  • Patent number: 10638916
    Abstract: In an endoscope device, a control unit brings an imaging device into an operation in a first read-out mode. In the first read-out mode, the imaging device reads out pixel signals from a plurality of pixels in a first time. After an instruction for the measurement of a subject is generated, the control unit brings the imaging device into an operation in a second read-out mode. In the second read-out mode, the imaging device reads out the pixel signals from the plurality of pixels in a second time. The second time is shorter than the first time. The control unit causes an imaging condition switching unit to switch imaging conditions on the basis of an operation of the imaging device in the second read-out mode.

    Abstract: Still image display of a recent video image of tissue as a reference still image prior to a switch in the mode of illumination of the tissue. The still image is displayed concurrently with live video of the tissue under a different mode of illumination, to facilitate discrimination between healthy and diseased tissue. When a practitioner switches a light source from a “first light” to a “second light”, the second light video may be frozen/captured and displayed as a reference still image as a PIP, and the second light live video is displayed concurrently. The second light can be infrared and/or near infrared light. The second light can include structured light to project a structured light pattern to facilitate structure measurements. The second light source is configured with a numerical aperture greater than the first light source.

The image sensor receives at least a portion of the imaging light rearwardly reflected by the axicon mirror. The tilted optical element, situated between the axicon mirror and the interior surface, moves a selected first portion of the imaging light away from being incident on the image sensor, while allowing a second portion of the imaging light to be incident on the image sensor.

  • Patent number: 9872610
    Abstract: A reflected light image and a fluorescent light image of an observed region are acquired with an imaging system. A gradation level of the reflected light image is set on the basis of a feature value of the acquired reflected light image. The focus of the imaging system is controlled in accordance with the set gradation level. The fluorescent light image is corrected using a focus-controlled reflected light image of the observed region. Accordingly, the image of an object in the observed region from which the fluorescent light is generated is sharpened.

  • Patent number: 9820653
    Abstract: An imager for in vivo viewing of diseased tissue by way of fluorescently conjugated molecules. A generally planar imaging surface with a microlens array.

  • Patent number: 9729799
    Abstract: A minimally invasive surgical system includes a scene anti-bloom process that allows switching between imaging modes on a stereoscopic display without causing a surgeon to look-away or being momentarily distracted by sudden changes in overall scene luminance. The process receives a switch from a first imaging mode to a second imaging mode. An overall scene luminance of a scene in the first imaging mode is less than an overall scene luminance of a scene in the second imaging mode. The process delays the switch to the second imaging mode until after an illumination output level of a visible illumination source has changed to a higher output level, and then switches to the second imaging mode.

  • Patent number: 9629527
    Abstract: Broadband light BB and narrowband light NB are simultaneously irradiated to a subject. A blue signal B, a green signal G, and a red signal R are obtained by imaging the subject using a color CCD 33. A base image is generated from the signals B, G, and R of three colors. A B/G image having a B/G ratio is generated. A superficial blood vessel extraction image is obtained by extracting a pixel, in which the B/G ratio is equal to or less than a boundary value Ls between the mucous membrane and the superficial blood vessel, from the B/G image. A medium-deep blood vessel extraction image is obtained by extracting a pixel, in which the B/G ratio is equal to or greater than a boundary value Ld between the mucous membrane and the medium-deep blood vessel. The boundary values Ls and Ld differ depending on each observation mode.

  • Patent number: 9582878
    Abstract: A base image is created from RGB image signals. A B/G ratio between the B image signal and the G image signal is calculated, and a G/R ratio between the G image signal and the R image signal is calculated. A frequency component-enhanced image in which a frequency component corresponding to an abnormal part different from a normal part is enhanced is generated based on the base image. A composition ratio which indicates the ratio for composing the frequency component-enhanced image with the base image is set based on the B/G ratio and the G/R ratio. The frequency component-enhanced image is composed with the base image at the set composition ratio to generate a structure-enhanced image in which the structure of the abnormal part is enhanced.
