To provide an on-vehicle imaging system capable of reducing luminance unevenness of an image obtained by irradiating light emitted from a light source at night or in a dark place and displaying an image with good visibility.SOLUTION: An on-vehicle imaging system includes a camera 11 including an image sensor 111 having sensitivity to a light source, a wavelength region of light emitted from the light source, and a visible light region; and a physical property element 112, disposed on a light incident side of the imaging sensor, for adjusting a light quantity of the incident light in the incident wavelength region and emitting the light. When imaging using a light source, the physical property element 112 is in a state of having a transmittance distribution that cancels the light quantity distribution of incident light incident on the physical property element 112. When imaging without using a light source, the physical property element 112 is in a state of transmitting visible light.SELECTED DRAWING: Figure 2

    【課題】夜間や暗所において、光源からの出射光を照射して得られる画像の輝度ムラを低減し、視認性の良い画像を表示できる車載用撮像システムを提供する。【解決手段】車載用撮像システムは、光源と光源の出射光の波長領域と可視光領域とに感度を有する撮像素子111と、撮像素子の光入射側に配置され、入射した波長領域の入射光の光量を調節して出射する物性素子112と、を備えたカメラ11を備える。光源を用いて撮像する際には、物性素子112が、物性素子112に入射する入射光の光量分布を解消する透過率分布を有する状態をとり、光源を用いずに撮像する際には、物性素子112が可視光を透過する状態をとる。【選択図】図2
