A method for composing a multilayer video image of which the values of the pixels of the image layers are stored in a memory. The video image may include at least one first image layer and a second image layer located in front of the at least one first layer and having an opaque area. The method may include defining a region of the at least one first image layer to be hidden by the opaque area, reading from the memory the stored pixel values, with the exception of the values of the pixels of the region of the at least one first image layer, and composing the video image at least from the read pixel values.
