Specifically, when the first electronic device meets a first preset condition, a target operation corresponding to the first control information may be executed; under the condition that the first electronic device does not meet the first preset condition, the first electronic device may not respond to the first control information, or send the first feedback information to the first electronic device, that is, prohibit the first electronic device from using the target camera module. And the target camera module comprises a plurality of working modes, each working mode is at least associated with one electronic device, and the first working mode is one working mode in the plurality of working modes. Therefore, the situation that any person or any electronic equipment is connected at will and uses the target camera module can be avoided, the target camera module can be used by the illegal user or the electronic equipment except the electronic equipment associated with the first working mode, data leakage in the camera module is avoided, and the safety of the shared camera module (such as a detachable camera module) is improved.

The mobile electronic device may be a mobile phone, a tablet computer, a notebook computer, a palm computer, a vehicle-mounted terminal, a wearable device, an ultra-mobile personal computer (UMPC), a netbook or a Personal Digital Assistant (PDA), etc.; the non-mobile electronic device may be a Personal Computer (PC), a Television (TV), a teller machine, a self-service machine, or the like; the embodiments of the present invention are not particularly limited.
In the camera module control method provided by the embodiment of the present invention, the execution main body may be the camera module, or a Central Processing Unit (CPU) of the camera module, or a control module in the camera module for executing the camera module control method. In the embodiment of the present invention, a method for controlling a camera module by a camera module is taken as an example to describe the camera module control method provided in the embodiment of the present invention.
In the following embodiments, a method for executing a camera module by a target camera module is taken as an example to describe the camera module control method provided by the embodiments of the present invention.
The following describes in detail a camera module control method according to an embodiment of the present invention with reference to a flowchart of the camera module control method shown in fig. 1. Although the logic sequence of the camera module control method provided by the embodiment of the invention is shown in the method flow chart, in some cases, the steps shown or described may be executed in a different sequence from the sequence here. For example, the camera module control method illustrated in fig. 1 may include S101 to S103:
s101, under the condition that the working mode of the target camera module is the first working mode, the target camera module receives first control information sent by first electronic equipment.
Accordingly, the first electronic device may transmit the first control message to the target camera module before the target camera module performs S101.
And S102, under the condition that the first electronic equipment meets a first preset condition, the target camera module executes target operation corresponding to the first control information.
Wherein, the first preset condition comprises: the first electronic device is a preset electronic device associated with the first working mode.
Illustratively, the target operation is that the target camera module performs a photographing function or a video recording function, and at this time, the target camera module can acquire images in real time. Or, the target operation is that the target camera module accesses data stored in the target camera module, such as data of a certain picture. Of course, the target operation may also be an operation performed by any other target camera module, which is not limited in this embodiment of the present invention.
And S103, under the condition that the first electronic equipment does not meet the first preset condition, the target camera module does not respond to the first control information, or first feedback information is sent to the first electronic equipment.
The first feedback information is information indicating that the first electronic equipment prohibits using the target camera module.
Accordingly, after "sending the first feedback information to the first electronic device" in step 103, the first electronic device may receive the first feedback information sent by the target camera module.
It can be understood that after the first electronic device sends the first control information, if any message sent by the target camera module is not received (for example, within a certain time) or first feedback information sent by the target camera module is received, it can be known that the target camera module prohibits the first electronic device from using the target camera module.
Optionally, after the first electronic device learns that the target camera module prohibits the first electronic device from using the target camera module, a prompt message may be output to prompt a user of the first electronic device to prohibit the first electronic device from using the target camera module, that is, the target camera module is unavailable.
Specifically, the target camera module comprises a plurality of working modes, each working mode is associated with at least one electronic device, and the first working mode is one of the working modes.
