Abstract
Description
Technical Field
[0001] This application relates to the field of end products, and in particular to a sensor module and electronic device. Background Technology
[0002] Ambient light sensors are a crucial electronic component in smart terminal devices. They detect the intensity of ambient light, allowing smart terminal products to adjust the brightness of their displays accordingly. However, current technologies often fail to effectively detect lateral light, particularly strong lateral light, leading to delays in timely adjustments to display brightness. Summary of the Invention
[0003] This application provides a sensor module and an electronic device to solve the problem in the related art where the photosensitive element does not clearly sense lateral light, resulting in untimely adjustment of the display screen brightness.
[0004] In a first aspect, this application provides a sensor module for use in electronic devices, the sensor module comprising:
[0005] A photosensitive element having a light-incident surface; and
[0006] A light-blocking element is movably disposed on at least one side of the photosensitive element and may intersect with the light-incident surface to block part of the incident light from entering the photosensitive element.
[0007] Secondly, this application also provides an electronic device, including a housing and a sensor module as described above, wherein the sensor module is disposed within the housing.
[0008] In this embodiment of the sensor module, when there is strong side light illumination, the light-blocking component of the sensor module can first move to the incident path of the strong side light. The light-blocking component can block the side light from illuminating the photosensitive element. At this time, the photosensitive element obtains the current ambient light intensity value. Then, the light-blocking component can move back to its original position, that is, the light-blocking component moves back to one side of the photosensitive element. At this time, the light-blocking component will not block the side light, and the side light can illuminate the photosensitive element. The photosensitive element obtains the current ambient light intensity value. By comparing the two light intensity values, it can be determined whether the electronic device is illuminated by side light, thereby improving the sensor module's ability to sense side light. When the sensor module is applied to an electronic device, the electronic device can sense changes in ambient light in a timely manner through the sensor module, enabling the electronic device to adjust the display brightness of the screen in a timely manner.

A mobile phone is an electronic device equipped with a cellular communication module.
[0027] For example, the electronic device provided in this application embodiment can be a mobile terminal device such as a mobile phone or tablet computer, or a device with display function such as an in-vehicle computer, laptop computer, data storage device, video playback device, or wearable device. To better understand the solution of this application, a mobile phone will be used as an example for explanation below.
[0028] Please refer to Figure 1 , Figure 1This is a schematic diagram of the front and back of an electronic device provided in an embodiment of this application. The electronic device 10 includes a housing 100, a display screen 200, a motherboard 300, and a camera 400.
[0029] The display screen 200 is disposed on the housing 100 to form the display surface 101 of the electronic device 10, and is used to display images, text and other information. The display screen 200 may be a liquid crystal display (LCD) or an organic light-emitting diode (OLED) display screen.
[0030] The housing 100 forms the external outline of the electronic device 10 to accommodate the electronic components and functional parts of the electronic device 10, while also providing a seal and protection for the internal electronic components and functional parts of the electronic device 10. For example, the battery, motherboard 300, sensors, and other electronic components and functional parts of the electronic device 10 can be housed inside the housing 100. It is understood that the housing 100 may include a mid-frame 110 and a back cover 120.
[0031] The middle frame 110 can be a plate-like (or sheet-like) structure or a hollow frame structure. The middle frame 110 provides support for the electronic devices or functional components in the electronic device 10, allowing them to be mounted together. For example, the middle frame 110 may have grooves, protrusions, or other structures to facilitate the mounting of the electronic devices or functional components. It is understood that the material of the middle frame 110 may include metal or plastic.
[0032] The back cover 120, together with the mid-frame 110 and the display screen 200, seals the electronic components and functional parts of the electronic device 10 inside the electronic device 10, thereby protecting the electronic components and functional parts of the electronic device 10. Understandably, the material of the back cover 120 may also include metal or plastic.
[0033] The motherboard 300 is located inside the housing 100. For example, the motherboard 300 can be mounted on the mid-frame 110 of the housing 100 for fixation, and sealed inside the electronic device 10 by the rear cover 120. The motherboard 300 may integrate one or more functional components such as a processor, headphone jack, accelerometer, gyroscope, and motor. Simultaneously, the display screen 200 can be electrically connected to the motherboard 300 to control the display of the screen via the processor on the motherboard 300.
[0034] The camera 400 is used for taking photos and videos, enabling the electronic device 10 to perform its shooting function. The camera 400 may include a front-facing camera and a rear-facing camera. The light-receiving side of the front-facing camera is located on the side of the display screen 200 away from the back cover 120, and it can be used for selfies, videos, facial recognition, etc. The light-receiving side of the rear-facing camera is located on the side of the back cover 120 away from the display screen 200, and it can be used for taking photos and videos.
[0035] The display brightness of the screen 200 is a crucial factor affecting the user experience. In bright ambient light, the screen 200 needs to be bright to ensure users can clearly see the displayed content; conversely, in dim ambient light, the brightness needs to be adjusted to avoid eye strain from excessive brightness. To facilitate brightness adjustment, the electronic device 10 also includes a sensor module 500. This module detects the ambient light intensity and automatically adjusts the screen brightness accordingly, ensuring a comfortable viewing experience for the user.
