IMAGE PROCESSING APPARATUS AND IMAGE PROCESSING METHOD Russian patent published in 2017 - IPC H04N19/117 H04N19/136 H04N19/182 H04N19/80 

FIELD: information technology.

SUBSTANCE: invention relates to images processing. Image processing apparatus comprises: filtration module configured to use a first filter, filtration intensity which is higher than that of second filter, to neighbouring pixels adjacent to horizontal or vertical boundary of units within a decoded image, locally decoded to generate a filtered image; and controller, to control first filter so as to apply to first filter a limitation process using first limiting value, greater than second limiting value of second filter and multiple of second limiting value of second filter.

EFFECT: technical result is improved quality of filtration.
