  • Patent number: 8345759
    Abstract: A prediction error generating unit generates a predictive vector from the motion vectors of a plurality of adjacent blocks, and obtains a difference from a target vector. A plurality of variable-length coding units respectively encode the output of the prediction error generating unit with different encoding methods. A determining unit estimates the accuracy of the predictive vector generated by the prediction error generating unit based on the degrees of non-uniformity of the motion vectors of the plurality of adjacent blocks. A selecting unit selects one of the encoding results obtained by the plurality of variable-length coding units.

  • Patent number: 8345351
    Abstract: A microscope system which can improve the ease of use and the observation environment when a sample is observed using a microscope formed of a stand and a main body which is removable from the stand. A microscope is formed of a main body and a stand, and the main body is removable from the stand. The main body includes an objective lens, an image optical system, a CCD, a compact monitor and a battery, so that the main body, when removed from the stand, can function independently as a microscope. If the main body is mechanically connected to the stand, the main body and the stand are electrically connected via connectors, and an observation image captured by the CCD is supplied from the main body to the stand via the connectors, and is displayed on a monitor.

  • Patent number: 8340472
    Abstract: In a pixel interpolation apparatus for interpolating pixels, an edge pixel detection unit detects edge pixels constituting an edge among pixels on lines positioned above/below the interpolation pixel. A continuous edge detection unit detects edge pixels in which two pixels or more consecutively line up among edge pixels detected by the edge pixel detection unit as a continuous edge. A continuous edge pair detection unit determines the combination of the continuous edges detected on each of the lines above and below the interpolation pixel among the continuous edges detected by the continuous edge detection unit. An edge direction determination unit determines the edge direction of the interpolation pixel on the basis of the positional relation of one set of continuous edges determined by the continuous edge pair detection unit. An interpolation pixel calculation unit calculates an interpolation pixel using the edge direction determined by the edge direction determination unit.
