PROBLEM TO BE SOLVED: To provide technologies for which any high-grade arithmetic environment is not required, for accurately computing the spatial distribution of a physical quantity on the surface of a mobile in the situation where that distribution changes together with the move of the mobile. SOLUTION: The present invention provides an information processing apparatus for computing the distribution of a physical quantity on the surface of a mobile. The information processing apparatus comprises at least: a first updating means for calculating the position of a nodal point based on the moving direction and moving speed of the mobile and updating the nodal point at the position; a correction means for correcting, when the distance between the nodal point and a reference position corresponding to the nodal point becomes longer than a predetermined length after updating due to the first updating means, the positions of a plurality of nodal points just for the integer multiple distance of a reference interval reversely to the moving direction so that the distance becomes shorter than or equal to the predetermined length; and a second updating means for updating a physical quantity corresponding to the corrected nodal points at the positions of the non-corrected nodal points using the physical quantity corresponding to the nodal point of which the position is corrected for each of the corrected nodal points.
