Abstract: The present invention relates to an image processing device arranged for image stabilization of a video stream comprising image frames captured by a video camera, the image processing device comprising: an electronic image stabilization module arranged to perform electronic image stabilization to sub-sets of image frames of the image frames of the video stream to compensate for a oscillating movement of the video camera; and a masking module arranged to apply an edge mask to each sub-set of image frames, wherein each edge mask is having a fixed width, wherein the fixed width is based on a camera oscillation amplitude being specific for the sub-set of image frames to which the edge mask is applied. The present invention also relates to a method for image stabilization of a video stream.
