As technology has progressed, many kinds of electronic devices such as smartphones have begun to include the functionality of digital photography or video recording. A user can use the electronic device to capture various images using the camera module of the electronic device.

However, today's society pays more and more attention to personal privacy, but a camera module of an electronic device has a risk of exposing personal privacy. For example, a hacker may illegally or irregularly hack into a user's electronic device, and the user's normal behavior may be seen or recorded without the user's awareness. Therefore, to reduce this risk, many users may use a patch, a piece of black tape, or another attachable blocking object to physically block the lens of the camera module, so as to prevent the lens of the camera module from capturing images or recording video. However, these solutions give the electronic device a bad appearance, and the blocking object cannot be easily detached from or installed on the electronic device.

The monitoring circuit 1021 provides the processing capability required to execute an operating system, programs, user graphic interface (GUI), software, modules, application, and other functions of the electronic device 100. The monitoring circuit 1021 may include a single processor or it may include a plurality of processors. For example, the monitoring circuit 1021 may include general purpose microprocessors, a combination of general and special purpose microprocessors, such as instruction-set processors, graphics processors, video processors, audio processors and special purpose microprocessors.

Data used by the monitoring circuit 1021 are stored in the storage circuit 1023.

It should be understood that the electronic device 100 is only one example of the electronic device of the present disclosure. The electronic device 100 can have more or less components in the figures, or has a different configuration of components.

The storage circuit 1023 can store an operation system for being performed by the electronic device 100. These operation systems can include Android, Berkeley Software Distribution (BSD), iPhone OS (iOS), Linux, OS X, Unix-like Real-time Operating System(e.g., QNX), Darwin, UNIX, Microsoft Windows, Window Phone and IBM z/OS, but they are not limited thereto.

Next, please refer to FIG. 1 to FIG. 3 together. FIG. 2 shows a schematic diagram of a blocking module 200 according to the embodiment of the present disclosure. FIG. 3 shows a sectional view of the blocking module 200, the camera module 106 and the front covering plate 1041 according to the embodiment of the present disclosure. As shown in FIG. 1, the electronic device 100 can further include a blocking module 200. The blocking module 200 is detachably disposed on the front covering plate 1041 and is aligned with the camera module 106 and the first capacitive sensing element 108. That is, the front covering plate 1041 is located between the camera module 106 and the blocking module 200, and the blocking module 200 is configured to block the lens of the camera module 106, so as to prevent a hacker from hacking the electronic device 100 and peeping through the camera module 106 to watch the user.

As shown in FIG. 2 and FIG. 3, the blocking module 200 can includes a base 202, a moving member 204 and a first conductive element 206. A sliding slot 2021 can be formed on the base 202 so that the moving member 204 can move relative to the base 202 and the camera module 106 along the sliding slot 2021, such as moving along the X-axis direction. As shown in FIG. 3, the moving member 204 can include a first end portion 2041, a connecting portion 2043 and a second end portion 2045. The connecting portion 2043 is connected between the first end portion 2041 and the second end portion 2045, and the first conductive element 206 is disposed on the bottom of the moving member 204. That is, the first conductive element 206 is disposed on the bottom of the second end portion 2045.

In some embodiments of the disclosure, the moving member 204 is made of plastic or other non-conductive materials, and the first conductive element 206 is made of a conductive material. For example, the first conductive element 206 can be made of silver, aluminum, platinum, cooper, and so on, but it is not limited thereto. Furthermore, the first conductive element 206 can be also a conductive fabric or a conductive tape. In addition, it is noted that the blocking module 200 has a thickness H1 along the Z-axis direction, and the thickness H1 is 2 mm or less than 2 mm in this embodiment so as to facilitate the user to install the blocking module 200 on the front covering plate 1041.

As shown in FIG. 3, the blocking module 200 is disposed on the front covering plate 1041. For example, the blocking module 200 is stuck to the front covering plate 1041, but the manner of disposing the blocking module 200 on the front covering plate 1041 is not limited thereto. The front covering plate 1041 is made of a plastic material and include a through hole 1045. In addition, the base 202 can further include an opening 2023, communicated with the sliding slot 2021 and the through hole 1045. Moreover, the camera module 106 can include a circuit board 1061 and a lens 1063 disposed on the circuit board 1061. As shown in FIG. 3, the lens 1063 is aligned with the through hole 1045 and the opening 2023 so that the lens 1063 can receive the light beams traveling through the opening 2023 and the through hole 1045, so as to perform the functions of capturing still images or recording video.

