A colorimeter capable of calibrating color monitors, whether having cathode ray tube or liquid crystal (LCD) displays, is provided by a photometric array of photodetector and optical filter pairs. The filters include long-pass, edge filters which cover overlapping regions at the upper end of the visible spectrum and a filter which covers the entire visible spectrum. The outputs of the photodetectors are digitally synthesized to provide a response which mimics the response established by the Commission Internationale de 1âEclairage (CIE) xyz (bar) functions almost perfectly. The response which is mimicked may be represented by the CIE color matching functions. The pairs and the associated components are mounted on a printed circuit board captured in a clamshell housing and having an array of apertures which define angularly constrained fields of view of a surface from which the light, to be colormetrically analyzed, emanates. The printed circuit board includes a field programmable gate array programmed to read data from the plurality of filter/detector pairs in parallel. The colorimeter is capable generally of measuring the color characteristics, especially the color temperatures of radiation radiating and reflecting bodies (sources), including so-called black bodies.

A symmetric monitor calibrator for mounting on a cathode ray tube or monitor with a surface. The calibrator has a case that holds electronic and optic components. Suction cups hold the calibrator to the surface, in which the suction cups are attached to the end of supporting elements that surround the case. At least three supporting elements with a common connecting point to form one support structure are connected to the top of the case. The supporting elements extend out creating a greater diameter than the case. The supporting elements and therefore suction cups uniformly surround the center point of the case to prevent rotation caused by the effects of gravity.

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.

A tristimulus colorimeter for measuring reflective or transmissive materials is provided. The colorimeter measures a sample under a calibrated light source, receives inputs to detectors, and determines CIE tristimulus values of the same sample as they would occur under a reference light source. The colorimeter includes a calibrated light source and a single silicon chip that includes three or more detectors. Each detector is permanently coated by a different mix of dyes or other colorants that form a wavelength-selective filter. A single silicon chip embodies all the detectors and electronics, with each detector coated over by deposited filter layers.
