To avoid deterioration in visibility of a virtual image.SOLUTION: An image processing unit applied to a display controller 200 includes a generation section 230 which generates a display image including a display element corresponding to a virtual image visually recognized by a user. A virtual image on a virtual plane S is visually recognized by the user as if the virtual plane S were substantially parallel to a road surface H and the virtual plane S rose from the road surface H by a prescribed height. The generation section 230 determines a planar shape of the display element so as to change the size of the virtual image visually recognized by the user on the basis of a view point height of the user. Concretely, when an object approaches a view point 102 of the user in an own vehicle and the view point height of the user changes to a lower position, the generation section 230 determines the size of the planar shape of the virtual image on the virtual plane S so as to change in a prescribed direction.SELECTED DRAWING: Figure 1

    【課題】虚像の視認性の低下を回避させる。【解決手段】表示コントローラ200に適用される画像処理ユニットは、ユーザによって視認される虚像に対応する表示要素を含む表示画像を生成する生成部230を備える。仮想平面S上の虚像は、仮想平面Sが道路面Hに略平行であり、且つ仮想平面Sが道路面Hよりも所定高さだけ上昇したようにユーザによって視認される。生成部230は、ユーザの視点高さに基づきユーザによって視認される虚像の大きさが変化するように、表示要素の平面形状を決定する。具体的には、物体が自車両内のユーザの視点102に近づき、ユーザの視点高さが低い位置に変化する時に、生成部230は、仮想平面S上の虚像の平面形状の大きさが所定方向に変化するように決定する。【選択図】図1
