The invention relates to an image-generation device () for a head-up display (), comprising: a light source, a light modulator suitable for spatially modulating the light emitted by the light source, and a computer () suitable for controlling the light of source and the light modulator such that they generate an image. According to the invention, the light source is composed of a plurality of separate light elements, and the computer is able to modulate the light intensity emitted by each light element independently of the light intensity emitted by the other light elements.

Image-generation device for a head-up display and method for controlling such a device

A compact head-up display for a vehicle includes: an image generator that displays an image on a display surface, and a semi-reflecting optical element, arranged at a distance from the image generator, that forms, on a first side of the optical element, a virtual image. The virtual image is visible from a viewing window on a second side of the optical element. The display includes an optical component that lengthens the optical path of the image passing from the image generator to the optical element. The optical component includes one entry face and one exit face, and a first reflecting face and a second reflecting face. The first reflecting face reflects the image from the entry face toward the second reflecting face. The second reflecting face reflects the image from the first reflecting face toward the exit face. The entry face is in contact with the display surface.
