a bottom of an apparatus main body and that introduces light arriving from a measurement target to inside the apparatus main body; an incident light processing unit that processes light incident through the opening portion; a rotor that is provided at the bottom of the apparatus main body and is in contact with the measurement target, the rotor having an elliptical shape and being driven to rotate about a rotary shaft when the apparatus main body moves in a predetermined direction; a detector that detects displacement of the rotary shaft in a direction in which the rotary shaft advances and retreats with respect to the measurement target as the rotor rotates; and a control unit that receives a signal from the incident light processing unit and the detector.

Abstract: An image processing apparatus includes circuitry that acquires a colorimetric value for each of a plurality of patches on a first chart printed out by an image forming apparatus and read by a colorimeter. Each of the patches has a monochromatic color. The circuitry further acquires a maximum tone value previously set in accordance with a sheet, and converts each of the colorimetric value, the maximum tone value, and a color system value of a first target into a particular color value. The first target represents an ideal characteristic of the color system value corresponding to a tone value. The circuitry further determines, as a second target, a characteristic passing through a point determined by a color value corresponding to the maximum tone value. The characteristic is generated based on the color system value of the first target converted into the particular color value.

Abstract: A colorimetry device includes: a colorimetry unit including an irradiation unit including a substrate provided with a LED, and a light-receiving unit configured to receive reflected light that is light irradiated from the LED and reflected by the color chart image, the colorimetry unit being configured to perform colorimetry of the color chart image; a movement unit configured to cause the colorimetry unit to reciprocate along an intersecting direction; a calibration member provided in the intersecting direction; a temperature sensor configured to detect a temperature of the LED or a temperature of the substrate; and a colorimetry device control unit configured to move the colorimetry unit by the movement unit to a calibration member and calibrate the colorimetry unit when determining that the colorimetry unit is to be calibrated for the colorimetry of the color chart image based on the temperature detected by the temperature sensor.

Abstract: Certain examples relate to emulating a spectral measurement device in a color measurement apparatus. In these examples, a primary spectral measurement device measures a first spectral characteristic of a rendered color output. A predictive model, parametrized by parameter values, is applied to the measurement from the primary spectral measurement device to determine a predicted measurement of a second spectral characteristic of the rendered color output which would be measured by an ancillary spectral measurement device. Parameter values are generated by training the predictive model with data from the primary spectral measurement device and the ancillary spectral measurement device.

Abstract: A transmission type color calibration chart includes a transparent substrate and a color bar group formed on the transparent substrate, wherein the color bar group is constituted by color bars of a plurality of colors containing at least a first color and a second color arranged in a pattern in no particular order, coordinate points of the first color are within a region encompassed by the four points (0.351, 0.649), (0.547, 0.453), (0.380, 0.506) and (0.433, 0.464) on an xy chromaticity diagram, coordinate points of the second color are within a region encompassed by the four points (0.125, 0.489), (0.112, 0.229), (0.270, 0.407) and (0.224, 0.242) on an xy chromaticity diagram, and the transmission spectrum of the first color's color bar and the transmission spectrum of the second color's color bar have peak tops that are respectively separated.
