PROBLEM TO BE SOLVED: To surely detect a visual recognition object to be visually recognized by drivers, and to cause the driver to surely visually recognize the detected visual recognition object.SOLUTION: A visual recognition object to be viewed by a driver is determined based on an image acquired by a camera 1 and indicative of a surrounding state of a vehicle as a moving body. The determination of the visual recognition object is made based on a saliency model considering something to be visually recognized the instant something is viewed as the visual recognition object, a surprise model considering abnormal movements as the visual recognition object, and a normative model considering what is visually recognized by a driver's visual recognition behavior serving as a good example as the visual recognition object. The visual recognition object not present in a driver's visual line direction to be detected by an eye camera 2 is deemed as the visual recognition object happening to be missed, and the driver's visual line is guided towards a direction where missing happens (an index is displayed at a location of an object of attention happening to be missed.)SELECTED DRAWING: Figure 1
【課題】運転者が視認すべき視認対象物を確実に検出する。検出した視認対象物を運転者に対して確実に視認させる。【解決手段】カメラ1によって取得された移動体としての自動車の周囲状況を示す画像に基づいて、運転者が見るべき視認対象物が決定される。視認対象物の決定が、見た瞬間に視認されるものを視認対象物とするサリエンシーモデルと、異常な動きを行うものを視認対象物とするサプライズモデルと、お手本となる運転者の視認行動によって視認されるものを視認対象物とする規範モデルと、に基づいて行われる。アイカメラ2によって検出される運転者の視線方向にない視認対象物が、見落としとなる視認対象物とされて、この見落としとなる視認対象物の方向へ運転者の視線が誘導される(見落としとなる注意対象物の位置に指標を表示する)。【選択図】図1
