Detailed Description
Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
Referring to fig. 1, a flowchart illustrating steps of a method for starting a camera in a mobile terminal according to an embodiment of the present invention may specifically include the following steps:
It should be noted that the embodiments of the present invention may be applied to a mobile terminal, for example, a mobile phone, a tablet computer, a personal digital assistant, a wearable device (such as glasses, a watch, and the like), and the like.
The operating system of the mobile device may include Android (Android), IOS, Windows Phone, Windows, and the like, which is not limited in this embodiment of the present invention.
In specific implementation, the mobile terminal may be configured with a camera, a fingerprint sensor, and other sensors to perform operations such as shooting, recording, fingerprint unlocking, fingerprint payment, and the like.
In the embodiment of the present invention, as shown in fig. 2, in order to save area and enable the mobile terminal to become a device with a higher screen occupation, such as a full screen, a cavity of the mobile terminal may be provided with a groove, so that the camera may be embedded in the cavity of the mobile terminal.
In one example, as shown in fig. 3A and 3C, facing the front and back of the mobile terminal 300, the screen occupies a major area of the front, the physical keys are canceled, virtual keys can be used for control, and furthermore, the camera 301 (module) can be embedded in the cavity of the mobile terminal 301, not occupying area on the front and back, and thus the camera 301 cannot be seen on the front and back.
As shown in fig. 3B, facing the upper side of the mobile terminal 300, the mobile terminal 300 has a head where the camera 301 is seen to be embedded in the cavity of the mobile terminal 301, and exposed at the head so as to be pressed into and ejected from the cavity.
Note that, since the mobile terminal may be a single screen or two screens, for example, one of the screens is a main screen, and a screen configured with high resolution (1280 × 720, 1920 × 1080), such as a Thin Film Transistor (TFT) liquid crystal screen, is disposed on the front side of the mobile terminal. And the other is a sub-screen, generally configured with a low-resolution (e.g. 480x320, 640x480) screen, such as a TFT liquid crystal screen, an ink screen, and the like, arranged on the back of the mobile terminal, and may be used to assist in displaying various states of the mobile terminal, including endurance, contacts, unread messages, missed calls, display of a dial-up keypad, weather information, e-book reading, and the like.
Therefore, the mobile terminal may be embedded with a front-facing camera, a rear-facing camera, or both the front-facing camera and the rear-facing camera, which is not limited in the embodiments of the present invention.
Further, as shown in fig. 3C, the fingerprint sensor 302 may be mounted on the back of the mobile terminal 300, but of course, in the case where an ink screen is mounted on the back of the mobile terminal, the fingerprint sensor may be mounted on the side of the mobile terminal.
By applying the embodiment of the invention, the original fingerprint data of the user can be input in advance through the fingerprint sensor and used as a sample for later matching.
When the camera is called, target fingerprint data can be collected through the fingerprint sensor, and the previously input original sample data is extracted for matching.
The matching of the original fingerprint data and the target fingerprint data is identified by comparing the minutiae of different fingerprints, and generally comprises the processes of preprocessing, feature extraction, comparison and the like.
1. Pre-treating;
fingerprint region detection, image quality judgment, direction diagram and frequency estimation, image enhancement, fingerprint image binarization and refinement and the like can be generally included.
3. Extracting characteristics;
the fingerprint morphological characteristics comprise a center (upper and lower), triangular points (left and right) and the like, and the minutiae characteristic points of the fingerprint mainly comprise a starting point, an end point, a combination point and a bifurcation point of a ridge line.
4. Comparing;
the method can perform rough matching according to the fingerprint shape, further perform accurate matching by using the fingerprint shape and the detail characteristics, and give a similarity score of the original fingerprint data and the target fingerprint data.
According to different applications, the similarity scores of the fingerprints are sorted or a judgment result of whether the fingerprints are the same is given.
And 102, popping the camera out of the cavity of the mobile terminal from the cavity of the mobile terminal when the fingerprint verification is successful, and starting the camera application.
Under the states of unlocking and screen lighting of the mobile terminal and the like, if the fingerprint verification is successful, the camera can be popped out from the cavity of the mobile terminal through a mechanical mode (such as a popping device combining an electronic lock and a popping device), the application of the camera is started, and the starting of the camera is realized.
As shown in fig. 3D, the camera 301 is popped out of the cavity of the mobile terminal 300, and can directly face to an external object, so that a user can use the camera to perform operations such as photographing and recording.
If the operations such as photographing and recording are finished, the camera application can be closed.
When the camera is closed, the camera is retracted into the cavity of the mobile terminal from the outside of the cavity of the mobile terminal, and the camera is closed.
In a particular implementation, the operations of ejecting and retracting the camera are generally coordinated through various levels of the operating system.
For example, in the Android system, running an application (e.g., a camera application) generally requires interaction between Java applications (application layer), Framework (application Framework layer, i.e., middle layer), Hardware (Hardware abstraction layer), and Linux Kernel (Linux Kernel layer).
