  • Publication number: 20120162395
    Abstract: Method for filling a hole-region and a three-dimensional (3D) video system using the same. In order to synthesize an image, a plurality of images each having a different viewpoint may be obtained. By using depth maps of the obtained plurality of images, an intermediate virtual viewpoint image may be synthesized. After synthesizing, a hole-region in the intermediate virtual viewpoint image may be filled using a color image of the intermediate virtual viewpoint image, a mask image indicating the hole-region in the intermediate virtual viewpoint image, and a depth image of the intermediate virtual viewpoint image.

  • Publication number: 20120146118
    Abstract: A semiconductor memory device has a memory cell region and a peripheral region. The device includes low voltage transistors at the peripheral region having gate insulation films with different thicknesses. For example, a gate insulation film of a low voltage transistor used in an input/output circuit of the memory device may be thinner than the gate insulation film of a low voltage transistor used in a core circuit for the memory device. Since low voltage transistors used at an input/output circuit are formed to be different from low voltage transistors used at a core circuit or a high voltage pump circuit, high speed operation and low power consumption characteristics of a non-volatile memory device may be.