As shown in FIG. 3, the first capacitive sensing element 108 is disposed on an inner side of the front covering plate 1041, and when the moving member 204 is located in the rightmost position (which can be defined as a first position), the moving member 204 is aligned with the first capacitive sensing element 108. In this embodiment, the first capacitive sensing element 108 can be disposed on a flexible printed circuit board 109. For example, the flexible printed circuit board 109 is disposed on the inner side of the front covering plate 1041 and is electrically connected to the monitoring circuit 1021 so that the monitoring circuit 1021 can receive signals from the first capacitive sensing element 108 on the flexible printed circuit board 109.

When the moving member 204 is located in the first position, the first capacitive sensing element 108 senses the first conductive element 206 so as to generate a sensing signal, and the sensing signal can serve as an enable signal, such as a low logical state of digital signals. Then, the monitoring circuit 1021 enables the camera module 106 according to the enable signal, such as providing the camera module 106 with electricity. In addition, the monitoring circuit 1021 can also execute an application stored in the storage circuit 1023 according to the enable signal, such as to execute a camera application, a video-recording application, and so on.

Please refer to FIG. 3, and FIG. 4. FIG. 4 is a diagram illustrating that the moving member 204 moves from the first position in FIG. 3 to a different position according to the embodiment of the disclosure. When the moving member 204 is forced to move from the rightmost position of the base 202 to the position shown in FIG. 4, the moving member 204 is located in the leftmost position of the base 202 (the leftmost position can be defined as a second position). At this time, the moving member 204 completely blocks the opening 2023 and the lens 1063 of the camera module 106. At this time, because the first conductive element 206 is away from the upper side of the first capacitive sensing element 108, the first capacitive sensing element 108 does not sense the first conductive element 206 and therefore the sensing signal changes. For example, the sensing signal changes from a low logical state to a high logical state of digital signals. Therefore, the monitoring circuit 1021 determines that the moving member 204 has already blocked the camera module 106 according to the sensing signal, and then the monitoring circuit 1021 can stop providing the camera module 106 with electricity, so as to turn off the camera module 106. Furthermore, when the moving member 204 is located in the second position, the monitoring circuit 1021 can also close the camera application or the video-recording application correspondingly.

It can be well known based on the above description that, in order to prevent a hacker from hacking the electronic device 100 and peeping through the camera module 106 to spy on the user, the user can stick the very thin blocking module 200 directly onto the front covering plate 1041 and then move the moving member 204 to block or reveal the camera module 106, so as to turn the camera module 106 off or on.

Please refer to FIG. 5, which shows a sectional view of the blocking module 200, the camera module 106 and the front covering plate 1041 according to another embodiment of the present disclosure. The structures of this embodiment are similar to the structures of the previous embodiment, and the difference is that the first capacitive sensing element 108 can be integrated in the camera module 106, such as being disposed on the circuit board 1061, and then the first capacitive sensing element 108 can be electrically connected to the monitoring circuit 1021 through the circuit lines of the circuit board 1061. Therefore, an additional flexible printed circuit board is not needed in this embodiment. As a result, not only is the manufacturing cost of the electronic device 100 reduced, but also the manufacturing process of the electronic device 100 is simplified. It should be noted that the first capacitive sensing element 108 can be disposed on the circuit board 1061 or the front covering plate 1041, and its position depends on practical design requirements. In addition, the operations of the blocking module 200 and the monitoring circuit 1021 in this embodiment are similar to the previous embodiment, and they are omitted herein.

Please refer to FIG. 6, which shows a sectional view of a blocking module 200A, the camera module 106 and a front covering plate 1041A according to another embodiment of the present disclosure. In this embodiment, the front covering plate 1041A cam be made of a glass material, and a base 202A of the blocking module 200A can include an opening slot 2025. As shown in FIG. 6, the opening slot 2025 penetrates the bottom of the base 202A, and the moving member 204 moves along the opening slot 2025 relative to the base 202A and the camera module 106. In this embodiment, the first conductive element 206 is located between the moving member 204 and the front covering plate 1041A. In particular, the first conductive element 206 is located on the bottom of the second end portion 2045 of the moving member 204 and is in contact with the front covering plate 1041A. However, in other embodiments, the first conductive element 206 is not in contact with the front covering plate 1041A.

