Fig. 1 is a block diagram of a vehicle-mounted device according to an embodiment of the present invention. Please refer to FIG. 1, the vehicle-mounted device 100 includes a processor 110, a dashboard 120 and a storage unit 130. The processor 110 is coupled to the dashboard 120 and the storage unit 130.

The processor 110 is, for example, a central processing unit (CPU), a physical processing unit (PPU), a programmable microprocessor (Microprocessor), an embedded control chip, and a digital signal processor (Digital Signal Processor). Processor, DSP), Application Specific Integrated Circuits (ASIC) or other similar devices.

The storage unit 130 is, for example, any type of fixed or removable random access memory (Random Access Memory, RAM), read-only memory (Read-Only Memory, ROM), flash memory (Flash memory), hard disk Dish or other similar device or a combination of these devices. The storage unit 130 includes a picture database 131, and the picture database 131 includes a plurality of picture files. The storage unit 130 also includes one or more code snippets. After the code snippets are installed, the processor 110 executes the following display method applied to the dashboard.

Fig. 2 is a flowchart of a display method applied to a dashboard according to an embodiment of the present invention. Please refer to FIG. 1 and FIG. 2. In step S205, a picture database 131 is provided. The picture database 131 includes a plurality of picture files. Here, the drawing file has a set of cut drawings, and the set of cut drawings respectively includes a plurality of pointer design drawing files, and the pointer design drawing files respectively have pointers corresponding to different extending directions.

For example, FIG. 3 is a schematic diagram of a pointer design drawing file according to an embodiment of the present invention. Fig. 4 is a schematic diagram of a set of cuts according to an embodiment of the present invention. FIG. 3 shows N pointer design drawing files 301_1 to 301_N included in a set of cut drawings. The pointers of the N pointer design drawing files 301_1 to 301_N respectively correspond to different directions. In FIG. 4, N pointer design drawing files 301_1 to 301_N included in a group of cut drawings are displayed at the same time. Here, a pointer design drawing file corresponds to an angle. Take the pointer of the speedometer as an example, suppose the highest speed of the speedometer is 190 km/h, and the unit is 1 km/h. Using this method of design, you can cut out the corresponding angles that point to 0～190 km/h. Of 191 pointer design drawings. The pointer of each pointer design file in a group of cuts corresponds to an angle.

In this embodiment, the processor 110 may further determine the number of image files included in a set of cut images stored in the image database 131 according to the set parameters. The setting parameter is, for example, at least one of acceleration performance, exhaust volume, energy consumption, and operation mode of the engine. In addition, the processor 110 may also divide the speedometer into multiple speed ranges, and the number of graph files corresponding to each speed range is the same or different.

For example, the processor 110 targets the speed range 0-20km/h, the speed range 20-40 km/h, the speed range 40-60 km/h, the speed range 60-100 km/h, and the speed range according to the acceleration performance of the engine. Set the number of graph files for each speed zone in the range of 100～180 km/h. For example, the number of graph files in the speed range 0-20km/h is 20, the number of graph files in the speed range 20-40 km/h is 40, and the number of graph files in the speed range 40-60 km/h is 40. The number of graph files in the 60-100 km/h section is 40, and the number of graph files in the speed section 100-180 km/h is 40. Of course, the above is only an example and not a limitation.

In addition, the number of graphics files can also be determined according to the acceleration performance. For example, for vehicles with high acceleration performance, because they can quickly accelerate to the desired speed, for lower speed ranges (for example, 0-60 km/h), the pointer change does not need to be too precise. But you can set fewer graphics files. For example, the number of graph files in the speed range 0-20km/h is 10, the number of graph files in the speed range 20-40 km/h is 20, and the number of graph files in the speed range 40-60 km/h is 20. The number of graph files in the 60-100 km/h section is 40, and the number of graph files in the speed section 100-180 km/h is 40. Of course, the above is only an example and not a limitation.

For another example, for vehicles with low acceleration performance, it takes a while to accelerate to the desired speed. Therefore, more graphic files can be set in a lower speed range (for example, 0-60 km/h), so that the pointer is The changes can be more subtle. For example, the number of graph files in the speed range 0-20km/h, 20-40 km/h, 40-60 km/h, 60-100 km/h, and 100-180 km/h are all set to 40. Of course, the above is only an example and not a limitation.

