  • Image process device, image process method, and image process program
    Patent number: 8971611
    Abstract: A mask correcting unit corrects an externally set mask pattern. A depth map processing unit processes a depth map of an input image for each of a plurality of regions designated by a plurality of mask patterns corrected by the mask correcting unit. An image generation unit generates an image of a different viewpoint on the basis of the input image and depth maps processed by the depth map processing unit. The mask correcting unit performs a blurring process on an object boundary part of the mask pattern.

  • QUANTUM STATE TRANSFER METHOD, QUANTUM STATE TRANSFER SYSTEM DEVICE, QUANTUM OPERATION METHOD AND QUANTUM OPERATION APPARATUS
    Publication number: 20110153257
    Abstract: A quantum state transfer system device comprises transmitting device that measures an input qubit and a first qubit array that includes not less than three qubits; and a receiving device that selects in accordance with the measurement result a qubit as an output qubit from among qubits included in a second qubit array that includes not less than three qubits and is quantum-mechanically entangled with the first qubit array.

  • Magnetic signal transmission line
    Patent number: 7724558
    Abstract: A magnetic signal transmission line includes a one-dimensional array of a plurality of single-magnetization domains each formed in a ferromagnetic body. The anisotropic energy of the single-magnetization domains is zero to 120% of the interactive energy acting between dipoles in adjacent single-magnetization domains. The single-magnetization domains are formed by sputtering iron onto a silicon substrate by using a mask.

  • BLIND SIGNATURE METHOD AND ITS SYSTEM
    Publication number: 20090031137
    Abstract: Signature requestor terminal device (10) codes a plurality of messages to a quantum state and transmits it to signer terminal device (20). Signer terminal device (20) issues a blind signature for the plurality of the messages coded to the quantum state, codes the messages and the signature to a quantum state and sends them back to signature requestor terminal device (10).
