A method comprises displaying an augmented reality (AR) or modified representation of a target element, such as a marker 104, in a field of view of an image capture device and transitioning to a stored modified representation of the element 106, such as a 3D overlay, upon detecting that it has left the field of view. A device such as a hand held device may calculate or retrieve a transformation matrix of the overlay at a point before the target was lost, when the camera last detected the target element and provide a smooth visual transition from the last calculated transformation matrix to an identity matrix to render the overlay in the plane of and fitted to the screen of the device. |
