DEVICE AND METHOD OF IMPROVING PERCEPTUAL LUMINANCE NONLINEARITY-BASED IMAGE DATA EXCHANGE ACROSS DIFFERENT DISPLAY CAPABILITIES Russian patent published in 2017 - IPC H04N19/40 G06K9/36 H04N19/124 H04N19/115 

FIELD: information data.

SUBSTANCE: invention relates to image data exchange. Method of recoding reference encoded image data into image data typical for device comprises steps of: determining display of digital code between a set of values of reference digital code and a set of values of digital code typical for device; receiving reference encoded image data, encoded by a set of values of reference digital code, wherein brightness value in reference encoded image data are based on a set of values of reference digital code, and a set of values of reference digital code is based on maximum contrast sensitivity of human vision, adapted to specific levels of illumination; decoding based on displaying digital code reference encoded image data, encoded by a set of values of reference digital code, into image data, typical for device, encoded by a set of digital codes typical for device.

EFFECT: technical result is displaying reference encoded data with fewer errors.
