Image processing apparatus and image processing program
A course CR is set in a virtual space SP along which a player character CH can move. The player character moves freely on the course, as long as it does not run off the course. In the course, a reference moving path is set indicating a standard moving path of the player character. A camera path of a virtual camera is set along the reference moving path. In the reference moving path, a object corresponding position (CP) is determined corresponding a position (CH(X,Y,Z)) of the player character in the virtual space. A position corresponding to the object corresponding position and a photographing condition are determined for the virtual camera.
