Abstract: A method for realistically implanting a non-floating. Computer Graphic Image object into a real camera image sequence filmed scene, and for obtaining roaming capabilities therein, including modeling a picture into which a Computer Graphic Image object is to be implanted by creating therefor imaginary borders, providing a three-dimensional vector representing the movement of the camera between each frame, and expanding said vector to a plane by calculating the movement of the camera while marinating its original angles; and therewith by respectively using an imaginary camera to render a 3D object on a screen of a computer and by respectively coordinating the filming camera's angle with the imaginary camera for implanting the Computer Graphic Image object in the image sequence filmed scene; wherein the method is characterized by implementing angular noise from the filming camera's angle to the object rendered by the imaginary camera.
