A head-up display (HUD) system for an aircraft is disclosed. The HUD comprises a computer receiving information representative of an aircraft flight path. The HUD also comprises a head-up display unit comprising a projector and a combiner. The combiner receives an image from the projector. An imaging sensor is coupled to the computer. The imaging sensor has a pointing direction and a field of view. A region of special processing is defined within the imaging sensor field of view. A program is running on the computer. The program determines an offset for the region of special processing. The offset is based on the aircraft flight path and the imaging sensor pointing direction. The offset is used in the computer to cause display region of special processing to be moved based on the direction of the aircraft flight path.
