[0042] This disclosure provides a camera module, see [link]. Figure 1 As shown, it includes a shelf 20, a flash lamp 10, a light-transmitting area 30, and a light sensor 40;

[0043] Flashlight 10 is disposed on the first surface 211 of shelf 20;

[0044] The light-transmitting area 30 is located in the area of ​​the shelf 20 adjacent to the flash, and is used to transmit ambient light.

[0045] A light sensor 40 is disposed on the second surface 212 of the shelf 20 away from the first surface 211 and opposite to the light-transmitting area 30, for collecting ambient light.

[0046] Understandably, the shelf 20 is the basic structure of the camera module, used to fix and support other components. The shelf 20 has two surfaces, a first surface 211 and a second surface 212 arranged opposite to each other; the flash 10 is disposed on the first surface 211 of the shelf 20 to provide an auxiliary light source in low light conditions to improve the photo-taking effect.

[0047] The light-transmitting area 30 is located on the shelf 20 near the flash lamp 10. The light-transmitting area 30 is an area that allows ambient light to pass through. It can be made of transparent material, or it can be a tiny hole, a transparent film, etc., to ensure that ambient light can pass through smoothly.

[0048] A light sensor 40 is disposed on the second surface 212 of the layer plate 20 and corresponds to the light-transmitting area 30. The light sensor 40 receives ambient light through the light-transmitting area 30 and converts the intensity information of the collected ambient light into an electrical signal, which is transmitted to the processing unit for adjusting camera parameters such as exposure and white balance to optimize the image quality. The light sensor 40 can be a photodiode, a phototransistor, or a digital light sensor, etc.

[0049] For example, when ambient light shines on the light-transmitting area 30, the light will pass through the light-transmitting area 30 and reach the light sensor 40. The light sensor 40 converts the received light into an electrical signal and transmits it to the processing unit of the device.

[0050] The device's processing unit adjusts the camera's exposure, white balance, and other parameters using a preset algorithm based on the electrical signal provided by the light sensor 40, in order to optimize the photo-taking effect.

[0051] In low-light conditions, the flash 10 can provide an additional light source to help improve photo quality. The flash 10 can also be intelligently controlled to turn on and off based on the ambient light intensity collected by the light sensor 40.

[0052] Camera modules can be used in smartphones, tablets, or professional photography equipment to provide more accurate ambient light perception and improve photo quality.

[0053] The light-transmitting area 30 is seamlessly integrated with the overall appearance of the device, preserving its aesthetics. Furthermore, through the selection of appropriate materials and design, the light-transmitting area 30 can be highly concealed, almost imperceptible to the user. The light-transmitting area 30 and the light sensor 40 enable the device to more accurately perceive ambient light, thereby optimizing photo quality. This not only enhances the device's aesthetic design but also improves its photographic performance, providing a better user experience.

[0054] In some embodiments, the shelf 20 includes a first shelf 21 and a second shelf 22, a first surface 211 is one side of the first shelf 21, a second surface 212 is the side of the first shelf 21 opposite to the first surface 211, a flash lamp 10 is disposed on the first surface 211, and a light-transmitting area 30 is disposed in the area of ​​the first shelf 21 adjacent to the flash lamp 10.

[0055] The second layer plate 22 is parallel to the first layer plate 21. The light sensor 40 is disposed on the second layer plate 22 and faces the third surface 221 of the second surface 212.

[0056] Understandably, the first layer board 21 can be the PCB circuit board of the flash lamp 10. The first surface 211 of the first layer board 21 faces the outside of the device and is used to mount the flash lamp 10 and related components. The second surface 212 faces away from the first surface 211 and towards the inside of the device, and is opposite to the second layer board 22. The flash lamp 10 can be directly soldered or mounted on the first surface 211 to provide an auxiliary light source in low-light conditions and improve the photography effect.

[0057] The light-transmitting area 30 is located in the area of ​​the first layer plate 21 near the flash lamp 10. The light-transmitting area 30 can be a hole structure. By opening tiny holes in the first layer plate 21, ambient light is allowed to pass through the holes and illuminate the light sensor 40 on the second layer plate 22.

[0058] The light-transmitting area 30 can also be a transparent cover layer, by providing a transparent material, such as transparent resin or transparent film, on the first layer plate 21 to allow ambient light to pass through.

[0059] The light-transmitting area 30 can also be hollowed out. By hollowing out the first layer plate 21, a transparent window is formed to allow ambient light to pass through.

