Detailed Description

The embodiments of the present disclosure are described in detail below with reference to the accompanying drawings.

It is noted that the terms "first," "second," "third," and the like in this disclosure are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order.

Fig. 1 illustrates a system architecture suitable for use with embodiments of the present disclosure.

As shown in fig. 1, the system architecture 100 includes an intelligent tv 101 and a remote controller 102. The remote controller 102 may send a control instruction to the smart tv 101 in a wireless manner.

The smart television 101 is provided with an operating system, which allows a user to install and uninstall various application programs. The smart tv remote controller 102 is a wireless transmitter, and a user can interact with the smart tv 101 by operating the remote controller 102. In a possible application scenario, the remote controller 102 encodes the key information of the user by using a digital encoding technology, emits a light wave through an infrared diode, converts the received infrared signal into an electrical signal by the infrared receiver of the smart tv 101 through the light wave, decodes the electrical signal by using the processor, demodulates a corresponding instruction, and executes the instruction, so as to achieve the purpose of controlling the smart tv 101 to complete the required operation.

Optionally, a set-top box (not shown) connected to the smart tv may also be included in the system architecture 100. The set-top box is also called a digital video conversion box and is used for converting the compressed digital signals into television contents and displaying the television contents on the intelligent television. The set-top box can be arranged in the intelligent television and can also be externally connected with the intelligent television. The control instruction sent by the remote controller is received and decoded by the set-top box, and the set-top box sends the decoded control instruction to the intelligent television.

The remote control may also comprise other mobile user equipment. The mobile user equipment can establish wireless communication connection with the intelligent television and send a control instruction to the intelligent television through the wireless communication connection. The mobile user equipment may be a smartphone, a tablet computer, a Personal Digital Assistant (PDA), an intelligent wearable device, or the like.

The operating system installed on the smart television 101 may be an Android (Android) system, a Windows (Windows) system, or a device provider self-built system. The present disclosure is not particularly limited as to the type of operating system mounted on the smart tv 101.

Based on the system architecture 100, in the embodiment of the present disclosure, a user may perform a human-computer interaction with the smart tv 101 through the remote controller 102 to perform a zoom operation on a focus frame in an interface of the smart tv 101.

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

As shown in fig. 2, a flowchart of a method for zooming a user interface focus frame for a smart tv set is provided for an embodiment of the present disclosure. The process can be realized by the intelligent television, or by a user interface focus frame zooming device in the intelligent television.

As shown, the method includes:

s201: and displaying a user interface, wherein a first focus frame is displayed in the user interface.

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

The first focus frame may be user-selectable, for example, a user may select an area on the user interface via a remote control to form the first focus frame. The first focus frame may also be automatically selected by an application to which the user interface belongs.

For example, taking an image processing application of a smart television as an example, a user enters the image processing application installed in the smart television by operating a key of a remote controller, selects a photo to be subjected to image processing and displays the photo in a user interface, and the application can determine an area where a portrait of a person is located through image recognition and set a focus frame based on the area (i.e., the area is set as a focus frame area). The user can also select an area in the photo by operating the remote controller, and set a focus frame so as to perform image recognition on the area in the focus frame, as shown in fig. 3, which is the first focus frame displayed in the user interface of the image processing application of the smart television.

In the present disclosure, the shape of the first focus frame may be a square, a circle, a rectangle, an irregular shape, or the like, which is not limited in the present disclosure.

