Abstract: An improved method and system for capturing and displaying a series of successive video images using at least first and second different exposure times, so that first video images captured using said first exposure time occur alternately in said series with second video images captured using said second exposure time. The method employs a digital computer and a software program for generating and storing digital data representative of said first and second video images, and utilizing that digital data to selectively display (a) side-by-side reproductions of said first and second images or (b) reproductions of only said first or said second video images or (c) composite images derived from the first and second video images digital data.

Abstract: The invention provides for capturing and displaying video images by (1) creating a video signal comprising a succession of video fields or frames containing optical image video data representing the captured optical image, with a plurality of first video fields or frames representing the optical image at a first exposure level and a plurality of second video fields or frames representing the optical image at a second exposure level different from the first exposure level, with the first field or frames being interspersed among said second fields or frames, and (2) utilizing that video signal to (a) generate a video display of the image represented by said first video fields or frames or the image represented by said second video fields or frames, or (b) concurrently generate a first video display of the image represented by said first video fields or frames and a second video display of the image represented by said second video fields or frames.

Abstract: A method and apparatus are provided for correcting for optical misalignment of the dual (left and right) images produced by a stereo electronic endoscope, or of the corresponding dual images produced by coupling electronic imaging devices to each of two monocular teaching ports of a stereo optical endoscope. The stereo image alignment technique comprises electronically capturing the video image data of the dual images, and subsequently processing that data electronically to correct for optical alignment errors. The method involves digitizing the electronic data and digitally performing the equivalent of vertical image shift, and/or image size change, and/or image rotation as required to correct for any visual image misalignment.

Abstract: An endoscope is provided that comprises an imaging device such as a micro-size video camera supported by a novel device-steering shaft assembly. The shaft assembly comprises a malleable or rigid shaft, an imaging device carrier releasably and pivotally supporting the imaging device at one end of the shaft, and operating means including a flexible operating cable and cable moving means attached to the opposite end of the shaft for moving said cable and thereby pivoting the imaging device carrier relative to the shaft so as to alter the viewing angle of the supported imaging device. Using a malleable shaft offers the advantage that the shaft is manually reformable into various configurations to facilitate access to different surgical sites, with the shaft having the ability to remain in each selected configuration until manually reformed into another configuration. Alternatively, the imaging device may be permanently attached to the device carrier.

Abstract: An endoscope is provided that comprises a micro-size video camera, a flexible cable attached to the camera comprising fiber optical means for transmitting light to illuminate the site viewed by the camera and electrical conductors for transmitting electronic signals generated by the camera in response to images viewed by the camera, and a malleable or rigid shaft detachably connected to and supporting said camera and said cable. The rigid shaft may be straight or may be preformed in a selected curved configuration. In an alternative embodiment of the invention, a malleable shaft is permanently attached to said camera. Using a malleable shaft offers the advantage that the shaft is manually manipulable into various configurations to facilitate access to different surgical sites, with the shaft having the ability to remain in each selected configuration until manually reformed into another configuration.
