摘要
The general technical field of the invention is that of viewing devices mounted on vehicles and comprising a display whose image is reflected by the windscreen of the vehicle, making it possible to superimpose the displayed image on the outside world. One of the major problems with this type of display is that the windscreen gives, by reflection, two non-superimposed doubled images. The basic principle of the invention is that the initial image is such that the combination of the first reflected image and the second image reflected by the windscreen gives a “clean” or “ideal” perceived image without any offsets. To perform this function, an image is generated on the display that comprises, obviously, the “ideal” image, but also a succession of offset images comprising negatives of the “ideal” image so that the resultant sum of the first reflected image and of the second reflected image includes no more than the “ideal” image. Obviously, the principle of the invention can be applied to simple displays or to displays comprising an image collimated to infinity or to a great distance.
