1. A method comprising:
coding at least one current block of a first image component with respect to a reference block of at least one second image component, said first and second image components being representative of one and the same scene, said reference block having previously been subjected to coding by partitioning, and then to decoding, said partitioning of the reference block being performed a plurality of times until a determined level (k) (k≧0) of partitioning depth is obtained, said method comprising, before said coding, as a function of the type of the first and second image components:
either partitioning by a coding device the current block to be coded a plurality of times until a level of partitioning depth (k′) dependent on the level of partitioning (k) of the reference block is obtained, by using a dependency relation that is predetermined,
or partitioning by the coding device the current block to be coded on the basis of a level of partitioning depth having been previously initialized by a level of partitioning depth (k′) which depends on the level of partitioning depth (k) for the reference block by using a dependency relation that is predetermined,
wherein partitioning the current block, a plurality of times, is implemented when the first image component is a depth image and the second image component is a texture image associated with said depth image, the current block and the reference block having identical positions in the first image component and in the second image component, respectively.
