  • Publication number: 20190282139
    Abstract: Provided are an in-blood component measurement method, an in-blood component measurement device, and an in-blood component measurement program, enabling more accurate measurement of a proportion of glycohemoglobin in the total hemoglobin concentration in blood. The in-blood component measurement method is designed to have a constitution including the steps of irradiating, with near-infrared light, blood that is a target to be measured for a proportion of glycohemoglobin in the total hemoglobin concentration in blood, receiving transmitted light of the near-infrared light passing through the blood, measuring an absorption spectrum of the blood on the basis of the transmitted light received, and calculating the proportion for the blood that is the target of measurement by comparing absorbance at a first wavelength range including 1450 nm in the measured absorption spectrum to absorbance at the first wavelength range in the absorption spectrum of blood in which the proportion is already known.

  • Patent number: 10413170
    Abstract: Through the present invention, a perimetry result is obtained for a position on a retina surface designated as a position to be tested. As illustrated in the drawing, “the position of a ganglion cell (RGC)” and “the position of a photoreceptor cell (C) for sending information to the ganglion cell (RGC)” are offset on the retina surface (macular part). Here, when position (P1) is designated as a test position for testing the functioning of a ganglion cell at position (P1), the perimeter of the present invention finds “the position (P2) of the photoreceptor cell for sending information to the ganglion cell at position (P1),” presents a visual target at position (P2) rather than position (P1), and tests a visual field. The information of the visual target is sent to the ganglion cell at position (P1), and the functioning of the ganglion cell can therefore be tested.

  • Patent number: 10285587
    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.

  • Publication number: 20190124293
    Abstract: [Problem] To make a device compact and inexpensive by omitting a frame buffer. [Solution] First packet data PD1 that is sequentially received from a first camera C1 and second packet data PD2 that is sequentially received from a second camera C2 are alternately and sequentially transmitted to an external device 2 before data for one screen is accumulated. Therefore, a frame buffer for saving the data for one screen is not necessary, and a device can be made correspondingly more compact and less expensive.

  • Patent number: 10219692
    Abstract: The tomographic image capturing device of the present invention is configured to: split light from a light source (11) into measurement light and reference light; cause the measurement light and the reference light to be incident to an object (E) and a reference object (49), respectively; and 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). The tomographic image capturing device has a first image capturing mode and a second image capturing mode. The first and second image capturing modes are each a mode in which the measurement light is two-dimensionally scanned to be incident to the object (E) and the tomographic images of the object (E) are captured. The two-dimensional scans in the second image capturing mode require a shorter time than that required for the two-dimensional scans in the first image capturing mode.
