Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

As shown in FIG. 1, a display control method according to an embodiment of the present invention includes:

Step 101: Obtain the real-time distance between the face of the mobile terminal operator and the display screen of the mobile terminal.

In this step, the mobile terminal applying the display control method of the embodiment of the present invention will provide a basis for the next control by obtaining the real-time distance between the display screen of the mobile terminal and the face of the operator operating the mobile terminal.

Step 102: Based on the real-time distance, adjust the display scale of the target object displayed on the display screen of the mobile terminal.

In this step, after the real-time distance between the display screen and the operator's face is acquired in step 101, the user's viewing requirements for the target object can be learned according to the real-time distance, and corresponding control operations can be performed to facilitate the user Check.

Through the above steps 101 and 102, the display control method of the embodiment of the present invention first acquires the real-time distance between the display screen of the mobile terminal and the face of the operator who operates the mobile terminal; and then adjusts the target based on the real-time distance. The display scale of the object displayed on the display screen, and the corresponding zoom-in or zoom-in operation is performed to complete the viewing required by the user. Since the adjustment of the display ratio of the target object is mainly based on the real-time distance between the display screen and the operator's face, it can be applied to more scenarios, effectively solving the limitations of the existing manual zoom control operation, and improving the mobile terminal. ease of use.

It should be known that, for the mobile terminal to which the display control method of the embodiment of the present invention is applied, if the distance between the display screen and the operator's face is continuously acquired, resources will be wasted. Therefore, it will only take effect when the current display content of the display screen has a zoom requirement. Preferably, the mobile terminal will confirm the current display content of the display screen. If the current display content is a preset application type with zoom requirements , the above steps 101 and 102 will be executed; otherwise, the above steps will not be executed.

Among them, the preset application type with zoom requirements may be a picture, a map, or a news application. Because these application types sometimes need to be enlarged in order to see a certain detail more clearly, they are often defined as application types with zoom requirements. For music players, application malls or game malls, etc., since there are no scenarios that need to be scaled, they will not be defined as application types with scaling requirements.

When the currently displayed content is a preset application type with scaling requirements, as shown in FIG. 1 , the adjustment of the display scale of the target object is implemented according to steps 101 and 102. In order to obtain a more accurate distance, specifically, step 101 includes:

Carry out facial recognition to the operator by the structured light module of the mobile terminal, and after recognizing the face, obtain the real-time distance between the operator's face and the display screen.

The structured light module of the mobile terminal includes two parts: an infrared transmitter and an infrared camera. Here, the infrared transmitter emits infrared light with a specific pattern, which is reflected on the surface of the object. After receiving the reflected infrared light pattern, the infrared camera can analyze and calculate the distance between the object and the mobile terminal. The infrared camera can also perform facial recognition on objects. Therefore, the real-time distance obtained by the structured light module can be determined as the real-time distance between the operator's face and the display screen, avoiding errors due to other obstructions.

After the real-time distance is obtained, the display scale of the target object can be adjusted based on the real-time distance. Preferably, step 102 includes:

detecting the change information of the real-time distance;

According to the change information, determine the scale adjustment parameter of the target object;

According to the scale adjustment parameter, the display scale of the target object displayed on the display screen of the mobile terminal is adjusted.

In this embodiment, after the structured light module is turned on, the real-time detected distance between the display screen and the operator's face can be obtained through the structured light module. Therefore, the corresponding real-time distance can be further detected. Then, the scale adjustment parameter of the target object is specified by the change information, and according to the scale adjustment parameter, the display scale of the target object displayed on the display screen of the mobile terminal is adjusted, and the target object is reduced or enlarged to display.

Wherein, since the change is relative, in order to better understand the change of the distance, in the above embodiment, the step of detecting the change information of the real-time distance includes:

obtaining the initial distance between the operator's face and the display screen;

determining the initial distance as a reference distance;

Change information of the real-time distance relative to the reference distance is detected.

Here, the initial distance between the operator's face and the display screen is obtained first, and then the obtained initial distance is determined as the reference distance, and then the change information of the real-time distance relative to the reference distance can be detected to obtain a more precise change information. Among them, the initial distance is usually the distance between the first display screen and the operator's face obtained after enabling the structured light module.

However, considering that in practical applications, the distance will change in many scenarios. For example, when browsing pictures, the user may directly put the mobile terminal on the desktop due to other things. Zoom out or zoom in. If it is determined to reduce or enlarge the target object simply according to the increase or decrease of the distance, it cannot meet the actual application requirements. Therefore, in this embodiment of the present invention, preferably, the mobile terminal will perform corresponding operations by judging that an event in which the distance changes rapidly and returns to the reference distance quickly occurs.

