1. A coding method comprising:
coding a current image split up into blocks, said current image containing at least two distinct first and second zones of blocks which do not overlap and are defined previously to the coding of any block of said current image, wherein a block of the first zone is located to the left of a block of the second zone, and wherein said coding comprises the following acts performed by a coding device:
coding the block of said first zone, by:
predicting the block of said first zone by using the block of the second zone that has been previously coded and then decoded, and
coding an item of information which indicates if a mode of prediction Intra Block Copy has been used or not to predict the block of said first zone;
decoding the coded block of the first zone; and
storing data of the decoded block of the first zone as a function of the item of information that has been coded.
