Description

Technical Field

[0001] This application relates to the field of display device technology, and in particular to a mobile smart screen camera detection system and detection method. Background Technology

[0002] Mobile smart screens, as intelligent terminals integrating display, interaction, and entertainment, are widely used in scenarios such as video calls, online office work, and gesture-based interaction, and are typically equipped with camera modules to meet image acquisition needs. However, while the camera configuration enhances functionality, it also brings about a conflict between privacy protection and ease of use.

[0003] In existing technologies, mobile smart screens employ two main approaches: one uses physical blocking to protect privacy, but this provides little to no direct feedback on the current status; the other uses software to provide status alerts, but this fails to accurately reflect the actual usage of the camera. The lack of effective coordination between these two solutions makes it difficult to accurately reflect the actual usability of the camera module, which can negatively impact user experience and privacy perception in practical use.

[0004] Therefore, existing technologies have defects and shortcomings, and need further improvement and development. Summary of the Invention

[0005] In view of the shortcomings of the prior art, the purpose of this application is to provide a mobile smart screen camera detection system and detection method, which aims to solve the problem that there is no effective linkage between physical obstruction of the mobile smart screen and software prompts in the prior art, making it difficult to accurately reflect the actual usability status of the camera module.

[0006] The technical solution adopted by this application to solve the technical problem is as follows: A mobile smart screen camera detection system, used for detecting mobile smart screen cameras, comprising: A physical baffle is movably disposed on the front side of the camera of the mobile smart screen to block or expose the camera; A detection switch is connected to the physical baffle. The detection switch is used to detect the open or closed state of the physical baffle and output a corresponding status electrical signal. A signal processing module is electrically connected to the detection switch, and the signal processing module is used to receive the status electrical signal and identify the occlusion status of the camera; A screen prompt module is connected to the signal processing module. The screen prompt module is used to control the mobile smart screen to output corresponding status prompt information based on the occlusion status of the camera.

[0007] Optionally, the detection switch is a mechanical detection switch; The mechanical detection switch is positioned on the movement trajectory of the physical baffle. When the physical baffle is completely closed to block the camera, the physical baffle presses against the mechanical detection switch, causing the mechanical detection switch to be in an open state. When the physical baffle is completely open to expose the camera, the physical baffle releases its pressure on the mechanical detection switch, causing the mechanical detection switch to be in a closed state.

[0008] Optionally, the detection switch is a non-contact detection element, including any one of an infrared sensor, a photoelectric sensor, or a Hall sensor; The non-contact detection element is disposed on the physical baffle or the machine body, and is used to detect the displacement change of the physical baffle in a non-contact manner; Alternatively, the mobile smart screen camera detection system may further include an electric drive module connected to the physical baffle, used to drive the physical baffle to perform opening or closing actions.

[0009] Optionally, the signal processing module incorporates a dual verification mechanism, and the signal processing module identifies the occlusion state of the camera specifically by: The signal processing module acquires the status electrical signal output by the detection switch, and simultaneously acquires the power supply status signal and / or data transmission status signal of the camera itself. The signal processing module performs cross-verification between the status electrical signal and the power supply status signal and / or data transmission status signal of the camera to determine the actual usability status of the camera.

[0010] Optionally, the screen prompt module is further configured to: When the signal processing module detects that the status electrical signal is inconsistent with the power supply status signal and / or data transmission status signal of the camera, it outputs a fault differentiation prompt on the screen of the mobile smart screen to distinguish whether the current unusable state of the camera is due to physical obstruction or equipment failure.

[0011] Optionally, the status prompt information may take the form of one or more combinations of screen pop-up prompts, screen status bar icon prompts, and voice prompts; Specifically, when the screen prompt module outputs a screen pop-up prompt, upon detecting a change in the status electrical signal, it controls the screen to pop up a status prompt pop-up and controls it to automatically disappear after continuously displaying for a preset duration.

[0012] Optionally, the system further includes a scene recognition module; The scene recognition module is used to detect whether an application scene that requires camera activation has been launched by a preset application whitelist. The application whitelist includes fitness applications, motion-sensing game applications and / or video call applications. When any application in the application whitelist is detected to be launched, the signal processing module automatically detects the current status electrical signal; if it is determined that the physical baffle is in the closed state, the control screen outputs a targeted prompt message to guide the opening of the physical baffle.

