Abstract: A device, system and method may enable the obtaining of in vivo images from within body lumens or cavities, such as images the gastrointestinal (GI) tract, where the data such as image data is typically transmitted or otherwise sent to a receiving system in compressed or diluted form. The image may be reconstructed and for example displayed to a user.

Abstract: A color filter array for use in an imaging device including for example red sensitive elements, blue sensitive elements and green sensitive elements, where such blue sensitive elements may occur at a frequency of approximately twice that of said red sensitive elements and said green sensitive elements.

Abstract: Devices, systems and methods for locating an in-vivo signal source. For example, a system for tracking an in-vivo image sensor includes: a location detecting unit to locate the in-vivo image sensor over time; and a data modifying unit to modify data sampled by the location detecting unit based on information sensed by the in-vivo image sensor.

Abstract: A system and method may allow editing of an image stream, which may be produced by, for example, an ingestible capsule. A workstation accepts images acquired by the capsule and displays the images on a monitor as a moving image. The editing method may include, for example, selecting images which follow predetermined criteria. A shortened movie may thus be created.

Abstract: A system and method may detect a transition in an image stream captured within a body lumen. One or more parameters may be computed at points corresponding to a time scale of the image stream. Transition in the values of the parameters may be identified and may indicate a location along the body lumen. The image stream may be segmented at the transition points identified.

Abstract: A system and method for determining the path length through a body lumen, for example to a specified location, is described. A location detection system may identify the location in space of an in-vivo device over time. A path-length detection unit may use data from the location detection system to determine a path traveled by an in-vivo device. A site of interest along that path may be identified. The distance of the site of interest from at least one end point of a body lumen may be determined.

Abstract: A device, system, and method for reducing image data using spatially varying reduction are described. Images may be captured from an in-vivo device, while the reduced images may be transmitted via wireless communications. Reduction may be achieved by selecting a spatial area of interest on an image frame, dividing the spatial area of interest into one or more sub-regions, reducing each sub-region by a defined reduction ratio according to the spatial properties of said sub-region, and transmitting image data from spatial area of interest.

Abstract: A device, system and method may enable the obtaining of in-vivo images or other data from within body lumens or cavities, such as images of the gastrointestinal (GI) tract, where the data obtained at a variable bit rate may be transmitted at a constant bit rate. An in-vivo buffer or storage device may be used to store data prior to transmission.

Abstract: A device, system and method may enable the obtaining of in vivo images from within body lumens or cavities, such as images of the gastrointestinal (GI) tract, where the data such as mosaic image data may be transmitted or otherwise sent to a receiving system in a compressed format.

Abstract: An in-vivo sensing system and a method for creating a summarized graphical presentation of a data stream captured in-vivo. The graphical presentation may be in the form of for example a color bar. The color bar may be a fixed display along side a streaming display of the data stream. A cursor or other indicator may move along the fixed color bar as the data stream is displayed and/or streamed so as to indicate to a health professional what part of the data stream may be currently displayed. The color content in the color bar may map out the data stream and give indication of the location of anatomical sites as well as possible locations of pathology.

Abstract: A system and method may display an image stream, where an original image stream may be divided into two or more subset images streams, each subset image stream being displayed simultaneously or substantially simultaneously. Post processing may be used to fuse images shown simultaneously or substantially simultaneously. The images may be collected from an ingestible capsule traversing the GI tract.
