The embodiments of the present disclosure will be described in detail below with reference to the drawings.

It should be noted that the terms “first”, “second”, “third” and the like in the present disclosure are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

FIG. 1 exemplarily illustrates a system architecture applicable to an embodiment of the present disclosure.

As shown in FIG. 1, the system architecture 100 includes a smart TV 101 and a remote control 102. The remote controller 102 may send a control instruction to the smart television 101 in a wireless manner.

The smart TV 101 is equipped with an operating system that allows users to install and uninstall various applications by themselves. The remote controller 102 of the smart television is a wireless transmitting device, and a user can realize human-computer interaction with the smart television 101 by operating the remote controller 102. In a possible application scenario, the remote controller 102 encodes the user's key information through digital encoding technology, and emits light waves through infrared diodes. The light waves are converted into electrical signals by the infrared receiver of the smart TV 101. The signal is then decoded by the processor to demodulate the corresponding instruction and execute the instruction, so as to achieve the purpose of controlling the smart TV 101 to complete the required operation.

Optionally, the system architecture 100 may further include a set-top box (not shown in the figure) connected to the smart television. The set-top box is also called a digital video conversion box. It is used to convert compressed digital signals into TV content and display it on a smart TV. The set-top box can be built in or connected to the smart TV. The control instruction sent by the remote control is received and decoded by the set-top box, and the set-top box sends the decoded control instruction to the smart TV.

The remote controller may also include other mobile user equipment. The mobile user equipment can establish a wireless communication connection with the smart TV, and send control instructions to the smart TV through the wireless communication connection. The mobile user equipment may be a smart phone, a tablet computer, a Personal Digital Assistant (PDA), a smart wearable device, or the like.

The operating system mounted on the smart TV 101 may be an Android system, a Windows system, or a device provider's self-built system. The disclosure does not specifically limit the type of the operating system mounted on the smart television 101.

Based on the above-mentioned system architecture 100, in the embodiment of the present disclosure, the user can perform human-computer interaction with the smart TV 101 through the remote controller 102, and perform zoom operations on the focus frame in the interface of the smart TV 101.

The zoom operation of the focus frame of the smart TV 101 interface provided by the present disclosure may be implemented by a software module within an application framework in the smart TV operating system.

As shown in FIG. 2, it is a flowchart of a method for zooming a user interface focus frame of a smart television according to an embodiment of the present disclosure. This process can be implemented by a smart TV, or by a user interface focus frame zooming device in a smart TV.

As shown, the method includes:

S201: Display a user interface. A first focus frame is displayed in the user interface.

For convenience of description, the focus frame in the user interface is referred to as a first focus frame.

The first focus frame may be selected by a user. For example, the user may select a region on the user interface through a remote control to form the first focus frame. The first focus frame may also be automatically selected by an application program to which the user interface belongs.

For example, taking a smart TV image processing application as an example, a user enters an image processing application installed in a smart TV by operating a button on a remote control, selects a photo to be image processed, and displays the picture in a user interface. The application can determine the area where the person's head is located in the picture through image recognition, and set a focus frame based on the area (ie, set the area as the focus frame area). The user can also select an area in the photo by operating the remote control, and set a focus frame according to the area, in order to perform image recognition on the area in the focus frame, as shown in Figure 3, which is the user interface in the image processing application of the smart TV. The first focus frame displayed.

It should be noted that the shape of the first focus frame in the present disclosure may be a square, a circle, a rectangle, or an irregular shape, etc., which is not limited in the present disclosure.

S202: In response to a remote control key command acting on the first focus frame, delete the first focus frame and display the second focus frame.

Optionally, when the second focus frame is larger than the first focus frame, the area range of the first focus frame is within the area range of the second focus frame. That is, when the focus frame is enlarged, the area of the enlarged second focus frame covers the area of the first focus frame before enlargement. When zooming in on the focus frame, in some embodiments, the center point of the first focus frame can be used as a reference point to zoom in, so that the center point of the second focus frame and the center point of the first focus frame coincide; in other embodiments, Taking the rectangular focus frame as an example, the lower left corner vertex of the first focus frame can also be used as a reference point for zooming, so that the lower left corner vertex of the second focus frame coincides with the lower left corner vertex of the first focus frame.