S202: and deleting the first focus frame and displaying the second focus frame in response to a remote controller key instruction acting on the first 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 second focus frame after enlargement covers the area of the first focus frame before enlargement. When the focus frame is enlarged, in some embodiments, the center point of the first focus frame may be used as a reference point for enlargement, so that the center points of the second focus frame and the first focus frame coincide; in other embodiments, taking a rectangular focus frame as an example, the left corner vertex of the first focus frame may also be used as a reference point for zooming in, so that the left corner vertex of the second focus frame coincides with the 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 second focus frame after the reduction is located within the area of the first focus frame before the reduction. When the focus frame is reduced, in some embodiments, the focus frame may be reduced by using the center point of the first focus frame as a reference point, so that the center points of the second focus frame and the first focus frame coincide; in other embodiments, taking a rectangular focus frame as an example, the left corner vertex of the first focus frame may also be used as a reference point for performing the reduction, so that the left corner vertex of the second focus frame coincides with the left corner vertex of the first focus frame. Fig. 4a exemplarily shows a schematic diagram of performing focus frame enlargement with a focus frame center point as a reference point when taking a rectangular focus frame as an example, wherein a center point of the second focus frame 402 coincides with a center point of the first focus frame 401. Fig. 4b exemplarily shows a schematic diagram of performing focus frame enlargement by using the lower left vertex of the focus frame as a reference point when taking a rectangular focus frame as an example, wherein the lower left vertex of the second focus frame 404 coincides with the lower left vertex of the first focus frame 403. In fig. 4a and 4b, the first focus frame is shown in a dashed-line frame manner, so as to compare the positions of the focus frames before and after enlargement, and in particular, the first focus frame is deleted before the second focus frame is displayed.

It should be noted that, the embodiment of the present disclosure does not limit the manner of zooming in or out the focus frame (for example, a reference point on which zooming in or zooming out is based).

Alternatively, 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 side length of the first focus frame is l, the side length of the second focus frame is 1.5l.

Alternatively, a reduction factor may be preset, 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 that the second focus frame has the same shape as the first focus frame, and as shown, the first focus frame 501 has a rectangular shape and is enlarged in a manner of enlarging with the center point as a reference point. The enlarged second focus frame 502 is also rectangular. Fig. 5b exemplarily shows an example of matching the shape of the second focus frame with the shape of the first focus frame, and as shown, the first focus frame 503 is circular and enlarged by taking the center point as the base station point. Since the first focus frame 503 is located at the boundary of the user interface, the shape of the second focus frame 504 is no longer circular after the focus frame is enlarged, but its shape matches the shape of the first focus frame 503. In fig. 5a and 5b, the first focus frame is shown in a dashed-line frame manner, so as to compare the positions of the focus frames before and after enlargement, and in particular, the first focus frame is deleted before the second focus frame is displayed.

In the above embodiment, the currently displayed user interface includes the first focus frame, and after receiving a remote controller key instruction acting on the first focus frame, in response, the first focus frame is deleted, and the second focus frame is displayed, where an area range of the second focus frame is within an area range of the first focus, or an area range of the first focus frame is within an area range of the second focus frame, so that zooming processing on the focus frame and flexibility of zooming operation on the user interface focus frame through the remote controller can be implemented, and user experience is improved.

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

The focus frame zooming method provided by the present disclosure is described below by taking an increase volume key, a decrease volume key, and a confirm key on a remote controller as examples, respectively.

Referring to fig. 6, a flowchart of a method for implementing zoom-in of a focus frame of a user interface by an increase volume button on a remote controller is provided for the present disclosure.

The method comprises the following steps:

s601: and receiving a volume increasing key instruction which is generated by a volume increasing key on the remote controller and acts on the first focus frame.

S602: and deleting the first focus frame according to the increase amount key instruction, and displaying a second focus frame, wherein the size of the second focus frame is larger than that of the first focus frame.

Based on the above process, the amplification factor can be preset, and the amplification factor is equal to the first setting factor and is greater than 1. In S602, the size of the second focus frame may be determined according to the set magnification such 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 magnification.

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 is based on the center. The user clicks the volume increasing key on the remote controller, responds to the volume increasing instruction corresponding to the volume increasing key, deletes the first focus frame of the display interface, multiplies 1.5 by the side length l of the first focus frame for amplification, and redraws to obtain a second focus frame as shown in fig. 7, wherein the side length is 1.5l. In this manner, if the user clicks the volume up button on the remote control again, the interface displays a square focus box with a side length of 2.25 l. It should be noted that fig. 7 shows the first focus frame in a dashed line frame manner, so as to compare the positions of the focus frames before and after enlargement, and in particular, the first focus frame is deleted before the second focus frame is displayed.