In one embodiment of the present invention, step 102 may include the following sub-steps:
a sub-step S11, generating a verification event that the fingerprint verification succeeds by the fingerprint verification service in the middle layer;
substep S12, the fingerprint verification service maps the verification event into a pop-up event and reports the pop-up event to an application layer;
a substep S13 of starting a camera application registered with the pop-up event in the application layer;
and a substep S14, driving an ejection device located on a hardware layer by the camera application according to the ejection event, and ejecting the camera from the cavity of the mobile terminal to the outside of the cavity of the mobile terminal.
In the mobile terminal, the fingerprint authentication service of the fingerprint sensor generates an authentication event, i.e., an event indicating that the fingerprint authentication is successful, after the fingerprint authentication is successful.
In order to improve the security of the mobile terminal, corresponding events may be defined in the fingerprint sensor, and the authentication events may be mapped to these events and provided to the relevant application calls.
In the embodiment of the invention, the events defined by the fingerprint sensor comprise pop-up events, namely, the events representing the pop-up of the camera, and the verification events are mapped into the pop-up events and then reported to the application layer.
It should be noted that, besides the pop-up event, the fingerprint sensor may also define other events, and may map the verification event to these events, for example, an unlocking event, a payment event, and the like, and these events may also be reported to the application layer, but due to factors such as environment mismatch, the relevant applications (such as the screen locking application and the payment application) may not respond to the relevant events such as the unlocking event and the payment event.
The camera application corresponding to the camera can register the pop-up event in advance, and if the fingerprint verification service reports the pop-up event to the application layer, the camera application can monitor the pop-up event.
In the embodiment of the invention, the camera is connected with the ejection device, and the camera application can drive the ejection device positioned on the hardware layer to eject the camera from the cavity of the mobile terminal to the outside of the cavity of the mobile terminal.
In another embodiment of the present invention, step 102 may include the following sub-steps:
a substep S21, generating a verification event of successful fingerprint verification in the fingerprint verification service in the middle layer and reporting the verification event to the application layer;
a substep S22, receiving the verification event by the camera application at the application layer;
substep S23, mapping the verification event to a pop-up event by the camera application;
and a substep S24, driving an ejection device located on a hardware layer by the camera application according to the ejection event, and ejecting the camera from the cavity of the mobile terminal to the outside of the cavity of the mobile terminal.
In the mobile terminal, after the fingerprint verification service of the fingerprint sensor successfully verifies the fingerprint, a verification event is generated, namely the event representing the successful fingerprint verification is reported to an application layer.
The camera application corresponding to the camera can register a verification event in advance, and if the fingerprint verification service reports the verification event to the application layer.
In the embodiment of the invention, the camera application can reside in the memory and can monitor the verification event in real time.
It should be noted that, besides the camera application, other applications may also register and listen to the verification event, for example, an unlock application, a payment application, etc., but these applications may not be started, not listen to the verification event, or related applications (e.g., a lock screen application, a payment application) may not respond to the verification event due to factors such as environmental mismatch.
In the camera, a pop-up event may be predefined to pop up the camera, and if the camera application monitors the verification event, the verification event may be mapped to the pop-up event.
In the embodiment of the invention, the camera is connected with the ejection device, and the camera application can drive the ejection device positioned on the hardware layer to eject the camera from the cavity of the mobile terminal to the outside of the cavity of the mobile terminal.
In one embodiment of the present invention, step 102 may include the following sub-steps:
a substep S31, generating a verification event that the fingerprint verification is successful in the fingerprint verification service in the middle layer;
in the substep S32, calling a pre-packaged interface in the middle layer according to the verification event, driving a pop-up device located in the hardware layer, and popping up the camera from the cavity of the mobile terminal to the outside of the cavity of the mobile terminal;
a substep S33 of generating an interrupt signal when the camera is ejected;
and a substep S34 of starting the camera application at the application layer according to the interrupt signal.
In the mobile terminal, the fingerprint authentication service of the fingerprint sensor generates an authentication event, i.e., an event indicating that the fingerprint authentication is successful, after the fingerprint authentication is successful.
In addition, interfaces can be packaged in advance for the convenience of popping up the camera, and the interfaces can be a Hardware abstraction layer (Hardware abstraction layer) interface function library of Hardware (such as the camera) provided by the system platform and used for upper layer calling.
Therefore, the function library can directly drive the ejection device positioned on the hardware layer to eject the camera from the cavity of the mobile terminal to the outside of the cavity of the mobile terminal.
When the camera is popped up, an interrupt signal can be generated, so that the processor can be interrupted to start the camera application.
The camera is embedded in the cavity of the mobile terminal, when the fingerprint verification in the mobile terminal is successful, the camera is popped out of the cavity of the mobile terminal from the cavity of the mobile terminal, and the camera application is started.

