[0100] One aspect of the present disclosure provides an imaging lens module having an imaging surface (Image Surface) and comprising an optical lens, a plurality of monomer structures (Monomer Structure) and a cover member (Cover Member). The optical lens is arranged on the object side of the imaging surface and defines an optical axis. The optical lens includes a shading element, which includes a shading portion, and the shading portion is closer to the optical axis than the portion of the shading element other than the shading portion. The monomer structures are arranged on the object side of the imaging surface, and each monomer structure extends along a direction parallel to the optical axis. The cover member is arranged on the object side of the optical lens, and the optical axis passes through the cover member. The monomer structure is arranged on the shading portion of the shading element. The length of each monomer structure along the direction parallel to the optical axis is D, and the spacing distance between the monomer structures is Dp, which satisfies the following conditions: 0.03mm≤D<0.12mm; and 0.02mm≤Dp<0.095mm.

[0101] Furthermore, Examples 1 to 5 of the first embodiment of the present disclosure may serve as examples of the aforementioned imaging lens module. The multiple monomer structures extend parallel to the optical axis and may be convex cylindrical structures extending a certain height from one surface of the light shielding portion, or concave cylindrical structures recessed a certain depth from one surface of the light shielding portion toward another surface, but are not limited thereto. The outer cover element may be made of, but is not limited to, a transparent material such as plastic or glass. The light shielding element may be, but is not limited to, a lens barrel, a fixing ring, a spacer ring, a light shielding sheet, etc.

[0102] Furthermore, in a miniaturized imaging lens module, the distance between the outer cover element and the light shielding element is short, which may easily cause unnecessary optical reflections (e.g. Figure 1D and Figure 8D The reflected light is the flare. Therefore, the present disclosure employs methods such as injection molding or laser beam processing to place multiple monomer structures on a specific area of ​​the light shielding portion, thereby reducing the reflectivity of light in that specific area.

[0103] One aspect of the present disclosure provides an imaging lens module having an imaging surface and including an optical lens, a light-shielding element, a plurality of monomeric structures, and an outer cover element. The optical lens is disposed on the object side of the imaging surface and defines an optical axis. The light-shielding element is disposed opposite to the optical lens and includes a light-shielding portion, and the light-shielding portion is closer to the optical axis than the portion of the light-shielding element other than the light-shielding portion. The monomeric structures are disposed on the object side of the imaging surface, and each monomeric structure extends along a direction parallel to the optical axis. The outer cover element is disposed on the object side of the optical lens, and the optical axis passes through the outer cover element. The monomeric structures are disposed on the light-shielding portion of the light-shielding element. The length of each monomeric structure along the direction parallel to the optical axis is D, and the spacing distance between the monomeric structures is Dp, which satisfy the following conditions: 0.03 mm ≤ D < 0.12 mm; and 0.02 mm ≤ Dp < 0.095 mm. Thereby, the plurality of monomeric structures can disrupt the reflection path of non-imaging light and prevent non-imaging light from entering the optical lens, thereby making the image画面 clear.

[0104] Furthermore, a second embodiment of the present disclosure can be an example of the foregoing imaging lens module. The imaging lens module can further include a variable aperture module, which is disposed on the object side of the optical lens, and the optical axis passes through the center of the variable aperture module. The variable aperture module includes at least two of the light-shielding elements, and each light-shielding element is stacked on each other along a circumferential direction around the optical axis to form a variable aperture, and the present disclosure is not limited thereto.

[0105] Specifically, the number of the monomeric structures is Nm, which can satisfy the following conditions: 250 < Nm < 25000. Thereby, the set range of the number can enable the monomeric structures to have a better light-shielding effect.

[0106] The light-shielding portion can face the object side of the optical lens. Thereby, this configuration helps the light-shielding portion to have a better efficiency of intercepting non-imaging light.

[0107] The light-shielding element can extend along the direction parallel to the optical axis. The light-shielding element can further include an object-side surface, which is located at the outermost object-side portion of the light-shielding element. The object-side surface can face the object side of the optical lens.

[0108] The height difference along the direction parallel to the optical axis between the object-side surface and the setting surface of the monomeric structure is ΔH, and the length of the light-shielding element along the direction parallel to the optical axis is Lb, which can satisfy the following conditions: 0 ≤ ΔH / Lb < 0.8. Thereby, the continuity of the coverage range of the monomeric structures can be ensured to maintain a high light-shielding effect.

[0109] The monomeric structures can face the object side of the optical lens. Thereby, this configuration helps the monomeric structures to have a better light-shielding effect.

[0110] The outer cover element can correspond to and face the light-shielding portion of the light-shielding element. Thereby, this configuration helps the light-shielding portion to have a better efficiency of intercepting non-imaging light.

[0111] The light-shielding element may be composed of at least two structural layers. Specifically, the light-shielding element may be a light-shielding sheet, but is not limited thereto. The at least two structural layers may include a base layer and a covering layer.

[0112] The thickness of the base layer is Ts, and the thickness of the covering layer is Tc, which may satisfy the following condition: 0.03 mm ≤ D < Ts + Tc < 0.5 mm. Thereby, this range is a preferable thickness setting range that takes into account both the light-shielding effect of the monomer structure and the production efficiency of the light-shielding element.