[0060] The second layer board 22 can be a PCB circuit board or a flexible circuit board. The third surface 221 of the second layer board 22 faces the second surface 212 of the first layer board 21 and is used to install the light sensor 40 so that the light sensor 40 is opposite to the second surface 212 of the first layer board 21. The light sensor 40 receives ambient light through the light-transmitting area 30 and converts it into an electrical signal to optimize the photo-taking effect.

[0061] By integrating the flash 10 onto the first layer 21, the overall structure can be simplified, the number of components reduced, and assembly efficiency improved. By placing the light sensor 40 on the second layer 22, the internal space of the device can be fully utilized, resulting in a compact overall structure that facilitates miniaturization and weight reduction.

[0062] In some embodiments, a light-diffusing layer 50 is also included. The light-diffusing layer 50 is disposed on the first surface 211 and covers the light-transmitting area 30 so that ambient light is uniformly directed onto the photosensitive area of ​​the light sensor 40.

[0063] Understandably, in order to make the ambient light shine evenly on the photosensitive area of ​​the light sensor 40, a light-diffusing layer 50 is provided on the first surface 211 of the first layer plate 21, and the light-diffusing layer 50 covers the light-transmitting area 30.

[0064] The light uniformity layer 50 is used to evenly distribute ambient light, reduce light inhomogeneity and interference, and ensure that the light sensor 40 can receive uniform ambient light.

[0065] The light-diffusing layer 50 can be a thin sheet attached to the first surface 211 of the first layer plate 21, covering the light-transmitting area 30. The light-diffusing layer 50 can be an optical diffusion film, an optical diffusion sheet, or a transparent silicone material.

[0066] When ambient light illuminates the light-transmitting area 30, the light first passes through the light-diffusing layer 50, which distributes the light evenly, reducing unevenness and interference. The evenly distributed light passes through the light-transmitting area 30, through the first layer plate 21 and the space between the first layer plate 21 and the second layer plate 22, and finally reaches the photosensitive area of ​​the light sensor 40 located on the third surface 221 of the second layer plate 22. The light is then converted into an electrical signal and transmitted to the processing unit of the device.

[0067] With the efficient light-transmitting area 30 and the high-sensitivity light sensor 40, coupled with the uniform light distribution of the light-diffusing layer 50, the device can more accurately sense ambient light, thereby better optimizing the photo-taking effect.

[0068] In some embodiments, see Figure 2 (a) and Figure 2 As shown in (b), the light-transmitting area 30 has a hole structure and penetrates the first surface 211 and the second surface 212.

[0069] Understandably, in order to enable ambient light to be efficiently transmitted to the light-sensing area of ​​the light sensor 40, the light-transmitting area 30 is set as a hole structure.

[0070] The hole structure can be formed by drilling holes in the first layer plate 21 to form one or more through holes, so that the hole structure penetrates the first surface 211 and the second surface 212 of the first layer plate 21, allowing ambient light to pass through directly.

[0071] The diameter and number of holes can be adjusted according to actual needs. Smaller hole diameters reduce the impact on the appearance of the equipment, while more holes improve light transmission efficiency. Generally, the hole diameter is between 0.1mm and 1mm, and the number can be determined based on the sensitivity of the light sensor 40 and the required light intensity.

[0072] The aperture structure of the light-transmitting area 30 can be set near the flash lamp 10 to ensure that both ambient light and the light from the flash lamp 10 can pass through effectively. This reduces the complexity of the light path and improves the efficiency of light transmission.

[0073] See Figure 2 As shown in (b), the aperture structure can also be distributed at different locations in the light-transmitting area 30 to ensure uniform light distribution. For example, an array layout can be used to make the spacing between each aperture equal, thereby achieving more uniform light collection.

[0074] To prevent dust from entering the hole, a dustproof net, dustproof film, or light-diffusing layer 50 can be installed above the hole. Among them, using a light-diffusing layer 50 to cover the hole structure not only allows ambient light to enter the perforated structure evenly, but also has a dust-proof effect.

[0075] Dustproof netting or membranes should have good breathability and light transmittance to allow light to pass through. Waterproof materials or coatings can also be added around the openings to ensure that moisture does not enter the equipment, thus fulfilling the equipment's waterproof function.

[0076] In some embodiments, see Figure 3 As shown, the area of ​​the light-transmitting area 30 is not less than the area of ​​the light-sensing area of ​​the light sensor 40, so that ambient light can pass through the light-transmitting area 30 to reach the light-sensing area.

