Claim 0:
1. A color control system for controlling, in real time, the color of an article positioned on a carrier moving in a given direction of movement, comprising:
an illuminating device configured to illuminate said moving article in successive illuminating cycles, each illuminating cycle comprising successively generating, at a given frequency, a given number N of lines of light having distinct spectral bands, N≥4, said lines of light being substantially perpendicular to the direction of movement, the set of N lines of light generated during an illuminating cycle defining, on the moving article, an illuminating strip of given dimension in the direction of movement;
a detecting device configured to detect, during each illuminating cycle, the light backscattered by the article successively illuminated by each of said lines of light, so as to generate, during each illuminating cycle, for each dot of a number of given dots of an observation strip perpendicular to the direction of movement, a number N of signals corresponding to the light backscattered by said dot in each of the spectral bands, respectively;
a processing unit configured to determine, for each of the dots of the observation strip and on the basis of said N signals, at least one value representative of the color of said dot.
