A technique for detecting an abnormal behavior by monitoring moving objects such as human being and a car. The place where the abnormal behavior of the moving objects occurs is deduced from the position of the moving object and the direction in which the moving object moves and presented to the car. An abnormal detector comprises means for determining the position of the moving object and the direction in which the moving object moves, means for determining the place where an abnormal incident causing an abnormal behavior of the moving object occurs on the basis of the determined position and direction, and means for displaying the place where the abnormal incident occurs. Therefore it is possible to immediately know the cause of the abnormal behavior of the moving object from the video information collected by observation monitoring moving objects such as a human being and a car.

A graphics processor comprises: a light source table holding light source data; a conversion unit for converting the light source data to be set in the light source table from a float type (single-precision floating point real number type) into an int type (integer type); an inner product calculation unit for calculating the inner products of normal directions, light source directions and sight line directions at the vertices based on the light source data; and a color calculation unit for performing light source computations based on the calculated inner products to determine the colors of the vertices.

A graphics system utilizes the graphics standardization specification PEX for providing high-speed drawing when a client and a server locally operate on the same machine and allow an application to change structure and graphics attributes defined by another application without being aware of the distinction between local and remote cases.