In a possible implementation manner, the magnification factor of the focus frame may be additionally set, where the magnification factor is equal to a third setting factor, and is used when the user presses the volume increasing button for a long time to enlarge the focus frame, and the third setting factor is different from the first setting factor in size, for example, may be smaller than the first setting factor, so that from the intuitive experience of the user, the size of the focus frame may be slowly enlarged by pressing the volume increasing button on the remote controller for a long time, and the flexibility of controlling the size of the focus frame may be improved, and the user experience may be improved. Specifically, if the user presses the volume up key on the remote controller for a long time, the focus frame is drawn at the focus frame magnification that is additionally set. Further, the currently drawn focus frame may be displayed only when the user lifts the increase volume key. Because the volume increasing key is pressed for a long time, the volume increasing key instruction is sent to the smart television at a certain time interval, and the smart television responds based on each received volume increasing key instruction, when the method is adopted, the longer the time for pressing the volume increasing key is, the larger the size of the displayed focus frame is, and the user can obtain the focus frame with the corresponding amplification effect by controlling the time length for pressing the volume increasing key for a long time.

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, and a user operates a volume increasing button on the remote controller, the user interface keeps the focus frame, and prompt information appears to prompt that the size of the focus frame reaches the maximum value and cannot be amplified any more.

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

The following describes the flow shown in fig. 8 in detail by taking a square focus frame as an example and combining the user interface shown in fig. 3 and the system architecture shown in fig. 8 as an example.

Fig. 8 exemplarily shows a system architecture of an intelligent television based on an Android system, and the system architecture shown in fig. 8 includes a system kernel 801, an application framework layer 802, and an application layer 803. The system kernel 801 includes modules such as an Input Device Driver (i.e., driver). The application framework layer 802 includes system services such as input management service, listening control service, window management service, and the like. 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 registers a key value that it wants to monitor with a monitoring control service in the application framework layer 802, and stores the key value registered by the application and related monitoring information in a database of the monitoring control service.

Table 1: monitoring information corresponding to volume-up key registered by image processing application program

Application name	Key value	Action	Whether or not to distribute
				Image processing application program	Key_vol_inc	Response to	False

The remote controller keys registered by the image processing application program comprise volume increasing keys, and Key values of the volume increasing keys are represented as Key _ vol _ inc. The Action indicates that a response needs to be performed if an event corresponding to the key value is received. False indicates that downward distribution is not continued if an event corresponding to the key value is received, that is, the application only executes a response corresponding to the key value and does not execute a default response of the key value. For example, the image processing application program receives the key value event and only performs the zoom-in operation of the focus frame without performing the default volume-up operation.

A wireless signal (volume increasing Key instruction) generated after a user operates a volume increasing Key on a remote controller is read by an Input Device Driver in an intelligent television system architecture, and the signal is processed by the Input Device Driver to obtain a volume increasing event (the event comprises a Key value Key _ vol _ inc) and sent to a monitoring control service in an application framework layer 802; the interception control service determines whether the current application (image processing application) registers the key value and registers as responding to the key value according to the interception information (shown in table 1) registered by the application, and if so, sends the volume increase event to the image processing application in the application layer 803; the image processing application executes corresponding processing, in this example, an enlargement operation of the focus frame, in accordance with the received sound volume increasing event. And when the focus frame amplification operation is completed, the monitoring control service of the application framework layer determines that the voice volume increasing event is not distributed any more according to the key value registered by the application program and the related information, so that the focus frame amplification processing operation is completed.