The terminal may be any terminal device including a mobile phone, a tablet computer, a PDA (Personal Digital Assistant), a POS (Point of Sales), a vehicle-mounted computer, etc., taking the terminal as the mobile phone as an example:
fig. 5 is a block diagram illustrating a partial structure of a mobile phone related to a terminal provided in an embodiment of the present invention.

Those skilled in the art will appreciate that the handset configuration shown in fig. 5 is not intended to be limiting and may include more or fewer components than those shown, or some components may be combined, or a different arrangement of components.
The following describes each component of the mobile phone in detail with reference to fig. 5:
The memory 520 may be used to store software programs and modules, and the processor 580 executes various functional applications and data processing of the mobile phone by operating the software programs and modules stored in the memory 520. The memory 520 may mainly include a program storage area and a data storage area, wherein the program storage area may store an operating system, an application program required by at least one function (such as a sound playing function, an image playing function, etc.), and the like; the storage data area may store data (such as audio data, a phonebook, etc.) created according to the use of the cellular phone, and the like. Further, the memory 520 may include high speed random access memory, and may also include non-volatile memory, such as at least one magnetic disk storage device, flash memory device, or other volatile solid state storage device.
The input unit 530 may be used to receive input numeric or character information and generate key signal inputs related to user settings and function control of the cellular phone. Specifically, the input unit 530 may include a touch panel 531 and other input devices 532. The touch panel 531, also called a touch screen, can collect touch operations of a user on or near the touch panel 531 (for example, operations of the user on or near the touch panel 531 by using any suitable object or accessory such as a finger or a stylus pen), and drive the corresponding connection device according to a preset program. Alternatively, the touch panel 531 may include two parts, a touch detection device and a touch controller. The touch detection device detects the touch direction of a user, detects a signal brought by touch operation and transmits the signal to the touch controller; the touch controller receives touch information from the touch sensing device, converts the touch information into touch point coordinates, and sends the touch point coordinates to the processor 580, and can receive and execute commands sent by the processor 580. In addition, the touch panel 531 may be implemented by various types such as a resistive type, a capacitive type, an infrared ray, and a surface acoustic wave. The input unit 530 may include other input devices 532 in addition to the touch panel 531.

The display unit 540 may be used to display information input by the user or information provided to the user and various menus of the mobile phone. The Display unit 540 may include a Display panel 541, and optionally, the Display panel 541 may be configured in the form of a Liquid Crystal Display (LCD), an Organic Light-Emitting Diode (OLED), or the like. Further, the touch panel 531 may cover the display panel 541, and when the touch panel 531 detects a touch operation on or near the touch panel 531, the touch panel is transmitted to the processor 580 to determine the type of the touch event, and then the processor 580 provides a corresponding visual output on the display panel 541 according to the type of the touch event. Although the touch panel 531 and the display panel 541 are shown as two separate components in fig. 5 to implement the input and output functions of the mobile phone, in some embodiments, the touch panel 531 and the display panel 541 may be integrated to implement the input and output functions of the mobile phone.

Specifically, the fingerprint sensor may collect fingerprint data, and the light sensor may include an ambient light sensor and a proximity sensor, where the ambient light sensor may adjust brightness of the display panel 541 according to brightness of ambient light, and the proximity sensor may turn off the display panel 541 and/or backlight when the mobile phone moves to an ear. As one of the motion sensors, the accelerometer sensor can detect the magnitude of acceleration in each direction (generally, three axes), can detect the magnitude and direction of gravity when stationary, and can be used for applications of recognizing the posture of a mobile phone (such as horizontal and vertical screen switching, related games, magnetometer posture calibration), vibration recognition related functions (such as pedometer and tapping), and the like; as for other sensors such as a gyroscope, a barometer, a hygrometer, a thermometer, and an infrared sensor, which can be configured on the mobile phone, further description is omitted here.
WiFi belongs to short distance wireless transmission technology, and the mobile phone can help the user to send and receive e-mail, browse web pages, access streaming media, etc. through the WiFi module 570, which provides wireless broadband internet access for the user. Although fig. 5 shows the WiFi module 570, it is understood that it does not belong to the essential constitution of the handset, and can be omitted entirely as needed within the scope not changing the essence of the invention.
The processor 580 is a control center of the mobile phone, connects various parts of the entire mobile phone by using various interfaces and lines, and performs various functions of the mobile phone and processes data by operating or executing software programs and/or modules stored in the memory 520 and calling data stored in the memory 520, thereby performing overall monitoring of the mobile phone. Alternatively, processor 580 may include one or more processing units; preferably, the processor 580 may integrate an application processor, which mainly handles operating systems, user interfaces, application programs, etc., and a modem processor, which mainly handles wireless communications. It will be appreciated that the modem processor described above may not be integrated into processor 580.
The handset also includes a power supply 590 (e.g., a battery) for powering the various components, which may preferably be logically coupled to the processor 580 via a power management system, such that the power management system may be used to manage charging, discharging, and power consumption.
