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: A test apparatus comprising a self illuminated light source and second moveable element having spectrophotometrically neutral gray and color patches of predetermined hues and saturations. A digital software file provides identical spectrophotometrically neutral grayscale and color data which, when reproduced on a monitor or projection system, should match the grayscale and test colors provided by the apparatus. When the apparatus is placed in front of the monitor image or projected image, the neutral grays and color patches reproduced on the monitor image or projected image are compared against the image of the apparatus.

The aperture (B) lies substantially in the focal plane of the input lens (L1), and the diffuser (D) is arranged in the immediate vicinity of the aperture (B) and in the focal plane of the sensor lens (L2).
