Abstract
Systems, methodologies, media, and other embodiments associated with color measuring are described. One exemplary system embodiment includes a spectrophotometer, one or more light sources for illuminating an interior of the spectrophotometer, and a digital camera configured at a port of the spectrophotometer and being configured to measure light components from a sample. In the present invention, segmentation logic is provided for the spectrophotometer that is configured to employ computational image segmentation to characterize specular reflection from a sample and to characterize a selected patch or portion from the test sample, such as a selected color in a multicolor pattern. In accordance with the present invention, the spectrophotometer and the included digital camera may be color-characterized in situ.
