In this video sequence we illustrate an application of the proposed zoom dependent lens distortion model to a real soccer video sequence. We have corrected the lens distortion and we can observe the variation of the lens distortion models with respect to the focal distance f looking at the curvature of image boundary: for large  focal distance, the lens distortion correction is significantly smaller than for small focal distance. We acknowledge MEDIAPRODUCCION S.L. company who has kindly provided to us with the real soccer video sequence we use in this experiment.
