To improve visibility of a video image displayed by an on-vehicle camera mounted on a vehicle in which a light is provided only one side of the vehicle even if the circumference is under a dark environment.SOLUTION: An on-vehicle camera 20 mounted on a vehicle in which a light ejecting a visible light is provided only one side of a rear direction of the vehicle, includes: an LED 22-1 ejecting the light of a specific wavelength band; an image sensor 41 provided between the light and the LED, and having sensibility in response to at least the visible light and the light of the specific wavelength band; a lens 21 that collects the light scattered from an object to an image sensor; a first optical member 44 provided on an optical path from the object to the image sensor; and a second optical member 45. The first and second optical members penetrate the visible light, and the first optical member suppress the penetration of the light of the specific wavelength band than the second optical member. When mounting the on-vehicle camera onto the vehicle, the second optical member is arranged on the LED side from the first optical member.SELECTED DRAWING: Figure 4

    【課題】周囲が暗い環境下においても、ライトが車両の片側のみに設けられた車両に搭載された車載カメラによって映し出される映像の視認性を向上する。【解決手段】可視光を出射するライトが車両後方の片側のみに設けられた車両に搭載する車載カメラ20であって、特定の波長帯域の光を出射するLED22−1と、ライトとLEDとの間に設けられ、且つ、少なくとも可視光及び特定の波長帯域の光に対して感度を有するイメージセンサ41と、被写体から散乱された光をイメージセンサに集光させるレンズ21と、被写体からイメージセンサまでの光路に設ける第1の光学部材44と、第2の光学部材45とを有する。第1の光学部材と第2の光学部材は可視光を透過し、第1の光学部材は第2の光学部材よりも特定の波長帯域の光の透過を抑制する。また、車載カメラを車両に搭載した場合に、第2の光学部材は、第1の光学部材よりもLED側に配置される。【選択図】図4
