1. A surgical imaging system comprising:
- a multi-link, multi-joint structure including a plurality of joints that interconnect a plurality of links to provide the multi-link, multi-joint structure with a plurality of degrees of freedom, at least one video camera being disposed on a distal end of the multi-link, multi-joint structure, the at least one video camera configured to capture a three-dimensional (3D), optically magnified image having a resolution of at least 3840×
2160 pixels (4K resolution);
at least one actuator that drives at least one of the plurality of joints;
at least one display having a resolution of at least 3840×
2160 pixels (4K resolution) that displays the 3D, optically magnified, 4K resolution image captured by the video camera; and
circuitry configured to;
control the at least one actuator such that a motion of the multi-link, multi-joint structure enables the video camera to maintain aim at a point, which is away from the video camera by a focal length, during movement of the video camera, andcontrol the video camera to autofocus the 3D, optically magnified, 4K resolution image captured by the video camera aimed at the point.

Abstract
Provided is a surgical imaging apparatus that includes a multi-link, multi joint structure including a plurality of joints that interconnect a plurality of links to provide the multi-link, multi joint structure with a plurality of degrees of freedom, at least one video camera being disposed on a distal end of the multi-link, multi-joint structure; at least one actuator that drives at least one of the plurality of joints; and circuitry that detects a joint force experienced at the at least one of the plurality of joints in response to an applied external force, and controls the at least one actuator based on the joint force so as to position the video camera.
