[0027] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0028] According to an embodiment of this application, an image scaling method embodiment is provided. It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Furthermore, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order than that shown here.

[0029] This embodiment provides an image scaling method that can be used in computer devices such as computers, cloud servers, and mobile terminals. Figure 1 is a flowchart illustrating the image scaling method according to an embodiment of this application. As shown in Figure 1, the process includes the following steps:

[0030] In step S101, an instruction to reduce or increase the size of an image frame is received, and the ratio of the height of the adjusted image frame indicated by the instruction to the height of the target vehicle's display screen is calculated.

[0031] Instructions indicating whether to zoom in or out on an image frame can be generated by a unit that generates and sends the instructions.

[0032] As an example, a user speaks a voice indicating whether to zoom in or out on an image frame. The unit that generates and sends the instruction responds to the voice indicating whether to zoom in or out on the image frame and generates an instruction indicating whether to zoom in or out on the image frame.

[0033] As an example, when a user indicates to zoom in or out on an image frame on the dialog service flow interface, the unit for generating and sending instructions generates instructions to zoom in or out on the image frame in response to the indication to zoom in or out.

[0034] In step S102, the original image frame, including the information to be displayed in the dialogue service flow interface, is scaled down 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.

[0035] The dialogue service flow interface is used to display relevant information about the dialogue service. Specifically, it displays the call results corresponding to the atomic service functions used to achieve the target intent, and can also display a text chat window, a message send button, and other elements. Raw image frames represent the image content to be displayed in the dialogue service flow interface; this interface is displayed on the target vehicle's infotainment screen.

[0036] The target image frame can represent the image frame that will ultimately be displayed to the user on the dialog service flow interface. Specifically, if the ratio of the height of the adjusted image frame to the height of the target vehicle's display screen, indicated by the operation instruction to zoom in or out, is greater than the ratio of the height of the original image frame to the height of the target vehicle's display screen, then the original image frame, including the information that needs to be displayed in the dialog service flow interface, is zoomed in.

[0037] If the ratio of the height of the adjusted image frame to the height of the target vehicle's display screen in the operation instruction indicating to reduce or enlarge the image frame size is less than the ratio of the height of the original image frame to the height of the target vehicle's display screen, then the original image frame, including the information that needs to be displayed in the dialog service flow interface, is reduced.

[0038] The height of the target image frame for the information to be displayed in the dialogue service flow interface has an adjusted image frame height. The ratio of the width of the target image frame for the information to be displayed in the dialogue service flow interface to the width of the target vehicle's display screen can be: the ratio of the adjusted image frame height to the height of the target vehicle's display screen, which is an operation instruction indicating whether to zoom in or out on the image frame.

[0039] In this embodiment of the application, the original image frame including target information is reduced or enlarged according to the ratio of the adjusted image frame height to the height of the target vehicle's display screen as indicated by the operation instruction, to obtain a target image frame including information that needs to be displayed in the dialogue service flow interface. The target image frame is then displayed in the dialogue service flow interface so that the target image frame does not globally cover the vehicle's display screen, thereby not obscuring the original application interface content and improving the user's convenience in obtaining information.

[0040] In one possible implementation, step S102 above, which involves scaling down or up the original image frame containing the information to be displayed in the dialogue service flow interface according to a scale, includes:

[0041] Step a1: Based on the ratio, determine the target size corresponding to each scaling operation in multiple scaling operations or the target size corresponding to each zoom-in operation in multiple zoom-out operations.

[0042] During the scaling process of the original image frame, the target image frame can be reached through a single scaling operation or through multiple scaling operations. In other words, the process of scaling from the original image frame to the target image frame involves gradually shrinking or enlarging the original image frame. Specifically, since the number of scaling operations can be determined after establishing a specific ratio, and after determining the ratio between the adjusted image frame height indicated by the operation and the height of the target vehicle's display screen, the target size of each scaling operation can be determined based on the number of scaling operations.

[0043] In one possible implementation, the target size of the image frame is the same each time it is scaled down or scaled up. For example, the image frame is scaled down by 1 / 6 the first time, and also by 1 / 6 the second time. As another example, the image frame is scaled up by 1 / 6 the first time, and also by 1 / 6 the second time.

