A device for coding still images, wherein the still images are segmented into homogeneous regions whereto a specific label is attached. The contents and the contours of the regions are coded by circuitry including a sub-assembly (30) for coding contour information which itself includes a contour detector. On the contours of each region the real direction of orientation on the type of contour edge retained for the transmission is detected, and tested by comparing, for each pair of successive image points of each contour segment, the real direction of orientation thus detected and the instantaneous direction of orientation between these two points. The device further includes circuitry for coding segments traversed in the detected real direction of orientation, and for re-initializing the entire procedure for each of the regions.
