  • Patent number: 10785428
    Abstract: A method and apparatus for imaging a body lumen are disclosed. According to the method, an imaging apparatus is induced into the body lumen. Structured light from the imaging apparatus is projected into the body lumen. The structured light reflected from anatomical features in the body lumen is detected by the imaging apparatus. A first structured light image is generated from the detected structured light by the imaging apparatus. Non-structured light is emitted from the imaging apparatus into the body lumen. The non-structured light reflected from the anatomical features in the body lumen is detected by the imaging apparatus. A non-structured light image is generated from the detected non-structured light by the imaging apparatus. The frame period of the first structured light image is shorter than the frame period of the non-structured light image. In one embodiment, the imaging apparatus corresponds to a capsule endoscope.

  • Patent number: 10736559
    Abstract: A method and apparatus for estimating or measuring a physical area or physical volume of an object of interest in one or more images captured using an endoscope are disclosed. According to the present method, one or more structured-light images and one or more regular images captured using an imaging apparatus are received. An object of interest in the regular images is determined. Distance information associated with the object of interest with respect to the imaging apparatus is derived from the structured-light images. The physical area size or physical volume size of the object of interest is determined based on the regular images and the distance information. The imaging apparatus can be a capsule endoscope or an insertion endoscope.

  • Patent number: 10742909
    Abstract: A method and device for improving the accuracy of depth information derived from a structured-light image for a regular image are disclosed. In one example, an additional structured-light image is captured before a first structured-light image or after a regular image. The depth information for the regular image can be derived from the first structured-light image and corrected by incorporating depth information from the additional structured-light image. A model for depth information can be used to predict or interpolate depth information for the regular image. In another example, two regular sub-images may be captured with a structured-light image in between. If substantial frame differences or substantial global motion vector/block motion vectors are detected, the two regular sub-images will not be combined in order to avoid possible motion smear. Instead, one of the two sub-images will be selected and scaled as the output regular image.
