1. Method for processing an image from a video for a display device, wherein the method comprises a step of application of a plurality luminous intensity weighting coefficients to pixels of at least one part of the image in a way to conserve a maximum luminous intensity in at least one region of said at least one part of the image and to attenuate the luminous intensity in the rest of said at least one part of the image, said plurality luminous intensity weighting coefficients resulting from the spatial interleaving, according to a determined interleaving model, of a first set of weighting coefficients generated from a first attenuation function and at least one second set of weighting coefficients generated from at least one second attenuation function.