[0077] Understandably, the area of ​​the light-transmitting region 30 is not smaller than the area of ​​the photosensitive region of the light sensor 40, ensuring that sufficient light passes through the light-transmitting region 30 to reach the photosensitive region. This improves the sensitivity and response speed of the light sensor 40, especially under low-light conditions. Furthermore, a larger light-transmitting region 30 reduces uneven light distribution, resulting in more uniform light received by the light sensor 40, thereby improving the accuracy of data acquisition.

[0078] A larger light-transmitting area 30 can reduce localized light obstruction and reflection, enabling the light sensor 40 to more accurately perceive changes in ambient light. A larger light-transmitting area 30 can also provide higher spatial resolution, allowing the light sensor 40 to capture subtle changes in ambient light more precisely, thereby improving the accuracy of image optimization.

[0079] In some embodiments, both the first layer 21 and the second layer 22 are circuit boards. The first layer 21 is provided with a flash lamp 10 and a power management circuit, and the light sensor 40 is electrically connected to the circuit board. The circuit board includes at least one of a rigid circuit board and a flexible circuit board.

[0080] Understandably, the first layer 21 and the second layer 22 can be rigid circuit boards, typically made of FR-4 (epoxy fiberglass board), which has good electrical properties and mechanical strength, suitable for high-density wiring and high-power components. Alternatively, the first layer 21 and the second layer 22 can be flexible circuit boards (FPC): made of polyimide (PI), which are thin, light, and flexible, suitable for complex structures requiring bending and folding.

[0081] The flash 10 can be directly soldered or mounted on the first surface 211 of the first layer board 21. It can be positioned close to the camera to provide an auxiliary light source for optimal fill light effect. The flash 10 can be an LED light. The power management circuit is integrated on the first layer board 21 and is responsible for powering the flash 10 and other components. The power management circuit may include a voltage regulator, filter, protection circuit, etc., to ensure a stable power supply and protection functions.

[0082] The power management circuit supplies power to the light sensor 40 and other electronic components on the second-layer board 22 via electrical connections. The ambient light data collected by the light sensor 40 is transmitted to the processing unit via electrical connections for further signal processing and algorithm optimization.

[0083] In some embodiments, an anti-reflective coating is provided at the edge of the light-transmitting area 30 to reduce the reflection loss of ambient light.

[0084] Understandably, to improve the acquisition efficiency and accuracy of the light sensor 40, an anti-reflective coating is used to reduce reflection loss. When light enters from one medium to another, some light is reflected at the interface, resulting in light loss. This reflection loss reduces the intensity of light reaching the light sensor 40, affecting its acquisition accuracy. The anti-reflective coating is an optical coating that reduces light reflection at the edge of the light-transmitting area 30, allowing more light to pass through the light-transmitting area 30 and reach the photosensitive area of ​​the light sensor 40.

[0085] Anti-reflective coatings can consist of multiple thin films, each with precisely calculated thickness and refractive index to achieve optimal anti-reflective performance. Commonly used materials include silica. Nanoscale materials, such as nano-silica and carbon nanotubes, can further enhance the anti-reflective effect.

[0086] The anti-reflective coating can be applied using physical vapor deposition (PVD), chemical vapor deposition (CVD), or sol-gel methods.

[0087] In some embodiments, the homogenization layer 50 is provided with Fresnel patterns.

[0088] Understandably, Fresnel ripples are an optical structure composed of a series of concentric rings or straight lines, which can effectively change the direction and distribution of light propagation. By setting Fresnel ripples in the light-diffusing layer 50, the incident light can be evenly dispersed to the photosensitive area of ​​the light sensor 40, reducing uneven light distribution and local hot spots, and improving the acquisition accuracy of the light sensor 40.

[0089] Setting Fresnel patterns in the light-diffusing layer 50 can also reduce glare and ghosting. Strong direct light may cause glare in the light-transmitting area 30, thus affecting the normal operation of the light sensor 40.

[0090] The light reflects multiple times between the light-transmitting area 30 and the light sensor 40, which may produce ghosting and affect the accuracy of the data acquisition.

[0091] By setting a Fresnel pattern in the light-diffusing layer 50, glare and ghosting can be reduced, and the anti-interference capability of the light sensor 40 can be improved.

[0092] Fresnel patterns can be directly injection molded onto the light homogenizing layer 50, achieving high-precision manufacturing. Alternatively, Fresnel patterns can be imprinted onto the light homogenizing layer 50 at high temperatures using an imprinting mold, forming a uniform optical structure.

