Abstract:
1. An apparatus for capturing video footage of at least one moving object, on a racecourse or sporting field, the video footage including sequential still pictures each containing a respective image of said at least one moving object, the apparatus comprising: at least one camera mounted on a pan tilt head being configured to follow the movement of said at least one moving object, to thereby capture said video footage; and a controller in communication with the pan tilt head, for controlling the pan and tilt thereof, the controller being used to set the position of a first and a second biasing means with respect to the limits of a picture frame of said at least one camera, wherein the first and second biasing means are ordered hierarchically by the controller, wherein the position of the image of said at least one moving object with respect to the camera's picture frame, is influenced by both said first and second biasing means, to control the position of said image of the at least one moving object within said sequential still pictures captured by the camera, said first biasing means having precedence over said second biasing means when determining the position of said image, the movement of said pan tilt head or heads being controlled to obtain video footage, such that the position of the image within one of said sequential still pictures is biased towards, or away from, the position of said first or second biasing means with respect to the position of said image of the moving object in a preceding still picture of said sequential still pictures.
