摘要

This image encoding method includes: a restriction information generation step (S140) in which tile restriction information, which indicates whether or not any restriction is imposed on processing of multiple tiles that are obtained by dividing a picture, is generated, and the tile restriction information is encoded; and a determination step (S142B) in which when the tile restriction information indicates a restriction on the processing (Yes in S141), whether or not filter processing should be executed of multiple tile boundaries is determined on the basis of filter information that indicates whether or not the filter processing should be executed of one tile boundary among the multiple tile boundaries.
