DETAILED DESCRIPTION

[0022] The present disclosure provides a camera module including an imaging lens array, an image sensor, and a magnet mounting mechanism. The image sensor is for receiving an image signal from the imaging lens array. The magnet mounting mechanism is for determining a state of the image signal of the imaging lens array according to the image sensor. The magnet mounting mechanism includes a magnet holder, a magnet, and an opaque layer. The magnet is disposed on the magnet holder. The opaque layer is attached to an outer surface of the magnet. Thus, the present disclosure provides the camera module with the magnet and the surface of the magnet with the opaque layer, which is beneficial for reducing the possibility of generating stray light by providing the matte magnet to prevent the surface of the magnet from having a metallic luster.Furthermore, since the state of the image signal of the imaging lens assembly would be changed by movement between mechanisms such as the magnetic mounting mechanism, some of the light in the camera module would result in a situation that is unexpected for light simulation. Therefore, the design of the present disclosure is advantageous for ensuring the quality of the image signal by reducing the possibility of the above situation.

[0023] In particular, the magnet mounting mechanism may be a dynamic moving coil drive mechanism or a rotating magnet drive mechanism. The dynamic moving coil drive mechanism may have a fixed magnet holder or both a movable magnet holder and a fixed magnet holder. The rotating magnet drive mechanism may have a movable magnet holder or both a movable magnet holder and a fixed magnet holder. The present disclosure is not limited thereto.

[0024] The state determined by the magnetic mounting mechanism is that the magnetic mounting mechanism can be configured to ensure the autofocus function of the camera module, the image stabilization of the camera module, the aperture adjustment function of the camera module, and the circuit control function of the camera module: that is, the above-mentioned functions are particular embodiments for determining the state of the image signal of the imaging lens assembly relative to the image sensor, and the present disclosure is not limited thereto.

[0025] In addition, the magnet may be attached to the magnet holder by adhesive or may be directly magnetically attached to the magnet holder, but the present disclosure is not limited to this.

[0026] The opaque layer may have a portion facing toward the image sensor. Since high-intensity non-imaging light is easily generated at the location where the magnetic mounting mechanism is close to the image sensor, it is advantageous for effectively preventing non-imaging light from falling onto the image sensor.

[0027] The magnet mounting mechanism may further comprise a coil, wherein the magnet and the coil are arranged relative to each other. Therefore, a driving force for the magnet mounting mechanism can be generated by appropriately arranging the magnet and the coil, ensuring the dynamic change of the image signal.

[0028] The magnet mounting mechanism may further comprise a magnetic sensor element, wherein the magnet and the magnetic sensor element are arranged relative to each other. This is advantageous for controlling the sensitivity of the magnet mounting mechanism.

[0029] The magnetic mounting mechanism is used to adjust the relative position of the imaging lens assembly and the image sensor. This is advantageous for implementing the autofocus function or image stabilization. If the imaging lens assembly and the image sensor can be moved relative to each other in a vertical and parallel direction, this can lead to the implementation of the autofocus function or image stabilization.

[0030] The magnetic mounting mechanism serves to generate a biasing force to support the imaging lens assembly. Specifically, the relative position of the imaging lens assembly and the image sensor can be maintained in a state of equilibrium by the biasing force. This is beneficial for achieving assembly stability.

[0031] The magnetic mounting mechanism is used to adjust the aperture size of an aperture diaphragm. This is advantageous for achieving the aperture adjustment function through the adjustable aperture diaphragm.

[0032] Additionally, the magnetic mounting mechanism may include a nanolayer deposited on the opaque layer. This is advantageous for maintaining low surface reflectivity by also placing the nanolayer on top of the opaque layer.

[0033] The nanolayer can comprise a plurality of nanoparticles irregularly arranged on a surface of the opaque layer. The gradual refractive index can thus be created by stacking the nanoparticles in such a way that the reflectivity is reduced.

[0034] The nanolayer may comprise a plurality of nanoprotrusions irregularly arranged on a surface of the opaque layer. This is advantageous for ensuring a coating process with good suitability for mass production.

[0035] The nanolayer can comprise a multitude of nanoholes irregularly arranged on a surface of the opaque layer. The gradual refractive index can thus be created by stacking the nanoparticles in such a way that the reflectivity decreases.

[0036] The opaque layer may comprise a plurality of micron particles to create an irregularly protruding structure on a surface of the opaque layer. This is advantageous for providing a surface of the magnet with lower reflectivity by applying a coating form with better matting ability. Specifically, the micron particles for absorbing incident light may be made of black carbon material, acrylic material, silicon dioxide, siliceous alumina, or metal material. The micron particles may create an irregularly protruding structure on the opaque layer, which is beneficial for reducing the possibility of generating stray light by effectively diffracting the high-intensity incident light. The opaque layer may further comprise an opaque coating material, which is beneficial for increasing its adhesion to attach the micron particles to the magnet.The opaque coating material may consist of, but is not limited to, black pigments, organic solvents, or resins.

[0037] When the surface of the opaque layer is measured according to ISO 25178, Y pd is defined as the number of peaks per square millimeter of the microstructure layer that meets the following condition: 19000 1 / mm 2 ≤ Y pd ≤ 210000 1 / mm 2 . In addition, the following condition can be met: 25000 1 / mm 2 ≤ Y pd ≤ 120000 1 / mm 2 .

[0038] When the surface of the opaque layer is measured according to ISO 25178, an equivalence line and an area-material ratio curve are obtained. A core surface of the profile elements is defined by 0% to 100% of the equivalence line corresponding to the area-material ratio curve. A reduced peak is a section of the area-material ratio curve that is higher than the core surface. Y mr1 is the area-material ratio separating the core surface from the reduced peak, satisfying the following condition: 7% ≤ Y mr1 ≤ 53%. In addition, the following condition can be satisfied: 15% ≤ Y mr1 ≤ 45%.

[0039] When the surface of the opaque layer is measured according to ISO 25178, the equivalence line and the area-material ratio curve are obtained. A core surface of the profile elements is defined by 0% to 100% of the equivalence line corresponding to the area-material ratio curve. The reduced peak is the section of the area-material ratio curve that is higher than the core surface. With Aph for the mean height of the reduced peak, the following condition is satisfied: 0.5 µm ≤ Aph ≤ 42.5 µm. In addition, the following condition can be satisfied: 4.5 µm ≤ Aph ≤ 35.5 µm.

[0040] When the surface area of ​​the opaque layer is measured according to ISO 25178, with Hpq for the number of peaks of the microstructure layer larger than the core surface and larger than 4 µm, the following condition is met: 0 ≤ Hpq ≤ 430. In addition, the following condition can be met: 15 ≤ Hpq ≤ 300.

[0041] The above-mentioned conditions define the measurement according to the ISO 25178 standard of the various partial areas of the opaque layer of the present disclosure, which can exhibit different measurement data. The opaque layer of the present disclosure has at least one part that can satisfy one of the above-mentioned conditions. That is, if the surface roughness parameters can satisfy any of the above-mentioned conditions, the reflection of visible light can be effectively prevented, resulting in a suitable coated surface for use in the camera module.

[0042] In addition, the opaque layer can completely cover the magnet. This is beneficial for the manufacturability of a blackened magnet.

[0043] The present disclosure provides an electronic device including the above-mentioned camera module. <1. Embodiment>
