FIELD: information technologies.
SUBSTANCE: low-pass filter is used to filter interpolated video data where extent of filtering by low-pass filter is determined on the basis of boundary strength value determined for interpolated video data and adjacent video data (interpolated and/or not interpolated). Boundary strength is determined on the basis of control video data proximity for interpolated video data and adjacent video data.
EFFECT: noise reduction for interpolated data and reduction of interpolation distortion.
