Abstract
The image coding method for improving the filtering quality and suppressing increase in the transmission bandwidth includes: selecting filter data elements of the first and second component filters from a filter memory (), and obtaining indexes stored in association with the selected filter data elements in the filter memory () (S, S); coding a macroblock using the two filter data elements (S); adding the two indexes to a coded video signal (S); calculating the filter data elements of the first and second component filters based on a slice, and assigning indexes to the filter data elements (S, S); storing, in the filter memory (), a corresponding one of the calculated filter data elements and the index in association with each other for each of the component filters (S); and adding the two calculated filter data elements to the coded video signal (S).