[0013] The technical solution adopted by this application to solve the technical problem is as follows: A method for detecting mobile smart screen cameras, applied to the mobile smart screen camera detection system as described above, comprising: The system detects the open or closed state of the physical barrier located in front of the camera and acquires the corresponding state electrical signal generated by the state. Receive the status electrical signal and identify the occlusion status of the camera; Based on the occlusion status of the camera, the mobile smart screen is controlled to output corresponding status prompts.

[0014] In some implementations, receiving the status electrical signal and identifying the occlusion status of the camera specifically includes: The status electrical signal is acquired, and the power supply status signal and / or data transmission status signal of the camera itself are acquired simultaneously for cross-verification to determine the actual usability status of the camera. When the verification detects an inconsistency in the signal, the control screen outputs a fault differentiation prompt to distinguish between physical obstruction and equipment failure.

[0015] In some implementations, the method further includes a scene linkage step: Detect whether an application included in the preset application whitelist has been launched; When the application is detected to be launched, the step of detecting the current state electrical signal is automatically executed; if it is determined that the physical barrier is in a closed state, a targeted prompt message guiding the opening of the physical barrier is output on the screen.

[0016] Beneficial effects: This application provides a mobile smart screen camera detection system and method. The system establishes a linkage between a physical baffle, a detection switch, a signal processing module, and a screen prompt module. This allows the detection switch to convert the open or closed state of the physical baffle into a real-time electrical signal, which is then recognized by the signal processing module and output to the screen prompt module for visual feedback. This establishes a direct correspondence between the physical occlusion state of the camera and the system prompts. Compared to methods that rely solely on software to access the camera's operating status, this solution provides a more accurate physical indication of whether the camera is obstructed, avoiding incorrect status prompts due to system malfunctions or software misjudgments. It retains the absolute privacy protection advantage of physical occlusion, completely blocking the risk of malicious program access, while precise detection and intuitive prompts prevent user misjudgment and simplify the operation process.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0021] Please combine Figures 1 to 6 This embodiment provides a mobile smart screen camera detection system 10 for detecting cameras on mobile smart screens. The mobile smart screen camera detection system 10 includes a physical baffle 11, a detection switch 12, a signal processing module 13, and a screen prompt module 14. In some embodiments, it also includes an electric drive module and a scene recognition module 15. The physical baffle 11 is movably disposed in front of the camera on the mobile smart screen to block or expose the camera. The detection switch 12 is connected to the physical baffle 11 and outputs a corresponding status electrical signal when the position of the physical baffle 11 changes. The signal processing module 13 is electrically connected to the detection switch 12 and receives the status electrical signal to identify the camera's blocking state. The screen prompt module 14 is connected to the signal processing module 13 and controls the mobile smart screen to output corresponding status prompt information based on the camera's blocking state.

[0022] In different implementations, the detection switch 12 can be a mechanical detection switch 12 set on the moving trajectory of the physical baffle 11, or it can be a non-contact detection element set on the physical baffle 11 or the mobile smart screen body; at the same time, the physical baffle 11 can be driven by the electric drive module, and the detection and linkage control of the application scenario can be realized by the scene recognition module 15.

[0023] When the detection switch 12 is a mechanical detection switch 12, the physical baffle 11 moves relative to the camera, directly acting on the detection switch 12 and causing it to output a corresponding status electrical signal. When the detection switch 12 is a mechanical detection switch 12, it is positioned on the movement trajectory of the physical baffle 11. When the physical baffle 11 is completely closed to block the camera, it presses against the mechanical detection switch 12, causing it to be in the open state. When the physical baffle 11 is completely open to expose the camera, it releases its pressure on the mechanical detection switch 12, causing it to be in the closed state, thus forming a status electrical signal that corresponds one-to-one with the open or closed state of the physical baffle 11.

