摘要： A capsule endoscopic device with movement control is disclosed. The capsule endoscopic device comprises a capsule housing, one or more electrodes disposed fixedly through the capsule housing, a signal generation/signal driver unit, an interface circuit and a switch module. The electrodes apply electrical stimulus to living body tissue in a patient's gastrointestinal track. The signal generation/signal driver unit generates the electrical stimulus for the electrodes. The switch module is coupled to the electrodes, the signal generation/signal driver unit and the interface circuit. Furthermore, the switch module is configured to connect the electrodes to the signal generation/signal driver unit or the interface circuit depending on an operation mode. The switch module, the signal generation/signal driver unit and the interface circuit are inside the capsule housing.

摘要： An in vivo endoscope illuminates tissue using multiple sources. Light from a short-range source exits a tubular wall of the endoscope through a first illumination region that overlaps an imaging region, and the light returns through the imaging region after reflection by tissue, to form an image in a camera. Light from a long-range source exits the tubular wall through a second illumination region that does not overlap the imaging region. The endoscope of some embodiments includes a mirror, and light from an emitter for the short-range source is split and reaches the first illumination region from both sides of an optical axis of the camera. Illuminating the first illumination region with split fractions of light results in greater uniformity of illumination, than illuminating directly with an un-split beam. The energy generated by each source is changed depending on distance of the tissue to be imaged.

摘要： A method and device for capturing a mixed structured-light image and regular image using an integrated image sensor are disclosed, where the structured-light image is captured using a shorter frame period than the regular image. In order to achieve a shorter frame period for the structured-light image, the structured-light image may correspond to an image captured with reduced dynamic range, reduced spatial resolution, or a combination of them. The capturing process comprises applying reset signals to a pixel array to reset rows of pixels of the pixel array, reading-out analog signals from the rows of pixels of the pixel array and converting the analog signals from the rows of pixels of the pixel array into digital outputs for the image using one or more analog-to-digital converters.

摘要： A method for presentation of image sequence data is disclosed. The intensity of the image sequence data is used to derive the navigation guide. Each representative data may correspond to an average pixel value, a median pixel value, a minimum value, or a maximum value of the sub-image or said one or more images. Each representative data may also comprise a term proportional to a mathematical product of adjusted color values. The series of representative data can be plotted along with highlighting an area between a curve corresponding to the series of representative data and a coordinate axis by filling the area with a highlight color. Each representative data may comprise a minimum value and a maximum value associated with the sub-image, or one or more images.

摘要： A method characterizes manufacturing imperfections in a camera and variations in its operating environment to allow images captured by the camera to be compensated for these defects. The method includes: (a) illuminating a field of view of the optical elements under a controlled condition; (b) exposing multiple images onto the image sensor under the controlled condition; (c) extracting from the multiple images parameter values for pixels of the image sensor; and (d) compensating images taken subsequently in the camera using the parameter values. The controlled condition includes an external light source for illumination, and the image sensor is sensitive to color components.

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： A method of processing images captured by an in vivo capsule camera is disclosed. The images having large overlap exceeding a threshold are stitched into larger images. If the current image and none of its neighboring images has large overlap, the current image is designated as a non-stitched image. Any image, that exists between two images stitched and is not included in the stitched image, is also designated as a non-stitched image. The large-overlap stitching can be performed on the images iteratively by treating the stitched images and non-stitched image as to be processed images in the next round. A second stage stitching can be applied to stitch small-overlap images. The small-overlap image stitching can also be applied iteratively. A third stage stitching can be further applied to stitch the output images from the second stage processing.