[0036] Furthermore, the power consumed by the display screen 200 accounts for a large proportion of the total battery power of the electronic device 10. The electronic device 10 can automatically adjust the display brightness of the display screen 200 based on the ambient light intensity detected by the sensor module 500, which can reduce the power consumption of the display screen 200.
[0037] Please refer to Figure 2 , Figure 2 This is a first structural schematic diagram of a sensor module provided in an embodiment of this application applied to an electronic device from a first viewing angle. The sensor module 500 includes a photosensitive element 510.
[0038] The photosensitive element 510 can be an ambient light sensor composed of photosensitive devices. After being irradiated by visible light, the photosensitive element 510 generates a photoelectric effect, converting the light signal into an electrical signal output. When the ambient light changes, the light signal received by the photosensitive element 510 changes, thereby generating different electrical signal outputs.
[0039] The photosensitive element 510 has a light-incident surface 511. It can be understood that the light-incident surface 511 is the side of the photosensitive element 510 used to receive light.
[0040] Specifically, the photosensitive element 510 is used to receive a first incident light and a second incident light. The first incident light is a light that is perpendicular to the light-incident surface 511, and the second incident light is a light that is inclined to the light-incident surface 511. The first incident light is perpendicular to the light-incident surface 511, that is, the first incident light is frontal light, and the second incident light is inclined to the light-incident surface 511, that is, the second incident light is lateral light.
[0041] In related technologies, ambient light sensors in electronic devices typically face the display screen directly. These sensors are not very sensitive to side light, causing the electronic device to be unable to adjust the display screen brightness in a timely manner. To address this issue, the sensor module 500 provided in this application embodiment further includes a light-blocking element 520.
[0042] Please continue to refer to this. Figure 2 The light-blocking member 520 is movably disposed on at least one side of the photosensitive element 510 and may intersect with the light-incident surface 511 to block part of the incident light from entering the photosensitive element 510. It should be noted that the light-blocking member 520 intersecting with the light-incident surface 511 means that the plane where the light-blocking member 520 is located intersects with the plane where the light-incident surface 511 is located.
[0043] For example, the light-blocking member 520 can be moved to be located on the incident path of a portion of the second incident light, that is, the light-blocking member 520 can be moved to be on the incident path of a portion of the side light, so as to block the side light from illuminating the photosensitive element 510.
[0044] Specifically, in the electronic device 10 using the sensor module 500 of this application embodiment, when there is strong side light illumination, the light-blocking member 520 of the sensor module 500 can first move to the incident path of the strong side light. The light-blocking member 520 can block the side light from illuminating the photosensitive element 510. At this time, the photosensitive element 510 obtains the current ambient light intensity value. Then, the light-blocking member 520 can move back to its original position, that is, the light-blocking member 520 moves back to one side of the photosensitive element 510. At this time, the light-blocking member 520 will not block the side light, and the side light can illuminate the photosensitive element 510. The photosensitive element 510 obtains the current ambient light intensity value. By comparing the two light intensity values, it can be determined whether the electronic device 10 is illuminated by side light, thereby improving the sensor module 500's ability to sense side light, so as to be able to sense changes in ambient light in a timely manner, so that the electronic device 10 can adjust the brightness of the display screen 200 in a timely manner.
[0045] Understandably, the light-blocking component 520 can be made of opaque material to block incident light.
[0046] Optionally, in some embodiments, the light-blocking element 520 can be made of any material, and the light-blocking effect can be achieved by coating the surface of the light-blocking element 520 with a light-blocking coating.
[0047] Understandably, the sensor module 500 can be positioned between the display screen 200 and the back cover 120. The display screen 200 and / or the back cover 120 can be provided with a light-transmitting area. The sensor module 500 is positioned opposite to the light-transmitting area, so that ambient light can pass through the light-transmitting area and illuminate the photosensitive element 510 of the sensor module 500.
[0048] The photosensitive element 510 is mounted on the motherboard 300 and electrically connected to the motherboard 300. The motherboard 300 is also equipped with a processor. The processor can control the photosensitive element 510 to detect the light intensity of the external environment. The photosensitive element 510 can send the light brightness it detects to the processor so that the processor can control the display screen 200 to adjust the display brightness.
[0049] The photosensitive element 510 is generally rectangular and includes a first side 512, a third side 514, a second side 513, and a fourth side 515 connected in sequence. The first side 512 and the second side 513 are arranged opposite each other along a second direction, and the third side 514 and the fourth side 515 are arranged opposite each other along a third direction. The second direction and the third direction are perpendicular to each other.
[0050] For example, in one embodiment, please refer to the reference Figure 2 and Figure 3 , Figure 3 This is a first structural schematic diagram of a sensor module provided in this application, applied to an electronic device from a second perspective. The light-blocking member 520 includes a first light-blocking member 521 and a second light-blocking member 522. The first light-blocking member 521 is movably disposed on a first side 512 and can move along a first direction to block incident light from the first side 512. The second light-blocking member 522 is movably disposed on a second side 513 and can move along the first direction to block incident light from the second side 513.
