摘要： A capsule endoscopic system is disclosed for receiving data from a capsule device and providing inductive power to the capsule device wirelessly, where the capsule endoscopic system incorporates a feature to automatically protect the capsule device and the docking device from damage if the capsule device is docked in a backward orientation. In one embodiment, the docking device comprises a current sense circuit to detect the current flowing through the primary coil or primary drive circuit. The occurrence of wrong orientation can be detected from the current. A detection/control circuit can be used to provide the needed control in order to prevent damage to the system. In another embodiment, a resonant circuit comprising a capacitor and the primary coil is used to provide the needed protection when the capsule device is docked with a wrong orientation.

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 capsule camera includes a wireless transmitter that transmits data and a receiving system having multiple receiving units to allowing storing multiple data streams simultaneously. The multiple stored data streams may be used at a later time to derive the best data stream for analysis, based on the network conditions at the time each data packet is received. The best data stream may be derived from the multiple stored data streams at a later time during the decoding process. For example, in a capsule camera application, the multiple data streams may be stored in the memory devices associated with the receiving units, which are typically attached to different locations on the body during diagnosis. The multiple data streams are maintained as the capsule passes through the gastrointestinal tract. Subsequently, after the diagnosis, the receiving units are recovered and connected to a computer or another standalone device for analysis. At that time, the best data stream is derived from the stored data streams using a decoding process, or by comparing the decoded results. Not all receiving units store the data streams at the same time. A screening process, for example, may be provided such that only the receiving units with better network conditions store the data streams. In a real-time system, the data streams may be stored for only a short duration before the best data stream is derived by a decoding process, or by comparing the decoded results.

摘要： Systems and methods are provided for identifying dark areas in images captured by encapsulated cameras or endoscopes and enhancing the visibility of the dark area using intensity stretch. For capsule or endoscope images, there are often some dark areas caused by inadequate lighting. The poor visibility of detailed features in the dark area may reduce the detection rate of anomaly. The present invention calls for a method to detect the dark area based on contour. The intensities inside and outside the dark area are evaluated and are used to generate intensity transformation to stretch intensity in the dark area while minimizing the impact on the image quality outside the dark area.

摘要： Systems and methods are provided for capture control of video data from a capsule camera system having an on-board storage or wireless transmission. The capsule camera system moves through the GI tract under the action of peristalsis and records images of the intestinal walls. For some periods of time, the capsule camera system may move very slowly and there are little differences in the image data between different frames. These frames can be designated for discard to conserve storage space or conserve power. A capsule control processing unit is incorporated to evaluate motion metric based on image data associated with a current frame and a previous frame. A decision is made based on a profile of the motion metric to select an operation mode from a group comprising Capture Mode and Conservation Mode. The capsule camera system is then operated according to the selected operation mode.

摘要： Systems and methods are provided for displaying images captured from a capsule camera system. In order to increase the efficiency of viewing the image sequence, the image sequence is divided into multiple sub-sequences and the multiple sub-sequences are displayed in multiple viewing windows on a display screen concurrently. For images from a panoramic capsule system, the images typically have a very wide aspect ratio and may require different configuration for displaying in multiple viewing windows than that for image sequence having non-wide aspect ratio. The present invention also discloses methods and systems that divide a sequence from panoramic capsule camera into multiple member sequences and form an aggregated video. The aggregated video not only makes viewing more comfortable, but also speeds up viewing time.