Optionally, when the second focus frame is smaller than the first focus frame, the area range of the second focus frame is within the area range of the first focus frame. That is, when the focus frame is reduced, the area of the reduced second focus frame is located in the area of the first focus frame before reduction. When reducing the focus frame, in some embodiments, the center point of the first focus frame can be used as a reference point to reduce the center point of the second focus frame and the first focus frame. In other embodiments, Taking the rectangular focus frame as an example, the apex of the lower left corner of the first focus frame can also be used as a reference point for reduction. In this way, the vertex of the lower left corner of the second focus frame coincides with the vertex of the first focus frame.

FIG. 4 a exemplarily illustrates a focus frame magnification using a rectangular focus frame as a reference point when a rectangular focus frame is taken as an example, wherein the center point of the second focus frame 402 and the center point of the first focus frame 401 are enlarged. coincide. FIG. 4b exemplarily illustrates a focus frame magnification using the lower left vertex of the focus frame as a reference point when the rectangular focus frame is taken as an example. The lower left vertex of the second focus frame 404 and the lower left vertex of the first focus frame 403 are illustrated. coincide.

It should be noted that, in FIG. 4a and FIG. 4b, the first focus frame is displayed as a dashed frame in order to compare the size and position of the focus frame before and after the enlargement. In specific implementation, before displaying the second focus frame, the first The focus frame will be deleted.

It should be noted that, the embodiment of the present disclosure does not limit the manner in which the focus frame is enlarged or reduced (such as the reference point on which the enlargement or reduction is based).

Optionally, the magnification may be set in advance, so that the size of the first focus frame is multiplied by the magnification to obtain the size of the second focus frame. For example, taking a square focus frame as an example, if the magnification is 1.5, the side length of the second focus frame is equal to the product of the side length of the first focus frame and the magnification (1.5). Specifically, if the If the side length is 1, the side length of the second focus frame is 1.5l.

Optionally, a reduction factor may be set in advance, so that the size of the first focus frame is divided by the reduction factor to obtain the size of the second focus frame. For example, taking a square focus frame as an example, if the reduction factor is 1.2, the side length of the second focus frame is equal to the side length of the first focus frame divided by the reduction factor (1.2).

Optionally, the shape of the second focus frame is the same as or matches the shape of the first focus frame. Fig. 5a exemplarily shows an example in which the shape of the second focus frame is the same as that of the first focus frame. As shown in the figure, the first focus frame 501 is rectangular, and the magnification method is to use the center point as a reference point to enlarge. The enlarged second focus frame 502 is also rectangular. Fig. 5b exemplarily shows an example in which the shapes of the second focus frame and the first focus frame match. As shown in the figure, the first focus frame 503 is circular, and the magnification method is to use the center point as the base station point to enlarge. Since the first focus frame 503 is located at the boundary of the user interface, after the focus frame is enlarged, the shape of the second focus frame 504 is no longer circular, but its shape matches the shape of the first focus frame 503.

It should be noted that, in FIG. 5a and FIG. 5b, the first focus frame is displayed as a dashed frame in order to compare the positions of the focus frames before and after the enlargement. In specific implementation, before displaying the second focus frame, the first focus frame Will be deleted.

In the above embodiment, the currently displayed user interface includes a first focus frame, and upon receiving a remote control key command acting on the first focus frame, in response, deleting the first focus frame and displaying a second focus frame The area range of the second focus frame is within the range of the first focus on or the area range of the first focus frame is within the area of the second focus frame. The focus frame can be zoomed by the remote control. And flexible zoom operation of the focus frame of the user interface, thereby improving the user experience.

Based on the above process of the present disclosure, the focus frame zoom operation can be implemented by one or more of a volume up key, a volume down key, a confirmation key, or other keys on the remote control.

The focus frame zooming method provided by the present disclosure is described below by taking the volume up key, volume down key, and confirmation key on the remote controller as examples.

Referring to FIG. 6, a flowchart of a method for enlarging a focus frame of a user interface by using a volume increase button on a remote controller according to the present disclosure.

The method includes:

S601: Receive a volume increase key command that acts on the first focus frame and is generated by the volume increase key on the remote control.

S602: Delete the first focus frame and display the second focus frame according to the volume increase key instruction. The size of the second focus frame is larger than the size of the first focus frame.

Based on the above process, the magnification can be set in advance, the magnification is equal to the first set magnification, and the value is greater than 1. In S602, the size of the second focus frame may be determined according to the set magnification, so that the magnification of the size of the second focus frame compared with the size of the first focus frame is equal to the first set multiple.

