摘要： A method and system for determining a travelled distance by a capsule camera are disclosed. A current global motion vector for a current image in the image sequence is determined, where the current global motion vector corresponds to movement made by the capsule camera between the current image and a reference image associated with the image sequence. A travelled distance by the capsule camera in the GI tract is determined according to the current global motion vector and prior global motion vectors derived for prior images between an initial image and the current image, where the travelled distance is measured from an initial location associated with the initial image to a current location associated with the current image. A method and system for displaying an image sequence captured by a capsule camera are also disclosed. The travelled distances associated with the image sequence are displayed on a display.

摘要： 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.

摘要： 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.

摘要： A capsule device with an inductive powering apparatus is disclosed. The capsule device comprises a secondary coil to generate an induced secondary voltage when a first alternating magnetic field is coupled to the secondary coil externally. Embodiments of the present invention utilize a power conversion device to convert the induced secondary voltage into a DC output voltage for the capsule device. In particular, the power conversion device comprises a voltage booster to generate the DC voltage from a lower induced secondary voltage. Accordingly, the system can be operated using a lower secondary voltage, which will reduce the influence of magnetic flux on the circuit boards inside the capsule.

摘要： A method and apparatus for processing gastrointestinal (GI) images are disclosed. According to this method, a regular image is received, where the regular image is captured using an imaging apparatus by projecting non-structured light onto a body lumen when the imaging apparatus is in the body lumen. One or more structured-light images captured using the imaging apparatus by projecting the body lumen with structured light are received. A target distance for a target region in the regular image is derived based on said one or more structured-light images. A filter is determined based on the target distance and camera parameters associated with the imaging apparatus. A first processed target region is generated by applying the filter to the target region to improve sharpness of the target region. A first processed regular image comprising the first processed target region is provided.
