摘要： A method for adjusting moving depths for a video is provided, which is adapted for 2D to 3D conversion. The method includes receiving a plurality of frames at a plurality time points and calculating a plurality of local motion vectors and a global motion vector in each of the frames. The method also includes determining a first difference degree between the local motion vectors and the global motion vector in the frames. The method further includes determining a second difference degree between a current frame and the other frames of the frames. The method also includes calculating a gain value according to the first difference degree and the second difference degree. The method further includes adjusting original moving depths of the current frame according to the gain value. Accordingly, a phenomenon of depth inversion can be avoided or mitigated.

摘要： A depth fusion method adapted for a 2D-to-3D conversion image processing apparatus is provided. The depth fusion method includes the following steps. Respective motion-based depths of a plurality of blocks in an image frame are obtained. An original image-based depth of each of the blocks is obtained. The original image-based depth of each of the blocks is converted to obtain a converted image-based depth of each of the blocks. The motion-based depth and the converted image-based depth of each of the blocks are fused block by block to obtain a fusion depth of each of the blocks. Furthermore, a depth fusion apparatus is also provided.

摘要： An image processing method is disclosed. A 2D image is virtually divided into a plurality of blocks. With respect to each block, an optimum contrast value and a corresponding focus step are obtained. An object distance for an image in each block is obtained according to the respective focus step of each block. A depth map is obtained from the object distances of the blocks. The 2D image is synthesized to form a 3D image according to the depth map.