In addition, the image file of the image database 131 may also include two or more than two sets of cut images. The user can design as desired, and input the designed multiple sets of cut images into the image database 131 of the vehicle-mounted device 100. For example, the drawing file includes a first set of cuts and a second set of cuts, and the first set of cuts and the second set of cuts respectively include a plurality of pointer design drawing files, and these pointer design drawing files respectively correspond to different extension directions Pointer. The first group of cut pictures and the second group of cut pictures are pointer design files of different styles. The processor 110 may determine, based on the setting instruction, to fetch the pointer design image file in the first group of cut images from the image database 131 or fetch the pointer design image file in the second group of cut images from the image database 131. The setting instruction can be pre-set or input by the user. For example, the pointer style of each display content (for example: speedometer, fuel gauge, water tank temperature gauge, engine temperature gauge, etc.) displayed in the dashboard 120 may be set in the in-vehicle device 100 in advance. Alternatively, the user can also set various pointer styles in the dashboard 120 by himself.

For example, FIG. 5 is a schematic diagram of a pointer pattern according to an embodiment of the invention. The pointer styles 501, 503, 505, 507, and 509 are listed in Figure 5. Five sets of cut pictures can be set in the picture database 131 for the five pointer styles 501, 503, 505, 507, and 509. The processor 110 sets a set of cut images corresponding to each display content based on the setting instruction. The pointer style used for each display content can be the same or different.

After the image database 131 is established, in step S210, the processor 110 reads the driving data. In step S215, the processor 110 retrieves a picture file corresponding to the driving data from the picture database 131 according to the driving data. After the processor 110 obtains the driving data, it will retrieve a picture file corresponding to the driving data from the picture database 131. For example, the driving data is at least one of driving speed, fuel level, water tank temperature, and engine temperature. Taking the driving data as the driving speed as an example, after the processor 110 obtains that the current driving speed is 40 km/h, it will retrieve the 40 km from the set of cuts in the image database 131 corresponding to the speedometer display. An image file corresponding to /h.

After that, in step S220, the processor 110 displays the extracted image file on a specific position corresponding to the dashboard 120. For example, assuming that the driving speed is 40 km/h, the processor 110 retrieves from the picture database 131 the graph file corresponding to the direction pointed by the pointer to 40 km/h, and displays the retrieved graph file on the dashboard 120 at the speed per hour The table corresponds to a specific location pointing to 40 km/h.

In addition, the processor 110 may change the pointer style presented by the speedometer according to the vehicle speed. FIG. 6 is a schematic diagram of a speedometer using a pointer style according to an embodiment of the present invention. FIG. 7 is a schematic diagram of a speedometer using another pointer style according to an embodiment of the present invention. For example, when the current speed is less than or equal to 100 km/h, the pointer design drawing file of the pointer style 509 as shown in FIG. 6 is displayed. When the current speed is greater than 100 km/h, the pointer design drawing file of the pointer style 507 shown in Figure 7 is displayed.

In addition, the design of the dashboard 120 can not only have a fixed elliptical border, but also have other options. For example, the user can input his own design drawing file or favorite drawing file as the boundary map of the dashboard 120, as shown in FIG. 8. FIG. 8 is a schematic diagram of a boundary map of a customized dashboard according to an embodiment of the present invention.

In addition, in other embodiments, the image file further includes at least one set of images, and the set of images includes a plurality of cutouts, and a stereoscopic visual effect can be presented by continuously displaying the multiple cutouts in the set of images. Here, the group pictures can be stored in the picture database 131 in advance. In addition, the existing image files in the image database 131 can also be used to generate multiple cut images to form a set of images. For example, the processor 110 may select one of the image files from the image database 131 as a reference image file, scale the reference image file according to requirements to obtain multiple cut images of different sizes, or rotate the reference image file according to requirements to obtain Multiple cuts with different directions.