[0051] The first direction is perpendicular to the light-incident surface 511, that is, the first direction is parallel to the thickness direction of the photosensitive element 510. The first light-blocking element 521 and the second light-blocking element 522 can both move along the first direction, that is, the first light-blocking element 521 and the second light-blocking element 522 can both move along the thickness direction of the photosensitive element 510.
[0052] The sensor module 500 may further include a first driving structure (not shown) and a second driving structure (not shown). The first driving structure is connected to the first light-blocking element 521 to drive the first light-blocking element 521 to move. The second driving structure is connected to the second light-blocking element 522 to drive the second light-blocking element 522 to move. The driving structure may be a micro-motor.
[0053] A first light-blocking element 521 is disposed on the first side 512, and a second light-blocking element 522 is disposed on the second side 513. That is, the first light-blocking element 521 and the second light-blocking element 522 are respectively disposed on opposite sides of the photosensitive element 510, thereby blocking incident light from opposite directions on the photosensitive element 510. The first light-blocking element 521 and the second light-blocking element 522 can be disposed opposite each other. Furthermore, the first light-blocking element 521 and the second light-blocking element 522 can be disposed directly opposite each other.
[0054] It should be noted that when the electronic device 10 is not performing ambient light detection, the first light blocking element 521 and the second light blocking element 522 are in their initial positions. At this time, the first light blocking element 521 is entirely located on one side of the plane where the light incident surface 511 is located, and the second light blocking element 522 is entirely located on one side of the plane where the light incident surface 511 is located, to prevent the incident light from being blocked.
[0055] Specifically, by providing a first light-blocking element 521 and a second light-blocking element 522 on opposite sides of the photosensitive element 510, during the process of the electronic device 10 detecting the light intensity of the external environment, the first light-blocking element 521 is controlled to move along a first direction, causing most of the first light-blocking element 521 to extend beyond the plane of the light-incident surface 511. This places the first light-blocking element 521 on the incident path of the second incident light beam incident from the first side 512 direction, thus blocking the incident light beam from the first side and preventing lateral illumination from the first side 512 direction. When light is incident on the photosensitive element 510, the photosensitive element 510 can acquire the light intensity values of the ambient light on one side of the light-incident surface 511 and the second side 513. Then, by controlling the first light-blocking element 521 to move back to its initial position, the first light-blocking element 521 will not block the second incident light from the direction of the first side 512, allowing the lateral light incident from the direction of the first side 512 to illuminate the photosensitive element 510. At this time, the photosensitive element 510 can acquire the light intensity values of the ambient light on one side of the light-incident surface 511, the first side 512, and the second side 513. If there is a large difference between the light intensity value detected by the photosensitive element 510 in the first detection and the light intensity value detected in the second detection, for example, if the light intensity value detected by the photosensitive element 510 in the first detection is significantly less than the light intensity value detected in the second detection, it can be determined that there is strong lateral light in the direction of the first side 512 of the photosensitive element 510, and the electronic device 10 can adjust the brightness of the display screen 200 accordingly.
[0056] Similarly, during the process of the electronic device 10 detecting the light intensity of the external environment, by controlling the second light-blocking element 522 to move along the first direction, most of the second light-blocking element 522 extends beyond the plane where the light-incident surface 511 is located, thereby placing the second light-blocking element 522 on the incident path of the second incident light beam incident from the second side 513 direction, blocking the incident light beam from the second side, and preventing the lateral light incident from the second side 513 direction from illuminating the photosensitive element 510. At this time, the photosensitive element 510 can obtain the light intensity values of the ambient light on one side of the light-incident surface 511 and the first side 512. Then, by controlling the second light-blocking element 522 to move back to the initial position, the second light-blocking element 522 will not block the second incident light beam incident from the second side 513 direction, allowing the lateral light incident from the second side 513 direction to illuminate the photosensitive element 510. At this time, the photosensitive element 510 can obtain the light intensity values of the ambient light on one side of the light-incident surface 511, the first side 512, and the second side 513. If there is a large difference between the light intensity value detected by the photosensitive element 510 in the first detection and the light intensity value detected in the second detection, for example, if the light intensity value detected by the photosensitive element 510 in the first detection is significantly less than the light intensity value detected in the second detection, it can be determined that there is strong lateral light in the direction of the second side 513 of the photosensitive element 510, and then the electronic device 10 can adjust the brightness of the display screen 200 accordingly.
[0057] When it is determined that there is strong lateral light on one side of the photosensitive element 510, the electronic device 10 can control the display screen 200 to increase the display brightness.
[0058] Optionally, in some alternative embodiments, when it is determined that there is strong lateral light on one side of the photosensitive element 510, the electronic device 10 can also adjust the display brightness of the display screen 200 to display in a gradient. The display brightness of the display screen 200 can decrease or increase linearly from one side to the other, that is, the brightness of different parts of the display screen 200 can be adjusted to be different. The brightness of the side of the display screen 200 closer to the strong lateral light can be adjusted to be relatively brighter, while the display brightness of the side of the display screen 200 away from the strong lateral light can be adjusted to be relatively darker.
