Patent ID: 8340504

Claim:
An entertainment device for generating augmented reality environments, comprising: an input for a captured video signal; an image analyser arranged to detect a location of a predetermined marker object within said captured video signal; a graphics generator arranged to generate a graphics object for integration with the captured video signal at a selected position, to generate an augmented reality image; a controller arranged to positionally couple the graphics object to the detected location of said predetermined marker object within said captured video signal; and a detection failure logic arranged to signal when the image analyser cannot detect the location of said predetermined marker object within said captured video signal; and in which if the detection failure logic signals that the image analyser cannot adequately detect the location of said predetermined marker object within said captured video signal, then the controller is arranged to positionally decouple said graphics object from a last detected location of said predetermined marker object within said captured video signal; and the controller is arranged to instruct the graphics generator to modify a characteristic of the of the graphics object.
