摘要： A method for imaging a patient's gastrointestinal tract including upper parts of stomach using a capsule camera system are disclosed. According to the method, the capsule camera is administered to a patient by swallowing the capsule camera through patient's mouth. For each target examination position selected from a set of examination positions: the patient positioning system is adjusted to a target positioner bed position associated with the target examination position with the patient on the positioner be. Adjusting patient positioning system comprises adjusting the positioner bed to tilt at a tilt angle, and wherein the set of examination positions comprises at least two different tilt angles; and the patient positioning system still is held at the target examination position for a pre-defined period of dwelling time to allow the capsule camera to capture stable pictures. Image data captured by the capsule camera are then collected.

摘要： A method and apparatus of processing and displaying images captured using an in vivo capsule camera are disclosed. One or more overlapped areas between a target image and each image in a neighboring image group are determined, which comprises at least two neighboring images around the target image. Marked pixels in the target image are then determined, where a pixel in the target image is designated as a marked pixel if the pixel is within an overlapped area between the target image and at least one neighboring image. If the total number of the marked pixels in the target image exceeds a threshold and the number of the marked pixels associated with the overlapped area(s) between the target image and any image in the neighboring image group is below the threshold, the target image is excluded from a set of images to be displayed on a display device.

摘要： Systems and methods are provided for displaying images captured from a panoramic capsule camera system. The panoramic images typically have a very wide aspect ratio and may cause fatigue when viewed by a diagnostician over an extended period on a display. The images taken by a capsule camera through the GI track may take a couple of hours or more to view at a typical frame rate of 30 frames per second or whatever rate that's deemed appropriate. The present invention 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.

摘要： A camera system uses one or more image sensor IC chips each having multiple pixel arrays on the same semiconductor substrate (i.e., “multiple pixel arrays on a chip”). In one embodiment, such a camera system includes: (a) optical components that create multiple images in close physical proximity of each other (e.g., within a few millimeters or centimeters); and (b) a single sensor substrate (“chip”) containing multiple 2-dimensional pixel arrays that are aligned to capture these multiple images, so as to convert the multiple images into electrical signal. The pixel arrays can be manufactured using a CCD or a CMOS compatible process. For manufacturing reasons, such a chip is typically two centimeters or less on a side. However, large chips can also be made. Optional electronic components for further signal processing of the captured images may be formed either on the sensor chip (i.e., in a “system-on-a-chip” implementation), or in a separate back-end application specific integrated circuit (ASIC). In addition, digital storage components, display elements, and wired or wireless communication links may also be included in any suitable combination to allow review and further processing of the captured images.

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.

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.