[0059] For example, please refer to Figure 3 The electronic device 10 includes a first sidewall 111 and a second sidewall 112 that are opposite each other along a second direction, which is perpendicular to the first direction. A photosensitive element 510 is disposed between the first sidewall 111 and the second sidewall 112, and the first sidewall 512 and the second sidewall 513 of the photosensitive element 510 are disposed opposite each other along the second direction.
[0060] Specifically, the first sidewall 111 and the second sidewall 112 can be sidewalls formed on the middle frame 110. The middle frame 110 can be rectangular and can include multiple sidewalls. The first sidewall 111 and the second sidewall 112 can be the two longer sidewalls among all the sidewalls of the middle frame 110. The first sidewall 111 and the second sidewall 112 extend along the length direction of the middle frame 110 and are arranged opposite to each other along the width direction of the middle frame 110, that is, the second direction is the width direction of the middle frame 110.
[0061] A photosensitive element 510 is disposed between the first sidewall 111 and the second sidewall 112, and the first side 512 and the second side 513 of the photosensitive element 510 are arranged opposite each other along a second direction. That is, the first side 512 and the second side 513 of the photosensitive element 510 are arranged opposite each other along the width direction of the middle frame 110, with the first side 512 facing one of the first sidewall 111 and the second sidewall 112, and the second side 513 facing the other of the first sidewall 111 and the second sidewall 112. Therefore, the incident light illuminating the photosensitive element 510 from the direction of the first side 512 and the second side 513 is lateral light illuminating along the width direction of the electronic device 10.
[0062] Therefore, when it is determined that there is strong lateral light on the first side 512 or the second side 513 of the photosensitive element 510, that is, strong lateral light exists on one side of the electronic device 10 along its width direction, the electronic device 10 can adjust the display brightness of the display screen 200 to display in a gradient along the width direction of the electronic device 10. For example, the electronic device 10 can adjust the display brightness of the display screen 200 to decrease or increase from the first sidewall 111 to the second sidewall 112. Figure 3 As shown in the example, the electronic device 10 can adjust the display brightness of the display screen 200 from right to left, decreasing or increasing it.
[0063] For example, please refer to the reference. Figure 4 and Figure 5 , Figure 4 This is a schematic diagram of the sensor module in the first working mode according to an embodiment of this application. Figure 5 This is a schematic diagram of the second state of the sensor module in the second operating mode according to an embodiment of this application. The sensor module 500 includes a first operating mode. When the sensor module 500 is in the first operating mode, the first light-blocking element 521 moves to block the incident light from the first side 512 so that the photosensitive element 510 acquires a first light intensity value. After that, the first light-blocking element 521 moves to its initial position, and the second light-blocking element 522 moves to block the incident light from the second side 513 so that the photosensitive element 510 acquires a second light intensity value. The electronic device 10 is used to adjust the display brightness of the display screen 200 according to the first light intensity value and the second light intensity value.
[0064] Please refer to Figure 6 and Figure 7 , Figure 6 for Figure 4 A magnified view of a portion of point A in the middle. Figure 7 for Figure 5 A magnified view of a portion at point B. Specifically, the first light-blocking element 521 moves to block the incident light from the first side 512, preventing lateral light incident from the direction of the first side 512 from reaching the photosensitive element 510, as shown below. Figure 6 As shown, at this time, the photosensitive element 510 can receive incident light from directions other than the direction of the first side 512. Therefore, the first light intensity value detected by the photosensitive element 510 at this time is the ambient light intensity excluding the incident light from the first side 512. Then, the first light-blocking element 521 moves to its initial position, and the second light-blocking element 522 moves to block the incident light from the second side 513, preventing lateral light incident from the direction of the second side 513 from reaching the photosensitive element 510. Figure 7 As shown, at this time, the photosensitive element 510 can receive incident light from directions other than the direction of the second side 513. Therefore, the second light intensity value detected by the photosensitive element 510 at this time is the ambient light intensity excluding the incident light from the second side 513. Specifically, when both detections are under the same lighting conditions, if one of the first side 512 and the second side 513 is illuminated by strong light, the specific values of the first light intensity value and the second light intensity value will have a large difference; conversely, the specific values of the first light intensity value and the second light intensity value will not differ significantly.
[0065] Therefore, by comparing the first light intensity value and the second light intensity value, the light intensity of the light from the first side 512 and the light from the second side 513 can be determined, thereby enabling the electronic device 10 to adjust the display brightness of the display screen 200 according to the light intensity. Thus, through the aforementioned sequential movement control of the first light-blocking element 521 and the second light-blocking element 522, the photosensitive element 510 only needs to perform two detections of the ambient light, eliminating the need for an additional detection when both the first light-blocking element 521 and the second light-blocking element 522 are in their initial positions. This reduces the number of detections by the photosensitive element 510, simplifies the judgment process, and allows the electronic device 10 to adjust the display brightness of the display screen 200 in a timely manner.
