Provided is image processing technology capable of avoiding image degradation even when a luminous body model is expanded on a three-dimensional virtual space. This image processing method generates a two-dimensional image obtained by performing perspective projection to an image model disposed in a virtual three-dimensional space on a perspective view plane 14 in a view coordinate system of a view point 12 set in the virtual three-dimensional space. The luminous body disposed in the virtual three-dimensional space is configured from a model 18 having a distance component Z in the direction from the luminous source coordinate toward the view plane, and having a cone shape extending in a direction intersecting with the direction in the view plane side, and the center image of the luminous body and the diffused light image emitted therefrom are drawn on the object.
