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： A method for transmitting data to a camera without requiring in the camera a conventional wireless transmission capability includes (a) in the camera's field of view, providing an object which forms an image on which the data is encoded; (b) capturing an image of the object using optics of the camera; and (c) recovering the data from the image of the object. The data is encoded by an optically detectable quantity (e.g., light intensity or color) or a pattern in one or more portions of the object. The data can be carried by the distribution of the optically detectable quantity within the image or its derivative. The field of view of the camera may be divided into multiple sub-areas to allow providing multiple data-bearing images. A sequence of such images may be used to increase the amount of data that can be transmitted in this manner.

The field of view of the camera may be divided into multiple sub-areas to allow providing multiple data-bearing images. A sequence of such images may be used to increase the amount of data that can be transmitted in this manner. In addition, the time domain can be used to create one further dimension of data encoding. In addition, communication in the opposite direction may be provided using one or more lighting devices in the camera. One use is to provide a response (e.g., acknowledgement or non-acknowledgement to the data transmission based on the data recovered). The camera's response may be detected by one or more light detectors outside of the camera. Communication can be carried out using an interactive communication protocol. By providing multiple lighting devices in the camera and multiple light detectors in the outside, the system provides a parallel data bus, which may include a clock signal to govern timing on the bus. The data may be represented as quantized values.

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 capsule camera with on-board storage to archive the captured images in on-board non-volatile memory is disclosed. The capsule camera with on-board storage comprises multiple chips including a system processing chip and one or more non-volatile memory chips, where the system processing chip includes a compression module to compress images captured. If the multiple chips use individual chip packages and are disposed on respective printed circuit boards according to a conventional approach, it would require too much space to fit the multiple chips into the capsule camera housing. Accordingly, a capsule camera embodying the present invention is disclosed where the capsule camera integrates an image sensor, a light source, at least one system processing chip comprising compression module, one or more non-volatile memory chips and a battery into a housing, wherein the at least one system processing chip and said one or more non-volatile memory chips are disposed vertically in a multiple chip assembly.