[0066] For example, if the difference between the first light intensity value and the second light intensity value is greater than the preset light intensity value, the electronic device 10 is used to adjust the display brightness of the display screen 200 in a gradient transition according to the first light intensity value and the second light intensity value.
[0067] It should be noted that the difference here is the absolute value of the difference between the first light intensity value and the second light intensity value; that is, the difference between the first light intensity value and the second light intensity value is a positive value. It should also be noted that the preset light intensity value is stored in advance in the control algorithm of the electronic device 10. The preset light intensity value can be a single value or a range of values.
[0068] For example, taking the first side 512 of the photosensitive element 510 facing the first sidewall 111 and the second side 513 facing the second sidewall 112 as an example, when the first light intensity value is greater than the second light intensity value, since the first light intensity value is the ambient light intensity after removing the incident light from the first side 512, and the second light intensity value is the ambient light intensity after removing the incident light from the second side 513, it means that the light intensity of the incident light from the second side 513 is significantly stronger than the light intensity of the incident light from the first side 512. That is, the light intensity on the second sidewall 112 side of the electronic device 10 is stronger than the light intensity on the first sidewall 111 side. At this time, the electronic device 10 can adjust the display brightness of the area of the display screen 200 near the second sidewall 112 to the first brightness based on the first light intensity value, and adjust the display brightness of the display area of the display screen 200 near the first sidewall 111 to the second brightness based on the second light intensity value (the second brightness is less than the first brightness). The display area in the middle of the display screen 200 adjusts its display brightness from the second sidewall 112 toward the first sidewall 111, linearly decreasing from the first brightness to the second brightness, so that the display brightness of the display screen 200 of the electronic device 10 near the side facing strong light is relatively brighter.
[0069] Thus, the electronic device 10 of this application embodiment, by providing light-blocking members 520 on both sides of the photosensitive element 510, can block or not block side light by moving the light-blocking members 520 along the first direction. By detecting the ambient light intensity of the blocked and unblocked side light by the photosensitive element 510, it can be determined whether there is strong side light irradiation on the electronic device 10. Therefore, the electronic device 10 can adjust the display brightness of the display screen 200 in a gradient display according to which side has strong side light, so that the brightness of each part of the display screen 200 is adapted to the ambient light in each part, which is beneficial to the user's eyesight, makes the user more comfortable to watch the display screen 200, and improves the user experience.
[0070] Optionally, if the difference between the first light intensity value and the second light intensity value is less than or equal to the preset light intensity value, the electronic device 10 is used to adjust the display brightness of the display screen 200 to a third brightness according to the first light intensity value or the second light intensity value.
[0071] When the difference between the first light intensity value and the second light intensity value is less than or equal to the preset light intensity value, it means that the light intensity of the incident light on the first side 512 is almost the same as the light intensity of the incident light on the second side 513. The electronic device 10 can adjust the display brightness of the display screen 200 according to either the first light intensity value or the second light intensity value, so that the display brightness is the same at all parts of the display screen 200.
[0072] Generally, the main function of the sensor module 500 is to detect ambient light intensity so that the electronic device 10 can automatically adjust the display brightness of the screen 200 according to the ambient light intensity. However, in some cases, the ambient light intensity detected by the sensor module 500 can also be used as a brightness adjustment parameter for the camera 400 to assist the camera 400 in imaging.
[0073] For example, when a user takes a photo using the camera 400, they often focus on a specific area of the shooting interface to make the image of that area clearer. When the area to be focused on is at the edge of the shooting interface, the angle between the incident light reflected from that area to the camera 400 and the optical axis of the camera 400 lens is relatively large. In other words, the incident light reflected from that area is side light with a large angle of incidence, which often results in insufficient brightness and affects the image quality. In this case, the sensor module 500 of this embodiment can detect the brightness of the ambient light in the focused area and use it as a brightness adjustment parameter when the image processor of the camera 400 performs image processing to compensate for the image brightness.
[0074] For example, in one embodiment, please refer to Figure 8 , Figure 8 This is a schematic diagram of the sensor module in a second operating mode according to an embodiment of this application. The sensor module 500 includes a second operating mode. When the sensor module 500 is in the second operating mode, the first light-blocking element 521 moves a first distance along a first direction, while the second light-blocking element 522 moves a second distance along the first direction. The first light-blocking element 521 and the second light-blocking element 522 together form a first detection angle, so that the photosensitive element 510 acquires a third light intensity value of the incident light within the range of the first detection angle. The electronic device 10 is used to adjust the imaging brightness of the camera 400 according to the third light intensity value.
[0075] The second working mode of the sensor module 500 is applied to the photography scenario of the electronic device 10. When the user takes a picture using the electronic device 10, the processor of the electronic device 10 can control the sensor module 500 to switch to the second working mode.
