Patent ID: 8836695

Claim:
An image processing apparatus, comprising: a processor; a first calculator to calculate first geometry information corresponding to a first pixel and second geometry information corresponding to a second pixel by performing a ray tracing operation with respect to each of the first pixel and the second pixel among pixels constituting an image to be rendered; a second calculator to determine a similarity between the first geometry information and the second geometry information; and a third calculator to calculate third geometry information corresponding to a third pixel adjacent to the first pixel and the second pixel based on the first geometry information and the second geometry information when the first geometry information is determined to be similar to the second geometry information, wherein the first geometry information and the second geometry information include at least one of a position of a pixel, an object identifier (ID) and a normal vector, wherein the similarity is determined based on at least one of the position of the pixel, the object ID and the normal vector, wherein the third geometry information is calculated without performing the ray tracing operation, and wherein at least one of the first calculator, the second calculator and the third calculator use the processor to perform the calculating or determining, wherein the first calculator divides the image into a plurality of blocks, selects the first pixel from a first block among the plurality of blocks, and selects the second pixel from a second block among the plurality of blocks, and wherein a location of the first pixel in the first block is identical to a location of the second pixel in the second block.
