Abstract: A data processing device comprises an analyser to analyse successive images captured by a camera and to detect an optically detectable marker in the captured images, a first location detector to detect a location of the optically detectable marker with respect to a location of the camera according to a first detection mode and to generate a first detection result, a second location detector to detect the location of the optically detectable marker with respect to the location of the camera according to a second detection mode different to the first detection mode and to generate a second detection result, and a processor to select at least one of the first detection result and the second detection result and to generate data indicative of the location of the optically detectable marker with respect to the location of the camera based on the selection.
