Abstract
(EN)
Provided is a head-up display that can present high quality virtual images while having a small size. This head-up display (100) displays an image as a virtual image (I), the head-up display (100) having a display device (110) that displays an image and a projection optical system (140) that enlarges and projects the image, wherein the projection optical system (140) has a first optical element (123) and a second optical element (125) in order on the optical path from the image, the first optical element (123) has a larger diverging action in the horizontal direction than in the vertical direction, and the second optical element (125) has a larger converging action in the horizontal direction than in the vertical direction.

L'invention concerne un affichage tête haute qui peut présenter des images virtuelles de haute qualité tout en ayant une petite taille. L'affichage tête haute (100) de l'invention affiche une image sous la forme d'une image virtuelle (I), l'affichage tête haute (100) ayant un dispositif d'affichage (110) qui affiche une image et un système optique de projection (140) qui agrandit et qui projette l'image, le système optique de projection (140) ayant dans l'ordre un premier élément optique (123) et un second élément optique (125) sur le chemin optique partant de l'image, le premier élément optique (123) ayant une action divergente plus grande dans la direction horizontale que dans la direction verticale et le second élément optique (125) ayant une action de convergence plus grande dans la direction horizontale que dans la direction verticale.