[0076] Specifically, please refer to Figure 9 and Figure 10 , Figure 9 for Figure 8 A magnified view of a section at point C. Figure 10This is a schematic diagram illustrating the application of the sensor module of this application in a shooting scenario of an electronic device. During the shooting process of the electronic device 10, when the user focuses on a certain position on the shooting interface, the electronic device 10 sends the position coordinates of the focus area to the processor. The processor calculates and converts the position coordinates of the focus area into the incident angle of the light reflected from the focus area received by the photosensitive element 510, and calculates and converts it into the motion parameters of the first light blocking element 521 and the second light blocking element 522. Then, it controls the first light blocking element 521 to move a first distance along the first direction, and simultaneously controls the second light blocking element 522 to move a second distance along the first direction, so that the first light blocking element 521 and the second light blocking element 522 enclose a first detection angle. The angle range of the first detection angle needs to be approximately the same as the incident angle range of the light reflected from the focus area, so that the photosensitive element 510 mainly receives the incident light reflected from the focus area, thereby detecting a third light intensity value (i.e., the light brightness of the focus area). Then, the electronic device 10 uses the third light intensity value as the brightness adjustment parameter for the camera 400 and adjusts the brightness of the captured image according to the shooting algorithm built into the electronic device 10.
[0077] Optionally, in some alternative embodiments, the second operating mode of the photosensitive element 510 can not only detect the light intensity of the focus area, but also be used to detect the maximum brightness of the shooting interface.
[0078] For example, during the shooting process of the electronic device 10, the image processor of the camera 400 of the electronic device 10 can detect the point of maximum brightness on the shooting interface. The processor sends the position coordinates of the point of maximum brightness to the image sensor 510, which calculates and converts the position coordinates of the point of maximum brightness into the incident angle of the light reflected from the point of maximum brightness. The image sensor 510 then calculates and converts the angles of the light reflected from the point of maximum brightness into motion parameters of the first light blocking element 521 and the second light blocking element 522. The first light blocking element 521 is then controlled to move a first distance along a first direction, while the second light blocking element 522 is controlled to move a second distance along the first direction. This causes the first light blocking element 521 and the second light blocking element 522 to form a first detection angle. The range of the first detection angle must be approximately the same as the range of the incident angle of the light reflected from the point of maximum brightness. This ensures that the image sensor 510 mainly receives the incident light reflected from the point of maximum brightness, thereby detecting a third light intensity value (i.e., the brightness of the light at the point of maximum brightness). The electronic device 10 then uses the third light intensity value as the brightness adjustment parameter for the camera 400 and adjusts the brightness of the captured image according to the shooting algorithm built into the electronic device 10.
[0079] Optionally, in other embodiments, during the shooting process of the electronic device 10, the photosensitive element 510 can obtain a third light intensity value by detecting the light intensity of the focus area through the second working mode, and can also obtain another third light intensity value by detecting the maximum brightness of the shooting interface through the second working mode. The electronic device 10 can use the two different third light intensity values obtained from the two detections as the brightness adjustment parameters of the camera 400, and adjust the brightness of the captured image according to the shooting algorithm built into the electronic device 10, thereby further improving the imaging effect.
[0080] Optionally, in some other embodiments, during the shooting process of the electronic device 10, the photosensitive element 510 can also directly detect the overall light intensity of the external environment, and at the same time, it can also detect the light intensity of the focus area and the maximum brightness of the shooting interface through the second working mode, thereby obtaining three different light intensity values. The electronic device 10 can use the three light intensity values obtained from the three detections as the brightness adjustment parameters of the camera 400, and adjust the brightness of the captured image according to the shooting algorithm built into the electronic device 10, thereby further improving the imaging effect.
[0081] Optional, please refer to Figure 11 , Figure 11 This is a second structural schematic diagram of the sensor module provided in this application embodiment applied to an electronic device from a second perspective. The light-blocking member 520 further includes a third light-blocking member 523 and a fourth light-blocking member 524. The third light-blocking member 523 is movably disposed on the third side 514 and can move along a first direction to block the incident light from the third side 514. The fourth light-blocking member 524 is movably disposed on the fourth side 515 and can move along the first direction to block the incident light from the fourth side 515.
[0082] The first side 512, the third side 514, the second side 513, and the fourth side 515 of the photosensitive element 510 are connected in sequence. The third side 514 and the fourth side 515 are located between the first side 512 and the second side 513. That is to say, the third side 514 and the fourth side 515 of the photosensitive element 510 are arranged opposite each other along the length direction of the middle frame 110. Therefore, the incident light that shines on the photosensitive element 510 from the direction of the third side 514 and the fourth side 515 is lateral light that shines along the length direction of the electronic device 10.
[0083] The middle frame 110 may further include a third sidewall 113 and a fourth sidewall 114, which extend along the width direction of the middle frame 110 and are disposed opposite to each other along the length direction of the middle frame 110. A photosensitive element 510 is disposed between the third sidewall 113 and the fourth sidewall 114, with the third sidewall 514 of the photosensitive element 510 facing one of the third sidewall 113 and the fourth sidewall 114, and the fourth sidewall 515 of the photosensitive element 510 facing the other of the third sidewall 113 and the fourth sidewall 114.