In step S220 shown in FIG. 2, the processor 110 may further continuously display the cut pictures included in the group picture at a specific position. The processor 110 can change or stack different cut images according to different times, speeds and directions, thereby creating a three-dimensional near-and-far stereoscopic visual effect. In addition, a playback speed can be further preset, or the playback speed can be determined according to the currently obtained driving data, so as to change or stack different cuts according to the playback speed. For example, the faster the driving speed, the faster the playback speed, and the slower the driving speed, the slower the playback speed. Of course, this is only an example and not a limitation.

In addition, the processor 110 may number the group pictures, and number the cut pictures in the group pictures, and set the usage scenarios corresponding to the group pictures according to requirements. For example, suppose the group picture number includes 3D_1 and 3D_2, the group picture number 3D_1 includes the cut picture numbers 2D_1～2D_10, the group picture number 3D_2 includes the cut picture numbers 2D_11～2D_20, the group picture number 3D_1 corresponds to the night mode, and the group picture number 3D_2 corresponds to Day mode. When the dashboard 120 is set to the daytime mode, the processor 110 will select the group picture number 3D_2 to display the cut pictures corresponding to the cut picture numbers 2D_11 to 2D_20 in the position corresponding to the dashboard 120. When the dashboard 120 is set to the night mode, the processor 110 selects the group picture number 3D_1 to display the slices corresponding to the slice numbers 2D_1 to 2D_10 in the position corresponding to the dashboard 120.

FIG. 9 is a schematic diagram of a group diagram according to an embodiment of the present invention. Referring to FIG. 9, the group picture 900 includes a cut picture 901 to a cut picture 906. Here, the sizes of the cut 901 to the cut 906 are different, and the cut 901 to the cut 906 present a gradually increasing stereoscopic effect viewed from the viewing angle direction D1. Based on the playback speed, the processor 110 presents a stereoscopic visual effect by continuously displaying the cut 901 to cut 906 in the group of pictures 900 at a specific position of the dashboard 120, for example, based on the size, the smallest cut 901 The display starts, and then the cut 902, the cut 903, the cut 904, the cut 905, and the cut 906 are successively displayed.

Here, the cut 901 to cut 906 can be created in the image database 131 in advance, or the cut 901 to cut 906 can be generated based on the three-dimensional effect to be presented according to a reference image file. In addition, the number of cut images included in the group image 900 can be dynamically determined according to the resolution.

FIG. 10 is a schematic diagram of a group diagram according to an embodiment of the present invention. Referring to FIG. 10, the set of pictures 1000 includes cut pictures 1001 to 1005. Here, the dimensions of the cut 1001 to 1005 are different. Based on the playback speed, the processor 110 starts to display the smallest cut 1001 in a specific position on the dashboard 120, and then continues to display cut 1002, cut 1003, cut 1004, and cut 1005, thereby showing The gradually increasing stereoscopic effect is viewed from the viewing angle direction D2. Here, the cut 1001 to the cut 1005 can be created in the image database 131 in advance, and the cut 1001 to the cut 1005 can also be generated based on the three-dimensional effect to be presented according to a reference image file. In addition, the number of cut images included in the group image 1000 can be dynamically determined according to the resolution.

FIG. 11 is a schematic diagram of a group diagram according to an embodiment of the present invention. Referring to FIG. 11, the group of pictures 1100 includes cut 1101 to cut 1112, and cut 1101 to cut 1112 show the effect of rotating in a clockwise direction. In this embodiment, the directions of the patterns (ie, “99”) of the cut 1101 to 1112 are different. In other words, after the two slices overlap each other, they form a rotating image relationship based on the same center point. For example, looking at the cut 1101 and the cut 1102, the pattern "99" of the cut 1102 is obtained by rotating the pattern "99" of the cut 1101 by an angle clockwise; take the cut 1101 and the cut 1112 to see , The pattern "99" of the cut image 1112 is obtained by rotating the pattern "99" of the cut image 1101 by an angle counterclockwise. In this way, cuts 1101 to 1112 with different pattern directions can be obtained. Here, the cut 1101 to the cut 1112 can be created in the image database 131 in advance, or the cut 1101 to the cut 1112 can be generated based on the three-dimensional effect to be presented according to a reference image file. In addition, the number of cut images included in the group image 1100 can be dynamically determined according to the resolution.
