An interactive video game system. An image input device produces consecutive images including a participant in a field of view. A luminance processing device obtains a luminance change of a current image in accordance with the consecutive images, wherein the luminance change indicates an active region of the participant. A field hit checker and a motion detector check if the active region ranges in a digital region or compute a motion and direction of the active region in accordance with the luminance change of the current image and a digital information, thereby generating an output signal. A rendering engine controls a sprite image in accordance with the output signal and accordingly displays the result on a display. Thus, the participant can play an interactive video game.
