Method of image correction for an image projector high head, and device implementing the METHOD

This invention relates to an image correction method for head-up display. It also relates to a device implementing such a procede.Selon the invention, the correction method is basically to produce a corrected image prior to its projection towards the windscreen (2) of the vehicle (1) by a projector (3) high image head so that duplication of failure wherein the windscreen (2) is minimise.Dans one embodiment, the correction processing is to invert a priori the characteristic matrix duplication produced by the windshield. In another embodiment, the correction processing is to produce an adaptively corrected image by minimizing an error function as a threshold predetermine.Application the head-image projectors for motor vehicles.
