Abstract
A system comprises an endoscope with a wide-angle lens and a camera. An image of a field of view is captured by the endoscope and a portion of the image is displayed on the display. A popup image is generated and displayed upon image analysis identification of an occurrence of bleeding or motion of edges of an incision that is within the field of view, but outside the portion of the field of view displayed on the display.
Core Innovation
The invention relates to a digitally maneuverable endoscopic imaging system that alters an endoscope image field of view using executable software rather than physically maneuvering the endoscope or the wide-angle lens. The system includes at least one endoscope with at least one wide-angle lens, a camera configured to image a field of view by means of the wide-angle lens, and a display for presenting a selected portion of the field of view.
Executable software selects at least a portion of the field of view and displays the selected portion without physically maneuvering the endoscope or the wide-angle lens. When activated, the executable software provides a popup image upon image analysis identification of bleeding or motion of edges of an incision within the field of view but outside the displayed portion, and the popup image comprises at least one overlay on the displayed portion.
The overlay includes an image of an area of the occurrence and is positioned to indicate a location of the bleeding or motion relative to the portion of the field of view displayed on the display. The partial content also describes distortion correction, digital movement of the display portion for automatic control goals such as center and a predetermined horizon, illumination control, and combining a plurality of images for unitary two-dimensional, unitary three-dimensional, or stereoscopic display formats.
Claims Coverage
The partial content includes one independent claim, with dependent claims further defining digital selection of a field-of-view portion, image distortion removal, digital image movement objectives, illumination control, and combining a plurality of images for specified display types. The main inventive features focus on software-based field-of-view alteration without physical maneuvering and popup overlay warnings tied to image analysis of bleeding or incision-edge motion outside the displayed region.
Software selects and displays a portion of the field of view without physically maneuvering
Executable software is configured to select at least a portion of said field of view without physically maneuvering said endoscope or said wide-angle lens and to display said portion of the field of view on the display.
Popup image with overlay indicates bleeding or incision-edge motion relative to displayed portion
When activated, said executable software is configured, upon image analysis identification of an occurrence of bleeding or motion of edges of an incision within the field of view but outside the portion of said field of view, to provide a popup image, comprising at least one overlay on the portion of the field of view displayed on the display, wherein said overlay comprises an image of an area of said occurrence and is positioned to indicate a location of the bleeding or motion relative to the portion of the field of view displayed.
Distortion removal for the selected field of view portion
Executable software is configured to automatically select a portion of a field of view, remove distortion from that field of view, and display the selected portion on a display.
Digital movement to keep a predetermined object centered
Executable software is configured to automatically digitally move an image to keep a predetermined object centered within a selected portion of the field of view.
Digital movement while maintaining a predetermined horizon
Executable software is configured to automatically digitally move an image to display a selected portion of a field of view while maintaining a predetermined horizon.
Illumination control for a displayed field of view
Illumination-controlling executable software is configured to control at least one aspect of illumination for a displayed field of view.
Combining a plurality of images for specified display types
Executable software is configured to combine a plurality of images into a display image selected from a group consisting of a unitary two-dimensional display, a unitary three-dimensional display, a stereoscopic display, or any combination thereof.
Across the independent and dependent claims, the coverage centers on software-based field-of-view selection and display without physical maneuvering, combined with popup image overlays that indicate locations of bleeding or incision-edge motion occurring outside the displayed portion. Further coverage specifies distortion removal, digital movement objectives, illumination control, and combining a plurality of images into 2D, 3D, and stereoscopic display formats.
Stated Advantages
Provides a popup overlay positioned to indicate the location of bleeding or motion of incision edges relative to the displayed portion of the field of view.
Avoids physically maneuvering the endoscope or the wide-angle lens when altering the field of view by selecting and displaying a portion of the field of view using executable software.
Supports digitally maintaining visual conditions via automatic goals such as a predetermined horizon and maintaining a predetermined object centered within the displayed portion.
Allows removal of distortion from the selected field of view portion before display.
Supports controlling illumination for a displayed field of view.
Supports display of combined images in unitary two-dimensional, unitary three-dimensional, stereoscopic, or combinations of these formats.
Documented Applications
Providing popup warnings or overlays when bleeding or motion of edges of an incision is identified outside the displayed portion, with the popup overlay positioned relative to the displayed portion of the field of view.
Displaying selected portions of a wide-angle lens field of view via digital positioning or zoom with optional distortion removal and optional automatic control goals such as center and predetermined horizon.
Using controllable illumination parameters for a displayed field of view.
Displaying combined images from a plurality of images in 2D, 3D, or stereoscopic display formats as described in the document’s multi-image display options.
