An information processing apparatus comprising an image obtaining unit for obtaining a captured image onto which an emission graphic image including a marker serving as a reference is emitted: and a correction information generation unit for generating correction information, for making an emission range and an image capturing range be the same, from a difference between the emission range onto which the emission graphic image is emitted and the image capturing range of the captured image, based on the marker in the captured image and the marker in the emission graphic image.
