  • Patent number: 8529436
    Abstract: An endoscope, an endoscope system having an endoscope, and an endoscope control method are disclosed. The endoscope includes: a main body and a buoyancy control device. The main body may be configured in the form of a capsule and include an image capturing unit for capturing image information. The buoyancy control device may control buoyancy by changing the volume of the main body. Images of various types of internal organs can be precisely captured.

  • Patent number: 8360961
    Abstract: Disclosed is a capsule-type endoscope, including: a lens for obtaining an image inside the body, one or more sensors for obtaining information related to the inside of the body, a controller for interleaving the information detected by the one or more sensors with the image captured by the lens and encoding the image interleaved with the sensor data for signal output, and a transmitter for transmitting a signal from the controller.

  • 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: 20100130818
    Abstract: A capsule-type endoscope is disclosed. Information related to position and movement of the capsule-type endoscope inserted into a body are checked and a frame rate is controlled according to a digestive organ in which the capsule-type endoscope is located based upon the information, so as to capture every digestive organ inside the body by using one capsule-type endoscope. Also, the frame rate can be controlled according to a moving velocity in each digestive organ, thus to reduce unnecessary power consumption, resulting in a decrease of an operation time of the capsule-type endoscope having a limited battery capacity. In addition, an amount of captured images can be reduced by effectively obtaining images according to the moving velocity in each digestive organ and a time taken by a doctor for a medical examination can be shortened.