[0024] When the detection switch 12 is a non-contact detection element, it outputs a status electrical signal by detecting the displacement change of the physical baffle 11, achieving an equivalent status detection effect. The aforementioned status electrical signal is transmitted to the signal processing module 13, which identifies the signal to determine whether the camera is in an occluded or unoccluded state, and further generates corresponding camera occlusion status information.

[0025] In a further embodiment, the signal processing module 13 incorporates a dual verification mechanism. It acquires not only the status electrical signal output by the detection switch 12, but also the camera's own power supply status signal and / or data transmission status signal. The module then cross-verifies the status electrical signal with the camera's power supply status signal and / or data transmission status signal to determine the camera's actual usability. Through this cross-verification process, when the status electrical signal of the detection switch 12 matches the camera's power supply status signal and / or data transmission status signal, the signal processing module 13 can confirm that the camera's occlusion state matches its working state. When the two do not match, it determines that the camera is in an abnormal state, thereby avoiding misjudgments caused by a single signal and improving overall detection accuracy.

[0026] Based on the above signal processing results, the screen prompt module 14 works in conjunction with the signal processing module 13. When the signal processing module 13 detects a change in the status electrical signal, i.e., when the physical baffle 11 is opened or closed, the screen prompt module 14 immediately controls the mobile smart screen to display a status prompt pop-up window, and controls the status prompt pop-up window to automatically disappear after being continuously displayed for a preset time, thereby realizing real-time status feedback to the user.

[0027] In a further embodiment, when the signal processing module 13 verifies that the status electrical signal is inconsistent with the power supply status signal and / or data transmission status signal of the camera, the screen prompt module 14 outputs a fault discrimination prompt message on the screen of the mobile smart screen to distinguish whether the current unavailable state of the camera is caused by the physical baffle 11 being blocked or a device failure, thereby achieving a more accurate status prompt.

[0028] In an embodiment including the scene recognition module 15, the scene recognition module 15 is configured to detect whether a preset application scene that requires the camera to be enabled is started. It determines whether the application scene is started by detecting whether the mobile smart screen starts an application program within the application whitelist, where the application whitelist includes fitness applications, somatosensory game applications, and / or video call applications. When it is recognized that the application scene is started, the signal processing module 13 automatically detects the current status electrical signal; if it is determined that the physical baffle 11 is in the closed state, the screen prompt module 14 outputs a targeted prompt message on the screen of the mobile smart screen to guide the opening of the physical baffle 11, thereby achieving the linkage control between the camera status and the application scene and avoiding the situation where the application cannot run properly due to the camera being unavailable.

[0029] Please combine Figures 1 to 5 In a further embodiment, the system may further include an electric drive module. The electric drive module is connected to the physical baffle 11 and is configured to drive the physical baffle 11 to perform an opening or closing action according to a user's control instruction or a system trigger instruction. In this structure, the electric drive module forms a linkage relationship with the detection switch 12, the signal processing module 13, and the screen prompt module 14. That is, during the process of the electric drive module driving the physical baffle 11 to move, the detection switch 12 is synchronously triggered to output a status electrical signal, and the signal processing module 13 performs status recognition and outputs it to the screen prompt module 14, thereby achieving the synchronization between the automatic movement of the physical baffle 11 and the status prompt.

[0030] In a further embodiment, the status prompt message output by the screen prompt module 14 can adopt a combination form of one or more of screen pop-up prompts, screen status bar icon prompts, and voice prompts, thereby achieving diverse information prompt methods in different usage scenarios. Through the synergistic effect between the above various structures, the mobile smart screen camera detection system 10 realizes the synchronous detection and linkage prompt of the status of the physical baffle 11 and the camera status, enabling the actual available status of the camera to be accurately identified and feedback, effectively solving the problem in the prior art that there is no linkage between physical occlusion and software prompts and it is difficult to accurately feedback the actual available status of the camera module.

