[0025] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0026] According to an embodiment of the present invention, an embodiment of an image scaling method is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0027] In this embodiment, an image scaling method is provided, which can be used in computer devices, such as computers, cloud servers, mobile terminals, etc. Figure 1 is a flow chart of an image scaling method according to an embodiment of the present invention. Figure 1 As shown, the process includes the following steps:

[0028] In step S101 , an instruction for reducing or enlarging the size of an image frame is received, and a ratio of the height of the image frame adjusted as indicated by the instruction to the height of a display screen of a target vehicle is calculated.

[0029] The instruction to instruct to reduce or enlarge the size of the image frame may be generated by a unit for generating and sending instructions.

[0030] As an example, the user speaks a voice instructing to enlarge or reduce the size of the image frame, and the unit for generating and sending instructions generates an instruction instructing to reduce or enlarge the size of the image frame in response to the voice instructing to enlarge or reduce the size of the image frame.

[0031] As an example, a user indicates on the dialogue service flow interface to reduce or enlarge the size of an image frame, and the unit for generating and sending instructions generates an instruction to reduce or enlarge the size of the image frame in response to the indication to enlarge or reduce the size of the image frame.

[0032] In step S102, the original image frame including the information to be displayed in the dialogue service flow interface is reduced or enlarged according to the ratio to obtain a target image frame including the information to be displayed in the dialogue service flow interface, and the target image frame is displayed in the dialogue service flow interface.

[0033] The dialogue service flow interface is used to display the relevant information of the dialogue service. The dialogue service flow interface displays the call results corresponding to the atomic service functions used to achieve the target intention, and can also display elements such as a text chat window and a button for sending a message. The original image frame can represent the image screen that needs to be displayed in the dialogue service flow interface; the dialogue service flow interface is displayed by the vehicle screen of the target vehicle.

[0034] The target image frame may represent an image frame that is ultimately displayed to the user on the dialogue service flow interface. Specifically, if the ratio of the height of the adjusted image frame indicated by the operation indicating the reduction or enlargement of the size of the image frame to the height of the display screen of the target vehicle is greater than the ratio of the height of the original image frame to the height of the display screen of the target vehicle, the original image frame including the information to be displayed in the dialogue service flow interface is enlarged.

[0035] If the ratio of the adjusted image frame height to the height of the target vehicle's display screen indicated by the operation indicating reducing or enlarging the size of the image frame is smaller than the ratio of the height of the original image frame to the height of the target vehicle's display screen, the original image frame including the information that needs to be displayed in the dialogue service flow interface is reduced.

[0036] The height of the target image frame of the information to be displayed in the dialogue service flow interface has the adjusted image frame height. The ratio of the width of the target image frame of the information to be displayed in the dialogue service flow interface to the width of the display screen of the target vehicle may be: the ratio of the adjusted image frame height of the operation indication indicating the reduction or enlargement of the size of the image frame to the height of the display screen of the target vehicle.

[0037] In an embodiment of the present invention, based on the ratio of the adjusted image frame height indicated by the operation to the height of the display screen of the target vehicle, the original image frame including the target information is reduced or enlarged to obtain a target image frame including the information to be displayed in the dialogue service flow interface, and the target image frame is displayed in the dialogue service flow interface, so that the target image frame does not globally cover the vehicle's display screen, thereby not blocking the original application interface content, thereby improving the convenience of users in obtaining information.

[0038] In a possible implementation, the step S102 described above of reducing or enlarging the original image frame including the information to be displayed in the dialogue service flow interface according to the ratio includes:

[0039] Step a1: determining, according to the ratio, a target size corresponding to each zoom operation in multiple zoom operations or a target size corresponding to each zoom operation in multiple zoom operations.

[0040] In the process of scaling the original image frame, the target image frame can be reached from the original image frame through one scaling operation or through multiple scaling operations, that is, in the process of reaching the target image frame from the original image frame, the original image frame will be gradually reduced or enlarged to the target image frame. Specifically, since the number of reductions or enlargements can be obtained after determining the ratio, after determining the ratio of the height of the adjusted image frame indicated by the operation to the height of the display screen of the target vehicle, the target size of each reduction or enlargement of the image frame can be determined according to the number of reductions or enlargements.

[0041] In a possible implementation, the target size of the image frame is the same each time it is reduced or enlarged. For example, the ratio of reducing the image frame for the first time is 1 / 6, and the ratio of reducing the image frame for the second time is also 1 / 6. For another example, the ratio of enlarging the image frame for the first time is 1 / 6, and the ratio of enlarging the image frame for the second time is also 1 / 6.

