摘要： In a measuring probe 40, a measuring beam is diffused by a first diffusion plate 19, and when received by a plurality of light-receiving sensors 13B, 14B, 15B via a plurality of interference filters 13A, 14A, 15B, the measuring beam is made incident on the interference filters 13A, 14A, 15B via second diffusion plates 13C, 14C, 15C. Those interference filters 13A, 14A, 15B are formed such that transmittance characteristics corresponding to a measurement parameter are obtained correspondingly to intensity distribution conditions for an angle of incidence of light incident on the interference filters 13A, 14A, 15B. Therefore, the measuring probe 40 can reduce the effect of displacement of the transmission characteristic caused by the angle of incidence, while using the interference filters 13A, 14A, 15B.
摘要翻译：在测量探头40中，测量光束被第一扩散板19扩散，并且当多个受光传感器13B，14B，15B经由多个干涉滤光器13A，14A，15B接收时，测量光束为通过第二扩散板13C，14C，15C入射到干涉滤光器13A，14A，15B上。这些干涉滤光片13A，14A，15B形成为与入射到干涉滤光片13A，14A，15B上的光的入射角的强度分布条件对应地获得与测定参数对应的透射率特性。因此，在使用干涉滤光片13A，14A，15B的同时，测量探头40可以减小由入射角引起的透射特性的位移的影响。

摘要： The invention relates to a method and a device for screen calibration for the true-to-original reproduction of surface colors, the spectral reflection distribution of which is known, wherein by setting parameters the screen can be influenced using software and an electronic controller in each partial region of the screen. The invention is characterized in that an observer adapts the reproduced color impression of the screen to the color impression of an original in each partial region of the screen, wherein the original is compared to the screen colors immediately thereafter on the screen surface and the screen parameters are varied until the color impressions of the original and of the screen appear identical to the observer on the respectively viewed partial screen, viewed from a predefined observer angle, and the settings performed are stored in a screen profile.

摘要： An apparatus, methods, and systems for multi-color projection or display for video or lighting applications. One aspect of the present invention comprises an algorithm for utilizing at least four primary light sources to represent a projected pixel color. The algorithm and associated system can be applied to both a natively monochromatic light source or traditional light sources filtered for their colored components. The algorithm can be used for either color sequential or parallel modes of operation. The algorithm takes input pixel data represented in a universal color coordinate system, performs a color transform, and disperses the results among parallel display devices or sequentially to a single device such that each pixel is presented by the combination of four or more primaries.

摘要： Color calibration of color image rendering devices, such as large color displays, which operate by either projection or emission of images, utilize internal color measurement instrument or external color measurement modules locatable on a wall or speaker. A dual use camera is provided for a portable or laptop computer, or a cellular phone, handset, personal digital assistant or other handheld device with a digital camera, in which one of the camera or a display is movable with respect to the other to enable the camera in a first mode to capture images of the display for enabling calibration of the display, and in a second mode for capturing image other than of the display. The displays may represent rendering devices for enabling virtual proofing in a network, or may be part of stand-alone systems and apparatuses for color calibration. Improved calibration is also provided for sensing and correcting for non-uniformities of rendering devices, such as color displays, printer, presses, or other color image rendering device.

摘要： The invention relates to a method for two-dimensional, spatially resolved measurement of tristimulus values of light emitted from a plurality of positions on a sample. It is an object of the invention to provide an improved method and system for spatially resolved chromaticity and luminance measurement in a standardized color space for display testing. The method of the invention comprises the steps of: - directing a first portion of the light to an RGB camera which produces a two-dimensional map of RGB color values; - transforming the RGB color values into first tristimulus values to produce a map of tristimulus values; - directing a second portion of the light to a colorimeter which produces second tristimulus values; - deriving a tristimulus correction by comparing the second tristimulus values with at least a subset of the first tristimulus values; and - applying the tristimulus correction to the first tristimulus values to produce a corrected map of tristimulus values. Moreover, the invention relates to an imaging colorimeter system capable of two-dimensional, spatially resolved measurement of tristimulus values of light emitted from a plurality of positions on a sample.
