FIELD: information technologies.
SUBSTANCE: there proposed is method and device for reading motion picture film grain structures in raster sequence when imitating the grain of motion picture film including the setting of pseudo-random initial position, repetition of pseudo-random initial position for each line of the motion picture film grain block group and use of the other pseudo-random initial position for each line of presentation of the following group of motion picture film grain blocks. In various design versions of this invention, other pseudo-random initial positions are initiated by means of repeated setting of at least one reference value of pseudo-random number generator made for determining the above pseudo-random initial positions.
EFFECT: reducing the film grain imitation complexity in the picture and providing the possibility of interpreting the information message of additional improvement of motion picture film grain.