Taking the first focus frame shown in FIG. 3 as an example, the side length of the first focus frame is l, the magnification is 1.5 times, and the magnification method is to use the center as a base point to enlarge. The user clicks the volume increase button on the remote control, and in response to the volume increase command corresponding to the volume increase button, deletes the first focus frame of the display interface, multiplies by 1.5 on the basis of the length of the side of the first focus frame, and zooms in again. The second focus frame shown in FIG. 7 is drawn (only the focus frames before and after the enlargement are shown in FIG. 7), and the side length is 1.5 l. In this way, if the user clicks the volume up button on the remote control again, the interface displays a square focus frame with a side length of 2.25l. It should be noted that FIG. 7 shows the first focus frame in a dashed frame manner to compare the positions of the focus frames before and after the enlargement. In specific implementation, the first focus frame will be deleted before the second focus frame is displayed.

In a possible implementation manner, the magnification of the focus frame may be additionally set, and the magnification is equal to the third setting magnification, which is used when the user presses the volume increase button for magnification of the focus frame, the third setting The magnification is different from the above-mentioned first set multiple. For example, it can be smaller than the first set multiple. From the user's intuitive experience, you can slowly zoom in on the size of the focus frame by pressing and holding the volume up button on the remote control. , Can increase the flexibility of focus frame size control, and enhance the user experience. Specifically, if the user presses and holds the volume up button on the remote controller, the focus frame is drawn according to the focus frame magnification set separately. Further, the currently drawn focus frame may be displayed only when the user raises the volume up button. Since the volume increase key is pressed for a long time, the volume increase key command is sent to the smart TV at a certain interval. The smart TV responds based on each volume increase key command received. Therefore, when using the above method, long press the volume increase key The longer the time, the larger the size of the focus frame displayed. The user can control the length of time by pressing and holding the volume up button to get the focus frame with the corresponding magnification effect.

Optionally, when the size of the focus frame is equal to the size of the maximum focus frame or the edge of the focus frame coincides with the maximum boundary of the focus frame, when the user operates the volume up button on the remote control, the user interface retains the focus frame and a prompt message appears, Prompt that the size of the focus frame has reached the maximum value, and can no longer be enlarged.

It should be noted that the size of the maximum size focus frame in the above embodiment is determined by the position and shape of the focus frame and the size of the user interface, which is not limited in this disclosure.

In the following, a square focus frame is taken as an example, and the user interface shown in FIG. 3 and the system architecture shown in FIG. 8 are taken as examples to describe the process shown in FIG. 8 in detail.

FIG. 8 exemplarily shows a system architecture of a smart TV based on the Android system. The system architecture shown in FIG. 8 includes a system kernel 801, an application framework layer 802, and an application layer 803. Among them, the system kernel 801 includes modules such as an input device driver (Input Device Driver). The application framework layer 802 includes system services such as an input management service, a monitoring control service, and a window management service. The application layer 803 includes a plurality of applications such as an image processing application.

Taking an image processing application as an example, when the application is installed, it will register the key values it wants to monitor with the monitoring control service in the application framework layer 802. The database of the monitoring control service stores the key values registered by the application and related Monitoring information. In this example, the key value registered by the image processing application includes the key value of the volume key. The registered monitoring information is shown in Table 1.

Table 1: Monitoring information corresponding to the volume increase key registered by the image processing application

Application name	Key-value	Action	Whether to distribute
Image processing application	Key_vol_inc	response	False

Among them, the remote control buttons registered by the image processing application include a volume increase button, and the key value is represented as Key_vol_inc. Action means that if an event corresponding to the key value is received, a response is required. False means that if the event corresponding to the key value is received, it will not continue to be distributed downwards, that is, the application only executes the response corresponding to the key value and does not execute the default response of the key value. For example, after the image processing application receives the event of the key value, it only performs the zoom-in operation of the focus frame and does not perform the default volume increase operation.

The wireless signal (volume increase key command) generated after the user operates the volume up button on the remote control is read by the input device driver in the smart TV system architecture. The input device driver processes the signal and gains The volume event (including the key value Key_vol_inc) is sent to the monitoring control service in the application framework layer 802; the monitoring control service determines the current application (image processing application) based on the monitoring information registered by the application (as shown in Table 1). (Program) Whether the key value is registered and registered in response to the key value; if so, the volume increase event is sent to the image processing application in the application layer 803; the image processing application executes corresponding processing according to the received volume increase event In this example, the focus frame is zoomed in. Relevant system services in the application framework layer need to be called when the focus frame zoom-in operation is performed. After the focus frame zoom-in operation is completed, the monitoring control service in the application framework layer determines that it will no longer distribute according to the key values registered in the application and related information. For the volume increase event, the zoom focus frame processing operation is completed.

