Abstract:
1. A game processing apparatus arranged to receive successive images from a video camera and to initiate a game control function in response to a user obscuring a lens of the video camera for at least a predetermined time period, the apparatus comprising: means operable to detect an average luminance of each successive image received from the video camera; means operable to identify that the user has covered the lens of the video camera by detecting whether the average luminance of each of a group of successive images received from the video camera in respect of the predetermined time period is lower than a threshold luminance value, the lens of the video camera being within a lens housing, the housing protruding beyond the lens so that light may be substantially prevented from reaching the lens by the user placing a finger over the lens housing without that finger touching an optical surface of the lens; and means operable to initiate the game control function of the game processing apparatus in response to detection that the average luminance of each of the group of successive images received from the video camera is lower than the threshold luminance value.
