Abstract
The invention relates to a method for processing a video image for a display device. In order to reduce the visibility of transition regions in the processed image, the method comprises a step of application of a third video pattern to at least one part of the image, the third video pattern resulting from the spatial interleaving of a first video pattern and at least one second video pattern according to a determined model.
Claims12
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.
Device for image processing comprising a processor adapted for the generation of a first attenuation function and at least one second attenuation function, wherein said device also comprises:
- means for generating a 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 the first attenuation function and at least one second set of weighting coefficients generated from the at least one second attenuation function,
- said plurality luminous intensity weighting coefficients being generated 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
- means for applying said plurality luminous intensity weighting coefficients to pixels of at least one part of the image.