Therefore, the change information includes: the change direction of the real-time distance relative to the reference distance, the time when the absolute difference between the real-time distance and the reference distance increases to a preset threshold value, and the The maximum value of the absolute difference.

The change direction of the real-time distance relative to the reference distance refers to whether the real-time distance increases or decreases compared with the reference distance. If the operator is farther from the display screen of the mobile terminal than the reference distance, the change direction is determined to be increasing. ; If the author is closer to the display screen of the mobile terminal than the reference distance, the change direction is determined to be decreasing. And in the process of returning to the reference distance, considering that human beings cannot achieve complete accuracy, a preset threshold value is also set to avoid misjudgment, the preset threshold value is not a specific value, preferably a range value.

Further, the described proportional adjustment parameter, the step of adjusting the display ratio of the target object displayed on the display screen of the mobile terminal, includes:

If the time is less than the preset time, and the change direction indicates that the change of the real-time distance relative to the reference distance is to increase first and then decrease, then the first display scale corresponding to the maximum value of the absolute difference will be used. , the target object is enlarged and displayed;

If the time is less than the preset time, and the change direction indicates that the change of the real-time distance relative to the reference distance first decreases and then increases, then the second display scale corresponding to the maximum value of the absolute difference will be used. to display the target object in a reduced size.

In this way, when the time in the change information is less than the preset time period, it can be determined that an event in which the distance changes rapidly and returns to the reference distance quickly, and it is necessary to adjust the display scale of the target object and perform zoom-in or zoom-out operations. And the corresponding relationship between different display ratios and the maximum value of the absolute difference is preset in the mobile terminal, and the display ratio to be used is determined by the maximum value of the absolute difference in the change information. When the change direction indicates that the change of the distance relative to the reference distance is to increase first and then decrease, the target object will be enlarged and displayed according to the first display scale corresponding to the maximum value of the absolute difference in the change information; When the change of the distance relative to the reference distance is to decrease first and then increase, the target object is displayed in a reduced size according to the second display ratio corresponding to the maximum value of the absolute difference.

Of course, in order to distinguish the reduction ratio and the enlargement ratio, it is necessary to determine the respective display ratios in the corresponding reduction ratio preset relationship or enlargement ratio preset relationship according to the change direction.

For example, user A operates a mobile terminal to browse pictures, because the picture is a preset application type with scaling requirements, therefore, as shown in Figure 2:

In step 201, the operator (user A) will be recognized by the structured light module of the mobile terminal, and the real-time distance between the operator's face and the display screen will be obtained.

Step 202, determining the obtained initial distance as the reference distance.

When the structured light module is turned on, the detected distance between the first display screen and the operator's face is L1 as shown in Figure 3.

Step 203: Determine the change information of the real-time distance relative to the reference distance.

The opened structured light module detects the distance between user A's face and the display screen in real time when browsing pictures, and obtains change information relative to the reference distance determined in step 202, the change information includes: the change direction of the real-time distance relative to the reference distance, the real-time distance The time for the absolute difference from the reference distance from increasing to decreasing to the preset threshold, and the maximum value of the absolute difference.

Step 204, if the time is less than the preset duration, and the change direction indicates that the change of the real-time distance relative to the reference distance is to increase first and then decrease, then according to the display ratio corresponding to the maximum value of the absolute difference, the target object is enlarged and displayed; if When the time is less than the preset time length, and the change direction indicates that the change of the real-time distance relative to the reference distance first decreases and then increases, the target object is displayed in a reduced size according to the display ratio corresponding to the maximum value of the absolute difference.

Through the change information, knowing that the time is less than the preset time length, it can be determined that the event that the distance changes rapidly and quickly returns to the reference distance, and then combines the change direction and the maximum value of the absolute difference to complete the target object. Operate accordingly. Assuming that the change of the real-time distance relative to the reference distance is to increase first and then decrease, and as shown in Fig. 4, the farthest distance between the face of user A and the display screen is L2, then by |L2-L1| The corresponding display ratio is determined in the setting relationship, and then the picture is enlarged according to the display ratio. Assuming that the change of the distance relative to the reference distance is to decrease first and then increase, and as shown in Figure 5, the closest distance between the face of user A and the display screen is L3, then the relationship between |L3-L1| is preset in the reduction ratio Determine the corresponding display ratio in the , and then reduce the picture according to the display ratio.

