Abstract
To overcome the problem met with a video recorder for a conventional HUD camera, in which the HUD camera records the view received via the pilot's combiner and in which the symbols can appear too faint to discern in some conditions, separate sensors A and B are provided for the HUD and for the exterior view, and the outputs are electronically combined to produce a combined video signal for recording.
