Abstract
Each color image is decomposed into at least one series of at least three successive primary images of different primary colors which are successively displayed by modulating the activation duration of the pixels of an imaging device. According to the invention, the distribution of the pixel activation phases in the three successive subframes is contracted: the pixel activation periods of the first primary image are shifted toward the end of the subframe of this first image, and, during the subframe of the third primary image, the pixel activation periods of this third primary image are shifted toward the beginning of the subframe of this third image. Color break-up faults are thus advantageously reduced.
