Abstract: Disclosed is a method for encoding images of a video sequence that includes implementing the following steps: c) obtaining an initial configuration representative of structural characteristics of a display device and, for an image of the video sequence referred to as the input sub-sequence, d1) carrying out a first spatial sub-sampling operation on the elements of the image by using a filter oriented in a first direction and including a first set of values of sub-sampling factors, the latter being determined as a function of the initial configuration, then inserting the resulting image into an output sub-sequence, and e) encoding the images of the output sub-sequence.