[0031] Please combine Figures 1 to 5In some embodiments, the mobile smart screen camera detection system 10 includes a physical baffle 11, a detection switch 12, a signal processing module 13, and a screen prompt module 14. The physical baffle 11 is movably disposed in front of the camera of the mobile smart screen to block or expose the camera. The detection switch 12 is connected to the physical baffle 11 and is used to detect the open or closed state of the physical baffle 11 and output a corresponding status electrical signal. The signal processing module 13 is electrically connected to the detection switch 12 and is used to receive the status electrical signal and identify the blocking state of the camera. The screen prompt module 14 is connected to the signal processing module 13 and is used to control the screen of the mobile smart screen to output corresponding status prompt information according to the blocking state of the camera. Furthermore, by establishing a linkage between the physical baffle 11, the detection switch 12, the signal processing module 13, and the screen prompt module 14, the open or closed state of the physical baffle 11 can be converted into a status electrical signal in real time by the detection switch 12. This signal is then recognized by the signal processing module 13 and output to the screen prompt module 14 for visual feedback, thereby achieving a direct correspondence between the physical occlusion state of the camera and the system prompts. Compared to methods that rely solely on software to call the camera's working status, this solution can realistically reflect whether the camera is occluded at the physical level, avoiding incorrect status prompts caused by system anomalies or software misjudgments, and improving the authenticity and reliability of the camera status feedback.

[0032] Please combine Figure 4 In some embodiments, the detection switch 12 is a mechanical detection switch 12; the mechanical detection switch 12 is disposed on the movement trajectory of the physical baffle 11; when the physical baffle 11 is completely closed to block the camera, the physical baffle 11 presses the mechanical detection switch 12, causing the mechanical detection switch 12 to be in an open state; when the physical baffle 11 is completely open to expose the camera, the physical baffle 11 releases its pressure on the mechanical detection switch 12, causing the mechanical detection switch 12 to be in a closed state. Furthermore, by specifically configuring the detection switch 12 as a mechanical detection switch 12 located on the movement trajectory of the physical baffle 11, when the physical baffle 11 moves to its open or closed limit position, it can directly trigger the mechanical detection switch 12 to form a stable open or closed state, thereby establishing a one-to-one correspondence between the output state electrical signal and the actual position of the physical baffle 11. This structure provides a clear boundary for state determination, avoiding state ambiguity caused by intermediate positions. Simultaneously, the mechanical triggering method has the characteristics of simple structure and direct response, which is beneficial to improving the certainty of the detection results and the overall stability of the system.

[0033] In some embodiments, the detection switch 12 is a non-contact detection element, which includes any one of an infrared sensor, a photoelectric sensor, or a Hall sensor; The non-contact detection element is disposed on the physical baffle 11 or the body of the mobile smart screen. This non-contact detection element detects the displacement change of the physical baffle 11 in a non-contact manner, outputting the status electrical signal. Furthermore, by optimizing the detection method to a non-contact detection element, such as an infrared sensor, photoelectric sensor, or Hall sensor, the physical baffle 11 can achieve status recognition without direct contact with the detection structure during movement, effectively avoiding problems such as mechanical contact wear and poor contact. This reduces the risk of detection errors due to long-term use and improves the reliability and maintainability of the system.

[0034] In some embodiments, the mobile smart screen camera detection system 10 further includes an electric drive module; the electric drive module is connected to the physical baffle 11, and is used to drive the physical baffle 11 to perform opening or closing actions according to user control commands or system trigger commands. Furthermore, by setting up the electric drive module and connecting it to the physical baffle 11, the opening or closing of the physical baffle 11 can be automatically completed through electronic control, thereby reducing manual operation steps. On this basis, the electric drive action can be synchronized with the detection switch 12 and the signal processing module 13, making the baffle action, status detection, and prompt output a unified and coordinated process, which not only improves the system's automation level but also enhances the overall convenience and consistency of operation.

[0035] In some implementations, the original structure of "manual physical baffle 11 combined with mechanical detection switch 12" can be replaced with an overall architecture of "electric baffle combined with Hall sensor" to achieve automatic control and status detection of the baffle. Specifically, by connecting an electric drive module (such as a micro motor) to the physical baffle 11, the user can trigger a control signal through the screen buttons or voice commands of the mobile smart screen to drive the electric drive module to perform opening or closing actions on the physical baffle 11, thereby replacing manual operation. At the same time, magnets and Hall sensors are respectively set at corresponding positions on the electric baffle and the mobile smart screen body. The Hall sensor detects changes in the distance of the magnet and outputs corresponding status electrical signals to determine whether the physical baffle 11 is in an open or closed state. The status electrical signals are further transmitted to the signal processing module 13 for identification and trigger the screen prompt module 14 to output corresponding status prompt information, while realizing linkage control with preset application scenarios.

