3D processing techniques are really promising. However, several hurdles have to be overcome. In this paper, two of them are examined. The first is related to the high disparity management. It is currently not well mastered and its impact is strong for viewing 3D scene on stereoscopic screens. The second concerns the salient regions of the scene. These areas are commonly called Region-Of-Interest (RoI) in the image processing domain. The problem appears when there are more than one region-of-interest in a video scene. Indeed, it is then complicated for the eyes to scan them and especially if the depth difference between them is high. In this contribution, the 3D experience is improved by applying some effects related to RoIs. The shift between the two views is adaptively adjusted in order to have a null disparity on a given area in the scene. In the proposed approach, these areas are the visually interesting areas. A constant disparity on the salient areas improves the viewing experience over the video sequence.
