Patent number: 10932649Abstract: A system may control an illuminator to illuminate a surgical site with non-white light and control a camera to capture light reflected from the surgical site. The camera may separate the captured light into a plurality of color components. The plurality of color components may be captured by the camera as a plurality of sets of pixels of a frame in a video stream, and each set of the plurality of sets of pixels may be in a different color channel of the camera. The system may further control, based on color component characteristics of the light captured by the camera, the illuminator to configure the non-white light such that each color channel of the camera has an about equal response to the light captured by the camera for a subsequently captured frame in the video stream.Type: GrantFiled: November 13, 2019Date of Patent: March 2, 2021Assignee: Intuitive Surgical Operations, Inc.Inventors: Jeffrey DiCarlo, Stephen J.

Patent number: 10506914Abstract: Non-white light from an endoscope (201) of a teleoperated surgical system (200) is used to illuminate a surgical site (203). A camera (220L) captures an image of the surgical site, and the image is displayed on a monitor (251). The non-white light illumination minimizes noise in the images of the surgical site presented on the monitor relative to images captured using white light illumination and displayed on the monitor.Type: GrantFiled: March 17, 2015Date of Patent: December 17, 2019Assignee: Intuitive Surgical Operations, Inc.Inventors: Jeffrey DiCarlo, Tao Zhao, Stephen J.

Patent number: 9992428Abstract: Mixed mode imaging is implemented using a single-chip image capture sensor with a color filter array. The single-chip image capture sensor captures a frame including a first set of pixel data and a second set of pixel data. The first set of pixel data includes a first combined scene, and the second set of pixel data includes a second combined scene. The first combined scene is a first weighted combination of a fluorescence scene component and a visible scene component due to the leakage of a color filter array. The second combined scene includes a second weighted combination of the fluorescence scene component and the visible scene component. Two display scene components are extracted from the captured pixel data in the frame and presented on a display unit.Type: GrantFiled: January 27, 2016Date of Patent: June 5, 2018Assignee: Intuitive Surgical Operations, Inc.Inventors: Wenyi Zhao, Jeffrey DiCarlo, Ian E.

Patent number: 9844313Abstract: In one embodiment of the invention, an apparatus is disclosed including an image sensor, a color filter array, and an image processor. The image sensor has an active area with a matrix of camera pixels. The color filter array is in optical alignment over the matrix of the camera pixels. The color filter array assigns alternating single colors to each camera pixel. The image processor receives the camera pixels and includes a correlation detector to detect spatial correlation of color information between pairs of colors in the pixel data captured by the camera pixels. The correlation detector further controls demosaicing of the camera pixels into full color pixels with improved resolution. The apparatus may further include demosaicing logic to demosaic the camera pixels into the full color pixels with improved resolution in response to the spatial correlation of the color information between pairs of colors.Type: GrantFiled: February 25, 2014Date of Patent: December 19, 2017Assignee: Intuitive Surgical Operations, IncInventors: Jeffrey DiCarlo, David D.

Patent number: 9024535Abstract: An optical lighting apparatus having a constant luminance with a drive current controlled by a controller unit. A temperature controlled photodetector indirectly monitors the luminance and informs the controller when a change in luminance has occurred so that the controller can make appropriate adjustments to the drive current. Also disclosed is a method of regulating the drive current to a light source to enable the luminance to remain fixed and independent of fluctuations in ambient temperature. A temperature compensated photodetector senses the amount of light reflected off a diffuser lens and feeds back the output to a controller circuit which regulates the drive current to the light source. The lighting apparatus has application in calibrating imaging systems, such as digital cameras, and for scanning devices.Type: GrantFiled: October 14, 2009Date of Patent: May 5, 2015Assignee: Hewlett-Packard Development Company, L.P.Inventors: Carl Picciotto, Glen Eric Montgomery, Jeffrey DiCarlo
