Abstract
A system and method for canceling vibrations in a head-up display device displaying a projected image superimposed over a field of view of a driver of a vehicle includes a mounting plate fixed to the vehicle and supporting a combiner panel while allowing the combiner panel to be rotated about a rotation axis. An image source generates a signal corresponding to the projected image, which is then projected upon the combiner panel by a picture generating unit. A rotation sensor measures rotation of the combiner panel and causes a displacement compensation controller to shift the projected image to offset displacement caused by vibration which would otherwise cause the projected image to appear to move. In this way, unwanted movement of the projected image caused by vibration is effectively cancelled-out. Alternative arrangements of components of the system are disclosed. A method for vibration cancellation in a HUD device is also provided.
