Claim 0:
1. An imaging system comprising:
a first camera and a second camera that are to be employed to capture images of a real-world environment from a perspective of a first eye and a second eye of a user, respectively, each of the first camera and the second camera having an adjustable optical focus;
depth-mapping means;
gaze-tracking means; and
a processor configured to:
process depth-mapping data, collected by the depth-mapping means, to generate a depth map of a given real-world scene of the real-world environment;
process gaze-tracking data, collected by the gaze-tracking means, to determine gaze directions of the first eye and the second eye;
identify, based on the gaze directions of the first eye and the second eye, a line of sight of the user and a conical region of interest in the given real-world scene whose axis is the line of sight of the user;
determine, based on the depth map of the given real-world scene, optical depths of a first object and a second object that are present at least partially in the conical region of interest in the given real-world scene, the first object and the second object being at different optical depths;
determine one of the first camera and the second camera that has lesser occlusion in the given real-world scene than another of the first camera and the second camera;
adjust the optical focus of the one of the first camera and the second camera to focus on one of the first object and the second object whose optical depth is greater than the optical depth of another of the first object and the second object, and adjust the optical focus of the another of the first camera and the second camera to focus on the another of the first object and the second object, based on the optical depths of the first object and the second object; and
control the first camera and the second camera to capture at least one first image and at least one second image using the adjusted optical focus of the first camera and the adjusted optical focus of the second camera, respectively.
