Abstract: An image processing apparatus and method are provided. The image processing method may generate a mask for preventing a virtual light source from being sampled on an area of a current image frame based on virtual light source information of a previous image frame, applying the mask to the current image frame, sampling the virtual light source in the current image frame to which the mask is applied, and rendering the current image frame based on the virtual light source sampled in the current image frame.

Abstract: A sampler of an image processing apparatus may sample at least one first virtual point light (VPL) from a direct light view. The sampler may sample a second VPL in a three-dimensional (3D) space independent of the direct light view. A calculator may calculate a luminance of the second VPL using a first VPL adjacent to the second VPL selected from among the at least one first VPL.

Abstract: An apparatus and method for encoding a 3D mesh, and an apparatus and method for decoding the 3D mesh are disclosed. The 3D mesh encoding apparatus may determine mesh information including position information of each of vertices constituting the 3D mesh, and connectivity information among the vertices, based on a level, and may progressively encode the determined mesh information based on the level, thereby reducing an error with an original 3D object when compared to an equal transmission rating.