In addition, in this embodiment, the first capacitive sensing element 108 is disposed on the circuit board 1061 of the camera module 106 to be electrically connected to the monitoring circuit 1021, but it is not limited thereto. For example, in other embodiments, the first capacitive sensing element 108 can be disposed on a flexible printed circuit board similar to the embodiment of FIG. 3, and the flexible printed circuit board adheres to the inner side of the front covering plate 1041A. The position of the first capacitive sensing element 108 depends on practical design requirements.

Please refer to FIG. 7, which shows a sectional view of the blocking module 200A, the camera module 106 and the front covering plate 1041A according to another embodiment of the present disclosure. This embodiment is similar to the embodiment of FIG. 6, and the difference between these two embodiments is that the electronic device in this embodiment can further include a conducting layer 110 disposed on the inner side of the front covering plate 1041A. In this embodiment, the front covering plate 1041A can be the topmost glass layer of a touch panel, and the conducting layer 110 can be included in a touch layer of the touch panel. The conducting layer 110 is disposed on the inner side of the front covering plate 1041A and is electrically connected to the monitoring circuit 1021. The type of the touch panel can be GFF, GF, OGS, OGM, GMM, and so on, and the conducting layer 110 can be any one layer in a touch panel of the previous type.

As shown in FIG. 7, the first capacitive sensing element 108 can be formed in the conducting layer 110 and is configured to sense the first conductive element 206. It should be noted that the first capacitive sensing element 108 can be formed in the conducting layer 110. For example, the first capacitive sensing element 108 is directly formed in the conducting layer 110 when manufacturing the display screen 105 and the front covering plate 1041A, so that an additional circuit board is not needed in the structural design of this embodiment. As a result, not only is reduced the manufacturing cost of the electronic device 100, but also the manufacturing process of the electronic device 100 is simplified.

Please refer to FIG. 8A, which shows a top view of the base, the first capacitive sensing element 108 and a second capacitive sensing element 112 according to the embodiment of the disclosure. In this embodiment, the base can be the base 202A, or also can be the base 202. The moving member 204 and the first conductive element 206 are omitted in FIG. 8A and FIG. 8B for clarity.

As shown in FIG. 8A, the first capacitive sensing element 108 is disposed at the right side of the bottom of the base 202A (corresponding to the first position). In addition, the electronic device can include the second capacitive sensing element 112, disposed below the base 202A along the Z-axis direction. The blocking module 200A further includes a second conductive element 208 corresponding to the second capacitive sensing element 112, and the second conductive element 208 is disposed on the bottom of the base 202A. In this embodiment, the second conductive element 208 has a rectangular structure and is disposed on a long side of the base 202A, and the second capacitive sensing element 112 also has a rectangular structure corresponding to the second conductive element 208. In this embodiment, the first capacitive sensing element 108 and the second capacitive sensing element 112 are electrically connected to the monitoring circuit 1021 through conductive lines WR.

In this embodiment, the second capacitive sensing element 112 is configured to sense the second conductive element 208 and outputs a sensing value, and the monitoring circuit 1021 can receive and monitor the sensing value, so as to determine whether the second capacitive sensing element 112 is aligned with the second conductive element 208. For example, the monitoring circuit 1021 can compare the sensing value with a preset threshold value. When the sensing value is greater than the preset threshold value, the monitoring circuit 1021 determines that the second conductive element 208 is aligned with the second capacitive sensing element 112. That is, the blocking module 200A is aligned with the camera module 106. In contrast, when the sensing value is less than the preset threshold value, the monitoring circuit 1021 determines that the second capacitive sensing element 112 is not aligned with the second conductive element 208.

When the monitoring circuit 1021 determines that the second conductive element 208 is not aligned with the second capacitive sensing element 112, it indicates that the blocking module 200A is not aligned with the camera module 106. Therefore, the monitoring circuit 1021 can control the display screen 105 to display a notification message, such as a dialog window, to notify the user of installing the blocking module 200A onto the front covering plate 1041 again, so as to align the blocking module 200A with the camera module 106.

Please refer to FIG. 8B to FIG. 8D, which show a top view of the base, the first capacitive sensing element 108 and the second capacitive sensing element 112 according to some embodiments of the disclosure. As shown in FIG. 8B, the second conductive element 208 has a U-shaped structure corresponding the shape of the base 202A, and the second capacitive sensing element 112 also correspondingly has a U-shaped structure.

