FIELD: information technology.
SUBSTANCE: methods and device according to various aspects receive image data in low-dynamic range (LDR) format as input and generate enhanced image data, having a higher dynamic range than the input image data (i.e. high-dynamic range (HDR) image data) as output. In certain versions, the methods are applied to video data and are implemented in real time (i.e. processing video frames for expanding the dynamic range of video frames is carried out, at least on average, at the video signal frame frequency).
EFFECT: real-time expansion of image dynamic range owing to expansion of the dynamic range of low-dynamic range information media.