The above description mainly introduces the scheme provided by the embodiments of the present disclosure from the perspective of human-computer interaction. It is understood that the terminal includes corresponding hardware structures and/or software modules for performing the respective functions in order to implement the above-described functions. The units (devices, means) and algorithm steps of each example described in connection with the embodiments disclosed in the disclosure may be implemented in hardware or a combination of hardware and computer software. Whether a function is performed as hardware or computer software drives hardware depends upon the particular application and design constraints imposed on the solution. Skilled artisans may implement the described functionality in varying ways for each particular application, but such implementation decisions should not be interpreted as causing a departure from the scope of the present disclosure.

Referring to fig. 9, a flowchart of a method for reducing a focus frame of a user interface by a volume-down button on a remote controller is provided.

The method comprises the following steps:

s901: and receiving a volume reduction key instruction which is generated by a volume reduction key on the remote controller and acts on the first focus frame.

S902: and deleting the first focus frame according to the volume reduction key instruction, and displaying a second focus frame, wherein the size of the second focus frame is smaller than that of the first focus frame.

Based on the above process, a reduction factor equal to the second setting factor and greater than 1 may be preset. In S902, the size of the second focus frame may be determined according to the set reduction factor such that the reduction factor of the size of the second focus frame compared to the size of the first focus frame is equal to the second set factor.

Taking the first focus frame in fig. 3 as an example, the side length of the first focus frame is l, the reduction factor is 2 times, and the magnification mode is to magnify the first focus frame with the center as a base point. The user clicks the volume-reducing key on the remote controller, responds to the volume-reducing instruction corresponding to the volume-reducing key, deletes the first focus frame of the display interface, reduces the first focus frame by dividing the first focus frame by 2 on the basis of the side length l of the first focus frame, and redraws the second focus frame to obtain a second focus frame as shown in fig. 10, wherein the side length is 0.5l. In this manner, if the user clicks the volume down button on the remote control again, the interface displays a square focus box with a side length of 0.25 l. It should be noted that fig. 10 shows the first focus frame in a dashed line frame manner, so as to compare the positions of the focus frames before and after the zoom-out, and in the specific implementation, the first focus frame is deleted before the second focus frame is displayed.

In a possible implementation manner, a focus frame reduction multiple can be additionally set, wherein the reduction multiple is equal to a fourth setting multiple and is used when the focus frame is reduced when the user presses the volume reduction key for a long time, the fourth setting multiple is different from the second setting multiple in size, for example, the fourth setting multiple can be smaller than the second setting multiple, so that the size of the focus frame can be slowly reduced through long pressing the volume reduction key on the remote controller from the visual experience of the user, the flexibility of size control of the focus frame can be improved, and the user experience can be improved. Specifically, if the user presses the volume-down key on the remote controller for a long time, the focus frame is drawn at the focus frame reduction factor set additionally. Further, the currently drawn focus frame may be displayed only when the user lifts the volume-down key. Because the volume increasing key is pressed for a long time, the volume increasing key instruction is sent to the smart television at a certain time interval, and the smart television responds based on the received volume key instruction of each key, when the method is adopted, the longer the volume decreasing key is pressed for a long time, the smaller the size of the displayed focus frame is, and the user can obtain the focus frame with a corresponding reducing effect by controlling the time length for pressing the volume decreasing key for a long time.

When the size of the focus frame is equal to that of the minimum focus frame and the user operates the volume reduction key on the remote controller, the user interface keeps the focus frame and presents prompt information to prompt that the size of the focus frame reaches the minimum value and cannot be reduced.

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

The following describes the flow shown in fig. 9 in detail by taking a square focus frame as an example and combining the user interface shown in fig. 3 and the system architecture shown in fig. 8 as an example.

Taking an image processing application as an example, when the application is installed, it registers a key value that it wants to monitor with the monitoring control service in the application framework layer 802, and stores the key value registered by the application and related monitoring information in the database of the monitoring control service.

