For example, air interfaces used by communication systems include, for example, Frequency Division Multiple Access (FDMA), Time Division Multiple Access (TDMA), Code Division Multiple Access (CDMA), and Universal Mobile Telecommunications System (UMTS) (in particular, Long Term Evolution (LTE) ), Global System for Mobile Communications (GSM), etc. As a non-limiting example, the following description refers to a CDMA communication system, but such teachings are equally applicable to other types of systems.

Referring to FIG. 2 , a CDMA wireless communication system may include a plurality of smart terminals 100 , a plurality of base stations (BS) 270 , a base station controller (BSC) 275 and a mobile switching center (MSC) 280 .

Based on the above hardware structure of the smart terminal and the communication system, various embodiments of the method of the present invention are proposed.

Please refer to Fig. 3, which shows the partition of the touch screen of the smart terminal according to the embodiment of the present invention, wherein the area 10 is a common area (abbreviated as area A), which is used to normally receive the user's touch operation and execute corresponding instructions; area 20 It is an edge area (also called preset area, or C area for short) of the borderless touch screen, and is divided into a first edge area 21 and a second edge area 22 .

At present, the camera function can be triggered on the horizontal screen through our company's unique borderless interactive method. photo mode. However, this method currently has disadvantages: after entering the camera mode, it is still the same as the conventional operation, first to focus on the object to be photographed, and to take a photo by clicking the camera button on the touch screen after the focus is completed. Its operation still leaves inconvenient regret. How to quickly realize automatic focus and capture while quickly triggering the camera application is the key point of the breakthrough of the present invention.

As shown in Figure 4, it shows the structure of an embodiment of the trigger camera device embedded in the smart terminal of the present invention. The device includes a horizontal screen holding recognition module 410, a borderless C-zone pressure detection module 420 and a camera application response module connected in sequence. Module 430, in which:

The horizontal screen holding recognition module 410 is used to issue a pressure detection command to the borderless C area pressure detection module 420 after recognizing the landscape holding mode of the smart terminal user;

The pressure detection module 420 in the borderless C area is used to push the pressure parameters detected in the borderless C area to the photographing application response module 430 according to the pressure detection instruction;

The photographing application response module 430 is configured to generate a combined operation mode to trigger photographing according to the received comparison result of the measured pressure parameter and the preset pressure parameter.

As shown in Figure 5, it shows the structure of the pressure detection module in the borderless C area in the device embodiment shown in Figure 4, including the interconnected pressure parameter pushing unit 4201 and pressure sensing unit 4202, wherein:

The pressure parameter pushing unit 4201 is configured to push the pressure intensity and its duration acquired by the pressure sensing unit 4202 to the photographing application response module 430 after receiving the pressure detection instruction;

The pressure sensing unit 4202 is used to detect the pressure intensity and its duration at the corresponding position through the pressure sensitive components arranged in N (N=1,...4) positions of the borderless area C, and output it to the pressure parameter pushing unit 4201 ;

The photographing application response module 430 generates a combined operation mode to trigger photographing according to the result of comparing the measured pressure intensity and its duration at the corresponding location with the preset pressure intensity and its duration.

That is to say, the photographing application response module 430 generates pressure intensity exceeding (including equal to) the predetermined pressure intensity within the predetermined duration according to the corresponding location, or produces different pressures within the predetermined duration according to the corresponding location. The extent to which the strength exceeds the predetermined pressure strength (the magnitude of the difference) corresponds to generating various ways to trigger the photographing. Such as special effects photography, including soft light, dim and black and white, etc., and continuous multi-shot mode and video mode.

In the above device embodiment, the recognition module for holding the screen in landscape orientation determines that the current holding state is the landscape holding mode according to the two touch points in the first edge area 21 and the two touch points in the second edge area.

As shown in Figure 6, it is a bridge structure composed of pressure sensing units 4202 arranged at the four corners of the borderless C area, and a +3V power supply voltage is provided on the smart terminal, and one end of the bridge is grounded . When the pressure-sensitive component is deformed due to unbalanced pressure, the resistance value changes, so that the output voltage value on the two terminals on the right changes significantly. By detecting the change, a pressure change signal is detected, and the pressure The change signal has two parameters, pressure value and duration, which are reported to the application layer through the kernel (driver) layer; after receiving them, the application layer generates different responses according to different scenarios at that time. For example, if it is currently a camera application, when the pressing pressure reaches a certain threshold within a certain period of time, a camera command is generated, and the user does not need to specifically click the camera button to trigger the camera.

The photographing trigger mode provided by the present invention is relatively simple and effective in operation. That is, several pressure sensors (pressure-sensitive diodes) are built in the borderless C area. After the camera application is triggered by holding the horizontal screen, press the four corners of the borderless C area immediately. The pressure threshold is adjustable. If and only When the four (or less than 4) pressure sensors corresponding to the four points held by the horizontal screen detect the pressing of the human hand at the same time, and the pressing force reaches the threshold, it will trigger auto-focus and take pictures.

The embodiment of the method for triggering the camera function embedded in the smart terminal provided by the present invention has the following process steps:

S10: After identifying the horizontal screen holding mode of the smart terminal, detect the pressure parameters of the corresponding positions through the pressure-sensitive components arranged at the N (N=1,...4) corner positions of the borderless C area of the touch screen;

S20: According to the result of comparing the pressure parameter detected at the corresponding position with the preset pressure parameter, a combined operation mode is generated to trigger the photographing.

In the above method embodiment, the borderless area C of the touch screen is the edge area 20 of the borderless touch screen, including the first edge area 21 and the second edge area 22 .

Above-mentioned step S10 specifically comprises:
