FIELD: image processing means.
SUBSTANCE: invention relates to image gradations analyzing techniques. Disclosed is method of, at least two image graduations difference analyzing. Method includes stage, at which obtaining first vertical graduated LDR frame with first dynamic range of brightness. Then according to method receiving data coding second graduated HDR frame graduation with second dynamic range of brightness. At that, first and second dynamic brightness ranges are low and high dynamic brightness ranges. Further, according to method determining graduation difference data structure containing characteristic of, at least one area, in which there is difference in graduation between first and second graduated frames.
EFFECT: technical result is enabling of depicted scenes encoding adaptation, providing high-quality images visualization.
