To provide an image display device that an observer can see easily and by which an observer can recognize the situation of the rate of a mobile body.SOLUTION: A virtual display device displays a vehicle rate image Vs showing the rate of a mobile body as a virtual image to an observer, and can change a perceptive distance D of the vehicle rate image Vs. The processor acquires information showing the rate of the mobile body, (1) extends the perceptive distance D of the vehicle rate image Vs as the rate increases, and (2) performs first vehicle rate image changing processing of keeping a vertical angle of view θVA of the vehicle rate image Vs seen by an observer and a vertical angle of arrangement θDA between the bisector of the vertical angle of view θVA and the horizontal direction, constant.SELECTED DRAWING: Figure 3
【課題】移動体の速度の状況を認識させつつ、観察者にとって見やすい画像表示装置を提供する。【解決手段】虚像表示装置は、移動体の速度を示す車速画像Vsを虚像として観察者に表示し、車速画像Vsの知覚距離Dを変更可能であり、プロセッサは、移動体の速度を示す情報を取得し、(1)速度が速くなるに従い、車速画像Vsの知覚距離Dを延長し、(2)観察者から見た車速画像Vsの縦画角θVA、及び縦画角θVAの二等分線と水平方向との間の縦配置角θDAを一定に維持する、第1の車速画像変動処理を実行する。【選択図】図3
