  • photographing means for photographing a predetermined area in which said object moves, at intervals of time T;

    projecting means for projecting brightness information of each pixel in an image photographed at said intervals of time T by said photographing means, onto an axis along a moving direction of said object, and for accumulating each brightness value on said axis to generate one-dimensional projected information;

    storage means for storing said one-dimensional projected information from said projecting means; and

    detecting means for detecting said velocity of said object moving in said predetermined area by using a plurality of pieces of said one-dimensional projected information stored in said storage means.
