Patent ID: RE45152

Claim:
An image processing apparatus for performing processing on a first block for defining a first two-dimensional image and on a second block for defining a second two-dimensional image adjacent to the first two-dimensional image, comprising: a first processing means for performing: horizontal filtering processing on first pixel data in the first block, and vertical filtering processing on second pixel data in the first block; and a second processing means for performing: horizontal filtering processing on third pixel data in the first block, horizontal filtering processing on fourth pixel data in the second block, vertical filtering processing on fifth pixel data in the second block using the third pixel data in the first block after the horizontal filtering processing on the third pixel data in the first block, and vertical filtering processing on sixth pixel data in the second block by using the fourth pixel data in the second block after the horizontal filtering processing on the fourth pixel data in the second block, wherein the second processing means and the first processing means process in parallel ; and a third processing means for performing: horizontal filtering processing on the fifth pixel data in the second block, and vertical filtering processing on the first pixel data of the first block using the fifth pixel data in the second block after the horizontal filtering processing on the fifth pixel data in the second block and the vertical filtering processing by the first processing means .