Optionally, the camera module control method according to the embodiment of the present invention may determine, according to the user requirement of the user, parameters such as the usage right of the target camera module, the environment (such as an office or a home) where the target camera module is located, and device parameters (such as the number of lenses or pixels of the lenses) of the target camera module, as electronic devices pre-associated with different working modes of the target camera module. For example, the electronic devices associated in advance with the operation mode with the higher usage authority of the target camera module are more, and the electronic devices associated in advance with the operation mode with the lower usage authority of the target camera module are fewer. When the working mode indicates that the target camera module is located in the office of the user, the electronic equipment pre-associated with the target camera module is the electronic equipment located in the office; when the operation mode indicates that the target camera module is located at the home of the user, the electronic device associated with the target camera module in advance is an electronic device located at the home.
In the camera module control method provided by the embodiment of the present invention, after the working mode of the target camera module is the first working mode and the first control information sent by the first electronic device is received, whether the first electronic device meets the first preset condition, that is, whether the first electronic device is a preset electronic device associated with the first working mode, is determined, so as to determine whether the first electronic device has the right to use the target camera module. Specifically, when the first electronic device meets a first preset condition, a target operation corresponding to the first control information may be executed; under the condition that the first electronic device does not meet the first preset condition, the first electronic device may not respond to the first control information, or send the first feedback information to the first electronic device, that is, prohibit the first electronic device from using the target camera module. And the target camera module comprises a plurality of working modes, each working mode is at least associated with one electronic device, and the first working mode is one working mode in the plurality of working modes. Therefore, the situation that any person or any electronic equipment is connected at will and uses the target camera module can be avoided, the target camera module can be used by the illegal user or the electronic equipment except the electronic equipment associated with the first working mode, data leakage in the camera module is avoided, and the safety of the shared camera module (such as a detachable camera module) is improved.
Optionally, the method for controlling a camera module according to the embodiment of the present invention may further include, before the step S101, steps S104 to S107:
and S104, the second electronic equipment sends second control information to the target camera module, and the second control information is used for indicating the working mode of the target camera module to be switched from the second working mode to the first working mode.
The second electronic equipment is the same as or different from the first electronic equipment. That is, any electronic device can initiate the second control information for triggering the target camera module to switch the working mode.
And S105, the target camera module receives second control information sent by the second electronic equipment.
And S106, under the condition that the electronic equipment corresponding to the second working mode is different from the first electronic equipment, the target camera module acquires authentication image information, wherein the authentication image information has biological characteristic information.
The electronic equipment pre-associated with the first working mode is completely or partially different from the electronic equipment pre-associated with the second working mode, and the second working mode is one working mode different from the first working mode in a plurality of working modes of the target camera module.
It is understood that the authentication image information may include biometric information such as face image information or fingerprint image information.
And S107, under the condition that the biological characteristic information accords with the preset biological characteristic information, the target camera module switches the working mode of the target camera module from the second working mode to the first working mode.
For example, the preset biometric information may be face feature information, fingerprint feature information, iris feature information, or the like.
The biometric information in the authentication image information conforms to the preset biometric information, and the similarity of the two pieces of biometric information is greater than or equal to a certain threshold (for example, 70%), which indicates that the biometric information in the authentication image information and the preset biometric information are the biometric information of the same person.
Optionally, in a scenario where the target camera module controls the target camera module to obtain the authentication image information, if the target camera module is connected to the second electronic device (for example, detachably connected), the biometric information in the authentication image information is biometric information of a user using the second electronic device. At this time, the biometric information in the authentication image information acquired by the target camera module conforms to the preset biometric information, which indicates that the user currently using the second electronic device is a preset user with the right to use the target camera module.
If the target camera module is connected with other electronic equipment except the second electronic equipment (for example, detachably connected), the biological characteristic information in the authentication image information is the biological characteristic information of the user using the other electronic equipment. At this time, the biometric information in the authentication image information acquired by the target camera module conforms to the preset biometric information, which indicates that the user currently using the other electronic device is a preset user with the authority to use the target camera module.
