IMAGE PROCESSING APPARATUS AND IMAGE PROCESSING METHOD Russian patent published in 2018 - IPC H04N19/117 H04N19/80 

FIELD: computer engineering.

SUBSTANCE: invention relates to computer engineering. Image processing apparatus comprises: a circuit, configured to: decode an encoded stream to generate a decoded image; use a unlocking filter, including a first unlocking filter and a second unlocking filter, the filtration intensity of which is greater, than the filtration intensity of the first unlocking filter, to adjacent pixels adjacent to the block boundary within the decoded image generated by said circuit; and management, as a condition for applying a second unlocking filter, the second unblocking filter for applying the limiting process to the difference value, changed by the second unlocking filter using the second limiting value of the first unlocking filter.

EFFECT: technical result is increased efficiency of unlocking filtration.
