  • Patent number: 11051690
    Abstract: An ophthalmological image processing apparatus includes an image obtaining portion for obtaining ophthalmological image data, which is captured by an imaging unit, of a subject eye, and an image processing portion for processing the ophthalmological image data. The image processing portion uses a first front image of the subject eye in a first depth region to correct a second front image of the subject eye captured in a second depth region which is different from the first depth region. The first front image and the second front image are constructed based on the ophthalmological image data. The ophthalmological image processing apparatus can reduce an artifact which is generated in an ophthalmological image.

  • Patent number: 11019993
    Abstract: An OCT data processing device includes a processor that performs acquiring three-dimensional OCT data. The three-dimensional OCT data is OCT data of a tissue of a subject's eye acquired by an OCT device and is obtained by irradiating measurement light on a two-dimensional measurement region. The two-dimensional measurement region extends in a direction intersecting an optical axis of the measurement light. The processor further preforms setting a line pattern, from among a plurality of types of line pattern, with respect to the two-dimensional measurement region for which the three-dimensional OCT data is obtained, at least one of an arrangement, a number, or a shape of one or more lines being different for the plurality of types of line pattern, and extracting, from the three-dimensional OCT data, a two-dimensional tomographic image of a cross section intersecting each of the one or more lines of the set line pattern.

  • Patent number: 9299625
    Abstract: An electronic component can package structure with a can case having an elliptically-shaped cavity in a state before it is fitted with a supporting base portion of a stem. The supporting base portion of the stem has a circular shape. The cavity of the can case is fitted with the supporting base portion of the stem with elastic deformation of the can case. The long diameter of the cavity has an allowance relative to the outer diameter of the supporting base portion of the stem and a gap for the allowance acts as a contraction margin. The short diameter of the cavity is smaller than the outer diameter of the supporting base portion of the stem, so that the supporting base portion is held between the short diameter portions.
