FIELD: image processing means.
SUBSTANCE: group of inventions relates to high dynamic range image processing (HDR) technologies. Method for detecting changes to the base layer when decoding an HDR image is proposed. Method comprises the step of: receiving the base layer data for the HDR image, the base layer data can be changed by an existing image viewer. Next, the first checksum parameter in the ASCII mapping for the base layer data contained in the marker segment APP11 is received, the first checksum being used by the HDR decoding device and ignored by the existing image viewer. Accept the residual relationship data for the HDR images contained in the APP11 segment of the marker.
EFFECT: technical result is to detect the presence of changes in the base layer when processing HDR images.