[0036] In some implementations, the signal processing module 13 incorporates a dual verification mechanism. Specifically, the signal processing module 13 identifies the occlusion status of the camera by: acquiring the status electrical signal output by the detection switch 12, and simultaneously acquiring the camera's own power supply status signal and / or data transmission status signal; the signal processing module 13 cross-verifies the status electrical signal with the camera's power supply status signal and / or data transmission status signal to determine the actual usability of the camera. Furthermore, by introducing the camera's power supply status signal and / or data transmission status signal into the signal processing module 13 and cross-verifying it with the status electrical signal output by the detection switch 12, the system can not only determine whether the camera is physically obstructed, but also further determine whether the camera is in normal working condition. Through multi-source signal fusion judgment, the misjudgment problem caused by a single signal source is effectively avoided. When the occlusion status and working status are inconsistent, it can be identified as an abnormal situation, thereby improving the accuracy and intelligence level of camera status judgment.

[0037] In some implementations, the dual verification mechanism in this application can be replaced by retaining the status detection and prompting function. Specifically: the verification of camera power supply and data transmission status can be cancelled, and the camera status can only be determined by detecting the signal of switch 12. At the same time, a "timed self-test" function can be added to perform a self-test on the detection switch 12 at regular intervals, such as 10 to 20 seconds, to avoid misjudgments caused by switch failure; or the verification signal source can be replaced by the sensor signal from the camera's lens cap, if the camera has a built-in lens cap sensor; the power supply and data transmission signals can be replaced and cross-verified with the signal of detection switch 12. This simplifies the verification logic, reduces the difficulty of software development, and saves development costs.

[0038] In some embodiments, the screen prompt module 14 is further configured to output fault differentiation prompt information on the screen of the mobile smart screen when the signal processing module 13 detects that the status electrical signal is inconsistent with the power supply status signal and / or data transmission status signal of the camera. This distinguishes whether the current unavailability of the camera is due to physical obstruction or device malfunction. Specifically, if the detection switch 12 displays "closed" but the camera has no power supply, a differentiated prompt pops up on the screen to clearly distinguish the fault type, such as "The camera is on, but the device is faulty and cannot be used normally. Please check the device." This helps users quickly locate the problem. Furthermore, by outputting fault differentiation prompt information when the status electrical signal is detected to be inconsistent with the camera's power supply status signal and / or data transmission status signal, the system can distinguish whether the camera's unavailability is caused by physical obstruction or device malfunction. This refined prompt mechanism avoids the problem of "only prompting unavailability without knowing the reason" in traditional solutions, helps users quickly locate the source of the problem, improves troubleshooting efficiency, and has good practical value.

[0039] In some implementations, when the screen prompt module 14 outputs the corresponding status prompt information, it specifically includes: when the signal processing module 13 detects a change in the status electrical signal, i.e., when the physical baffle 11 is operated to open or close, it immediately controls the mobile smart screen to pop up a status prompt pop-up window, and controls the status prompt pop-up window to automatically disappear after being continuously displayed for a preset time. Specifically, when the user manually opens or closes the physical baffle 11, the switch 12 is detected to trigger a change in status, and the main control board immediately controls the screen to pop up a pop-up prompt. If the pop-up window disappears automatically after 3-5 seconds, it avoids affecting the user's normal use and clearly displays the current camera status—when the baffle is closed, it prompts "Camera is blocked, privacy is protected"; when the baffle is open, it prompts "Camera is on, can be used normally". Further, the pop-up prompt can be changed to a screen status bar icon prompt, such as displaying a "shield" icon when blocked and a "camera" icon when open, and at the same time, it can be combined with voice prompts to replace the triggering logic of the pop-up prompt. Furthermore, by controlling the screen notification module 14 to output a pop-up notification when the camera status changes, and automatically disappearing after a preset time, the user can be informed of the camera status change immediately, while avoiding the notification information occupying screen resources for an extended period. This dynamic notification mechanism ensures both the timeliness of information delivery and the simplicity and user experience of the user interface, avoiding continuous notifications from interfering with user operations.

