Abstract
The invention is directed to systems, methods and computer program products for providing focus control for an image-capturing device. An exemplary method includes capturing an image frame using an image-capturing device and recording video tracking data and gaze tracking data for one or more image frames following the captured image frame and/or for one or more images frames prior to the captured image frame. The exemplary method additionally includes calculating a focus distance and a depth of field based at least partially on the recorded video tracking data and recorded gaze tracking data. The exemplary method additionally includes displaying the captured image frame based on the calculated focus distance and the calculated depth of field.
