  • Patent number: 8401333
    Abstract: When different images are combined, the corresponding parts are to be aligned accurately. To thus combine images, the feature point of each pixel is calculated from each original image using an operator (filter). The pixels are divided into blocks that the resolution matches that of the reduced image of each original image, and an expectation value map for registering the expectation value of the feature point of each block is drawn. Feature points are expected from the expectation values which the expectation value map holds, and reduced images are superposed one on the other. The feature points of the original images corresponding to the feature points between which the correspondence is derived from the reduced images are extracted, and the original images are superposed one on the other using the extracted feature points.

  • Patent number: 8340464
    Abstract: In a device for combining a plurality of images having a same photograph range, a position shift between the images having the same photograph range is detected, and the position shift of the images is corrected, and after the position shift is corrected, similarity of the respective portions between the images is evaluated, and the image combining method is changed according to the similarity evaluation. Therefore it is possible to create an image having no position shift due to the shaking of a camera and object blurring due to the movement of the object. Moreover, whether the images are combined or not is determined according to the similarity, hence the processing load is reduced and an image having no object blurring can be created.

  • Patent number: 7221626
    Abstract: A magneto-optical head including a transparent substrate, a coil formed on a first surface of the transparent substrate, a pair of first electrodes formed on a side surface of the transparent substrate so as to be connected to a first end and a second end of the coil, respectively, and an objective lens unit bonded to a second surface of the transparent substrate. The magneto-optical head further includes a flexible printed circuit sheet bonded to the second surface of the transparent substrate, the flexible printed circuit sheet having an opening for insertion of the objective lens unit, a pair of conductor patterns, and a pair of second electrodes respectively formed at first ends of the conductor patterns. The magneto-optical head further includes a pair of conductive wires for connecting the first electrodes and the second electrodes, respectively.

  • Publication number: 20050063254
    Abstract: An assembling device for a magneto-optical head including a glass plate having a first surface and a second surface parallel to each other with a coil formed on the first surface, and a semispherical lens bonded to the second surface of the glass plate. The assembling device includes an XY stage movable in an X-axis direction and a Y-axis direction orthogonal to each other, a jig mounted on the XY stage, a grip mechanism for gripping the semispherical lens, and an XYZ stage for carrying the grip mechanism so that the grip mechanism is movable in the X-axis direction, the Y-axis direction, and a Z-axis direction orthogonal to each other.
