ABSTRACT:
In a video imaging and transmission system, the entire field of view of camera equipment aboard a remotely piloted vehicle is imaged as high resolution data. This high resolution data is digitized and stored in memory aboard the remote vehicle. In order to reduce the bandwidth of the information which is to be transmitted to a ground-based operator, only a selected portion of the stored high resolution data, corresponding to the output of oculometer and head position equipment that monitors the operator's look angle at a display, is read out from memory and transmitted as high resolution data. The remaining portion of the image provided on the operator's display is comprised of low resolution data derived from the high resolution data stored in memory. Because the high resolution data is obtained from memory and not from the camera equipment directly, the camera is effectively decoupled from the data link. As such, the system permits the camera to be a single movable sensor or an array of multiple fixed sensors. It also substantially increases the speed of operation of the system.
