Abstract: Systems and methods are provided that enable optical image stabilization and image sensor alignments. By enabling image sensors to be adjusted based on identified misalignments, users of the systems and methods disclosed herein can adjust imaging during the course of a surgery or surgical procedure, without needing to stop the surgery or surgical procedure to manually realign optical components. The optical image stabilization allows for adjustment of sensor components to compensate for shifts or other movement of imaging devices and to maintain focus on a target object. The optical image stabilization also includes digital masks that can be overlaid on an image to block distracting mask shifting.

Abstract: An imaging system includes an imaging scope, a camera, an image processor, and a system controller. The imaging scope is configured to illuminate an object and capture light reflected from the object. The camera has a light sensor with a light-sensitive surface configured to receive the captured light from the imaging scope and generate a digital image representative of the captured light. The image processor is configured to receive the digital image from the camera and use at least one of a random sample consensus (RANSAC) technique and a Hough Transform technique to (i) identify a boundary between an active portion and an inactive portion of the digital image and (ii) generate boundary data indicative of a characteristic of the boundary. The system controller is configured to receive the boundary data from the image processor and use the boundary data to determine a parameter of the imaging system.

The resulting image, or a portion thereof, can then be displayed to the user. A digital panning feature is also provided where the region of interest displayed from the combined field of view including data from the multiple image sensors is changed.

Abstract: Methods are provided using light captured by an endoscope system. Substantially afocal light from the endoscope is manipulated and split. After passing through focusing optics, the already split light again split, this time in image space, producing four portions of light that may be manipulated relative to each other. The four portions of light are focused onto separate areas of two image sensors. The manipulation of the beams can take several forms, each offering distinct advantages over existing systems when individually displayed, analyzed and/or combined by an image processor.

Abstract: A camera head with multiple image sensors that may be detachably connected to an endoscope is presented. Each sensor capturing a portion of the image by the attached endoscope. One sensor receives two portions of the image light at opposing sides of the central image area, and another sensor receives the central image area. The output from the multiple sensors is combined and manipulated into a single higher resolution image which can then be displayed to the user. A virtual horizon rotation feature is also provided which can rotate a displayed image within a combined field of view including data from the multiple image sensors. Various light directing element designs are provided to direct image light to the multiple sensors.

Abstract: The present invention relates to a method for producing adaptive lighting controls for an endoscope with multiple light emitting elements such as distinct light fibers, or distinct distal light emitting diodes (LEDs), etc. The amount of light delivered to the scene can be locally adjusted on a per-light basis to manage the dynamic range of the scene. For example highly reflective metallic tools many benefit from reduced light, while cavities may benefit from increased light projected into the lumen.
