Examples of the present disclosure relate to a method for providing a status of a radiation emitter of a printing device, the method comprising image sensing at least part of a print agent after deposition onto a print substrate and after heating by the radiation emitter: obtaining, based on the image sensing, an irradiance applied on the heated print agent and providing a status of the radiation emitter in response to determining a deviation of the irradiance with respect to an expected irradiance.

Systems and methods here may be used for automated capturing and analyzing spectrometer data of multiple sample gemstones on a stage, including mapping digital camera image data of samples, applying a Raman Probe to a first sample gemstone under evaluation on the stage, receiving spectrometer data of the sample gemstone from the probe, automatically moving the stage to a second sample, using the image data, and analyzing the other samples.

A camera system with a multispectral sensor that can be used in combination with a flash to determine a spectrum of the ambient illumination without needing a separate measurement. This may then be used to colour-correct an image captured with or without flash.

The present invention discloses an online color difference detection system and detection method, and belongs to the color difference detection field, the system including: an online non-contact colorimeter and a bracket, the online non-contact colorimeter being located on the bracket, and the online non-contact colorimeter emitting a light source directed towards a sample under detection to perform color difference detection on the sample under detection, wherein an angle between reflected light received by a reflected light meter of the online non-contact colorimeter and a vertical line of the sample under detection has an error within plus or minus 1 degree from an angle between reflected light received by a reflected light meter of an offline benchtop colorimeter and the vertical line of the sample under detection.

The invention is a system for color analysis, which comprises a hand-held device and a working platform. The hand-held device is provided with a camera and installed with analysis software. The work platform is placed with an object to be tested, a standard color carrier is installed at both front and rear sides or at both left and right sides of the object to be tested, a positioning frame extends upward around the working platform, the positioning frame and the working platform are mutually formed an inclination angle, and the positioning frame is used to fix the hand-held device. In this way, the camera can shoot the working platform in an inclined direction, and then the analysis software is used to compare a color difference between the object to be tested and the standard color carrier to obtain analysis result of the object to be tested.

Color calibration for digital pathology is provided. A standard glass slide is prepared with a specimen having zero or more stains. The specimen is scanned a first time using a hyperspectral imaging system to produce a first digital image having XYZ color values. The specimen is scanned a second time using a digital pathology imaging system to produce a second digital image having RGB color values. The first and second digital images are then registered against each other to align the digital image data. Individual pixels of the first and second images may be combined in the registration process so that the first and second digital images have substantially similar pixel sizes. A lookup table is generated to associate XYZ color values to RGB color values. Once the lookup table has been generated, it can be used to present RGB color on a display using the corresponding XYZ color.
