To provide a line-of-sight detection device suitable for use in an environment with disturbance.SOLUTION: Provided are a camera 13 for acquiring a face image of a subject person, face orientation detection means 23 for detecting the face orientation from the face image, and line-of-sight detection means 21 for extracting a pupil from the face image and detecting the line of sight. While the detection result of the face orientation detection means 23 and the detection result of the line-of-sight detection means 21 are respectively updated at predetermined time intervals, an output correcting unit 23 obtains a difference between an update detection result newly acquired by the face orientation detection means 23 and a detection result before updating as a face-orientation displacement, obtains a difference between an update detection result newly acquired by the line-of-sight detection means 21 and a detection result before updating as a line-of-sight displacement, and compares the face-orientation displacement and the line-of-sight displacement and then corrects an output value of the face-orientation displacement or an output value of the line-of-sight displacement.SELECTED DRAWING: Figure 2
【課題】外乱のある環境下での使用に適した視線検知装置を提供する。【解決手段】対象者の顔画像を取得するカメラ13と、顔画像から顔向きを検出する顔向き検出手段23と、顔画像から瞳孔を抽出して視線を検出する視線検出手段21と、を備え、顔向き検出手段23の検出結果と視線検出手段21の検出結果とが、それぞれ所定の時間間隔で更新され、顔向き検出手段23によって新規に取得した更新検出結果と更新前の検出結果との差分を顔向き変位とし、視線検出手段21によって新規に取得した更新検出結果と更新前の検出結果との差分を視線変位として、顔向き変位と視線変位とを比較して顔向き変位の出力値又は視線変位の出力値を補正する出力補正部23を備える.【選択図】図2
