Automated panning in robotic surgical systems based on tool tracking
First Claim
1. A digital zoom and panning system, the system comprising:
- an endoscopic camera device to capture digital video images of a surgical site;
an image buffer coupled to the endoscopic camera device, the image buffer to store one or more frames of the digital video images as source pixels;
a first display device having first pixels to display images;
a first user interface displayed on the first display device to accept a first user input to display a fovea, the first user input including selection of a first source pixel array of source pixels within a first frame of the digital video images with reference to the surgical site and selection of a first target pixel array of target pixels within a subset of the first pixels of the first display device;
a first digital mapping and filtering device coupled between the image buffer and the first display device, the first digital mapping and filtering device to selectively map and filter source pixels in a first region of interest from the image buffer into target pixels in a first destination rectangle for the first display device; and
a tracking system to track a position of at least one object to digitally pan and display the fovea in the first destination rectangle based on one or more tracked positions of the at least one object.

Abstract
In one embodiment, a digital zoom and panning system for digital video is disclosed including an image acquisition device to capture digital video images; an image buffer to store one or more frames of digital video images as source pixels; a display device having first pixels to display images; a user interface to accept user input including a source rectangle to select source pixels within frames of the digital video images, a destination rectangle to select target pixels within the display device to display images, and a region of interest within the digital video images to display in the destination rectangle; and a digital mapping and filtering device to selectively map and filter source pixels in the region of interest from the image buffer into target pixels of the display device in response to the user input.

9. A digital zoom and panning method for digital video, the method comprising:
-
capturing digital video images of a surgical site with an endoscopic camera device; storing one or more frames of the digital video images as source pixels; displaying images on a first display device, the first display device including a first plurality of pixels to display the images; accepting a first user input through a first user interface displayed on the first display device, the first user input to selectively display a fovea on the first display device, the first input including a selection of a first source pixel array of source pixels within frames of the digital video images and a selection of a first target pixel array of target pixels within the first display device to display images; selectively mapping and filtering source pixels in the first source rectangle from the image buffer into the target pixels in the first target pixel array within the first display device; tracking a position of at least one object to determine one or more tracked positions of the at least one object; and digitally panning and displaying the fovea in the first destination rectangle based on the one or more tracked positions of the at least one object. - View Dependent Claims (10, 11, 12, 13)
