Abstract
A head-up display for a vehicle includes a picture generating unit arranged to project an image onto a screen and a replicator arranged to receive the image and replicate the image. The head-up display also includes a corrective device located in the optical path of the replicated image downstream from the replicator, arranged to compensate for a complex curvature of an optical combiner downstream from the corrective device and to form a virtual image of the image that is visible from a plurality of viewing positions of a viewing window. The corrective device is arranged to introduce a first disparity offset to at least some of the plurality of virtual image points. The first disparity offset of each virtual image point is substantially constant for the plurality of viewing positions of the viewing window and is a function of the position of the virtual image point in the virtual image.