[0113] Each technical feature in the imaging lens module of the above disclosure can be combined and configured to achieve the corresponding effects.

[0114] One aspect of the disclosure provides a camera module, including the aforementioned imaging lens module.

[0115] One aspect of the disclosure provides an electronic device, including the aforementioned camera module.

[0169] <Third embodiment>

[0170] Please refer to Figure 9A and Figure 9B ,in Figure 9A FIG. 1 is a schematic diagram illustrating an electronic device 30 according to a third embodiment of the present disclosure. Figure 9B Drawing in accordance with Figure 9A Another schematic diagram of the electronic device 30 of the third embodiment. Figure 9A and Figure 9BAs can be seen, electronic device 30 is a smartphone, comprising a camera module according to the present disclosure, which includes an imaging lens module according to the present disclosure and may include an electronic photosensitive element, wherein the electronic photosensitive element is disposed on the imaging surface of the imaging lens module and is used to receive imaging light from the imaging lens module. Specifically, the camera modules are an ultra-wide-angle camera module 322, a high-pixel camera module 323, and a telephoto camera module 324, and the user interface 321 is a touch screen, but the present disclosure is not limited thereto. Specifically, the camera module may be any of the camera modules described in the first and second embodiments, but the present disclosure is not limited thereto.

[0171] The user interface 321 has a touch function and allows the user to enter the shooting mode through the user interface 321. The user interface 321 is used to display the image and can be used to manually adjust the shooting angle to switch between different camera modules. At this time, the camera module focuses imaging light on the electronic photosensitive element and outputs an electronic signal related to the image to the image signal processing unit (ISP) 325.

[0172] Depend on Figure 9B It can be seen that, depending on the camera specifications of the electronic device 30, the electronic device 30 may also include an optical image stabilization component (not shown). Furthermore, the electronic device 30 may also include at least one focus assist module (not shown) and at least one sensor element (not shown). The focus assist module may be a flash module that compensates for color temperature, an infrared ranging element, a laser focus module, etc. The sensor element may have the function of sensing physical momentum and actuation energy, such as an accelerometer, a gyroscope, or a Hall Effect Element, to sense shaking and vibration imposed by the user's hand or the external environment. This, in turn, facilitates the autofocus function and optical image stabilization component configured in the camera module of the electronic device 30 to achieve good image quality. This helps the electronic device 30 according to the present disclosure to have multiple shooting modes, such as optimized selfies, low-light HDR (High Dynamic Range) imaging, and high-resolution 4K (4K Resolution) video recording. In addition, the user can directly view the shooting image of the camera through the user interface 321 and manually operate the framing range on the user interface 321 to achieve a what-you-see-is-what-you-get auto-focus function.

Configuring the imaging lens module and related components on a flexible printed circuit board and then integrating the circuits onto the electronic device's mainboard via a connector can meet the structural design and circuit layout requirements within the limited space within the electronic device and provide greater margin. This also allows the camera module's autofocus function to be more flexibly controlled via the electronic device's touch screen. In a third embodiment, the electronic device 30 can include multiple sensor components and multiple focus assist modules. The sensor components and focus assist modules are disposed on the flexible printed circuit board and at least one additional flexible printed circuit board (not shown), and are electrically connected to the imaging signal processing component 325 and other related components via corresponding connectors to execute the shooting process. In other embodiments (not shown), the sensor element and the auxiliary optical element may also be disposed on a mainboard or other types of carrier boards of the electronic device according to the requirements of the mechanical design and circuit layout.

Camera modules 510 can be any of the camera modules described in the first and second embodiments, but the present disclosure is not limited thereto.

[0186] Depend on Figure 11A and Figure 11B As can be seen, the two camera modules 510 are located below the left and right rearview mirrors, respectively, and are used to capture image information within a certain viewing angle θ. Specifically, the viewing angle θ can satisfy the following condition: 40 degrees < θ < 90 degrees. This allows the capture of image information within the left and right lanes.

[0187] Depend on Figure 11B As can be seen, the other two camera modules 510 can be installed in the interior space of the vehicle tool 50. Specifically, the two camera modules 510 are respectively installed near the interior rearview mirror and the rear window. Furthermore, the camera modules 510 can also be installed on the non-mirror surface of the left and right rearview mirrors of the vehicle tool 50, but this is not limited to this.

[0188] Depend on Figure 11C As can be seen, two of the camera modules 510 can be installed at the front and rear ends of the vehicle tool 50. The placement of the camera modules 510 at the front and rear ends of the vehicle tool 50 and below the left and right rearview mirrors helps the driver obtain information about the external space outside the cockpit, such as, but not limited to, external space information I1, I2, I3, and I4. This provides more viewing angles, reduces blind spots, and thus helps improve driving safety. Furthermore, by placing the camera modules 510 around the vehicle tool 50, it helps identify road conditions outside the vehicle tool 50, thereby facilitating automated assisted driving.

[0189] Although the present invention has been disclosed above by way of implementation methods and examples, they are not intended to limit the present invention. Anyone 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 scope of protection of the present invention shall be determined by the appended claims.
