Information processing system for superimposing a virtual object on a real space correcting deviations caused by error in detection of marker in a photographed image.

摘要

An information processing section of a game apparatus executes a program which includes: acquiring a real world image; setting the most recent view matrix of a virtual camera based on a detected marker (S204); reading the previous view matrix (S206); calculating correction view matrixes so as to change a blending ratio at which the most recent view matrix is blended depending on a distance (S208 to S210); selecting the correction view matrix such that the longer the distance between an object and the marker is, the lower the blending ratio is; and rendering a virtual object in a frame buffer in a superimposed manner by using the selected correction view matrix.
