DEVICE OF IMAGE PROCESSING AND METHOD OF IMAGE PROCESSING Russian patent published in 2012 - IPC H04N7/32 

FIELD: information technologies.

SUBSTANCE: image coding device determines a basic factor of quantisation (QP_mb), serving as a predictable quantisation factor in case, when a generated code of the main coding approaches the target size of the code during coding of the input image. The image coding device codes the input image for each increment during control with feedback by performance of quantisation with the help of an adapted quantisation parameter (QPt) on the basis of an average parameter.

EFFECT: invention provides for compression of a generated code size for each image increment below the target size of a code in a proper manner without use of a quantisation factor serving as the basis for a quantisation pitch, with high deviation.
