Abstract

Une unité d'affichage (20) d'image ATH pour afficher une image d'affichage (I) règle la position d'affichage de l'image d'affichage (I) en fonction de la position (EP) du globe oculaire du conducteur, détectée par une unité de détection (50) de position de globe oculaire. Par conséquent, même si la position (EP) de globe oculaire change, l'image d'affichage (I) peut se déplacer à une position appropriée. L'unité de détection (50) de position de globe oculaire est disposée de façon à ne pas se chevaucher avec l'axe optique (R) du faisceau lumineux permettant à l'unité d'affichage (20) d'image ATH d'afficher l'image d'affichage (I). Par conséquent, on peut éviter que l'image d'affichage (I) ne soit bloquée par l'unité de détection (50) de position de globe oculaire. En outre, l'unité de détection (50) de position de globe oculaire est installée sur la surface d'un tableau de bord (40). Par conséquent, l'unité de détection (50) de position de globe oculaire peut être disposée au voisinage de l'axe optique (R). Grâce à cela, on réduit l'influence de la parallaxe entre la position de l'unité de détection (50) de position de globe oculaire et l'axe optique (R) sur l'erreur de détection de la position (EP) du globe oculaire. En outre, il devient plus facile de disposer l'unité de détection (50) de position de globe oculaire de façon à ce qu'elle ne se chevauche pas avec l'axe optique (R).