[0040] Please combine Figure 5 In some embodiments, the mobile smart screen camera detection system 10 further includes a scene recognition module 15. The scene recognition module 15 is used to detect whether a preset application scenario requiring camera activation has been started. When the application scenario is detected as being activated, the signal processing module 13 automatically detects the current state electrical signal. If it is determined that the physical baffle 11 is in a closed state, the screen prompt module 14 outputs targeted prompts on the mobile smart screen guiding the user to open the physical baffle 11. Furthermore, by setting the scene recognition module 15 and recognizing camera usage scenarios based on an application whitelist, the system can proactively detect the camera status when a specific application, such as fitness, motion-sensing games, or video calls, is detected and launched. When the physical baffle 11 is detected as being in a closed state, prompts guiding the user to open the baffle are automatically output, thereby achieving intelligent linkage between camera status and application scenarios. This solution effectively avoids the problem of applications failing to function properly due to the user not turning on the camera, improving the intelligence level of the device and the user experience.

[0041] Please combine Figure 5In some implementations, the scene recognition module 15 detects whether a preset application scenario requiring camera activation has been launched: a pre-defined application whitelist, which includes fitness applications, motion-sensing game applications, and / or video call applications; wherein, when the mobile smart screen launches any application within the application whitelist, it is determined that the application scenario has been launched. Furthermore, by setting up the scene recognition module 15 and recognizing camera usage scenarios based on the application whitelist, the system can proactively detect the camera status when a specific application, such as fitness, motion-sensing game, or video call, is detected and launched. When the physical baffle 11 is detected to be in a closed state, a prompt message guiding the opening of the baffle is automatically output, thereby achieving intelligent linkage between camera status and application scenario. This solution effectively avoids the problem of applications failing to function properly due to the user not turning on the camera, improving the device's intelligence level and user experience.

[0042] In some implementations, the status notification information may take the form of one or more combinations of on-screen pop-up notifications, on-screen status bar icon notifications, and voice notifications. By setting the screen notification method to one or more combinations of pop-up notifications, status bar icon notifications, and voice notifications, the system can provide diverse information feedback methods in different usage scenarios. For example, voice notifications can be used to remind users when they are not looking directly at the screen, while icon notifications can be used when continuous status indication is needed, thereby improving the flexibility and coverage of information delivery and further optimizing the user interaction experience.

[0043] In other embodiments, this application develops a dedicated detection switch 12 interface and driver for different models of mobile smart screens to achieve targeted hardware and software adaptation. The detection switch 12 is integrated into the smart screen body and around the camera, rather than on the physical baffle 11, and the switch is triggered by the mechanical displacement when the baffle is opened / closed.

[0044] In other embodiments, this application may also employ an overall architecture combining a physical baffle 11 with software image recognition detection. Specifically, the original manual physical baffle 11 is retained without adding any additional hardware detection components. The image recognition algorithm built into the mobile smart screen is used to collect the camera's captured image in real time. If the image is completely obstructed, i.e., there is no image information, it is determined that the baffle is closed, and a prompt is simultaneously given on the screen. If the image is normal and there is image information, it is determined that the baffle is open, thus completing the status detection and prompt.

[0045] Please combine Figure 6 This application also provides a method for detecting mobile smart screen cameras, applied to the mobile smart screen camera detection system described above, the method comprising: S100: Detect the open or closed state of the physical baffle set in front of the camera, and acquire the corresponding state electrical signal generated by the state. Specifically: when the physical baffle moves relative to the camera, a detection switch set on the physical baffle or on its movement trajectory is triggered; when the physical baffle is in the closed position to block the camera, the physical baffle acts on the detection switch to put it in the first state and outputs a corresponding status electrical signal; when the physical baffle is in the open position to expose the camera, the physical baffle disengages from or changes its effect on the detection switch, putting the detection switch in the second state and outputting a corresponding status electrical signal; the status electrical signal changes with the opening or closing state of the physical baffle.

