A colorimetry device includes a support base having a support surface for supporting a measurement target and a carriage to which a colorimeter is detachably attached and that is configured to move in a first direction, which is a direction along the support surface, and in a second direction, which is a direction along the support surface and which intersects the first direction, the colorimeter being configured to measure color of the measurement target, wherein the carriage includes, on an inner wall of an accommodation section that accommodates the colorimeter, a contact surface that is in contact with a side surface of the colorimeter when the colorimeter is attached or detached and a friction coefficient μ1 between the contact surface and the side surface of the colorimeter is smaller than a friction coefficient μ2 between the housing of the carriage and the side surface of the colorimeter.

A water integrity control and disinfection method and system that measures key water parameters and can diagnose water integrity instability trends that result in loss of water integrity. Relevant water parameters that are predictive of water integrity such as cell null value as measured by in-line colorimetry provide early warning and prediction of problematic trends in the water integrity so that the system can pro-actively respond appropriately and prevent, mitigate or reverse the instability trend and maintain microbiological control of the water supply.

The application discloses a sky color modeling method based on the relationship between brightness and color coordinates, which combines the solar elevation angle and the azimuth angle to solve parameters by fitting and analyzing the measured sky surface unit brightness and the corresponding color coordinates calculated based on spectral information, and finally establishes a model capable of representing the sky color distribution, so that the model with color information is established to improve the application of the sky model in the field of colorimetry. The model provided by the application estimates the real-time sky spectral data variation rule, provides a theoretical reference for building lighting simulation with spectral selective glass, and the color coordinates are more scientific and accurate than the correlated color temperature.

The invention relates to a method (20) for determining the oxygen concentration (Cox) of a powder (MP) of a metallic material (Mat) having a powder bed shape (PB), said method comprising the steps of: A) Acquiring an image (Im) of at least a portion of said powder bed, said image comprising a set of pixels (P), each pixel having a color coded according to a colorimetric coding comprising three quantities (G1, G2, G3); B) Determining the oxygen concentration of the powder from values ​​of said three quantities associated with pixels of the image, using a predefined calibration function (CFMat), a function of said material, and relating said oxygen concentration to said three quantities.

An image forming apparatus having a plurality of imaging units prints, in a case that a print job received from an information processing apparatus is a print job for printing a chart for adjustment, the chart based on the print job, and decides, based on the chart, which of the plurality of imaging units is to be used to perform colorimetry of a printed product on which the chart has been printed. The image forming apparatus changes a conveyance path of the printed product to use the decided imaging unit for the colorimetry of the printed product, and notifies the information processing apparatus of a result of the colorimetry by the decided imaging unit.

This description refers to a graphical user interface (GUI) for a colorimetry software product, a computer-implemented method for generating the GUI, and a system for performing the method.
