Patent

CA 2224891

The invention features a colour measuring device comprising: an acquisition system (2, 6) comprising a video-camera (2), and processing means (5) arranged to determine on the basis of the camera-supplied signals the trichromatic components (X, Y, Z) of the colour of the object in a reference colorimetric system (XYZ) using a transfer matrix (M) for switching from the colorimetric system linked to the said acquisition system to the reference colorimetric system and a correction function .GAMMA. of non-linearities of the said acquisition system.
