Abstract
Robotic, telerobotic, and/or telesurgical devices, systems, and methods take advantage of robotic structures and data to calculate changes in the focus of an image capture device in response to movement of the image capture device, a robotic end effector, or the like. As the size of an image of an object shown in the display device varies with changes in a separation distance between that object and the image capture device used to capture the image, a scale factor between a movement command input may be changed in response to moving an input device or a corresponding master/slave robotic movement command of the system. This may enhance the perceived correlation between the input commands and the robotic movements as they appear in the image presented to the system operator.
