US Patent 11176866 Image processing method based on peripheral reduction of contrast

An object of the invention is to avoid or at least limit the aforementioned drawback by a specific processing of video images to display, notably on large size screens. For this purpose, a method for processing at least one image of a video sequence is described. The method includes defining at least two peripheral areas PL, PR in the at least one image, and reducing contrast of pixels in the defined peripheral area(s) having a local contrast RL and/or RD above a local contrast threshold Rth or reducing contrast of pixels in subregions 1, 2, . . . , i, . . . , N of these defined peripheral areas having a local contrast Ri, R′i above a local contrast threshold Ri-th.
