20080310027 | Light Source - An apparatus for coupling radiation of individual laser diode emitters into a common optical fiber is disclosed. The radiation is collimated along fast axis and combined by using crossed pairs of flat mirrors. The combined beams are collimated by a common slow axis collimating lens. The laser diode emitters are disposed on both sides of an optical axis of the slow axis collimating lens such that the optical path lengths from the emitters to the slow axis collimating lens are equal. | 12-18-2008 |
20090074265 | IMAGING REVIEW AND NAVIGATION WORKSTATION SYSTEM - An imaging review system that displays sequences of in-vivo panoramic images stitched together into a single video while providing edit/review/location information of the individual images within the body being imaged. | 03-19-2009 |
20090278921 | Image Stabilization of Video Play Back - Systems and methods are provided for compensating motion fluctuation and luminance in video data from a capsule camera system. The capsule camera system moves through the GI tract under the action of peristalsis and records images of the intestinal walls. The gut itself contracts and expands but exhibits little net movement. The capsule's movement is episodic and jerky. It typically pitches, rolls, and yaws. Its average motion is forward, but it also moves backward and from side to side along the way. Luminance fluctuation and other luminance artifacts also exist in the captured capsule video. Motion and luminance compensation for the capsule video will improve the visual quality of the compensated video. | 11-12-2009 |

20110001789 | IMAGING SYSTEM HAVING A FOLDED OPTICAL AXIS - An optical imaging system having a folded optical axis. | 01-06-2011 |
20110249105 | In Vivo Autonomous Camera with On-Board Data Storage or Digital Wireless Transmission in Regulatory Approved Band - A capsule camera apparatus includes a swallowable housing, a light source within the housing, a camera within the housing for capturing a first digital image and a second digital image of a view of the camera illuminated by the light source, a motion detector that detects a motion of the housing the first digital image and the second digital image, and a motion evaluator that selects a disposition of the second digital image, based on a metric on the motion. The disposition may include writing the second image into an archival storage or providing the second digital image to the outside by a wireless communication link. | 10-13-2011 |
20130020470 | CAMERA SYSTEM WITH MULTIPLE PIXEL ARRAYS ON A CHIP - An integrated circuit for capturing panoramic image is disclosed. The integrated circuit comprises a plurality of pixel arrays fabricated on a common substrate, wherein each pixel array being positioned to capture an image to be projected thereon, and wherein the orientation of each pixel array is rotated to match with the orientation of the image projected thereon. The integrated circuit also includes readout circuits coupled to the pixel arrays for reading electrical signals corresponding to the images captured from the pixel arrays. In one embodiment, the plurality of pixel arrays corresponds to four pixel arrays and the orientation of said each pixel array is substantially 90° apart from a neighboring pixel array. The integrated circuit further comprises a timing and control circuit, wherein the timing and control circuit is for controlling said one or more readout circuits and the plurality of pixel arrays. | 01-24-2013 |
20150163482 | METHODS TO COMPENSATE MANUFACTURING VARIATIONS AND DESIGN IMPERFECTIONS IN A CAPSULE CAMERA - 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. | 06-11-2015 |