In addition, as shown in FIG. 8C and FIG. 8D, there can be two second conductive elements 208 disposed on the bottom of the base 202A, and the electronic device 100 can correspondingly include two second capacitive sensing elements 112. In the embodiment of FIG. 8C, the two second conductive elements 208 are disposed on two short sides of the base 202A, and the two second capacitive sensing elements 112 are correspondingly respectively disposed below the two second conductive elements 208 along the Z-axis direction. In the embodiment of FIG. 8D, the two second conductive elements 208 are disposed on two long sides of the base 202A, and the two second capacitive sensing elements 112 are correspondingly respectively disposed below the two second conductive elements 208 along the Z-axis direction.

Based on the design of the embodiments in FIG. 8B to FIG. 8D, the accuracy of determining whether the base 202A is aligned with the camera module 106 by the monitoring circuit 1021 can be increased.

Please refer to FIGS. 9A and 9B, which shows a flowchart of the method of switching the camera module 106 according to some embodiments of the disclosure. In step S100, a blocking module 200 is disposed on the camera module 106 of the electronic device 100. In step S102, when the blocking module 200 is disposed above the camera module 106, a second capacitive sensing element 112 senses the second conductive element 208 on the blocking module 200 to output a sensing value. In step S104, the monitoring circuit 1021 can determine whether the blocking module 200 is aligned with the camera module 106 according to the sensing value. For example, the monitoring circuit 1021 can compare the sensing value with a preset threshold value. When the sensing value is greater than the preset threshold value, the monitoring circuit 1021 determines that the blocking module 200 is aligned with the camera module 106, and step S106 is performed. When the sensing value is less than the preset threshold value, the monitoring circuit 1021 determines that the blocking module 200 is not aligned with the camera module 106, and step S114 is performed.

In step S106, a first capacitive sensing element 108 senses a first conductive element 206 on the moving member 204 of the blocking module 200, so as to generate a sensing signal. Next, in step S108, the monitoring circuit 1021 determines whether the moving member 204 is located in the first position according to the sensing signal. When the moving member 204 is located in the first position, step S110 is performed. When the moving member 204 is located in a second position instead of the first position, step S112 is performed.

In step S110, when the moving member 204 is located in the first position, the electronic device 100 provides the camera module 106 with electricity, so as to enable the camera module 106. In step S112, when the moving member 204 is located in the second position instead of the first position, the electronic device 100 stops providing electricity, so as to turn off the camera module 106, and the moving member 204 blocks a lens 1063 of the camera module 106 at this time.

In step S114, when the monitoring circuit 1021 determines that the blocking module 200 is not aligned with the camera module 106, the monitoring circuit 1021 controls a display screen 105 of the electronic device 100 to show a notification message.

In contrast to the prior art, the present disclosure provides an electronic device 100 which includes a detachable blocking module, and the user can install the blocking module 200 or the blocking module 200A above the camera module 106 of the electronic device 100. The monitoring circuit 1021 can determine whether the moving member 204 of the blocking module 200 blocks the lens 1063 of the camera module 106 according to the sensing signal outputted from the first capacitive sensing element 108 when the first capacitive sensing element 108 senses the first conductive element 206, so as to determine whether to provide the camera module 106 with electricity to enable the camera module 106 or to stop providing electricity to turn off the camera module 106.

In addition, the monitoring circuit 1021 can further determine whether the blocking module 200 is aligned with the camera module 106 according to the sensing value outputted from the second capacitive sensing element 112 when the second capacitive sensing element 112 senses the second conductive element 208. When the blocking module 200 is not aligned with the camera module 106, the monitoring circuit 1021 can control the display screen 105 to display a notification message to notify the user about the installation of the blocking module 200 again, so that the blocking module 200 can be aligned with the camera module 106. As a result, the monitoring circuit 1021 can more accurately monitor the position of the moving member 204.

Therefore, the electronic device 100 having a blocking module can not only solve the problem of hackers hacking into the electronic device 100 and peeping through the camera module 106, but also has the advantage of saving power. In addition, because the first capacitive sensing element 108 and the second capacitive sensing element 112 can be formed together in the touch layer during the manufacturing of the touch panel, the electronic device 100 also has the advantages of reducing the manufacturing cost and simplifying the manufacturing process.
