  • Publication number: 20100168517
    Abstract: An endoscope and method for determining a position of an endoscope body within the human body are disclosed. The endoscope (100) includes at least one first electrode (200) provided in an endoscope body and adapted to generate and transmit an electric signal, at least one second electrode adapted to receive the electric signal transmitted from the first electrode (200), a database for storing electric potential values depending on positions of the endoscope body, and a controller for determining the position of the endoscope body by comparing the electric signal with the electric potential values. The endoscope can recognize the position of the endoscope within the internal organs of the human body with the use of the electric signal induction arrangement and thus, can recognize accurate positions of illness symptoms of the internal organs.

  • Publication number: 20090304093
    Abstract: A transmitting apparatus, a communication system, and a communication method, using a medium, are disclosed. The transmitting apparatus includes an information processing unit for acquiring information about the medium and converting the information into an electric signal, a transmitting electrode for receiving the electric signal and transmitting the electric signal to a receiving electrode provided at the exterior of the medium, and an insulating member for forming a capacitor with the transmitting electrode and the medium, wherein the transmitting electrode transmits the electric signal to the receiving electrode through an electric field generated by the insulating member. Therefore, the electric signal can be safely transmitted through a human body using the electric field.

  • Publication number: 20090086018
    Abstract: The present invention relates to a method for processing an image in a capsule endoscope and capsule endoscope system that processes an internal human body image acquired by a capsule type endoscope swallowable into a human body. The present invention includes a step (a) of acquiring a light emitting image consecutively in a light emitting mode, a step (b) of acquiring a no-light image in a no-light mode after elapse of a prescribed time, and a step (c) of correcting the light emitting image acquired in the step (a) using the no-light image acquired in the step (b). According to the present invention, noises attributed to dark-current and heat occurring in an image of taking an internal human body can be corrected and a quality of an internal human body image can be enhanced using an effective part of a no-light image only in removing dark-current noise and thermal noise.
