Problems solved by technology

Neither the CCD nor the optics can be placed in the mid-plane of the tip of the circular endoscope, so these configurations require either very small optics (and small interpupillary distance) or a very small CCD, which limits image quality because The area is small, thus limiting the number of pixels and / or pixel size

[0193] In yet another aspect, coated first surface 631R (631L) of prism assembly 630R (630L) is configured to reflect a first color component in light received by prism assembly 630R from lens assembly 601R (601L) and is configured For transmission of other color components in the received light. In this regard, image capture sensors 610R (610L) and 615R (615L) are not each color sensors with Bayer color filter arrays.

[0194] In contrast, image capture sensor 610R ( 610L ) is a monochrome sensor, eg, a color sensor with the color filter array removed. For purposes of illustration, light received by sensor assembly 620R ( 620L ) is considered to have multiple visible color components—a first visible color component, a second visible color component, and a third visible color component. Image capture sensor 615R (615L) is a color sensor with a color filter array for two of the three visible color components, eg, the number of visible color components in a plurality of visible...

In some aspects, the first and second image capture sensors can comprise different regions of an image capture sensor chip. In some aspects, the apparatus can include an endoscope that includes a distal end that includes the first and second image capture sensors, the beam splitter, and the reflective unit. In some aspects, the apparatus may furt...

Abstract

In a minimally invasive surgical system (200), an image capture unit (325R) includes a lens assembly (304R) and a sensor assembly (320R). The sensor assembly (320R) includes a prism assembly (330R) and coplanar image capture sensors (310R, 315R). Each of the coplanar image capture sensors has a common front end optical structure, eg, lens assembly (304R). A controller (260) enhances images captured by these coplanar image capture sensors. Enhanced images may include (a) visible images with enhanced feature definition; (b) images with increased apparent image resolution; (c) images with increased dynamic range; an image displayed as a pixel color component vector of one or more color components; and (e) an image with an extended depth of field.

Description

technical field [0001] Aspects of the invention relate generally to endoscopic imaging and more specifically to capturing light from a common front end optical structure in multiple image capture sensors. Background technique [0002] The da Vinci Surgical System (da Vinci) commercialized by Intuitive Surgical, Inc., Sunnyvale, California Surgical System) is a minimally invasive telesurgery system that offers patients benefits such as reduced trauma to the body, faster recovery, and shorter hospital stays. A key component of da Vinci Surgical Systems (eg, model IS3000, da Vinci Si HD) is the ability to provide dual channel (ie, left and right) video capture and display of visible images to provide stereoscopic viewing to the surgeon. Such electronic stereoscopic imaging systems can output high-definition video images to the surgeon and can allow features such as image zoom to provide a "zoomed-in" view, which allows the surgeon to identify specific tissue types and propert...
