Abstract: A color measurement system is provided that includes an integrating sphere having at least one specular component included (SCI) sensor configured to output a signal in response to light incident thereupon and at least one specular component excluded (SCE) sensor configured to output a signal in response to light incident thereupon, a sample port, a SCE port, a light source configured to direct a beam of light into the sphere and provide illumination at the sample port and a specular component excluded port. The system also includes a processor having a memory and configured by code to activate the light source so as to cause a beam of light to be directed into the sphere and provide illumination to the sample port. The processor is also configured to receive a signal output by the SCI sensor and a signal output by the SCE sensor. Furthermore, the processor is configured to obtain at least one measurement coefficient value and generate a corrected SCE measurement value using at least the SCI sensor value, the SCE sensor value and the obtained measurement coefficient. The processor is configured to output at least the corrected SCE measurement value and the SCI measurement value.

Abstract: A method and a system are provided to measure transmittance or reflectance of a color specimen by using a transformation matrix obtained from the measurement values of a series of known transmittance or reflectance calibration color standards and multiple flashes from different illumination sources. A color spectrum can be determined with reduced error by calculating the reflectance spectra of an object using measurement matrices obtained under at least two illuminants and the transformation matrix.

Abstract: A system and method for correcting the color of microscope images is described wherein a microscope, equipped with a variable light source and at least one microscope setting selector operates in conjunction with an image recording device having at least one image setting selector with a plurality of settings, and is configured to record at least one white balanced sample image of a sample. The system and method also includes the use of at least one white balanced calibration image of an integral transmissive color filter array of known transmission values in combination with an image processor executing code in order to color calibrate the sample images based on the calibration image.

Abstract: The present invention concerns a system and method for calibration and adjustment of the pixel color values represented within a digital image of a sample by a transmission microscope. Furthermore the present invention is directed to providing sufficient color information in order to generate a color mapping matrix that allows for the creation of a synthetic image to depict the sample under a desired illumination. The system and method provides a solution that generates a destination-device independent image that is configurable to any calibrated display device.
