Depiction of images using inverse perspective transformation to provide 3- D effect

摘要

An image, eg of an advertising or promotional nature, is depicted in an inverse perspective form on a playing field (10) for a sporting event. The playing field is imaged by means of a video camera (12) whose line of sight (14) corresponds to the line of sight used in transforming the image to its inverse perspective form, and the output of the camera then broadcast or diffused in a television broadcasting or diffusion service.