In addition, in this embodiment of the present invention, the mobile terminal can also perform corresponding operations by judging that a distance change occurs and an event that triggers a zoom instruction. Therefore, before the step of determining the scale adjustment parameter of the target object according to the change information, it also includes:

Detect whether a zoom command is received;

If the zoom instruction input by the user is received, the step of determining the scale adjustment parameter of the target object according to the change information is performed.

The change information includes: the change direction of the real-time distance relative to the reference distance, and the maximum value of the absolute difference between the real-time distance and the reference distance.

In this way, when the zoom command is received and it is learned that the user has a zoom requirement for the target object, the corresponding adjustment will be made according to the change direction of the real-time distance relative to the reference distance and the maximum value of the absolute difference between the real-time distance and the reference distance. operate. Wherein, in order to facilitate user input, the triggering method of the zoom instruction can be the touch of the operator's finger on the display screen, or the pressing of a virtual key or a physical key (such as a fingerprint identification key arranged on the front, side or back of the mobile terminal) ) and so on, which will not be repeated here.

Further specifically, the step of adjusting the parameter according to the ratio to adjust the display ratio of the target object displayed on the display screen of the mobile terminal includes:

When the change direction indicates that the change of the real-time distance relative to the reference distance is an increase, the target object is enlarged and displayed according to the third display scale corresponding to the maximum value of the absolute difference;

When the change direction indicates that the change of the real-time distance relative to the reference distance is decreasing, the target object is displayed in a reduced size according to a fourth display scale corresponding to the maximum value of the absolute difference.

In this way, after receiving the zoom command, the display scale to be used can be determined from the maximum value of the absolute difference value in the change information based on the corresponding relationship between different display scales preset in the mobile terminal and the maximum value of the absolute difference value. . Then, when the change direction indicates that the change of the real-time distance relative to the reference distance is increasing, the target object is enlarged and displayed according to the third display ratio corresponding to the maximum value of the absolute difference; the change direction indicates that the change of the real-time distance relative to the reference distance In order to reduce, the target object is displayed in a reduced size according to the fourth display ratio corresponding to the maximum value of the absolute difference. Similarly, in order to distinguish the reduction and enlargement ratios, it is necessary to determine the respective display ratios in the corresponding reduction ratio preset relationship or enlargement ratio preset relationship according to the change direction.

For example, user B operates the mobile terminal to browse the map, because the map is a preset application type with zooming requirements, therefore, as shown in Figure 6:

In step 601, the operator (user B) will be recognized by the structured light module of the mobile terminal, and the real-time distance between the operator's face and the display screen will be obtained.

Step 602, determining the obtained initial distance as the reference distance.

The detected distance between the first display screen and the operator's face when the structured light module is turned on.

Step 603: Determine the change information of the real-time distance relative to the reference distance.

The opened structured light module detects the distance between user B's face and the display screen in real time when user B browses the map, and obtains change information relative to the reference distance determined in step 602. The change information includes: the change direction of the real-time distance relative to the reference distance, the real-time distance The maximum value of the absolute difference from the reference distance.

Step 604, when receiving the zoom instruction input by the user, when the change direction indicates that the change of the real-time distance relative to the reference distance is increasing, the target object is enlarged and displayed according to the display ratio corresponding to the maximum value of the absolute difference; Indicates that when the change of the real-time distance relative to the reference distance is decreasing, the target object is displayed in a reduced size according to the display scale corresponding to the maximum value of the absolute difference.

After receiving the zoom command, it can be understood that the user has the zoom requirement for the map, and then the corresponding operation on the target object will be completed in combination with the change direction in the change information and the maximum value of the absolute difference. Assuming that the change of the real-time distance relative to the reference distance is an increase, that is, the position of user B's face is farther from the display screen than the reference distance, then the corresponding display scale is determined from the maximum value of the absolute difference in the change information in the preset magnification scale relationship, The map is then enlarged according to the display scale. Assuming that the change of the real-time distance relative to the reference distance is reduced, that is, the position of user B's face is closer to the display screen than the reference distance, then the corresponding display scale is determined by the maximum value of the absolute difference in the change information in the reduction scale preset relationship, Then zoom out the map according to the display scale.

