Abstract: An apparatus and method for visualizing a scene in the form of image rays projecting along a path includes a plurality of charge coupled device detectors disposed along the path to receive the image rays and to collect data. This data includes both noise data which is collected at a generally constant rate, and image data which is collected when the image rays are present along the path. A clock which facilitates discharge of the data from the image array has a first state wherein the data is retained in the detectors, and a second state wherein the data is discharged from the detectors. An event detector including a plurality of charge coupled device detectors forms an event array which places the clock in the first state when the image rays are present along the path and places the clock in the second state when the image rays are absent from the path.

Abstract: A micro video imaging camera has a detachable distal module which is replaceable with one of different characteristics (e.g., angled), and sterilizable. Thus a non-replaceable CCD and video transmitter are connected to an inner body which comprises in effect a lens tube. The module comprises an outer body encasing the inner body which has a filter (optional) at its tip and a magnifying lens optically connected to an image conduit optical segment. The inner body receives the image conduit, the output of which is focused by the lens in the inner body on a CCD microprocessor. The model may be replaced with an angular distal end or lenses of different fields of view. Fiber optic light filaments may be used to illuminate the field of view of the tip of the module, either housed internally or externally of the inner body.
