Reduction in the blockiness of a simulated film grain block can be achieved either by the use of adaptive downscaling or adaptive deblocking filtering to adjust the intensity of the pixels at the block edge in accordance with at least one film grain block parameter, such as film grain size, intensity and texture. Performing such adaptive downscaling or adaptive deblocking filtering achieves improved performance at lower computational cost by avoiding modification of film grain block pixels in lesser affected areas.

La réduction de l'effet de blocs d'un bloc de grains de films simulé peut être obtenue, soit en utilisant une réduction d'échelle adaptative, soit par filtrage de déblocage adaptatif, en vue d'ajuster l'intensité des pixels à l'arête du bloc, en conformité avec au moins un paramètre de bloc de grains de films, tel qu'une taille, une intensité et une texture de grains de films. En effectuant une telle réduction d'échelle adaptative ou un filtrage de déblocage adaptatif, on obtient des performances améliorées, pour des frais de calcul peu élevés, tout en évitant la modification de pixels de blocs de grains de films dans moins de zones affectées.