Table 2: monitoring information corresponding to volume-down key registered by image processing application program

Application name	Key value	Action	Whether or not to distribute
				Image processing application program	Key_vol_dec	Response to	False

The remote controller keys registered by the image processing application program comprise volume reduction keys, and the Key value of the volume reduction keys is represented as Key _ vol _ dec. The Action indicates that a response needs to be performed if an event corresponding to the key value is received. False indicates that downward distribution is not continued if an event corresponding to the key value is received, that is, the application only executes a response corresponding to the key value and does not execute a default response of the key value. For example, the image processing application program receives the key value event and only performs the zoom-out operation of the focus frame without performing the default volume-down operation.

A wireless signal (volume-reducing Key instruction) generated after a user operates a volume-reducing Key on a remote controller is read by an Input Device Driver in an intelligent television system architecture, and the signal is processed by the Input Device Driver to obtain a volume-reducing event (the event comprises a Key value Key _ vol _ dec) and sent to a monitoring control service in an application framework layer 802; the interception control service determines whether the current application (image processing application) registers the key value and registers as responding to the key value according to the interception information (shown in table 2) registered by the application, and if so, sends the volume reduction event to the image processing application in the application layer 803; the image processing application performs corresponding processing, in this example, a zoom-out operation of the focus frame, in accordance with the received volume-down event. And when the focal point frame reducing operation is executed, the monitoring control service of the application framework layer determines that the volume reducing event is not distributed any more according to the key value registered by the application program and the related information, so that the focal point frame reducing processing operation is completed.

Referring to fig. 11, a flowchart of a method for implementing zoom-in or zoom-out of a user interface focus box through a confirmation key on a remote controller is provided for the present disclosure.

The method comprises the following steps:

s1101: and receiving a confirmation key command which is generated by a confirmation key on the remote controller and acts on the first focus frame.

S1102: acquiring zooming instruction information according to the received confirmation key instruction, judging whether the zooming instruction information is used for instructing the focus frame zooming-in operation or the focus frame zooming-out operation, if the zooming instruction information is the focus frame zooming-in operation, executing S1103, otherwise, executing S1104.

S1103: and deleting the first focus frame and displaying a second focus frame according to the zooming indication information as the zooming operation, wherein the size of the second focus frame is larger than that of the first focus frame.

In S1103, the size of the second focus frame may be determined according to the first setting factor such 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 setting factor.

In a possible implementation manner, the user presses the confirmation key for a long time, the focus frame can be enlarged according to the third setting multiple, and the focus frame currently drawn when the user lifts the confirmation key is displayed, so that the size of the drawn focus frame is larger than that of the first focus frame.

Optionally, if a partial edge of the first focus frame coincides with a partial boundary of a maximum boundary of the focus frame, and the zoom instruction information indicates a zoom-in operation of the focus frame, a corresponding edge of the second focus frame displayed in response to the volume increase key instruction still coincides with the partial boundary of the maximum boundary of the focus frame.

S1104: and deleting the first focus frame and displaying a second focus frame according to the zoom indication information as the zoom-out operation, wherein the size of the second focus frame is smaller than that of the first focus frame.

In S1104, the size of the second focus frame may be determined according to a second set multiple such that the reduction multiple 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 presses the confirmation key for a long time, the focus frame can be reduced according to the fourth setting multiple, and the focus frame currently drawn when the user lifts the confirmation key is displayed, so that the size of the drawn focus frame is smaller than that of the first focus frame.

The zoom instruction information in the above-described embodiment may be set by the system, for example, setting an initial value of the zoom instruction information to 0 indicating that the default zoom operation is to zoom in the focus frame, setting an initial value of the zoom instruction information to 1 indicating that the default zoom operation is to zoom out the focus frame.

In some embodiments, the initial value of the zoom instruction information is set by the system, and during the operation process, the value of the zoom instruction information may be changed according to the zoom-in and zoom-out conditions of the focus frame, so as to implement continuous change of the size of the focus frame.

