Abstract
The invention is directed at least in part to a method of illuminating an imager for projecting images, implementing light-emitting diodes of different colors, the diodes being designed to provide a beam illuminating the imager. According to various embodiments of the invention, for a set of at least one imager, the method includes receiving each image of the set; determining a color base dependent on the set of at least one image, called a secondary color base; and dynamically controlling the diodes according to the secondary color base. The invention also relates to a system implementing the method and a projector comprising such a system.
