  • Patent number: 7126643
    Abstract: Provided is a progressive scan method used in a display using adaptive edge interpolation. According to the progressive scan method, a final edge direction that satisfies a first edge-determination condition and a second edge-determination condition is detected by performing interpolation for 7×3 pixel windows, using code determination and a comparison of a standard deviation based on differences between luminances of pixel data divided by an edge boundary. As a result, directional edge interpolation is carried out in a region of a low gradient below 45° and to 27° at the minimum, and simple intra-field linear interpolation can be performed in a high-frequency texture region. Subsequently, it is possible to remove high-frequency noise introduced in edge dependent interpolation or unnatural screen display due to zigzagged edges, thereby improving the quality of a display.

    Abstract: A method of capturing data that are transferred in synchronization with a data strobe signal. The method includes sampling a data strobe signal at a clock frequency higher than a data rate to detect a transition point of the data strobe signal (e.g., by generating and comparing a plurality of sampled data strobe signals), and sampling data to generate sampled data, and selecting reliable data among the sampled data based upon the transition point. A data capture circuit that captures data transferred in synchronization with a data strobe signal, includes a data strobe signal sampling circuit, a data sampling circuit, and may further include a transition position-indicating signal (case) generator and a data selection circuit.

  • Publication number: 20060164708
    Abstract: An optical pickup device according to an embodiment of the present invention comprises a light source for projecting a beam of light to record and reproduce information with respect to an optical recording medium. A collimating lens is disposed on a path of the light to converge and convert the light into a parallel beam. An object lens condenses the parallel beam from the collimating lens and projects the parallel beam onto the optical recording medium. An optical element is disposed between the collimating lens and the object lens. A first actuator moves the collimating lens along the optical axis to thereby control a distance between the collimating lens and the optical element. A first controller drives the first actuator to find a position for the collimating lens, for reducing aberration generated in the light being projected to the optical recording medium. Accordingly, the aberration can be effectively prevented, thereby improving recording and reproducing performance of the optical pickup device.
