  • Image processing circuit and image processing method
    Patent number: 8923643
    Abstract: An image processing circuit and an image processing method are disclosed. The image processing circuit comprises a block matching unit, a multiplexer, an arbiter, and a motion compensation circuit. The block matching unit calculates an alternating current (AC) sum of absolute difference (SAD) and a direct current (DC) sum of absolute difference (SAD) according to a current block in a current image and a reference block in a reference image. The arbiter controls the multiplexer selectively to output the AC SAD or the DC SAD according to an arbitration rule related to a scene characteristic of the current image. The motion compensation circuit executes motion compensation according to the AC SAD or the DC SAD outputted by the multiplexer.

  • Depth generation method and apparatus using the same
    Patent number: 8718402
    Abstract: A depth generation method adapted for a 2D to 3D image conversion device is provided. The depth generation method includes the following steps. Motion vectors in an image frame are obtained by motion estimation. A global motion vector of the image frame is obtained. Motion differences between the motion vectors of each block and the global motion vector are calculated. A depth-from-motions of each block is obtained based on the motion differences. Furthermore, a depth generation apparatus using the same is also provided.
