DEVICE AND METHOD FOR CONVERTING DYNAMIC RANGE OF IMAGES Russian patent published in 2018 - IPC G09G5/00 H04N7/00 

FIELD: physics.

SUBSTANCE: image processing device comprises a receiver (201) for receiving an image signal, the second receiver (1701) for receiving a data signal from the display (107), a dynamic range processor (203) configured to generate an output image by applying a dynamic range conversion to the encoded image, and an output (205) for outputting the image output signal to the display. The image signal contains an encoded image. The data signal comprises a data field that contains an indication of a dynamic display range for the display (107) containing a luminance of a white point that is capable of characterizing, whether the display is a high dynamic range display. The processor (203) is configured to apply a dynamic range conversion to an image signal that is a high dynamic range image signal corresponding to an absolute maximum luminance of the target display above 500 nits.

EFFECT: providing the possibility of improved dynamic range conversions that can be adapted to specific characteristics of image visualization.
