The method of coding and encoding image sequences includes division of the subassemblies into data blocks to be coded, selection of a first or a second coding mode and division of at least a first reference subassembly in first source blocks, then for each of the data blocks selection of a first predetermined number, determination of a first transformation between the first source blocks selected and the block to code, and in the second mode of coding, the subassembly is coded by relation to itself.- DETAILED DESCRIPTION - The method includes the following stages for each of a group of subassemblies: - division (E31) of the subassemblies into data blocks to be coded (An,m); - selection (E2) of a first or a second coding mode, as a function of a selection criteria; in that the first mode of coding includes for each of the subassemblies for which is has been selected, stages of: - division (E35) of at least a first reference subassembly (gn-1) in first source blocks, then for each of the data blocks to be coded, stages of; -selection (E36) of a first predetermined number of first source blocks (Dn-1,m-1, Dn-1, n-k) in at least a first reference subassembly; -determination (E37) of a first transformation (Tn,m) between the first source blocks selected and the block to code, and in the second mode of coding, the subassembly is coded by relation to itself. An INDEPENDENT CLAIM is also included for a coding device
