DEVICE AND METHOD OF IMPROVING PERCEPTUAL LUMINANCE NONLINEARITY-BASED IMAGE DATA EXCHANGE ACROSS DIFFERENT DISPLAY CAPABILITIES Russian patent published in 2018 - IPC G09G5/10 G06T1/00 G06F17/10 

FIELD: exchange of image data.

SUBSTANCE: invention relates to image data exchange. Method for exchanging image data based on non-linearity of perception, performed by at least one computing device, in which: D value of the digital code of the luminance perception curve for the red component for the image is received; determine the normalized value V of the signal of the perception curve from the D value of the digital code of the luminance perception curve; normalized value Y of the luminance component for the red component is determined on the basis of the functional model and determining the absolute value L of the brightness from the normalized value Y of the luminance component.

EFFECT: technical result is to provide improved image data exchange based on non-linear perception between devices with different display capabilities.