[0044] In one possible implementation, the target size of the image frame is different each time it is scaled down or scaled up. For example, the first time the image frame is scaled down by 1 / 6, and the second time by 1 / 3. Another example: the first time the image frame is scaled up by 1 / 6, and the second time by 1 / 3.

[0045] In one possible implementation, a portion of the target size of the image frame is the same in each scaling down or scaling up. For example: the first scaling down of the image frame is 1 / 6, the second is 1 / 3, and the third is 1 / 6. Another example: the first scaling up of the image frame is 1 / 6, the second is also 1 / 3, and the third scaling down is 1 / 6.

[0046] Step a2 involves performing multiple zoom-out or zoom-in operations. The zoom-out operation includes: zooming out of the image frame targeted by the zoom-out operation, obtaining the next image frame targeted by the zoom-out operation or the target image frame, and displaying the resulting image frame. The image frame targeted by the first zoom-out operation is the original image frame. The zoom-in operation includes: zooming out of the image frame targeted by the zoom-in operation, obtaining the next image frame targeted by the zoom-in operation or the target image frame, and displaying the resulting image frame. The image frame targeted by the first zoom-in operation is the original image frame.

[0047] After determining the target size for each zoom-out or zoom-in operation, the computer device can perform multiple zoom-out or zoom-in operations. Each time a zoom-out operation is performed, the image frame targeted by the previous zoom-out operation is reduced in size to obtain the image frame targeted for the next zoom-out operation. The zoom-out operation continues based on the image frame targeted by the next zoom-out operation until the target image frame for the next zoom-out operation is obtained. Similarly, each time a zoom-out or zoom-in operation is performed, the image frame targeted by the previous zoom-out operation is enlarged to obtain the image frame targeted for the next zoom-in operation. The zoom-in operation continues based on the image frame targeted by the next zoom-in operation until the target image frame for the next zoom-in operation is obtained. After each zoom-out or zoom-in operation, the obtained image frame needs to be displayed.

[0048] As an example, perform a scaling down operation on image frame A, reducing it to 1 / 6 of its original size to obtain image frame B. Then perform a scaling down operation on image frame B, reducing it to 1 / 6 of its original size to obtain image frame C. Finally, perform a scaling down operation on image frame C, reducing it to 1 / 6 of its original size to obtain the target image frame.

[0049] In one possible implementation, the computer device can perform the scaling down or scaling up operation based on the original image frame, after determining the target size corresponding to each scaling down operation or the target size corresponding to each scaling up operation in multiple scaling down operations. That is, in each scaling down and scaling up operation, the original image frame is used as the reference to scale down or scale up the original image frame.

[0050] As an example, a magnification operation is performed on the original image frame M. The first magnification operation can be to magnify the original image frame M by 1 / 6, and the second magnification operation can be to magnify the original image frame M by 1 / 3, thus obtaining the target image frame.

[0051] In the embodiments of this application, by continuously performing multiple zoom-out or zoom-in operations, and each operation is performed proportionally, the changes between image frames are smooth, avoiding sudden changes in image size, and making the entire scaling process look more natural and fluid.

[0052] At the same time, since the resulting image frame is displayed immediately after each zoom-out or zoom-in operation, users can clearly see the process of image size change, enhancing visual continuity and making it easier for users to understand the effect of the current operation.

[0053] In one possible implementation, step S102 above, which involves scaling down or up the original image frame containing the information to be displayed in the dialogue service flow interface according to a scale, includes:

[0054] Step b1: Obtain multiple interface elements of the original image frame of the information displayed in the dialogue service flow interface.

[0055] Interface elements are the basic components that make up the dialog service flow interface. First, it's necessary to identify the multiple interface elements contained within the dialog service flow interface. Then, extract the original image frames containing the information to be displayed from the dialog service flow interface. Finally, associate the identified interface elements with the extracted original image frames. Specifically, the position and size of each interface element within the image frame can be determined.

[0056] Step b2: Based on the scale, zoom in or out on the interface elements of the original image frame, including the information that needs to be displayed in the dialog service flow interface.

[0057] Calculate the new size of each interface element based on the proportions. Adjust the size of each interface element according to the calculated new size. After resizing, it may be necessary to rearrange the interface elements so that they are displayed correctly in the dialog service flow interface.

