Abstract (en)
[origin: FR2857814A1] The device has colored rotating wheels (12, 14) to generate a periodic colored beam (8), and an imager (16) modulating the beam based on a received video signal. The beam has, successively at each period, a set of base colors (alpha , beta , gamma ) in synchronization with the images generated by the imager for each base color. The adjustment of the position of the wheels allows modification of the shades of the colors.
