Abstract
The present invention relates to a method for enabling an image stabilized video. The method comprises providing data defining a vignetting effect for digital image frames captured by a video camera; determining a dislocation value for a digital image frame captured by the video camera; determining, based on the dislocation value, a region of the digital image frame to be displayed in the image stabilized video; applying a vignetting removal process at least on pixels of the digital image frame corresponding to the region to be displayed in the image stabilized video, wherein said applying being based on the data defining the vignetting effect; and reintroducing vignetting on the region of the digital image frame to be displayed in the video based on the data defining the vignetting effect and the dislocation value.