[0046] S200: Receive the status electrical signal and identify the occlusion status of the camera; Specifically: The signal processing module receives the status electrical signal output by the detection switch, and performs identification processing on the status electrical signal, corresponding the electrical signals of different states to the state of the camera being blocked or the state of the camera not being blocked, thereby determining the current occlusion status of the camera.

[0047] S210, Receiving the status electrical signal and identifying the occlusion status of the camera; specifically including: The status electrical signal is acquired, and the power supply status signal and / or data transmission status signal of the camera itself are acquired simultaneously for cross-verification to determine the actual usability status of the camera. Specifically: While acquiring the status electrical signal output by the detection switch, the signal processing module reads the power supply status signal and / or the data transmission status signal of the camera, and compares and analyzes the status electrical signal with the power supply status signal and / or data transmission status signal; when the status electrical signal is consistent with the camera power supply status signal and / or data transmission status signal, it is determined that the camera is in a normal usable or normally blocked state; when the status electrical signal is inconsistent with the camera power supply status signal and / or data transmission status signal, it is determined that the camera has an abnormal state.

[0048] S300. Based on the occlusion status of the camera, control the mobile smart screen to output corresponding status prompt information.

[0049] When the verification detects an inconsistency in the signal, the control screen outputs a fault differentiation prompt to distinguish between physical obstruction and equipment failure.

[0050] Specifically: The signal processing module sends the identified camera occlusion status to the screen prompt module, which then controls the mobile smart screen to output corresponding status prompt information. When a status change caused by the opening or closing of a physical baffle is detected, a status prompt pop-up appears on the screen and disappears automatically after being displayed for a preset duration. When the signal processing module determines that the status electrical signal is inconsistent with the camera power supply status signal and / or data transmission status signal, the screen prompt module outputs a fault differentiation prompt on the screen to indicate that the current unusable state of the camera is caused by physical baffle occlusion or equipment failure.

[0051] In some implementations, the method further includes a scene linkage step: detecting whether an application included in a preset application whitelist has been launched; when the application is detected to be launched, automatically executing the step of detecting the current state electrical signal; if it is determined that the physical baffle is in a closed state, outputting targeted prompt information on the screen to guide the opening of the physical baffle.

[0052] Specifically: The scene recognition module detects whether an application on the pre-set application whitelist is running on the mobile smart screen. The application whitelist includes fitness applications, motion-sensing game applications, and / or video call applications. When the application is detected to be running, the signal processing module is triggered to obtain the status electrical signal output by the current detection switch and determine the current status of the physical baffle. When it is determined that the physical baffle is in the closed state, the screen prompt module is controlled to output a prompt message on the screen to guide the user to open the physical baffle so that the camera can meet the usage requirements of the application.

[0053] In summary, this application provides a mobile smart screen camera detection system and method. The mobile smart screen camera detection system includes: a physical baffle, which is movably disposed in front of the camera of the mobile smart screen to block or expose the camera; a detection switch, which is connected to the physical baffle and is used to detect the open or closed state of the physical baffle and output a corresponding status electrical signal; a signal processing module, which is electrically connected to the detection switch and is used to receive the status electrical signal and identify the occlusion state of the camera; and a screen prompt module, which is connected to the signal processing module and is used to control the screen of the mobile smart screen to output corresponding status prompt information according to the occlusion state of the camera. Furthermore, by setting the linkage relationship between the physical baffle, the detection switch, the signal processing module, and the screen prompt module, the open or closed state of the physical baffle can be converted into a status electrical signal in real time by the detection switch, and then identified by the signal processing module and output to the screen prompt module for visual feedback, thereby realizing a direct correspondence between the physical occlusion state of the camera and the system prompt. Compared to methods that rely solely on software to access camera status, this solution can physically reflect whether the camera is obstructed, avoiding incorrect status prompts caused by system malfunctions or software misjudgments, and improving the authenticity and reliability of camera status feedback.

[0054] It should be understood that the application of this application is not limited to the examples above. Those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
