Abstract: An image processing apparatus includes a first shader configured to perform a light shading operation associated with at least one light source on a three-dimensional (3D) model at a first resolution to obtain a light shading result of the first resolution; a second shader configured to perform a surface shading operation on the 3D model at a second resolution different from the first resolution to obtain a surface shading result of the second resolution; and a processor configured to generate a rendering result by combining the light shading result of the first resolution with the surface shading result of the second resolution.

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.

Abstract: A semiconductor device includes a cell area in which a plurality of memory cells are arranged in an array structure, and a peripheral area in which circuits configured to drive the memory cells are arranged, the peripheral area being next to the cell area. The cell area is divided into a plurality of banks, and the plurality of banks comprise first banks having a base size and second banks having a size of 1/(2*n) (wherein n is an integer greater than or equal to 1) of the base size. The plurality of banks are arranged in a first direction and a second direction perpendicular to the first direction, and the semiconductor device has a shape of a rectangular chip which is elongated in the second direction.
