In this embodiment, a screen display control method running on the mobile terminal is provided. FIG. 2 is a flowchart of a screen display control method according to an embodiment of the present invention. As shown in FIG. 2, the flow includes the following steps:

Step S202, acquiring a first position of the face image in the terminal screen;

Step S204, controlling the display screen in the terminal screen to move to the second position according to the relative position of the first position and the reference position of the face image in the terminal screen.

Through the above steps, according to the obtained first position of the face image in the terminal screen and the reference position of the face image, the moving position of the display screen in the terminal screen is controlled, which solves the problem that the user has one-hand operation screen in the related art. Each interface needs to be customized separately, and it cannot cover all the interfaces, which improves the convenience of one-handed operation.

Set the scale to perform compression movement.

Based on the foregoing embodiments and preferred embodiments, in order to explain the entire process interaction of the solution, in the preferred embodiment, a screen display control method is provided. In the method, the terminal uses a mobile phone as an example for description.

Users need to control the mobile phone with one hand in many occasions. According to the conventional holding habit, the mobile phone screen is touched with a thumb. Since the length of the thumb is limited, it is relatively easy to touch the middle area of the screen of the mobile phone, and the edge area of the screen of the mobile phone is often inaccessible or needs to be changed to be touched.

If the content of the edge area that the user wants to touch is automatically moved to the middle area of the mobile phone, the user only needs to click the middle area to complete the operation, which greatly improves the convenience of manipulation.

According to the one-hand control habit, when the user wants to click on the edge area farther from the tip of the thumb, the phone will be slightly tilted on the original plane, so that the area is slightly close to itself, which is equivalent to shortening the distance between the area and the tip of the thumb. For example, if you want to click on the top left corner of your phone, you will turn to the top left corner. The change of the plane of the mobile phone relative to the face of the user can be The judgment is made by the face picture captured by the front camera. That is, the user wants to touch an edge area, and while the area is slightly turned to himself, the face image captured by the front camera also gradually moves toward the area. The intuitive embodiment is to turn on the proactive preview. When you turn a certain edge area to yourself, the face in the preview image will move smoothly to the area. When the movement exceeds a certain threshold, it can be determined that the user wishes to touch the area.

In a preferred embodiment of the present invention, after the front camera (front camera) captures that the face image moves to a certain area beyond a certain threshold, the picture of the area and the corresponding touch point are gradually moved to the middle of the mobile phone. Easy for users to touch.

FIG. 3 is a structural block diagram of a mobile phone according to a preferred embodiment of the present invention. As shown in FIG. 3, the mobile phone includes a detecting module 32 and an executing module 34. The phone will be described below.

The detection module 32 performs face capture using the front camera to determine the edge area that the user wishes to touch.

When the currently captured face image is located in the middle area of the mobile phone, it can be considered that the user only needs to click the middle area of the mobile phone normally, and does not need to click on the edge area. That is, at this time, the plane of the mobile phone is basically facing the user's face, as shown in FIG.

When the currently captured face image moves to the edge area of the mobile phone and reaches a certain threshold, it is considered that the user wishes to click the edge area, that is, the user has slightly rotated the mobile phone according to the normal operation habit, and the area is slightly turned to himself to increase the thumb. The possibility of a sharp touch. The threshold value can be preset to a default value and can be adjusted in the setting. When the threshold value is reached, the rotation caused by the jitter of the mobile phone when the rotation has exceeded the middle area of the touch is eliminated, that is, the possibility of misjudgment is eliminated. Figures 5 through 12 are schematic representations of different edge regions of the handset.

When the currently captured face image moves to the edge area of the mobile phone after the threshold range is exceeded, the execution module performs a process of displaying the display screen and corresponding touch points.

The execution module 34 smoothly moves the display screen of the edge area that the user desires to touch and the corresponding touch point to the middle area of the mobile phone. The user simply clicks on the middle area to complete the operation.

The magnitude of this movement can be related to the extent to which the proactively captured face image exceeds a threshold. That is, the more the position of the face image exceeds the threshold, the greater the amplitude of the movement of the display screen and the corresponding touch point; the smaller the position of the face image exceeds the threshold, the smaller the amplitude of the movement of the display screen and the corresponding touch point. When the face image is restored to within the threshold range, the display also returns to the original no-movement state. The relationship between the display screen movement amplitude and the face image offset from the center area is as shown in FIG.

There are many ways to display the screen movement. The following are typical three types.

1) Linear translation. That is, the entire screen is translated in the opposite direction to the area that the user wishes to touch, and is discarded beyond the portion of the screen. As shown in Figure 14.

2) Linear compression. That is, the entire screen is compressed in the opposite direction to the area that the user wishes to touch. As shown in Figure 15.

3) Translation plus compression. That is, the picture of the area that the user wishes to touch is translated in the opposite direction, and the remaining areas are compressed. As shown in Figure 16.

The process of screen movement will be described in conjunction with the structural block diagram of the mobile phone shown in FIG.

17 is a flow chart of a screen display control method according to a preferred embodiment of the present invention. As shown in FIG. 17, the flow includes the following steps:

In step S1702, the front camera captures the face image position.

In step S1704, it is determined whether the captured face image position exceeds a preset threshold. If yes, step S1706 is performed; otherwise, step S1702 is performed.

