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.
