The imaging lens group includes at least one lens, and the sheet-like shading element includes at least two layers of structure and a plurality of columnar air structures, wherein the lens can be a molded glass or plastic lens, and the columnar air structure can be arranged in an array, but is not limited thereto. The thickness of the sheet-like shading element is Dt, and the depth of each columnar air structure is d, which satisfies the following condition: 0.1≤d / Dt≤1. Specifically, the sheet-like shading element can make non-imaging light less likely to be generated, thereby reducing the glare problem.

[0115] The sheet-like shading element can maintain an air distance with the lens, and the layer structure can be arranged opposite to the lens, wherein the columnar air structure is farther away from the lens than a surface of the sheet-like shading element, and the surface of the sheet-like shading element faces the lens.

[0116] Furthermore, the imaging lens module may further include at least one optical path turning element, wherein the optical path turning element causes the optical axis to turn at least once, and the optical path turning element has a light incident surface, a light exiting surface, and at least one optical reflection surface. The sheet-like shading element may maintain an air distance from the optical path turning element, and the layer structure may be arranged opposite to the optical path turning element, wherein the columnar air structure is farther away from the optical path turning element than a surface of the sheet-like shading element, and the surface of the sheet-like shading element faces the optical path turning element. Accordingly, the columnar air structure may conduct the air gap between the sheet-like shading element and the optical path turning element.

[0117] The number of the layer structure of the sheet-shaped shading element can be two. When the number of the layer structure is only two, along the direction parallel to the optical axis, the covering layer is located above the base layer, or the covering layer is located below the base layer. Furthermore, the base layer can be a plastic material, or a metal material, such as brass, cold-rolled steel, etc., but is not limited thereto.

[0118] The sheet-shaped shading element may further include a light-transmitting structure, wherein the light-transmitting structure is arranged correspondingly to the light path turning element. Thus, the light-transmitting structure allows light entering or exiting the light-entering surface or the light-exiting surface to pass through. Alternatively, the light-transmitting structure is arranged correspondingly to the lens. Thus, the generation of additional non-imaging light can be avoided. Specifically, the light-transmitting structure allows light entering or exiting the lens to pass through.

[0120] The light path turning element can be a prism, wherein the prism can be a plastic prism or a glass prism. Further, the plastic prism can be made by injection molding, and the glass prism can be made of molded glass material, but it is not limited thereto.

[0121] The thickness of the sheet-shaped light-shielding element is Dt, and the depth of each columnar air structure is d, which can satisfy the following condition: 0.30≤d / Dt≤0.95. Thus, the production yield can be improved.

[0122] The layer structure may include at least one coating layer and at least one base layer, wherein the sum of the thickness of one of the coating layers and the thickness of one of the base layers is Dm, and the thickness of the sheet-shaped shading element is Dt, which may satisfy the following condition: 0.5≤Dm / Dt≤1. Thus, the process efficiency may be improved. It must be noted that the number of the coating layer and the base layer may be multiple.

[0123] Specifically, when the number of layer structures is two or more, the coating layer is located above the base layer in the direction parallel to the optical axis, but it is not limited thereto. Furthermore, when the number of coating layers is two and they are the first coating layer and the second coating layer respectively, the thickness of the first coating layer is D1, the thickness of the second coating layer is D2, and the thickness of the base layer is Db, wherein the sum of the thickness of one of the coating layers and the thickness of one of the base layers refers to the sum of the thickness D1 of the first coating layer and the thickness Db of the base layer; when the number of coating layers is one, the thickness of the coating layer is D, and the thickness of the base layer is Db, wherein the sum of the thickness of one of the coating layers and the thickness of one of the base layers refers to the sum of the thickness D of the coating layer and the thickness Db of the base layer.

[0124] The diameter of each columnar air structure is Dc, which can meet the following conditions: 0.005mm≤Dc≤0.021mm. This can provide a higher precision process. In addition, it can meet the following conditions: 0.007mm≤Dc≤0.017mm.

[0125] The distance between two adjacent columnar air structures is Ds, which can meet the following conditions: 0.01mm≤Ds≤0.25mm. By controlling the spacing within a specific range, a wider range of stray light elimination effects can be provided. In addition, it can meet the following conditions: 0.01mm≤Ds≤0.10mm. In this way, the efficiency of eliminating stray light can be improved.

[0126] The depth of each columnar air structure is d, which can satisfy the following condition: 0.01 mm ≤ d ≤ 0.10 mm. This helps to destroy stray light.

[0127] The surface area of ​​the sheet-shaped shading element is A, and the area of ​​the region of the surface of the sheet-shaped shading element having the columnar air structure is Ad, which can satisfy the following condition: 0.005≤Ad / A≤1. Thus, a higher imaging quality can be provided, and stray light can be effectively eliminated. In addition, the following condition can be satisfied: 0.005≤Ad / A≤0.750. Thus, production efficiency can be improved while maintaining a certain imaging quality.

[0128] The light-transmitting structure may include a light-shielding structure, wherein the light-shielding structure presents a plurality of protrusions, and the average maximum height of the light-shielding structure is h, which may satisfy the following condition: 0.001 mm ≤ h ≤ 0.050 mm.

Specifically, the viewing angle θ can satisfy the following condition: 40 degrees < θ < 90 degrees. In this way, image information within the left and right lanes can be captured.

[0205] Depend on Fig. 12B It can be seen that the other two of the camera modules 1210 can be set in the space inside the vehicle tool 1200. Specifically, the two camera modules 1210 are respectively set near the position of the rearview mirror inside the vehicle and near the rear window. Furthermore, the camera modules 1210 can also be respectively set on the non-mirror surface of the left and right rearview mirrors of the vehicle tool 1200, but it is not limited thereto.

[0206] Depend on Fig. 12C It can be seen that two of the camera modules 1210 can be set at the front and rear ends of the vehicle tool 1200. The configuration of the camera modules 1210 at the front and rear ends of the vehicle tool 1200 and below the left and right rearview mirrors can help the driver obtain external space information outside the cockpit, such as external space information I1, I2, I3, and I4, but not limited to this. In this way, more viewing angles can be provided to reduce blind spots, thereby helping to improve driving safety. Furthermore, by setting the camera modules 1210 around the vehicle tool 1200, it is helpful to identify road condition information outside the vehicle tool 1200, so as to help realize the function of automatic assisted driving.

[0207] Although the present invention has been disclosed as above by means of implementation modes and examples, they are not intended to limit the present invention. Any person with ordinary knowledge in the technical field may make slight changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention shall be determined by the definition of the attached claims.
