Abstract
Provided is an image processing apparatus that may determine whether indirect lights are to be assigned to tiles for tile-based deferred rendering. For example, the image processing apparatus includes a calculator configured to calculate a correlation based on at least one of a first vector representing an object normal direction of a tile to be rendered and a second vector corresponding to a normal vector of an indirect light to be determined to be assigned to the tile, and a determiner configured to determine whether the indirect light is to be assigned to the tile by comparing the correlation to a threshold value.
