1. A method of head-worn displaying an image in accordance with at least two different projection reference frames, each projection reference frame being chosen in relation to an object inside or outside a carrier, the object being different for each projection reference frame and each object being in movement relative to each other object, the method comprising:
extracting from a single image stream acquired from external systems including image sensors, an image stream for each of the at least two different projection reference frames;
for each of the at least two different projection reference frames, adapting the image stream corresponding to that projection reference frame to a display frame using additional data relating to the corresponding projection reference frame, wherein the at least two different projection reference frames are different than the display frame;
generating a resulting stream comprising the adapted image streams; and
projecting the resulting stream onto a display surface defined by the display frame,
wherein the single image stream is acquired via a common image input, the single image stream being filtered by a filter unit associated with the common image input to distinguish image streams relating to the at least two different projection reference frames.