[0084] When it is determined that there is strong lateral light on the third side 514 or the fourth side 515 of the photosensitive element 510, that is, strong lateral light exists on one side of the electronic device 10 along its length, the electronic device 10 can adjust the display brightness of the display screen 200 to display in a gradient along the length of the electronic device 10. For example, the electronic device 10 can adjust the display brightness of the display screen 200 to decrease or increase from the third sidewall 113 to the fourth sidewall 114. Figure 11 As shown in the example, the electronic device 10 can adjust the display brightness of the display screen 200 from top to bottom, decreasing or increasing it.
[0085] Understandably, when the sensor module 500 also includes a third light-blocking element 523 and a fourth light-blocking element 524, the ambient light intensity detected by it can also be used as a brightness adjustment parameter of the camera 400 to assist the camera 400 in imaging.
[0086] For example, the sensor module 500 may further include a third operating mode. When the sensor module 500 is in the third operating mode, the first light-blocking element 521 moves a first distance along a first direction, the second light-blocking element 522 moves a second distance along the first direction, the third light-blocking element 523 moves a third distance along the first direction, and the fourth light-blocking element 524 moves a fourth distance along the first direction. The first light-blocking element 521, the second light-blocking element 522, the third light-blocking element 523, and the fourth light-blocking element 524 together form a second detection angle, so that the photosensitive element 510 acquires a fourth light intensity value of the incident light within the range of the second detection angle. The electronic device 10 is used to adjust the imaging brightness of the camera 400 according to the third light intensity value.
[0087] For example, during the shooting process of electronic device 10, when the user focuses on a certain position on the shooting interface, electronic device 10 sends the position coordinates of the focus area to the processor. The processor calculates and converts the position coordinates of the focus area into the incident angle of the light reflected from the focus area received by the photosensitive element 510, and calculates and converts them into motion parameters of the first light blocking element 521, the second light blocking element 522, the third light blocking element 523, and the fourth light blocking element 524. This allows the processor to control the first light blocking element 521 to move a first distance along a first direction, simultaneously control the second light blocking element 522 to move a second distance along the first direction, and control the third light blocking element 523 to move a third distance along the first direction. The fourth light-blocking element 524 is controlled to move a fourth distance along the first direction, so that the first light-blocking element 521, the second light-blocking element 522, the third light-blocking element 523 and the fourth light-blocking element 524 surround and form a second detection angle. The range of the second detection angle should be approximately the same as the range of the incident angle of the light reflected from the focus area, so that the photosensitive element 510 mainly receives the incident light reflected from the focus area, thereby detecting the fourth light intensity value (i.e., the light brightness of the focus point). Then, the electronic device 10 uses the fourth light intensity value as the brightness adjustment parameter for the camera 400 to capture the image, and adjusts the brightness of the captured image according to the shooting algorithm built into the electronic device 10.
[0088] For example, during the shooting process of electronic device 10, the image processor of camera 400 of electronic device 10 can detect the point of maximum brightness on the shooting interface. The processor sends the position coordinates of the point of maximum brightness to the image sensor 510. The image sensor 510 calculates and converts the position coordinates of the point of maximum brightness into the incident angle of the light reflected from the point of maximum brightness. The image sensor 510 then calculates and converts these into motion parameters for the first light blocking element 521, the second light blocking element 522, the third light blocking element 523, and the fourth light blocking element 524. This allows the image sensor 521 to move a first distance along a first direction, the second light blocking element 522 to move a second distance along the first direction, and the third light blocking element 523 to move a third distance along the first direction. The third distance and the control of the fourth light-blocking element 524 to move a fourth distance along the first direction, so that the first light-blocking element 521, the second light-blocking element 522, the third light-blocking element 523 and the fourth light-blocking element 524 surround to form a second detection angle. The range of the second detection angle should be approximately the same as the range of the incident angle of the light reflected from the position of maximum brightness, so that the photosensitive element 510 mainly receives the incident light reflected from the position of maximum brightness, thereby detecting the fourth light intensity value (i.e. the light brightness of the maximum brightness point). Then, the electronic device 10 uses the fourth light intensity value as the brightness adjustment parameter for the camera 400 to capture the image, and adjusts the brightness of the captured image according to the shooting algorithm built into the electronic device 10.
[0089] Optionally, in other embodiments, during the shooting process of the electronic device 10, the photosensitive element 510 can obtain a fourth light intensity value by detecting the light intensity of the focus area through the third working mode, and can also obtain another fourth light intensity value by detecting the maximum brightness of the shooting interface through the third working mode. The electronic device 10 can use the two different fourth light intensity values obtained from the two detections as the brightness adjustment parameters of the camera 400, and adjust the brightness of the captured image according to the shooting algorithm built into the electronic device 10, thereby further improving the imaging effect.
