3-D digital image processor and method for visibility processing for use in the same
First Claim
1. A method for processing a visibility for use in a displaying procedure of a three-dimensional (3-D) digital image, comprising steps of:
- presetting a depth map according to a plurality of pixels received, said depth map storing said pixels and reference depths corresponding thereto; and
receiving a pixel data and proceeding a visibility test with reference to said depth map, thereby determining whether to proceed a rendering operation on said 3-D digital image by said pixel data.

Abstract
A three-dimensional (3-D) digital image processor and a method for processing a visibility for use in a displaying procedure of a 3-D digital image are disclosed. The 3-D digital image processor includes a depth map generator, a memory device and a rendering engine. The method includes steps of presetting a depth map according to a plurality of pixels received, the depth map storing the pixels and reference depths corresponding thereto, and receiving a pixel data and proceeding a visibility test with reference to the depth map, thereby determining whether to proceed a rendering operation on the 3-D digital image by the pixel data.

7. A three-dimensional (3-D) digital image processor comprising:
-
a depth map generator presetting a depth map according to a plurality of pixels received, wherein said depth map stores a corresponding relation between two-dimensional (2-D) coordinates and depth values of said pixels;
a memory device in communication with said depth map generator for storing said depth map therein; and
a rendering engine receiving a pixel data and proceeding a rendering operation on a corresponding pixel of said 3-D digital image, said rendering engine proceeding a visibility test with reference to said depth map stored in said memory device, thereby determining whether to proceed said rendering operation on said 3-D digital image by said pixel data. - View Dependent Claims (8, 9, 10, 11, 12, 13)
