Claim:
1. A method for enabling an image stabilized video, the method comprising: 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, wherein the dislocation value is a dislocation of the entire digital image frame or a dislocation of one or a few rows of the digital image frame, the dislocation being induced by camera movement; applying a shift on the digital image frame in accordance with the determined dislocation value to compensate for movement of the video camera; cropping the digital image frame based on the dislocation value forming a cropped image frame, wherein the cropped image frame corresponds to 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 of the vignetting removal process is based on the data defining the vignetting effect; 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; and displaying the region of the digital image frames to be displayed as part of the image stabilized video.
