A processing device (D) is dedicated to image frame stabilization of digital video sequences in an electronic equipment (E1), such as a digital camera, for instance. This processing device (D) comprises processing means (PM) arranged, for each current image frame of a video sequence, for determining a type of motion present in the video sequence from global motion parameters of the current image frame and the ones of at least one preceding image frame of this video sequence. These parameters are determined from a motion estimation between the current image frame and the preceding one of the video sequence. The motion determination is followed by a selection of a jitter extraction technique amongst at least two jitter extraction techniques depending on this determined motion type. The jitter extraction technique thus chosen is used to determine a jitter intended to be removed from the determined global motion parameter(s) in order to remove unwanted motion(s) present into the current image frame.
