  • Publication number: 20090051818
    Abstract: A video signal processing device includes a sample data register to hold a signal level of a video signal after correction at each sample point as a correction level, a coefficient operation circuit to output a first coefficient, a coefficient selection circuit to output a second coefficient, and an interpolation operation unit to calculate a signal level of a video signal after correction corresponding to a signal level of the input video signal by using the correction level held in the sample data register, the first coefficient or the second coefficient and performing the cubic interpolation operation or the linear interpolation operation. The first coefficient is used when a video signal after correction is obtained from the input video signal by a linear interpolation operation. The second coefficient is used when a video signal after correction is obtained from the input video signal by a cubic interpolation operation.

  • Patent number: 7486598
    Abstract: A playback apparatus plays back data from a recording medium having recorded thereon a file system representing association between identification information for identifying a file and a position where the file is recorded, pieces of segment data constituting the file, and markers for the respective pieces of segment data, each marker that is recorded after a key marker specified in certain cases including location information of the key marker. The playback apparatus includes a detector that detects a last marker in a recording area where data has been recorded on the recording medium but has not been reflected on the file system, and a restoration processor that executes a restoration process of reflecting on the file system segment data that has been recorded on the recording medium but has not been reflected on the file system, based on the location information of the key marker and the location information of segment data.

  • Publication number: 20080277583
    Abstract: Electrification affected on a surface of a sample which is caused by irradiation of a primary charged particle beam is prevented when plural frames are integrated to obtain an image of a predetermined area of the sample in a charged particle beam apparatus. The predetermined area of the sample is scanned with a primary electron beam from an electron gun, and plural frames are generated and integrated while detecting generated secondary electrons with a detector to obtain the image of the predetermined area. If it is determined by a detection signal of the detector that an electrification amount at the predetermined area becomes a specified value when generating plural frames, an electricity removal voltage is applied to a boosting electrode to remove or reduce the electrification, prior to generation of the next frame. Accordingly, the signal-to-noise ratio of the image obtained by integrating plural frames can be improved.
