SYSTEMS AND METHODS FOR COMPENSATION OF AMBIENT LIGHTING USING DISPLACEMENT PQ Russian patent published in 2024 - IPC G09G5/10 G09G3/34 

FIELD: computer engineering.

SUBSTANCE: invention relates to computer engineering and specifically to methods and systems for compensating for ambient lighting around displays. Offset of the PQ curve is applied to the image, which can compensate for suboptimal ambient lighting conditions for the display, wherein the offset PQ is or addition with the compensation value in the PQ space, followed by the subtraction of the compensation value in the linear space, or addition with compensation value in linear space with subsequent subtraction of compensation value in PQ space, additional corrections of PQ curve are performed.

EFFECT: high image quality with respect to image brightness in various ambient lighting situations.
