UNIVERSAL CORRECTION OF IMAGE BLOCKING EFFECT Russian patent published in 2013 - IPC H04N7/30 G06T9/00 

FIELD: information technologies.

SUBSTANCE: device comprises a processor arranged as capable of realisation of a set of commands for calling a facility of intracycle filtration of blocking effect deletion and for universal correction of blocking effect in a decoded output signal during operation of a post-cycle filtration using the facility of intracycle filtration of blocking effect deletion, at the same time the universal correction of blocking effect includes the following: performance of an operation of strong filtration in respect to units in a decoded output signal for correction of an inherited blocking effect, at the same time units contain missed macrounits and units with a template of a coded unit, equal to zero, and inclusion of a facility of intracycle filtration of blocking effect removal for edges of a fragment of an image of fixed size, which are not arranged on the border of the unit of the appropriate intermediate macrounit, for correction of the inherited blocking effect; and a memory connected to the processor.

EFFECT: development of a method of universal correction of blocking effect, including inherited blocking effect.