[0058] In this embodiment of the application, by acquiring multiple interface elements of the original image frame and scaling them down or up, fine control over the interface layout can be achieved, allowing the size and position of each element to be flexibly adjusted according to the specific needs of the dialogue service flow interface, so as to optimize the information display effect.

[0059] In one possible implementation, displaying the target image frame in the dialogue service flow interface in step S102 above includes:

[0060] Display the target image frame in the target area of ​​the target vehicle's dialogue service flow interface; wherein, the target area is the area of ​​the target vehicle's dialogue service flow interface other than the area displaying the task information of the task currently being performed by the target vehicle.

[0061] The target vehicle's current task can be navigation. The task information for this navigation task includes the navigation route. This information is displayed as a scaled-down version in the target area of ​​the target vehicle's display screen, such as the vehicle's infotainment screen. The task information for the target vehicle's current navigation task is also displayed in other areas of the target vehicle's display screen, excluding the target area.

[0062] In this embodiment, target information displayed via zooming is shown in the target area of ​​the target vehicle's display screen, while task information of the currently executing task is displayed in other areas of the target vehicle's display screen. This allows the user inside the target vehicle to see both the information displayed via zooming and the task information of the currently executing task. This avoids the situation where only the information displayed via zooming is shown, preventing the user inside the target vehicle from seeing the task information of the currently executing task, thus degrading the user experience.

[0063] In one possible implementation, displaying the target image frame in the dialog service flow interface in step S102 above includes: scaling down or up the original image frame, including the information to be displayed in the dialog service flow interface, according to the scale, through the page root element of the system layer.

[0064] The root element of the system layer can be a component shared by all applications (APP). The computer device adds the page element after scaling down or enlarging the original image frame of the information displayed in the dialog service flow interface to the root element of the system layer, and the target image frame is formed through the root element.

[0065] Please refer to Figures 2 and 3. Figure 2 is an architecture diagram of an image scaling system provided according to an embodiment of this application, and Figure 3 is an effect diagram of an image scaling method provided according to an embodiment of this application.

[0066] Image scaling methods can be applied to the Android system. The system-level page root element, DecorCaptionView, can act as the scaling component of the image scaling system. SurfaceControl scales the information displayed in the dialog service flow interface, specifically by calculating the scaling ratio. The contentroot is a starting point in the layout or view structure. When its content changes, the application within the dialog service flow interface recalculates the layout and adjusts the size and position of the original image frames. The Android system provides applications with drawing surfaces on which they perform drawing operations. In images, the actual size of the surface remains constant, but scaling is achieved through SurfaceControl to present different visual effects. The size of the task is fixed at the screen height; regardless of content changes, the task's height remains constant. During layout, the size and position of DecorView are calculated and adjusted based on the page root element.

[0067] Specifically, in the Android system, scaling the information displayed in the dialog service flow interface allows it to be visually presented at different sizes. Scaling does not change the physical size of the surface, only its displayed size on the screen. Based on changes in the content of page elements, these elements are added to the root element of the system layer, and the root element is used to construct the target image frame.

[0068] In this embodiment, when the size of the image frame to be displayed is adjusted, the module of the application layer for displaying the image frame notifies the kernel module of the operating system for adjusting the image frame. The kernel module of the operating system then modifies the configuration item of the image frame size from the original size to the adjusted size. Adjusting the size of the image frame to be displayed has a large overhead. This notification and modification will cause the page to refresh during the scaling process, resulting in page jumping and the corresponding lifecycle methods being called back due to the page refresh, which will adversely affect the performance of the vehicle system.

[0069] This embodiment also provides an image scaling device for implementing the above embodiments and preferred embodiments; details already described will not be repeated. As used below, the term "module" can refer to a combination of software and / or hardware that performs a predetermined function.

[0073] In one possible implementation, the operation module 402 is used to display a target image frame in a target area of ​​the target vehicle's dialogue service flow interface; wherein, the target area is the area of ​​the target vehicle's dialogue service flow interface other than the area displaying the task information of the task currently being performed by the target vehicle.

[0074] In one possible implementation, operation module 402 is used to scale the original image frame, including the information to be displayed in the dialog service flow interface, by zooming in or out through the page root element of the system layer according to a ratio.