[0042] In a possible implementation, the target size of the image frame is different each time it is reduced or enlarged. For example, the ratio of reducing the image frame for the first time is 1 / 6, and the ratio of reducing the image frame for the second time is 1 / 3. For another example, the ratio of enlarging the image frame for the first time is 1 / 6, and the ratio of enlarging the image frame for the second time is 1 / 3.

[0043] In a possible implementation, there are parts of the same size in the target size of each reduction or enlargement of the image frame. For example, the ratio of the image frame to be reduced for the first time is 1 / 6, the ratio of the image frame to be reduced for the second time is 1 / 3, and the ratio of the image frame to be reduced for the third time is 1 / 6. For another example, the ratio of the image frame to be enlarged for the first time is 1 / 6, the ratio of the image frame to be enlarged for the second time is also 1 / 3, and the ratio of the image frame to be reduced for the third time is 1 / 6.

[0044] Step a2, performing multiple zoom-in operations or multiple zoom-in operations. The zoom-out operation includes: zooming in on the image frame targeted by the zoom-in operation, obtaining the image frame targeted by the next zoom-in operation or the target image frame of the zoom-in operation, and displaying the obtained image frame, wherein the image frame targeted by the first zoom-in operation is the original image frame. The zoom-in operation includes: zooming in on the image frame targeted by the zoom-in operation, obtaining the image frame targeted by the next zoom-in operation or the target image frame of the zoom-in operation, and displaying the obtained image frame, wherein the image frame targeted by the first zoom-in operation is the original image frame.

[0045] After determining the target size of each zoom-in or zoom-out operation, the computer device may perform multiple zoom-in or zoom-out operations. Each time a zoom-out operation is performed, the image frame targeted by the zoom-out operation is zoomed out to obtain the image frame targeted by the next zoom-out operation of the zoom-out operation, and then the zoom-out operation is continued according to the image frame targeted by the next zoom-out operation until the target image frame targeted by the next zoom-out operation of the zoom-out operation is obtained. Each time a zoom-in operation is performed, the image frame targeted by the zoom-in operation is zoomed in to obtain the image frame targeted by the next zoom-in operation of the zoom-in operation, and then the zoom-in operation is continued according to the image frame targeted by the next zoom-in operation until the target image frame targeted by the next zoom-in operation of the zoom-in operation is obtained, and after each zoom-out operation or zoom-in operation is performed, the obtained image frame needs to be displayed.

[0046] As an example, a reduction operation is performed on image frame A, reducing image frame A to 1 / 6 of its original size to obtain image frame B, and then a reduction operation is performed on image frame B, reducing image frame B to 1 / 6 of its original size to obtain image frame C, and then a reduction operation is performed on image frame C, reducing image frame C to 1 / 6 of its original size to obtain the target image frame.

[0047] In one possible implementation, when determining a target size corresponding to each zoom-out operation among multiple zoom-out operations or a target size corresponding to each zoom-in operation among multiple zoom-in operations, the computer device may perform a zoom-out operation or a zoom-in operation according to the original image frame, that is, during each zoom-out operation and zoom-in operation, the original image frame is used as a reference to zoom in or zoom out on the original image frame.

[0048] As an example, a magnification operation is performed on the original image frame M. The first magnification operation may be to magnify the original image frame M by 1 / 6, and the second magnification operation may be to magnify the original image frame M by 1 / 3, to obtain a target image frame.

[0049] In the embodiment of the present invention, by continuously performing multiple reduction or enlargement operations, and each operation is performed in proportion, the changes between image frames are smooth, and sudden changes in image size are avoided, making the entire scaling process look more natural and smooth.

[0050] At the same time, since the resulting image frame is displayed immediately after each zoom-in or zoom-out operation, the user can clearly see the change process of the image size, which enhances visual coherence and enables the user to more easily understand the current operation effect.

[0051] In a possible implementation, the step S102 described above of reducing or enlarging the original image frame including the information to be displayed in the dialogue service flow interface according to the ratio includes:

[0052] Step b1, obtaining multiple interface elements of the original image frame of the information displayed in the dialogue service flow interface.

[0053] The interface elements may be basic components constituting the dialogue service flow interface. First, it is necessary to identify multiple interface elements contained in the dialogue service flow interface. Extract the original image frame containing the information to be displayed from the dialogue service flow interface. Associate the identified interface elements with the extracted original image frame. Specifically, the position and size of each interface element in the image frame may be determined.

[0054] Step b2: reducing or enlarging the interface elements of the original image frame including the information to be displayed in the dialogue service flow interface according to the ratio.

[0055] According to the ratio, calculate the new size of each interface element, and adjust the size of each interface element according to the calculated new size. After adjusting the size, it may be necessary to rearrange the interface elements so that the interface elements are displayed correctly in the dialogue service flow interface.

