Description

上記目的を達成するため、本発明のある態様は車両表示装置である。この装置は、画像信号に基づいて画像表示光を生成する画像生成部と、前記画像生成部が生成した画像表示光を投射する投射口と、前記投射口から投射された画像表示光を虚像として提示するコンバイナとを備える。前記画像生成部は車両の内部のルームミラーのミラー面側に取り付けられ、前記投射口はそのミラー面と対向する背面よりもミラー面側であって、入射する外来光の少なくとも一部がそのルームミラーによって遮られる位置に設けられる。前記投射口は、前記画像生成部の下部に位置するとともに、その上端は前記ルームミラーの下端よりも前記車両の天井側にあり、前記画像表示光を前記ルームミラーの方向且つ下方に投射する。 In order to achieve the above object, an aspect of the present invention is a vehicle display device. The apparatus includes an image generation unit that generates image display light based on an image signal, a projection port that projects the image display light generated by the image generation unit, and the image display light projected from the projection port as a virtual image. And a combiner to present. The image generation unit is attached to the mirror surface side of a room mirror inside the vehicle, the projection port is on the mirror surface side with respect to the rear surface facing the mirror surface, and at least a part of incident external light is in the room It is provided at a position blocked by the mirror. The projection opening is located at a lower part of the image generation unit, and an upper end thereof is located on a ceiling side of the vehicle with respect to a lower end of the room mirror, and projects the image display light toward and below the room mirror.

Claims

An image generation unit that generates image display light based on the image signal;
A projection port for projecting the image display light generated by the image generation unit;
A combiner that presents the image display light projected from the projection port as a virtual image,
The image generation unit is attached to the mirror surface side of a room mirror inside the vehicle, and is provided at a position where at least a part of incident external light is blocked by the room mirror ,
The projection port is located at a lower part of the image generation unit, and an upper end thereof is on a ceiling side of the vehicle with respect to a lower end of the room mirror, and projects the image display light in a direction and below the room mirror.
A display device for a vehicle.

The image generation unit includes a reflection unit that determines an optical path for projecting the image display light from the projection port,
The reflection part reflects sunlight incident from the room mirror side to an optical path different from the optical path of the image display light incident on the reflection part.
The vehicular display device according to claim 1.
