Abstract: An image processing apparatus to calculate a visibility with respect to a plurality of virtual point lights (VPL) sampled at a three-dimensional (3D) model includes at least one first VPL included in a screen scene associated with a viewpoint to render and at least one second VPL not found in the screen scene, and may calculate a first probability obtained by calculating a visibility between a first area including the first VPL and a first point with respect to the at least one first VPL.
