Patent ID: 8610707

Claim:
A three-dimensional (3D) imaging system, comprising: a motion estimation and motion compensation (MEMC) unit configured to perform the motion estimation (ME) and the motion compensation (MC) on a reference frame and a current frame, thereby generating an MEMC generated frame and motion vector (MV) information, wherein the reference frame is displayed as a first 3D image; a depth controller configured to partition the reference frame into multiple regions according to the MV information, thereby generating depth information; a scene-mode depth generator configured to generate a depth map according to the reference frame and the depth information; a depth-image-based rendering (DIBR) unit configured to generate a scene-mode generated frame for a second 3D image according to the reference frame and the depth map; and a mode decision unit activated or inactivated the depth controller according to the MV information; wherein the mode decision unit outputs one of the MEMC generated frame and the scene-mode generated frame as the second 3D image; wherein the mode decision unit outputs the scene-mode generated frame as the second 3D image when the MV information indicates that a relation between the current frame and the reference frame is substantially standing still; otherwise, the mode decision unit outputs the MEMC generated frame as the second 3D image.