[0056] In an embodiment of the present invention, by acquiring multiple interface elements of the original image frame and reducing or enlarging them, fine control of the interface layout can be achieved, so that the size and position of each element can be flexibly adjusted according to the specific needs of the dialogue service flow interface to optimize the information display effect.

[0057] In a possible implementation, displaying the target image frame in the dialogue service flow interface in the above step S102 includes:

[0058] The target image frame is displayed in a target area of ​​the dialogue service flow interface of the target vehicle; wherein the target area is the area of ​​the dialogue service flow interface of the target vehicle excluding the area displaying the task information of the task currently being executed by the target vehicle.

[0059] The currently executed task of the target vehicle may be a navigation task. The task information of the currently executed navigation task of the target vehicle includes a navigation route. The information is displayed as zoomed information in a target area of ​​a display screen of the target vehicle, such as a vehicle screen of the target vehicle. The task information of the currently executed navigation task of the target vehicle is displayed in other areas of the display screen of the target vehicle except the target area.

[0060] In the embodiment of the present invention, the target information displayed by the zoom operation is displayed in the target area of ​​the display screen of the target vehicle, and the task information of the task currently being executed by the target vehicle is displayed in other areas of the display screen of the target vehicle except the target area, so that the user in the target vehicle can see both the information displayed by the zoom operation and the task information of the task currently being executed by the target vehicle. The following situation can be avoided: only the information displayed by the target operation is displayed, and the user in the target vehicle cannot see the task information of the task currently being executed, resulting in a reduction in the user experience of the user in the target vehicle.

[0061] In one possible implementation, displaying the target image frame in the dialogue service flow interface in the above step S102 includes: reducing or enlarging the original image frame including the information to be displayed in the dialogue service flow interface through the page root element of the system layer according to the ratio.

[0062] The page root element of the system layer can be a component shared by all applications (Application, APP). The computer device adds the page element after reducing or enlarging the original image frame of the information displayed in the dialogue service flow interface to the page root element of the system layer, and constructs the target image frame through the page root element.

[0063] Please refer to Figure 2 and Figure 3 , Figure 2 is an architecture diagram of an image scaling system provided according to an embodiment of the present invention, Figure 3 It is a rendering of the image scaling method provided according to an embodiment of the present invention.

[0064] The image scaling method can be applied to the Android system. Among them, the page root element DecorCaptionView of the system layer can be used as the scaling component of the image scaling system. SurfaceControl scales the information displayed in the dialog service flow interface, specifically, it can calculate the scaling ratio. Contentroot is a starting point in the layout or view structure. When its content changes, the application in the dialog service flow interface recalculates the layout and adjusts the size and position of the original image frame. The Android system provides a drawing surface (Surface) for the application, and the application performs drawing operations on it. In the picture, the actual size of the surface remains unchanged, but it is scaled by surfacecontrol to present different visual effects. The size of task is fixed to the screen height, and the height of the task remains unchanged regardless of how the content changes. During the layout process, the size and position of DecorView are calculated and adjusted according to the page root element.

[0065] Specifically, in the Android system, by controlling the information displayed in the dialog service flow interface to perform scaling operations, it can be visually presented in different sizes. The scaling operation does not change the physical size of the surface, but only changes its display size on the screen. According to the content change of the page element, the page element is added to the page root element of the system layer, and the target image frame is formed through the page root element.

[0066] In an embodiment of the present invention, when the size of an image frame to be displayed is adjusted, the module of the application layer for displaying the image frame notifies the module of the kernel of the operating system for adjusting the image frame, and the module of the kernel of the operating system for adjusting the image frame modifies the configuration item of the size of the image frame from the original size to the adjusted size. The overhead of adjusting the size of the image frame to be displayed is relatively large. The notification and modification will cause the page to refresh during the scaling process, resulting in page jumping and the corresponding life cycle method being called back due to the page refresh, which will adversely affect the performance of the vehicle computer.

[0067] In this embodiment, an image scaling device is also provided, which is used to implement the above embodiments and preferred implementation modes, and the descriptions that have been made will not be repeated.

[0070] In one possible implementation, the operation module 402 includes: an acquisition unit, used to acquire multiple interface elements of the original image frame of information displayed in the dialogue service flow interface; and a processing unit, used to reduce or enlarge the interface elements of the original image frame including the information that needs to be displayed in the dialogue service flow interface according to the ratio.

[0071] In one possible implementation, the operation module 402 is used to display the target image frame in the target area of ​​the dialogue service flow interface of the target vehicle; wherein the target area is the area of ​​the dialogue service flow interface of the target vehicle except for the area that displays the task information of the task currently being executed by the target vehicle.

[0072] In a possible implementation, the operation module 402 is used to reduce or enlarge the original image frame including the information to be displayed in the dialog service flow interface through the page root element of the system layer according to the ratio.
