PROBLEM TO BE SOLVED: To accurately detect foreign substance attaching to the front glass of a vehicle.SOLUTION: An imaging device includes an imaging optical system, an imaging device, and a processor. The imaging device is arranged so that a part of the window of a vehicle is located between the imaging device and a foreign substance identifying object in the vehicle, includes the foreign substance identifying object and the part of the window in an imaging range, and is arranged so that the straight line connecting a surface of the imaging optical system which is the closest to the foreign substance identifying object and the foreign substance identifying object is along the surface of the part of the window. The processor detects foreign substance attaching on the window based on an image of at least a part of the foreign substance identifying object taken by the imaging device.SELECTED DRAWING: Figure 1
【課題】車両のフロントガラスに付着した異物を正確に検出する。【解決手段】撮像光学系を含む撮像装置であって、車両に設けられた異物識別用被写体との間に車両のウィンドウの一部が位置するように配置され、該異物識別用被写体と車両のウィンドウの一部とを撮像範囲に含み、撮像光学系の最も異物識別用被写体側の面と異物識別用被写体とを結ぶ直線が、ウィンドウの一部の表面に沿うに配置された撮像装置と、撮像装置によって異物識別用被写体の少なくとも一部が撮像された画像に基づいて、ウィンドウに付着した異物を検出するプロセッサと、を備える。【選択図】図1
