IMAGE PROCESSING DEVICE AND IMAGE PROCESSING METHOD Russian patent published in 2018 - IPC H04N19/30 H04N19/124 

FIELD: image processing means.

SUBSTANCE: invention relates to image processing. Image processing apparatus comprises: a control unit configured to be mounted, based on the first scaling list for the first layer, the second scaling list for the second layer decoded with reference to the first layer; and a quantization unit configured to quantize the second layer conversion coefficient data using a second scaling list set by the control unit.

EFFECT: increased efficiency of image coding by reusing the quantization parameters at different levels.