The above mainly introduces the solutions provided by the embodiments of the present disclosure from the perspective of human-computer interaction. It can be understood that, in order to implement the foregoing functions, the terminal includes a hardware structure and / or a software module corresponding to each function. With reference to the units (devices, devices) and algorithm steps of the various examples described in the embodiments disclosed in this disclosure, the embodiments of this disclosure can be implemented in the form of hardware or a combination of hardware and computer software. Whether a certain function is performed by hardware or computer software-driven hardware depends on the specific application of the technical solution and design constraints. Those skilled in the art may use different methods to implement the described functions for each specific application, but such implementation should not be considered to be beyond the scope of the technical solutions of the embodiments of the present disclosure.

Referring to FIG. 9, a flowchart of a method for reducing a focus frame of a user interface by using a volume reduction button on a remote controller according to the present disclosure.

The method includes:

S901: Receive a volume reduction key command acting on the first focus frame generated by the volume reduction key on the remote control.

S902: Delete the first focus frame and display the second focus frame according to the volume reduction key instruction. The size of the second focus frame is smaller than the size of the first focus frame.

Based on the above process, a reduction ratio can be set in advance, the reduction ratio is equal to the second set multiple, and the value is greater than 1. In S902, the size of the second focus frame may be determined according to the set reduction ratio, so that the reduction ratio of the size of the second focus frame compared with the size of the first focus frame is equal to the second set multiple.

Taking the first focus frame in FIG. 3 as an example, the side length of the first focus frame is 1 and the reduction factor is 2 times. The magnification method is to use the center as a base point to enlarge. The user clicks the volume reduction button on the remote control, and in response to the volume reduction command corresponding to the volume reduction button, deletes the first focus frame of the display interface, and divides by 2 based on the length of the side of the first focus frame to reduce it. The second focus frame shown in FIG. 10 is redrawn (only the focus frames before and after the reduction are shown in FIG. 10), and the side length is 0.5l. In this way, if the user clicks the volume down button on the remote control again, the interface displays a square focus frame with a side length of 0.25l. It should be noted that FIG. 10 displays the first focus frame in a dashed frame manner in order to compare the positions of the focus frames before and after the reduction. In specific implementation, the first focus frame will be deleted before the second focus frame is displayed.

In a possible implementation manner, the focus frame reduction ratio may be additionally set, and the reduction ratio is equal to the fourth setting multiple, which is used when the user reduces the focus frame when the user presses the volume reduction button for a long time, the fourth setting The multiple is different from the second set multiple, for example, it can be smaller than the second set multiple. From the user's intuitive experience, you can slowly reduce the size of the focus frame by pressing and holding the volume down button on the remote control. , Can increase the flexibility of focus frame size control, and enhance the user experience. Specifically, if the user long presses the volume reduction button on the remote controller, the focus frame is drawn according to the focus frame reduction factor that is additionally set. Further, the currently drawn focus frame may be displayed only when the user raises the volume reduction button. Because the volume increase key is pressed for a long time, it will send volume increase key instructions to the smart TV at a certain interval. The smart TV responds based on each key volume key instruction received. Therefore, when using the above method, long press the volume decrease key The longer the time, the smaller the size of the focus frame displayed. The user can control the length of time by pressing and holding the volume reduction button to obtain a focus frame with a corresponding reduction effect.

Optionally, when the size of the focus frame is equal to the size of the smallest focus frame, when the user operates the volume reduction button on the remote control, the user interface retains the focus frame and a prompt message appears, indicating that the size of the focus frame has reached the minimum value , You cannot zoom out anymore.

It should be noted that the minimum size focus frame size in the above embodiments is determined by the position and shape of the focus frame and the size of the user interface, which is not limited in this disclosure.

In the following, a square focus frame is taken as an example, and the user interface shown in FIG. 3 and the system architecture shown in FIG. 8 are taken as examples to describe the process shown in FIG. 9 in detail.