[0093] A laser engraving machine can also be used to engrave Fresnel patterns on the homogenization layer 50 to achieve a high-precision optical structure.

[0094] After Fresnel patterns are formed in the homogenization layer 50, the light distribution can be effectively homogenized, reducing uneven light distribution and local hot spots, and improving the acquisition accuracy of the light sensor 40.

[0095] In some embodiments, the cross-sectional shape of the hole structure on the first surface 211 or the second surface 212 is at least one of a circle, a square, a triangle, and an ellipse.

[0096] Understandably, the smooth edges of a circular aperture reduce light reflection and scattering at the edges, resulting in more even light distribution. Circular apertures are suitable for most smartphone camera modules, providing good light uniformity and aesthetics. They are also suitable for tablet camera modules, ensuring even light distribution.

[0097] Square apertures can be arranged more closely, saving space and making them suitable for space-constrained equipment. Square apertures are ideal for professional photographic equipment that requires high precision and a compact design.

[0098] A triangular aperture can guide light in a specific direction, making it suitable for applications requiring directional light collection. Triangular apertures are suitable for specialized lighting equipment that requires directional light collection. They can also be used in professional photographic equipment that demands a specific light distribution.

[0099] An elliptical aperture can guide light along its long axis, making it suitable for applications requiring light to be collected from a specific direction.

[0100] The smooth edges of an oval aperture reduce light reflection and scattering at the edges, resulting in more even light distribution. Oval apertures are suitable for professional photography equipment that requires light to be collected from specific directions. They are also suitable for high-end smartphones.

[0101] The aperture structure can also be a combination of various shapes. By combining apertures of different shapes, the advantages of different aperture shapes can be combined to optimize the transmission efficiency and distribution uniformity of light.

[0102] In some embodiments, see Figure 1 and 2 As shown, this disclosure proposes an electronic device, including a housing 60 and a camera module. The camera module further includes: a lens assembly 70, a shelf 20, a flash 10, a light-transmitting area 30, and a light sensor 40.

[0103] Lens assembly 70 is mounted on housing 60;

[0104] The shelf 20 is disposed in the area between the lens assembly 70 and the outer surface of the electronic device circuit board;

[0105] Flash 10 is mounted on shelf 20;

[0106] The light-transmitting area 30 is set on the shelf 20 and is adjacent to the flash lamp 10, and is used to transmit ambient light;

[0107] The light sensor 40 is located on the side of the shelf 20 away from the housing 60, in the area opposite to the light-transmitting area 30, and is used to collect ambient light.

[0108] Understandably, electronic devices can include smartphones, tablets, laptops, smartwatches, professional photography equipment, security monitoring equipment, vehicle cameras, etc.

[0109] The housing 60 is the outer shell of the electronic device, used to protect internal components and provide structural support. The housing 60 can be made of metal, plastic or composite material.

[0110] The camera module's lens assembly 70 can be located on the front or back of the device. The lens assembly 70 is responsible for capturing images and includes optical elements such as lenses, lens elements, and apertures. The lens assembly 70 can be a single-lens, dual-lens, or multi-lens configuration.

[0111] The shelf 20 is used to mount the flash 10 and the light sensor 40 and provides the necessary electrical connections. The shelf 20 can be a rigid circuit board (such as an FR-4 PCB board) or a flexible circuit board (such as an FPC).

[0112] The flash 10 is mounted on the shelf 20, typically close to the lens assembly 70, to provide an auxiliary light source in low-light conditions.

[0113] A light-transmitting area 30 is disposed on the shelf 20, adjacent to the flash lamp 10, for transmitting ambient light. The light-transmitting area 30 allows ambient light to pass through, ensuring that the light sensor 40 can receive sufficient ambient light information. The light-transmitting area 30 can employ a perforated structure, with the cross-sectional shape of the perforation being at least one of circular, square, triangular, and elliptical shapes to optimize light transmission efficiency and uniform distribution. The light-transmitting area 30 can also be made of transparent materials, such as transparent resin, transparent film, or transparent glass, to achieve efficient light transmission.

[0114] The light sensor 40 is used to collect ambient light intensity information and convert it into an electrical signal, which is used to adjust camera parameters such as exposure and white balance to optimize the photo effect.

[0115] The light sensor 40 can be a photodiode, a phototransistor, or a digital light sensor. The light sensor 40 is electrically connected to the circuit board to ensure that the electrical signal can be efficiently transmitted to the processing unit.
