To appropriately assure security and safety of an occupant by appropriately determining whether or not a face of the occupant exists at a normal position.SOLUTION: An occupant face detection device 7 includes: an image acquisition section 21 for acquiring a predetermined area of an image obtained by imaging the periphery of a headrest of a seat of an occupant by an imaging section; a face image determination section 22 for determining whether or not a face image of the occupant exists in the predetermined area of the image; a background image determination section 23 for determining whether or not a background image exists in the predetermined area of the image; and a face existence determination section 26 for determining whether or not the face of the occupant exists at a normal position based on a determination result of the face image determination section. The face existence determination section determines that the face of the occupant exists at the normal position when it is determined that the face image of the occupant exists in the predetermined area of the image, and determines that the face of the occupant does not exist at the normal position based on a determination result of the background image determination section when it is determined that the face image of the occupant does not exist in the predetermined area of the image.SELECTED DRAWING: Figure 1

    【課題】乗員の顔が正常位置に存在しているか否かを適切に確定し、乗員の安心安全を適切に確保する。【解決手段】乗員の顔検出装置7は、撮像部が乗員の座席のヘッドレスト周辺を撮像した画像の所定領域を取得する画像取得部21と、画像の所定領域に乗員の顔画像が存在しているか否かを判定する顔画像判定部22と、画像の所定領域に背景画像が存在しているか否かを判定する背景画像判定部23と、顔画像判定部の判定結果により乗員の顔が正常位置に存在しているか否かを確定する顔存在確定部26と、を備える。顔存在確定部は、画像の所定領域に乗員の顔画像が存在していると判定されると、乗員の顔が正常位置に存在していることを確定し、画像の所定領域に乗員の顔画像が存在していないと判定されると、背景画像判定部の判定結果に基づいて乗員の顔が正常位置に存在していないことを確定する。【選択図】図1
