FIELD: physics, video.
SUBSTANCE: invention relates to image processing means. The method includes creating a plurality of frames of a picture and related prediction reference frames; for each frame and related prediction reference frame, calculating the intensity value and the colour value in a first colour domain; for each frame and related prediction reference frame, calculating weighted prediction gains; if said gains are non-negative, determining that a global transition with zero offset is occurs in a second colour domain; and if not all of said gains are non-negative, determining that a global transition with gradual change in illumination does not occur.
EFFECT: high efficiency of an image display means when encoding and processing video.
