Abstract: A method of processing images captured using an endoscope comprising a camera is disclosed. According to this method, regular images captured by the camera are received while the endoscope travels through a human gastrointestinal (GI) tract. The regular images are mosaicked to determine any missed or insufficiently imaged area in a section of the human GI tract already travelled by the endoscope. If any missed or insufficiently imaged area is detected, information regarding any missed or insufficiently imaged area is provided. When a target area in the regular images is lack of parallax, the target area is determined as one missed area and an edge corresponding to a structure of the human lumen is highlighted. For a capsule endoscope, the endoscope can be configured to be controlled or steered to move so as to re-image the missed or insufficiently imaged area.

Abstract: A method and apparatus of processing images captured from human gastrointestinal (GI) tract by a capsule camera are disclosed. High frame-rate images captured from human gastrointestinal (GI) tract by a capsule camera are received for processing. The high frame-rate images comprise first images at a first spatial resolution corresponding to a regular frame rate and second images at a second spatial resolution, the first images and the second images are interleaved, and the second spatial resolution is lower than the first spatial resolution. Motion models among the high frame-rate images are derived by applying image registration to the high frame-rate images. The high frame-rate images are stitched according to the motion models to generate stitching outputs comprising stitched images and non-stitched images. The stitching outputs are provided.

Abstract: A capsule endoscopic system is disclosed, where the system comprises a capsule device and a docking device. The capsule device comprises a battery, a secondary coil, and a capsule housing to enclose the battery and the secondary coil in a sealed environment, where the capsule device consists of a first end and a second end in a longitudinal direction of the capsule device, and the battery is located in proximity to the first end and the secondary coil is located in proximity to the second end. The docking device comprises an opening on the docking device, a primary coil to generate an alternating magnetic field, and a primary core. The capsule endoscopic system is arranged so that at least a portion of the secondary coil is enclosed by the primary coil and the battery is outside the primary coil when the capsule device is at the docked position.

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.

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, an object of interest in an image or images is determined. Also, distance information associated with the object of interest with respect to an image sensor of the endoscope is received. The physical area size or physical volume size of the object of interest is then determined based on the image or images, and the distance information.

Abstract: A method and apparatus for capturing an image sequence using a capsule camera are disclosed. According to the present invention, a first energy-based frame time for the special images is determined based on first light energy perceived by the image sensor and a second energy-based frame time for the regular images is determined based on second light energy perceived by the image sensor. The capsule camera captures the image sequence comprising one or more sets of mixed-type images by configuring the capsule camera to cause a mixed-frame distance between the first energy-based frame time for one special image in a target set of mixed-type images and the second energy-based frame time for one regular image in the target set of mixed-type images smaller than an average frame period.

Abstract: 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.

Abstract: Method for leveraging battery residue energy and a capsule endoscope using the method are disclosed. The capsule endoscope is capable of performing one or more functions at a first throughput or a first peak current when the battery has sufficient energy. According to this method, whether the battery energy is sufficient is determined. Upon determining the battery energy being insufficient, at least one function of the one or more functions is performed at a second throughput lower than the first throughput, or at least one function of the one or more functions is switched to another function requiring a second peak current lower than the first peak current