In the embodiment of the invention, after the second electronic device initiates the second control information, the target camera module can acquire the biological characteristic information of the user by acquiring the authentication image information in real time, so that the biological characteristic information is compared with the preset biological characteristic information, and whether the second electronic device has the authority to use the target camera module is further judged. Therefore, the safety of the shared camera module is further improved.
Optionally, the second control information carries the first verification information. The camera module control method provided in the embodiment of the present invention, after S105, may further include S108:
and S108, under the condition that the first verification information is matched with the preset verification information, the target camera module switches the working mode of the target camera module from the second working mode to the first working mode.
The preset verification information is the verification information stored in the target camera module in advance.
Specifically, the second verification information is preset verification information in the target camera module, and the second preset verification information is the same as or different from the preset biological characteristic information.
For example, the second verification information may be biometric information such as fingerprint feature information and face feature information, and may also be character information or graphic information, which is not specifically limited in this embodiment of the present invention.
Therefore, after the second electronic device initiates the second control information, the target camera module can judge whether the second electronic device has the authority to trigger the target camera module to switch the working mode by comparing the first verification information in the second electronic device with the preset verification information, and therefore, the safety of sharing the camera module is further improved.
Optionally, in this embodiment of the present invention, the first operating mode and the second operating mode are respectively pre-associated with at least one electronic device, and the electronic device pre-associated with the first operating mode is not identical to the electronic device pre-associated with the second operating mode.
Illustratively, in example 1, the first operating mode is pre-associated with the at least one third electronic device and the second operating mode is pre-associated with the at least one fourth electronic device.
In example 2, the electronic device pre-associated with the first operating mode is any electronic device, and the second operating mode is pre-associated with at least one fifth electronic device. At this time, the first working mode may be a sharing mode of the target camera module, that is, the target camera module may be shared by any electronic device. The second working mode may be a private mode of the target camera module, and the number of the at least one fifth electronic device may be one, that is, the target camera module may be used by the pre-associated fifth electronic device (e.g., the electronic device that triggers the setting of the first working mode or the only fixedly-adapted electronic device).
In example 3, the first operation mode is pre-associated with at least one sixth electronic device, and the electronic device pre-associated with the second operation mode is any electronic device. At this time, the first working mode may be a private mode of the target camera module, and the second working mode may be a sharing mode of the target camera module.
Optionally, the camera module control method provided in the embodiment of the present invention may pre-associate, for a working mode (i.e., a sharing mode) in which the pre-associated electronic device is any electronic device, a usage right with a lower permission level of the target camera module, such as a right for connecting the target camera module and a right for previewing an image acquired by the target camera module. Therefore, under the condition that the target camera module is in the sharing mode, although any electronic equipment can be connected with and use the target camera module, the use permission of the target camera module is low, and the safety of the shared camera module can be improved to a certain extent.
In addition, the camera module control method provided in the embodiment of the present invention may pre-associate, for a working mode (i.e., a private mode) associated with a specific one or more electronic devices in advance, a usage right with a higher permission level of the target camera module, such as a permission to shoot or record through the target camera module. Therefore, under the condition that the target camera module is in the private mode, the user can be ensured to acquire the use permission with higher permission level of the target camera module, more functions of the target camera module are acquired, and the improvement of the use experience of the user for using the target camera module is facilitated.
Optionally, the control information carries second verification information; the first preset condition further includes: the second verification information conforms to third verification information preset in the target camera module.
The third verification information is preset verification information in the target camera module, and the third verification information is the same as or different from the preset biological characteristic information.
It is to be understood that the second authentication information may be authentication information in the first electronic device.
For example, the third verification information may be biometric information such as fingerprint feature information and face feature information, and may also be character information or graphic information.
Therefore, after the first electronic device initiates the first control information, the target camera module can judge whether the first electronic device has the authority to use the target camera module by comparing the second verification information in the first electronic device with the third verification information preset in the target camera module, and therefore the safety of sharing the camera module is further improved.