It should also be known that, in the above embodiments, the target object to be reduced or enlarged mostly refers to the currently displayed content. However, what the user needs may only be the reduction or enlargement of a certain part. Therefore, on the basis of the above embodiment, before the step of determining the scale adjustment parameter of the target object according to the change information, include:

Detect the user's touch operation in the display screen;

If a touch operation is detected, obtaining the operation position of the touch operation;

According to the current display content of the display screen, detect whether the operation position is located in the display area of the display component;

If the operating position is located in the display area of the display component, then the display component is determined as the target object;

If the operation position is not located in the display area of the display component, the current display content is determined as the target object.

In this way, when the operator's touch operation on the display screen is detected, it is possible to detect whether the operation position is located in the display area of the display component by acquiring the operation position of the operation on the display screen and combining with the current display content of the display screen, Further, when the operation position is located in the display area of the display component, the display component is determined as the target object; if the operation position is not located in the display area of the display component, the current display content is determined as the target object. Afterwards, corresponding operations are performed on the determined target object according to the change information.

Among them, the size and coordinates of the display component in the current display content are often pre-defined by the developer, and the system can obtain these data information, so when obtaining the operation position touched by the operator, it can be determined whether the operation position corresponds to the display component or not. Determines whether the operation position is within the display area of the display component within the coordinate range of . Of course, the above steps of determining the target object are in no particular order with obtaining the change information of the real-time distance. The change information can be obtained first and then the target object can be determined, or the target object can be determined first and then the change information can be obtained. Here No longer.

Generally speaking, the selection instruction may also be triggered simultaneously when the above-mentioned user touches the display screen to trigger the zoom instruction.

For example, user C operates the mobile terminal to browse the news application, because the news application is a preset application type with scaling requirements, so as shown in Figure 7:

In step 701, the operator (user C) will be recognized by the structured light module of the mobile terminal, and the real-time distance between the operator's face and the display screen will be obtained.

Step 702: Determine the obtained initial distance as the reference distance.

The detected distance between the first display screen and the operator's face when the structured light module is turned on.

Step 703: Determine the change information of the real-time distance relative to the reference distance.

The opened structured light module detects the distance between user C's face and the display screen when user C browses the news application in real time, and obtains change information relative to the reference distance determined in step 702, and the change information includes: the change direction of the real-time distance relative to the reference distance, the real-time The maximum value of the absolute difference between the distance and the reference distance.

Step 704, when receiving the zoom command input by the user, obtain the trigger position of the command on the display screen (that is, the user's operation position); according to the current display content of the display screen, detect whether the trigger position is located in the display area of the display component; If the trigger position is located in the display area of the display component, the display component is determined as the target object; if the trigger position is not located in the display area of the display component, the current display content is determined as the target object.

Assuming that the coordinates of user C's finger touch are (80, 90), and the starting coordinates of the area where a certain piece of news in the news application is located is (60, 70), the length of the area displayed by the news is 100 and the width is 40, it can be determined that The area that the finger touches is the news item, and the target object to be zoomed is the news. If the coordinates touched by the user's finger are (10, 20), it is determined that the finger touched is the common area of all news, and the target object to be zoomed is the content of the entire news application interface currently displaying the content.

Step 705, when the change direction indicates that the change of the real-time distance relative to the reference distance is increased, the target object is enlarged and displayed according to the display ratio corresponding to the maximum value of the absolute difference; the change direction indicates that the change of the real-time distance relative to the reference distance is: When reducing, the target object is displayed in a reduced size according to the display ratio corresponding to the maximum value of the absolute difference.

Based on the target object determined in step 704, the change of the real-time distance relative to the reference distance is an increase, that is, the position of the face of user C is farther from the display screen than the reference distance, then the maximum value of the absolute difference in the change information is preset in the magnification ratio The corresponding display ratio is determined in the relationship, and then the target object (the content of the news or the entire news application interface) is enlarged according to the display ratio. Assuming that the change of the real-time distance relative to the reference distance is reduced, that is, the position of the face of the user C is closer to the display screen than the reference distance, then the corresponding display scale is determined by the maximum value of the absolute difference in the change information in the reduction scale preset relationship, Then the target object (the news or the content of the entire news application interface) is reduced according to the reduction ratio.

To sum up, in the display control method of the embodiment of the present invention, firstly, the real-time distance between the face of the mobile terminal operator and the display screen of the mobile terminal is obtained; then, based on the real-time distance, the target displayed on the display screen of the mobile terminal is adjusted. The display scale of the object to complete the viewing required by the user. Since the adjustment of the display ratio of the target object is mainly based on the real-time distance between the display screen and the operator's face, it can be applied to more scenarios, effectively solving the limitations of the existing manual zoom control operation, and improving the mobile terminal. ease of use.
