摘要： A method has been developed to monitor the aging of an illuminator (such as a lamp) and the interior sphere wall in a sphere-based color measurement instrument. This monitoring process or method is configurable to independently monitor the aging of the illuminator as well as the aging of the interior surface of a color measurement device using standard calibration measurements already present in the color measurement device.

摘要： In one example, an electronic signal is received from a target color measurement instrument that includes a plurality of color channels. A response of the target color measurement instrument to a light emitted by a target light emitting device is extracted from the signal. The response is calibrated to minimize a difference between the response and an output of a color matching function of a standard observer. Calibrating includes multiplying the response by a calibration matrix. The calibration matrix combines measurements of a first plurality of lights from a tunable light source and measurements of a second plurality of lights from the target light emitting device. A first subset of the measurements of the first plurality and second plurality of lights are made by the target color measurement instrument and a second subset of the measurements of the first plurality and second plurality of lights are made by a reference spectroradiometer.

摘要： A system and apparatus for the color calibration of images recorded through a microscope. An integrated color calibration target microscope slide device and specimen are recorded with an imaging device that acquires both the color values of the specimen and the color values of the color calibration target under a plurality of illuminations and trans-illuminations. A composite image is formed to provide a spectral estimation of the relevant color values of the image. The image is converted into multi-stimulus values governed by a plurality of illuminating conditions. The multi-stimulus values are used to provide image calibration data so that color values of the image, when displayed on a display devices, are faithfully reproduced.
