A client-server arrangement for camera viewing using digital cameras across a computer network. A camera server controls a motorized gimbal which determines the viewing angle of a camera, according to signals from a client computer which is equipped with an eye movement tracking system. Movements of the viewer's eyes result in changes in viewing angle of the remote cameras. The original full-resolution image is divided into a foveal area and a peripheral area. Subsequently, if a change in the peripheral area of a field of view is detected relative to the most recently displayed image, the viewing angle of the cameras is changed to center on the detected change, and an image is captured of this anticipated future field of view. When the viewer eventually changes his or her point of interest to the area of detected change, the pre-captured image is transmitted immediately for viewing.
