  • Patent number: 10164741
    Abstract: [Problem] To prevent either of two packet data having the same content from being affected by noise [Solution] A packet data transmission device (not shown) transmits first packet data 1A, . . . and second packet data 1B, . . . having the same content intermittently with an idle time I therebetween. When the length of the first and second packet data 1A, . . . , 1B, . . . is denoted by LP, the length of the idle time I is denoted by LI, the duration of low-frequency noise N is denoted by LN, the time with no low-frequency noise from the occurrence of one low-frequency noise N to the occurrence of the next low-frequency noise N is denoted by LC, the following expressions (1), (2) are satisfied. Consequently, either the first packet data or the second packet data is transmitted to a receiver without being affected by noise.

  • Patent number: 10111582
    Abstract: An image processing device comprises an enhancement processing unit that enhances a speckle pattern in an ocular fundus tomographic image. A region-of-interest setting unit sets a desired region in the ocular fundus tomographic image with the enhanced speckle pattern as a region-of-interest, and a feature value extracting unit extracts a feature value of the speckle pattern in the region-of-interest. A disease determining unit makes disease determination for an ocular fundus on the basis of the feature value, and a mapping unit maps, in the ocular fundus tomographic image, a site of the ocular fundus that is determined to have a disease.

  • Patent number: 9989351
    Abstract: The tomographic image capturing device of the present invention comprises a display means (18) configured to: split light from a light source (11) into measurement light and reference light and cause the measurement light and the reference light to be incident to an object (E) and a reference object (49), respectively; capture tomographic images of the object (E) on the basis of interference light generated by superposition of the measurement light reflected from the object (E) and the reference light reflected from the reference object (49); and display tomographic pictures of the object generated on the basis of the captured tomographic images. The tomographic image capturing device has a first image capturing mode and a second image capturing mode. The first image capturing mode is a mode in which the measurement light is two-dimensionally scanned by raster scan to be incident to the object (E) and the tomographic images of the object (E) are captured.

  • Publication number: 20180064334
    Abstract: [Problem] To allow imaging light to be appropriately received by a second camera in the case where a first imaging mode (color imaging mode) is changed to a second imaging mode (autofluorescence imaging mode). [Solution] In the first imaging mode, using a dichroic mirror 30 allows light LB to be received by both a first camera C1 and a second camera C2. In the second imaging mode, using a transparent glass 31 allows light LB to be received by the second camera C2. With this configuration, both in the first imaging mode and in the second imaging mode, light LB from an ocular fundus is appropriately received by the second camera C2 whereby an appropriate ocular fundus image can be taken.
