<P>PROBLEM TO BE SOLVED: To suppress parallel overhead in parallelizing of three-dimensional shape reconstruction calculation. Ž<P>SOLUTION: An image is input from a plurality of cameras (step S101), and the calculation of input silhouette is performed in each calculation node (step S102), and whole reconstruction regions are assigned to all the calculation nodes (step S103), and one reconstruction region is selected as a calculation object in each calculation node (step S104), and whether a calculation node functions as a valid camera or not for the selected reconstruction region is determined in each calculation node (step S105), and the silhouette is transferred from the calculation node of the valid camera to another calculation node (step S106), and the calculation of a visual cone is performed in each calculation node (step S107), and the steps ranging from S104 to S107 are repeatedly performed about all the reconstruction regions, so that the calculation of a whole visual cone can be performed.
