To provide a head-up display device that is configured to reduce movement of viewpoints of a driver to enable the driver to visually recognize a video comfortably.SOLUTION: A head-up display device 1, which projects a video and displays a virtual image on a front side of a vehicle, comprises a vehicle information acquiring part 10 that acquires vehicle information 4 related to a travelling state of a vehicle 2 and a display distance adjustment mechanism 40 that adjusts a display distance to a virtual image 9 when viewed from a driver 5. In adjusting the display distance, a viewpoint distance by which the driver can best concentrate in each travelling state is memorized, as a recommended value of the display distance in the travelling state, in a memory 23 in advance. Further a current travelling state is determined from the acquired vehicle information through the vehicle information acquiring part 10, and the display distance for the virtual image is adjusted through the display distance adjustment mechanism 40 according to the travelling state by referring to the recommended value memorized in the memory 23.SELECTED DRAWING: Figure 3

    【課題】運転者の視点移動が少なく映像を快適に視認できるヘッドアップディスプレイ装置を提供すること。【解決手段】映像を投射して車両の前方に虚像を表示するヘッドアップディスプレイ装置1は、車両2の走行状態に関する車両情報4を取得する車両情報取得部10と、運転者5から見た虚像9までの表示距離を調整する表示距離調整機構40を備える。表示距離の調整では、予め、各走行状態において運転者が最も集中しやすい視点距離をその走行状態における表示距離の推奨値としてメモリ23に記憶しておく。そして、車両情報取得部10を介して取得した車両情報から現在の走行状態を判断し、メモリ23に記憶された推奨値を参照して、走行状態に応じて表示距離調整機構40を介して虚像の表示距離を調整する。【選択図】図3