Taking an image processing application as an example, when the application is installed, it will register the key values it wants to monitor with the monitoring control service in the application framework layer 802. The database of the monitoring control service stores the key values registered by the application and related Monitoring information. In this example, the key value registered by the image processing application includes the key value of the volume reduction key. The registered monitoring information is shown in Table 2.

Table 2: Monitoring information corresponding to the volume reduction key registered by the image processing application

Application name	Key-value	Action	Whether to distribute
Image processing application	Key_vol_dec	response	False

Among them, the remote control buttons registered by the image processing application include a volume reduction button, and the key value is represented as Key_vol_dec. Action means that if an event corresponding to the key value is received, a response is required. False means that if the event corresponding to the key value is received, it will not continue to be distributed downwards, that is, the application only executes the response corresponding to the key value and does not execute the default response of the key value. For example, after receiving an event of the key value, the image processing application only performs the zoom-out operation of the focus frame without performing the default volume reduction operation.

The wireless signal (volume reduction key instruction) generated after the user operates the volume down button on the remote control is read by the input device driver (Input Device Driver) in the smart TV system architecture, and the input device driver processes the signal to reduce the The volume event (including the key value Key_vol_dec) is sent to the monitoring control service in the application framework layer 802; the monitoring control service determines the current application (image processing application) based on the monitoring information registered by the application (as shown in Table 2). (Program) Whether the key value is registered and registered in response to the key value; if so, the volume reduction event is sent to the image processing application in the application layer 803; the image processing application executes corresponding processing according to the received volume reduction event In this example, the focus frame is zoomed out. Relevant system services in the application framework layer need to be called when the focus frame reduction operation is performed. After the focus frame reduction operation is performed, the monitoring control service in the application framework layer determines that it will no longer be distributed based on the key values registered by the application and related information. At this volume reduction event, the processing of reducing the focus frame is completed.

Referring to FIG. 11, a flowchart of a method for enlarging or reducing a focus frame of a user interface by using a confirmation button on a remote controller according to the present disclosure.

The method includes:

S1101: Receive a confirmation key command acting on the first focus frame generated by the confirmation key on the remote control.

S1102: Obtain zoom instruction information according to the received confirmation key instruction, and determine whether the zoom instruction information is used to indicate a focus frame zoom-in operation or a focus frame zoom-out operation. If the zoomed instruction information is a focus frame zoom-in operation, execute S1103, otherwise, execute S1104.

S1103: According to the zoom instruction information, the first focus frame is deleted and the second focus frame is displayed. The size of the second focus frame is larger than the size of the first focus frame.

In S1103, the size of the second focus frame may be determined according to the first set multiple, so that the magnification of the size of the second focus frame compared to the size of the first focus frame is equal to the first set multiple.

In a possible implementation manner, the user can press and hold the confirmation button to enlarge the focus frame according to the third set multiple to display the focus frame currently drawn when the user raises the confirmation button, so that the size of the drawn focus frame is larger than that of the first focus frame. The size of a focus frame.

Optionally, if a part of the edge of the first focus frame coincides with a part of the largest border of the focus frame, and the zoom instruction information indicates that the focus frame is zoomed in, the corresponding edge of the second focus frame displayed in response to the volume increase key instruction It still coincides with a part of the boundary of the largest boundary of the focus frame.

S1104: According to the zoom instruction information, the first focus frame is deleted and the second focus frame is displayed. The size of the second focus frame is smaller than the size of the first focus frame.

In S1104, the size of the second focus frame may be determined according to the second set multiple, so that the reduction ratio of the size of the second focus frame compared to the size of the first focus frame is equal to the second set multiple.

In a possible implementation manner, the user can press and hold the confirmation button to reduce the focus frame according to the fourth set multiple, and display the focus frame currently drawn when the user raises the confirmation button, so that the size of the drawn focus frame is smaller than the first. The size of a focus frame.

The zoom instruction information in the above embodiments can be set by the system. For example, setting the initial value of the zoom instruction information to 0 indicates that the default zoom operation is to zoom in the focus frame, and setting the initial value of the zoom instruction information to 1 indicates that the default zoom operation is Reduce the focus frame.

In some embodiments, the initial value of the zoom instruction information is set by the system. During the running process, the value of the zoom instruction information can be changed according to the zoom frame's enlargement and reduction, so as to realize continuous change of the focus frame size.

