To allow for estimating driver's concentration on driving by considering a plurality of gaze states.SOLUTION: A gaze point determination part 36 determines which of a plurality of types of gaze states a gaze state of a driver is based on a set front gaze point, a detected driving attention point, and a detected line of site of the driver. A concentrated state estimation part 38 estimates a concentrated state for the driver's driving, based on a ratio of each of determined gaze states and a detected duration of the gaze.SELECTED DRAWING: Figure 1
【課題】複数の注視状態を考慮して、ドライバの運転に対する集中状態を推定できる。【解決手段】注視点判別部36は、設定した前方注視点と、検出した運転注意点と、検出したドライバの視線とに基づいて、ドライバの注視の状態が、複数種類の注視状態の何れであるかを判別する。集中状態推定部38は、判別された注視状態の各々の割合と、検出された注視の継続時間とに基づいて、ドライバの運転に対する集中状態を推定する。【選択図】図1