Step S1706, processing the display screen and corresponding touch points.

The screen display control method of the preferred embodiment will be described below by a specific algorithm. The algorithm is used for calculating the moving range of the display screen and the positional relationship of the face image. The screen control display method is a method for determining and processing when the user intends to touch the upper left area of the screen (other areas are similar) under the algorithm.

As shown in FIG. 18, it is assumed that the center coordinates of the face image captured by the proactive image are (x, y), and the threshold values are x ∈ [X _left , X _right ], y ∈ [Y _down , Y _up ], and the algorithm is:

When x<X _left , the left edge of the screen is shifted to the right by X _left -x;

When x>X _right , the right edge of the screen shifts left xX _right ;

When y<Y _down , the lower edge of the screen moves up Y _down -y;

When y>Y _up , the upper edge of the screen moves down yY _up ;

If the resolution of the mobile phone is 1080×1920, set the coordinates of the pixel in the lower left corner of the mobile phone screen to be (0, 0), and the coordinates of the pixel in the upper right corner are (1080, 1920). Then set the threshold Xleft=360, Xright=720, Ydown=600, Yup=1200. As shown in Figure 18.

The judgment and processing steps when the user intends to touch the upper left area of the screen are as follows:

Step 1: The detection module uses the front camera for face capture. By default, the phone is facing the user's face. Corresponding to the face image center coordinates (x1, y1) in Fig. 18, 360 < x1 < 720, 600 < y1 < 1200. (x1, y1) is within the threshold range, and the display image does not need to be moved.

Step 2, the user gradually turns the upper left corner of the mobile phone to himself, and the proactively captured human face image gradually moves to the upper left of the mobile phone and first exceeds the threshold in the x direction. Corresponding to the center coordinate (x2, y2) of the face image in Fig. 18, x2 < 360, 600 < y2 < 1200. The x2 value is outside the threshold range and the display image needs to be shifted right.

Step 3: The execution module processes the display screen and the corresponding touch point to move to the right side of the mobile phone. The left edge of the picture moves 360-x2, and the left edge of the picture moves to the horizontal axis 360-x2 (following x2 real-time change); the vertical position of the picture is unchanged. That is, the coordinates of the pixel in the upper left corner of the screen are (360-x2, 1920).

Step 4: If the user still cannot touch the touch point after moving in step 3, continue to turn the upper left corner of the mobile phone to himself, and the proactively captured face image also continues to move to the upper left of the mobile phone and further exceeds the threshold in the y direction. Corresponding to the face image center coordinates (x3, y3) in Fig. 18, at this time x3 < 360, y3 > 1200. The X3 and y3 values all exceed the threshold range, and the displayed image needs to be shifted right and down.

Step 5: The execution module processes the display screen and the corresponding touch point to move to the lower right of the mobile phone. The left edge of the picture moves 360-x3, and the left edge of the picture moves to the horizontal axis 360-x3 (following x3 real-time change); the upper edge of the picture moves by y3-1200, and the upper edge of the picture moves to the vertical axis of the coordinate 3120. -y3 (following y3 real-time changes). That is, the coordinates of the pixel in the upper left corner of the screen are (360-x3, 3120-y3).

Step 6. After the user completes the touch, the screen of the mobile phone is gradually restored to the original state of the face of the user. Proactively capturing the face image also gradually moves to the center area until it returns to the threshold range, and the display gradually returns to the original There is no moving state at the beginning.

Since the front camera only needs to capture the position of the face, there is no quality requirement for the captured picture, that is, the configuration parameters such as the resolution of the proactive camera and the frame rate can be appropriately lowered, that is, the highest resolution and frame that can be supported by the camera are not required. The rate is set, so that the power consumption of the whole machine during the bright screen operation can be reduced.

In the preferred embodiment, the user's normal operation habits are used to implement automatic control, and the user can automatically implement full-screen touch of the large-screen mobile phone without completing any additional actions, and avoid false triggering by setting a threshold.

In the preferred embodiment, the face capture technology is used to detect the position change of the user's face relative to the plane of the mobile phone, thereby determining the screen area that the user intends to touch, and then adjusting the display screen and the corresponding touch point to facilitate the user's touch. On the big screen mobile phone. Since the front camera of the mobile phone is used for face capture to judge the user's intention, no hardware cost is added. Meanwhile, the technical solution of the preferred embodiment can cover all display interfaces, and both horizontal and vertical screen operations are applicable, and both left and right hand operations are applicable. Through the above-mentioned technology of the preferred embodiment of the present invention, the content of the edge area that the user wants to touch is automatically moved to the middle area of the mobile phone, and the user only needs to click the middle area to complete the operation, which greatly improves the convenience of manipulation.

Through the description of the above embodiments, those skilled in the art can clearly understand that the method according to the above embodiment can be implemented by means of software plus a necessary general hardware platform, and of course, by hardware, but in many cases, the former is A better implementation. Based on such understanding, the technical solution of the present invention, which is essential or contributes to the prior art, may be embodied in the form of a software product stored in a storage medium (such as ROM/RAM, disk, The optical disc includes a number of instructions for causing a terminal device (which may be a cell phone, a computer, a server, or a network device, etc.) to perform the methods described in various embodiments of the present invention.
