The invention relates to an imaging device, a vehicle lamp system, and an imaging lens, which can suppress the reduction of imaging precision caused by the center deviation of the incident position of light relative to the central axis of the imaging lens and the reduction of the number of light receiving elements for receiving light. An imaging device is provided with: an imaging element having a light receiving surface on which a plurality of light receiving elements are arranged; and an imaging lens that transmits light from the outside and forms light spots on the light receiving surface of the imaging element. The light-receiving surface of the imaging element is disposed at a position offset in the central axis direction of the imaging lens with respect to the light-focusing position of the imaging lens. The area of a first spot formed on the light receiving surface by light incident parallel to the central axis of the imaging lens to an arbitrary position in a target region from the center of the imaging lens to a predetermined distance in the radial direction is the same as the area of a basic spot formed on the light receiving surface by light incident parallel to the central axis of the imaging lens to the central axis.
本发明涉及拍摄装置、车灯系统以及拍摄透镜,能够对由光的入射位置相对于拍摄透镜的中心轴的中心偏离、以及受光的受光元件的数量的降低导致的拍摄精度的降低进行抑制。拍摄装置具备:拍摄元件,其具有配置有多个受光元件的受光面;以及拍摄透镜,其使来自外部的光透过而在拍摄元件的受光面形成光的光点。拍摄元件的受光面配置于相对于拍摄透镜的聚光位置而在拍摄透镜的中心轴向上偏离的位置。平行于拍摄透镜的中心轴而入射至从拍摄透镜的中心沿径向到预定距离为止的对象区域的任意位置的光在受光面形成的第一光点的面积、与平行于拍摄透镜的中心轴而入射至中心轴的光在受光面形成的基本光点的面积相同。