[0090] Optionally, in some other embodiments, during the shooting process of the electronic device 10, the photosensitive element 510 can also directly detect the overall light intensity of the external environment, and at the same time, it can also detect the light intensity of the focus area and the maximum brightness of the shooting interface through the third working mode, thereby obtaining three different light intensity values. The electronic device 10 can use the three light intensity values obtained from the three detections as the brightness adjustment parameters of the camera 400, and adjust the brightness of the captured image according to the shooting algorithm built into the electronic device 10, thereby further improving the imaging effect.
[0091] The electronic device 10 has a display surface 101 and a non-display surface 102 that are opposite each other along its own thickness direction. The electronic device 10 includes a front-facing camera 410 and a rear-facing camera 420. The light-incident side of the front-facing camera 410 faces the display surface 101 and is away from the non-display surface 102. The light-incident side of the rear-facing camera 420 faces the non-display surface 102 and is away from the display surface 101.
[0092] The sensor module 500 can be configured to assist imaging of the front camera 410 or to assist imaging of the rear camera 420.
[0093] Optionally, in one embodiment, please refer to Figure 12 , Figure 12 This is a second structural schematic diagram of a sensor module provided in this application, applied to an electronic device from a first perspective. The sensor module 500 includes a first sensor module 500a and a second sensor module 500b. Both the first sensor module 500a and the second sensor module 500b can have the first operating mode, the second operating mode, and the third operating mode described in the above embodiments.
[0094] The first sensor module 500a is disposed between the display surface 101 and the non-display surface 102, and the light-incident surface 511 of the photosensitive element 510 of the first sensor module 500a faces the display surface 101, which is used to detect the light intensity on one side of the display surface 101, so that the electronic device 10 adjusts the imaging brightness of the front camera 410 according to the light intensity on one side of the display surface 101.
[0095] The display surface 101 is the side surface of the display screen 200 used for display, which is also the front of the electronic device 10. The display surface 101 (display screen 200) may be provided with a first light-transmitting area 210, which is opposite to the photosensitive element 510 of the first sensor module 500a.
[0096] Specifically, the front-facing camera 410 collects light incident from the front of the electronic device 10. By facing the light-incident surface 511 of the photosensitive element 510 of the first sensor module 500a toward the display surface 101, that is, by facing the front of the electronic device 10 with the photosensitive element 510 of the first sensor module 500a, the photosensitive element 510 of the first sensor module 500a can receive light incident from the front of the electronic device 10. Thus, the electronic device 10 can perform auxiliary imaging of the front-facing camera 410 based on the ambient light intensity detected by the first sensor module 500a in the second or third working mode, which can improve the selfie or video effect of the electronic device 10 and improve the front-facing camera imaging effect.
[0097] Understandably, the electronic device 10 is also used to adjust the display brightness of the display screen 200 based on the light intensity detected by the first sensor module 500a on one side of the display surface 101. For example, the electronic device 10 can adjust the display brightness of the display screen 200 to display in a gradient or adjust the display brightness of all parts of the display screen 200 to be the same based on the light intensity detected by the first sensor module 500a on one side of the display surface 101 in the first working mode.
[0098] The second sensor module 500b is disposed between the display surface 101 and the non-display surface 102, and the light-incident surface 511 of the photosensitive element 510 of the second sensor module 500b faces the non-display surface 102, for detecting the light intensity on the side of the non-display surface 102, so that the electronic device 10 adjusts the imaging brightness of the rear camera 420 according to the light intensity on the side of the non-display surface 102.
[0099] The non-display surface 102 is the side of the back cover 120 away from the display screen 200, that is, the back of the electronic device 10. The non-display surface 102 (back cover 120) may be provided with a second light-transmitting area 121, which is opposite to the photosensitive element 510 of the second sensor module 500b.
[0100] Specifically, the rear camera 420 collects light incident from the back of the electronic device 10. By facing the light-incident surface 511 of the photosensitive element 510 of the second sensor module 500b toward the non-display surface 102, that is, by facing the back of the electronic device 10, the photosensitive element 510 of the second sensor module 500b can receive light incident from the back of the electronic device 10. Thus, the electronic device 10 can perform auxiliary imaging of the rear camera 420 based on the ambient light intensity detected by the second sensor module 500b in the second or third working mode, thereby improving the rear camera imaging effect of the electronic device 10.
[0101] It should be noted that, in some optional embodiments, the light intensity detected by the second sensor module 500b on the non-display surface 102 side can also be used as a basis for adjusting the brightness of the display screen 200 of the electronic device 10. For example, the electronic device 10 can adjust the display brightness of the display screen 200 by combining the light intensity detected by the first sensor module 500a on the display surface 101 side and the light intensity detected by the second sensor module 500b on the non-display surface 102 side, thereby adapting the display brightness of the display screen 200 to the lighting environment of the front and back of the electronic device 10, making it more comfortable for the user to view the display screen 200, and further improving the user experience.

The descriptions of the embodiments above are only for the purpose of helping to understand this application. Furthermore, those skilled in the art will recognize that, based on the ideas of this application, there will be changes in the specific implementation methods and application scope.
