Title:
VIDEO IMAGE DECODING DEVICE, VIDEO IMAGE AND CODING DEVICE, VIDEO IMAGE DECODING METHOD AND VIDEO IMAGE CODING METHOD
Document Type and Number:
WIPO Patent Application WO/2013/108684
Kind Code:
A1
Abstract:
A loop filter section (11) implements class division of local decoded images generated by an adder (9) in coded block units of maximum size determined by a coding control section (2); and designs filters to compensate for superimposed distortion in each local decoded image belonging to each class. Using these filters, filter processing of these local decoded images is implemented. A variable-length coding section (13) codes as filter parameters the class number of each maximum coded block and filter using the local coded image belonging to each class designed by the loop filter section (11).
