| description | To enable an inexpensive system to easily determine whether an image acquired by a camera is a true image in which an actually driving driver itself is photographed when a member for making a false image photographed is disposed between the camera and the driver.SOLUTION: By a camera S1, an image in a vehicle interior including a facial surface of a driver D seated on a driver seat 4 is acquired. A driver state is estimated based on the acquired image by the camera S1. In a photographing range K of the camera S1 of the vehicle interior, identification tags α1 to α5 for showing that the image is true are provided. Whether the acquired image is the true image or a non-true image is determined in accordance with presence or absence of the image showing the identification tag in the image acquired by the camera S1. When it is determined that the image is non-true, the estimation of the driver state is inhibited.SELECTED DRAWING: Figure 3
【課題】カメラとドライバとの間に偽画像を撮影させるための部材が配設された場合に、安価なシステムでもって、カメラによって取得された画像が実際に運転を行っている本人が撮影されている真性なものであるか否かを容易に判定できるようにする。【解決手段】カメラＳ１によって、運転席４に着座されたドライバＤの顔面を含む車室内の画像が取得される。カメラＳ１によって取得された画像に基づいて、ドライバ状態が推定される。車室内のうちカメラＳ１の撮影範囲Ｋに、真性な画像であることを示すための識別タグα１〜α５が設けられる。カメラＳ１によって取得された画像中における識別タグを示す画像の有無に応じて、取得された画像が真性な画像か非真性な画像であるかが判定される。画像が非真性であると判定されたときは、ドライバ状態の推定が禁止される。【選択図】 図３ |
