Detailed ways

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 by the embodiments set forth herein. Rather, these embodiments are provided so that the present disclosure will be more thoroughly understood, and will fully convey the scope of the present disclosure to those skilled in the art.

Referring to FIG. 1 , a flowchart of steps of a method for activating a camera in a mobile terminal according to an embodiment of the present invention is shown, which may specifically include the following steps:

Step 101: Perform fingerprint verification in the mobile terminal.

It should be noted that the embodiments of the present invention may be applied to mobile terminals, for example, mobile phones, tablet computers, personal digital assistants, wearable devices (such as glasses, watches, etc.), and the like.

The operating system of the mobile device may include Android (Android), IOS, Windows Phone, Windows, etc., which is not limited in this embodiment of the present invention.

In a specific implementation, the mobile terminal may be configured with sensors such as a camera and a fingerprint sensor to perform operations such as shooting, video recording, fingerprint unlocking, and fingerprint payment.

In the embodiment of the present invention, as shown in FIG. 2 , in order to save the area and make the mobile terminal a device with a high screen occupation, such as a full screen, a groove can be set in the cavity of the mobile terminal, so that the camera can be embedded in the mobile terminal in the cavity.

In an example, as shown in FIG. 3A and FIG. 3C , facing the front and back of the mobile terminal 300 , the screen occupies the main area of the front, the physical buttons are cancelled, and virtual buttons can be used for control. In addition, the camera 301 (module) It can be embedded in the cavity of the mobile terminal 301 and does not occupy an area on the front and back, so 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 an opening, and it can be observed that the camera 301 is embedded in the cavity of the mobile terminal 301 and exposed at the opening so as to be pressed into the cavity and removed from the cavity. Cavity pops out.

It should be noted that, because the mobile terminal may be a single screen or two screens, for example, one of them is the main screen, and a high-resolution (1280*720, 1920x1080) screen is usually configured, such as TFT (Thin FilmTransistor, thin film) Transistor) LCD screen, etc., arranged on the front of the mobile terminal. The other is a secondary screen, usually a low-resolution (such as 480x320, 640x480) screen, such as a TFT LCD screen, an ink screen, etc., is set on the back of the mobile terminal and can be used to assist in displaying various states of the mobile terminal, including Battery life, contacts, unread text messages, missed calls, display dial pad, weather information, e-book reading, and more.

Therefore, the mobile terminal may embed a front camera, a rear camera, or a front camera and a rear camera at the same time, which is not limited in this embodiment of the present invention.

In addition, as shown in FIG. 3C , the fingerprint sensor 302 can be installed on the back of the mobile terminal 300 . Of course, when the ink screen is installed on the back of the mobile terminal, the fingerprint sensor can also be installed on the side of the mobile terminal.

By applying the embodiment of the present invention, the user's original fingerprint data can be recorded in the fingerprint sensor in advance as a sample to be matched later.

When calling the camera, the target fingerprint data can be collected by the fingerprint sensor, and the previously entered original sample data can be extracted for matching.

The matching between the original fingerprint data and the target fingerprint data is identified by comparing the minutiae feature points of different fingerprints, which usually includes processes such as preprocessing, feature extraction, and comparison.

1. Preprocessing;

Usually, it can include fingerprint area detection, image quality judgment, orientation map and frequency estimation, image enhancement, fingerprint image binarization and refinement, etc.

3. Feature extraction;

The morphological features of fingerprints include center (up, down) and triangular points (left, right), etc. The detailed feature points of fingerprints mainly include the starting point, end point, joint point and bifurcation point of the ridge.

4. Comparison;

The rough matching can be carried out according to the pattern of the fingerprint, and then the fingerprint shape and detail features can be used for precise matching, and the similarity score between the original fingerprint data and the target fingerprint data can be obtained.

Depending on the application, sort the similarity scores of the fingerprints or give a judgment result of whether they are the same fingerprint.

Step 102, when the fingerprint verification is successful, eject the camera from the cavity of the mobile terminal to the outside of the cavity of the mobile terminal, and start the camera application.

When the mobile terminal is unlocked and the screen is bright, if the fingerprint verification is successful, the camera can be ejected from the cavity of the mobile terminal by mechanical means (such as a pop-up device combined with an electronic lock and an elastic pressure device), and the camera application can be started. Realize the startup of the camera.

As shown in FIG. 3D , the camera 301 pops up into the cavity of the mobile terminal 300 , and can directly face external things, and the user can use the camera to normally perform operations such as photographing and video recording.

After taking pictures, videos, etc., you can close the camera application.

When the camera application is closed, the camera is retracted from the cavity of the mobile terminal into the cavity of the mobile terminal, so as to close the camera.

In a specific implementation, the operations of popping up and retracting the camera are generally coordinated through various levels of the operating system.

For example, in the Android system, running an application (such as a camera application) generally requires Java applications (application layer), Framework (application framework layer, that is, the middle layer), Hardware (hardware abstraction layer), and Linux Kernel (Linux kernel layer). interaction between.

The camera application corresponding to the camera can pre-register the verification event, if the fingerprint verification service reports the verification event to the application layer.

In this embodiment of the present invention, the camera application may reside in the memory and monitor the verification event in real time.

It should be noted that, in addition to the camera application, other applications can also register to listen to the verification event, such as unlocking applications, payment applications, etc. However, these applications may not be started, and may not have listened to the verification event, or, due to different environments Matching and other factors, related applications (such as lock screen applications, payment applications) will not respond to verification events.

In the camera, a pop-up event can be pre-defined to pop up the camera. If the camera application is listening to a verification event, the verification event can be mapped to a pop-up event.
