Vehicle display device
First Claim
1. A vehicle display device, comprising:
- a viewpoint position acquisition unit that acquires a position of a viewpoint of a user sitting in a driver seat of a vehicle;
a forward information acquisition unit that acquires forward information that is information on a forward direction of the vehicle;
an image generation unit that generates an image reflecting the forward information included in a predetermined area of the forward information acquired by the forward information acquisition unit;
an image display unit having a display surface capable of displaying the image generated by the image generation unit, anda projection unit that projects the image toward a translucent member of the vehicle so that the user sitting in the driver seat is allowed to visually recognize a virtual image, the translucent member reflecting the image displayed on the display surface toward the user,wherein the image generation unit adjusts a position and a size of a first image element among the image elements included in the generated image on the display surface in accordance with movement of the viewpoint position of the user in a vertical direction, the viewpoint position in the vertical direction being acquired by the viewpoint position acquisition unit,when the viewpoint position of the user acquired by the viewpoint position acquisition unit moves upward in the vertical direction, the image generation unit adjusts the position of the first image element on the display surface so that the virtual image to be generated based partially on the first image element moves upward in the vertical direction proportionally with upward movement of the viewpoint position, and adjusts a size of the first image element so that the virtual image is enlarged in the vertical direction proportionally with the upward movement of the viewpoint position, andwhen the viewpoint position of the user acquired by the viewpoint position acquisition unit moves downward in the vertical direction, the image generation unit adjusts the position of the first image element on the display surface so that the virtual image to be generated based partially on the first image element moves downward in the vertical direction proportionally with downward movement of the viewpoint position, and adjusts the size of the first image element so that the virtual image is reduced in the vertical direction proportionally with the downward movement of the viewpoint position.

Abstract
A vehicle display device includes: a viewpoint position acquisition unit acquiring a user viewpoint position of a user seated in a driver seat of a vehicle; a forward information acquisition unit acquiring forward information of the vehicle; an image generation unit generating an image obtained by reflecting the forward information included within a prescribed area among the forward information acquired by the forward information acquisition unit; an image display unit having a display surface capable of displaying the image generated; and a projection unit projecting the image toward a vehicle'"'"'s translucent member such that a virtual image is visible to the user. The image generation unit determines the position and the size of a first image element to be displayed, among image elements included in the generated image, on the display surface, according to the user viewpoint position in the vertical direction acquired by the viewpoint position acquisition unit.
