Fast Color Gamut Measurement System (FCGM)

    This system is based on a calibrated camera for the gamut measurements and adjustments of displays. With certain designed patterns outputted to the display, the XYZ and other colorimetric parameters were measured corresponding to the inputs of respective ROIs. The colorimetric features of displays can be fast and accurately determined for the adjustments. 

Functions

˙Basic measurement with RGBW scales and

    representative colors

˙Fast measurement on XYZ(Yu'v’, Lab) versus YSH

    (RGB)

˙Fast alignment

˙Adjustments of CCT, lightness, saturation, tone

    curves and

 simulation

˙Averages of xy, u'v‘, or Lab in ROIs

˙Calibration of Camera

Application

˙Basic measurements of displays

˙Gamut measurement of displays

˙Colorimetric adjustment and verifications of

    displays

˙Generation of XYZ-tiff files and ICC files
