1. A processing device for image frame stabilization of a digital video sequence, comprising processing means provided, for each image frame of a video sequence, for determining a jitter from global motion parameter(s) of said image frame, determined from a motion estimation between said image frame and the preceding one of said video sequence, and removing said jitter from said determined global motion parameter(s) for removing unwanted motion(s) present into said image frame, characterized in that said processing means arranged for determining a type of motion present in said video sequence from the determined global motion parameters of said image frame and the ones of at least one preceding image frame of said video sequence, then for selecting a chosen jitter extraction technique amongst at least two jitter extraction techniques depending on said determined motion type, and for using said chosen jitter extraction technique to determine said jitter.
