FIELD: data processing.
SUBSTANCE: invention relates to encoding images with an expanded dynamic range. Encoder for encoding input video with an extended dynamic range consisting of a set of images comprises a recalibration unit, a formatting means, an additional calibration unit and a constraint setting unit, performed accordingly. Video decoder for decoding video with an extended dynamic range, consisting of a set of images, comprises a video recovery means, a metadata reading unit, a color processing unit and a logical processor, performed accordingly.
EFFECT: high quality of encoding images.
