Abstract: In a measuring probe (40) according to the present invention, measuring light is split into a two or more through a split optical system (12), and, when each split light is received by a light-receiving sensor (13B, 13B, 15B) through an interference filter (13A, 14A, 15A) serving as a color filter, the split light is introduced into the interference filter (13A, 14A, 15A) through a collecting lens group (123C, 14C, 15C) formed as a substantially bilateral telecentric system. The interference filter (13A, 14A, 15A) is formed to obtain a transmittance characteristic corresponding to a measurement parameter, depending on a condition of an intensity distribution with respect to incidents angles of light incident on the interference filter (13A, 14A, 15A). Thus, the measuring probe (40) according to the present invention can reduce an influence of a deviation in the transmittance characteristic due to incident angles, even using the interference filter (13A, 14A, 15A).

Abstract: The present invention is directed to a method of utilizing a digital micromirror device (DMD) to spectrally matching a standard or device-independent color. DMD can be fitted on an integrated chip and can provide more than one thousand (1,000) color primary channels for low metameric color matching producing a spectrally matched batch color. This represents a two orders of magnitude improvement in color matching.

Abstract: Disclosed examples of optical systems having a plurality of light sources with each source having a different spectral outputs may be calibrated by measuring a spectral characteristic of the combined light with two measurements, e.g., one from a colorimeter and one from a sensor included in the system. Accordingly, one can determine a transform function in response to the two measures that models a feedback response of the optical system for each of a plurality of the inputs that would cause the optical system to generate radiant energy within a predetermined range of a spectrum. In order to calibrate the optical system, the transform function is programmed in the optical system to enable the optical system to transform an input to the optical system to a plurality of unique control signals each for controlling a respective light source of the plurality of light sources.

Abstract: 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.
