ABSTRACT:
A vehicle has an eye level display for displaying information to the driver by means of images projected on to the windshield and reflected off it. The eye level display system includes means for correcting the image projected, in order substantially to eliminate multiple images. The projected image is corrected essentially by producing a corrected image, in the form of a digital matrix, before it is projected on the windshield by the projector. In one embodiment, the corrective processing step comprises inverting the matrix characteristic of the multiplication caused by the windshield. In another embodiment, it consists in producing a corrected image adaptively by minimising an error function below a predetermined threshold.