For example, if the current zoom instruction information is an operation for instructing zooming in of the focus frame, after the smart television receives the enter key instruction, because the current zoom instruction information is used for instructing zooming in of the focus frame, the zoom in of the focus frame is executed, and it is determined whether the size of the second focus frame after being zoomed in is equal to the size of the maximum focus frame or the edge of the second focus frame coincides with the maximum boundary of the focus frame, if yes, it is indicated that the current focus frame has been zoomed in to the maximum degree, and the zoom instruction information is set to instruct zooming out of the focus frame. In this way, the zoom-out operation of the focus frame can be executed after receiving the confirmation key instruction acting on the focus frame again.

For another example, if the current zoom instruction information is a zoom-out operation for instructing a focus frame, after the smart television receives the enter key instruction, because the current zoom instruction information is used for instructing a zoom-out operation for the focus frame, the zoom-out operation for the focus frame is executed, and it is determined whether the size of the second focus frame after being zoomed out is equal to the size of the minimum focus frame, if so, it indicates that the current focus frame has been zoomed out to the minimum degree, and the zoom instruction information is set to instruct a zoom-in operation for the focus frame. In this way, after receiving the confirmation key instruction acting on the focus frame again, the zoom-in operation of the focus frame can be performed.

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

Taking the example that the initial value of the zoom instruction information is used to instruct the zoom-in operation of the focus frame, after receiving the enter key instruction applied to the first focus frame, it is determined whether the size of the first focus frame is equal to the size of the maximum focus frame or whether the edge of the first focus frame coincides with the maximum boundary of the focus frame, and if so, it indicates that the focus frame cannot be zoomed in any more, and therefore the first focus frame is deleted and the second focus frame is displayed according to the minimum focus frame size or the default focus frame size or the size of the initial focus frame. Wherein, the size of the initial focus frame is the size of the focus frame when the focus frame is initially generated.

Taking the initial value of the zoom instruction information as an example for instructing the zoom-out operation of the focus frame, after receiving the confirmation key instruction applied to the first focus frame, it is 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 first focus frame coincides with the minimum boundary of the focus frame, and if so, it indicates that the focus frame cannot be zoomed out any more, so that the first focus frame is deleted and the second focus frame is displayed according to the maximum focus frame size or the default focus frame size or the size of the initial focus frame.

The following describes the flow shown in fig. 11 in detail by taking a square focus frame as an example and combining the user interface shown in fig. 3 and the system architecture shown in fig. 8 as an example.

Table 3: monitoring information corresponding to confirmation key registered by image processing application program

Application name	Key value	Action	Whether or not to distribute
				Image processing application program	Key_vol_ok	Response to	True

The remote controller keys registered by the image processing application program comprise confirmation keys, and Key values of the confirmation keys are represented as Key _ vol _ ok. And the Action indicates that a response needs to be carried out if the event corresponding to the key value is received. True indicates that the downward distribution continues after receiving the event corresponding to the key value, i.e. the application program executes not only the response corresponding to the key value but also the default response of the key value. For example, after receiving the key value event, the image processing application executes a default confirmation operation after executing a zoom-out or zoom-in operation of the focus frame.

A wireless signal (confirmation Key instruction) generated after a user operates a confirmation Key on a remote controller is read by an Input Device Driver (Input Device Driver) in the smart television system architecture, the Input Device Driver processes the signal to obtain a confirmation event (the event comprises a Key value Key _ vol _ ok) and sends the confirmation event to a monitoring control service in an application framework layer 802; the listening control service determines whether the current application (image processing application) registers the key value and registers as a response to the key value according to the monitoring information (shown in table 3) registered by the application, and if so, sends the confirmation event to the image processing application in the application layer 803; the image processing application determines whether the event is an enlargement operation or a reduction operation based on the received confirmation event, and performs corresponding processing, in this example, determining that the event is an enlargement operation. And when the focal frame amplification operation is executed, the related system service in the application framework layer needs to be called, and after the focal frame amplification operation is executed, the monitoring control service of the application framework layer distributes the confirmation event according to the key value registered by the application program and the related information, so that the focal frame amplification operation corresponding to the confirmation key is completed.
