FIELD: physics.
SUBSTANCE: loop filter 6 includes a region classification unit 12 for extracting an estimate value of each of the regions which make up a local decoded image in order to classify each of the regions into a class belonging to the region, according to the estimate value, and a unit 13 for forming and processing a filter for each class belonging to one or more regions from the regions which make up the local decoded image, forming a Wiener filter which minimises the error arising between the input image and the local decoded image in each of the one or more regions belonging to a class, in order to compensate for the distortion on the one or more regions using the Wiener filter.
EFFECT: high image quality.