For example, if the current zoom instruction information is used to indicate the zoom frame operation of the focus frame, after the smart TV receives the confirmation key instruction, since the current zoom instruction information is used to indicate the zoom frame operation of the focus frame, the zoom frame operation of the focus frame is performed. And determine whether the size of the enlarged second focus frame is equal to the size of the largest focus frame or the edge of the second focus frame coincides with the largest boundary of the focus frame. If it is, it indicates that the current focus frame has been enlarged to the maximum extent, then set the zoom The instruction information is used to instruct a focus frame zoom-out operation. In this way, after receiving the confirmation key instruction acting on the focus frame again, the focus frame can be reduced.

For another example, if the current zoom instruction information is used to indicate the zoom-out operation of the focus frame, after the smart TV receives the confirmation key instruction, because the current zoom instruction information is used to indicate the zoom-out operation of the focus frame, the focus frame is reduced. Operation, and determine whether the size of the reduced second focus frame is equal to the size of the smallest focus frame. If yes, it indicates that the current focus frame has been reduced to a minimum degree, and the zoom instruction information is set to instruct the focus frame to zoom in. In this way, after receiving the confirmation key instruction acting on the focus frame again, a zoom-in operation of the focus frame can be performed.

In some embodiments, the value of the zoom indication information remains unchanged.

Taking the initial value of the zoom instruction information to instruct the focus frame to zoom in as an example, after receiving the confirmation key instruction acting on the first focus frame, it can be determined whether the size of the first focus frame is equal to the size of the largest focus frame or the Whether the edge of the first focus frame coincides with the largest boundary of the focus frame. If the answer is yes, it indicates that the focus frame can no longer be enlarged. Therefore, delete the first focus frame and use the minimum focus frame size or the default focus frame size or the initial focus frame. The size of the second focus frame. The size of the initial focus frame is the size when the focus frame is initially generated.

Taking the initial value of the zoom instruction information to instruct the focus frame to reduce the operation as an example, after receiving the confirmation key instruction acting on the first focus frame, it can be determined whether the size of the first focus frame is equal to the size of the minimum focus frame or Whether the edge of the focus frame coincides with the minimum boundary of the focus frame. If the answer is yes, it indicates that the focus frame can no longer be reduced. Therefore, the first focus frame is deleted and the maximum focus frame size or the default focus frame size or the initial focus frame Size, the second focus frame is displayed.

In the following, a square focus frame is taken as an example, and the user interface shown in FIG. 3 and the system architecture shown in FIG. 8 are taken as examples to describe the process shown in FIG. 11 in detail.

Taking an image processing application as an example, when the application is installed, it will register the key values it wants to monitor with the monitoring control service in the application framework layer 802. The database of the monitoring control service stores the key values registered by the application and related Monitoring information. In this example, the key value registered by the image processing application includes the key value of the confirmation key. The registered monitoring information is shown in Table 3.

Table 3: Monitoring information corresponding to the confirmation key registered by the image processing application

Application name	Key-value	Action	Whether to distribute
Image processing application	Key_vol_ok	response	True

The remote control buttons registered by the image processing application include a confirmation button, and the key value is represented as Key_vol_ok. Action means that if an event corresponding to the key value is received, a response is required. True means that after receiving the event corresponding to the key value, it continues to distribute downwards, that is, the application not only executes the response corresponding to the key value but also executes the default response of the key value. For example, after receiving an event of the key value, the image processing application performs a default confirmation operation after performing a zoom-in or zoom-out operation of the focus frame.

The wireless signal (confirmation key command) generated after the user operates the confirmation button on the remote control is read by the input device driver (Input Device Driver) in the smart TV system architecture, and the input device driver processes the signal to obtain a confirmation event ( This event includes the key value (Key_vol_ok) and sends it to the listening control service in the application framework layer 802; the listening control service determines whether the current application (image processing application) is based on the monitoring information registered by the application (as shown in Table 3). The key value is registered and registered in response to the key value. If yes, the confirmation event is sent to the image processing application in the application layer 803; the image processing application determines whether the event is a zoom-in operation or a zoom-out operation according to the received confirmation event. And execute the corresponding processing. In this example, it is determined that the event is a zoom-in operation. Relevant system services in the application framework layer need to be called when the focus frame zoom-in operation is performed. After the focus frame zoom-in operation is completed, the monitoring control service in the application framework layer distributes the confirmation event according to the key value and related information registered by the application. , At this point, confirm that the zoom-in operation of the focus frame corresponding to the button is completed.
