<p>This invention generally relates to the detection and correction of rolling shutter artefacts in video sequences. The proposed solution determines wobble line detector(s) in order to detect and correct rolling shutter wobble in a video sequence. It is taken advantage of the fact that the analysis of the motion vector field or the homography transformation can help detecting rolling shutter wobble in a video sequence. This way the proposed apparatus is able to provide a simple mechanism to detect wobble and to provide the relevant distortion correction processing. Indeed, it is thus possible to enable wobble correction only when wobble has been detected. In the proposed solution, correction depends on the detected wobble line(s).</p> |
