For example, the application of Head-Up Displays (HUDs) is becoming increasingly popular. A Head-Up Display projects instrument-related information onto the windshield, allowing the driver to see both road conditions and instrument-related information simultaneously. Summary of the Invention

[0003] The purpose of this application is to at least partially solve one of the aforementioned technical problems.

[0004] Therefore, the first objective of this application is to propose a display control method for an in-vehicle head-up display (HUD).

It can enrich the projection content and display effect of the HUD projection display area, thereby improving the user experience.

[0005] The second objective of this application is to provide a display control device for a vehicle head-up display.

[0006] The third objective of this application is to provide a vehicle-mounted head-up display device.

[0007] The fourth objective of this application is to propose a vehicle.

[0009] To achieve the above objectives, the display control method for a vehicle head-up display device proposed in the first aspect of this application includes: detecting whether a display area needs to be refreshed, wherein the display area is an area for multiple displays of the same content; when it is detected that the display area needs to be refreshed, determining a first display content image displayed at a moment before the content refresh; determining a second display content image to be displayed when the content refresh is performed; and controlling the first display content image and the second display content image to be displayed in the display area in a ghosting manner with a preset transparency.

[0010] According to the display control method of the vehicle head-up display device according to the embodiments of this application, it can detect whether the display area needs to be refreshed. The display area is an area used to achieve multiple displays of the same content. When it is detected that the display area needs to be refreshed, the method determines the first display content image displayed before the content refresh, determines the second display content image to be displayed when the content refresh occurs, and controls the first and second display content images to be displayed in the display area with a preset transparency ghosting effect. That is, when multiple displays of certain content are needed in the display area, these contents can be displayed in the display area with a preset transparency ghosting effect. Thus, this application can project the best image visual effect in any scenario. By receiving data content and instructions through the HUD, it can achieve control over the semi-transparent display of images and the refresh of display area content, enriching the projection content and display effect of the HUD projection display area, and improving the user experience.

[0011] To achieve the above objectives, the display control device for a vehicle head-up display device proposed in the second aspect of this application includes: a content refresh detection module for detecting whether a display area needs to be refreshed, wherein the display area is an area for multiple displays of content in the same area; a first determination module for determining a first display content image displayed in the display area before the content refresh is performed when the display area is detected to need to be refreshed; a second determination module for determining a second display content image to be displayed when the display area is refreshed; and a display control module for controlling the first display content image and the second display content image to be displayed in the display area in a ghosting manner with preset transparency.

[0012] According to the vehicle head-up display device of this application embodiment, the display control device can detect whether the display area needs to be refreshed through a content refresh detection module. The display area is an area used to achieve multiple displays of the same content. When the content refresh detection module detects that the display area needs to be refreshed, the first determining module determines the first display content image displayed before the content refresh. The second determining module determines the second display content image to be displayed when the display area is refreshed. The display control module controls the first and second display content images to be displayed in the display area with a preset transparency and a ghosting effect. That is, when multiple displays of certain content are needed in the display area, these contents can be displayed in the display area with a preset transparency and a ghosting effect. Thus, this application can project the best image visual effect in any scenario. By receiving data content and instructions through the HUD, it can achieve control over the semi-transparent display of images and the refresh of the display area content, enriching the projection content and display effect of the HUD projection display area and improving the user experience.

[0026] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0027] The following description, with reference to the accompanying drawings, describes a display control method, apparatus, vehicle, and computer-readable storage medium for an in-vehicle head-up display device according to embodiments of this application.

[0028] Figure 1 This is a flowchart of a display control method for an in-vehicle head-up display device according to an embodiment of this application. It should be noted that the display control method for the in-vehicle head-up display device of this application embodiment can be applied to the display control device of the in-vehicle head-up display device of this application embodiment, and the display control device can be configured on the in-vehicle head-up display device.

[0029] It should also be noted that the vehicle head-up display device in this application embodiment can be used to receive voice command control codes sent by the vehicle multimedia system, and to project and display the parameter information provided by the corresponding vehicle electrical appliance and / or the notification information provided by the mobile terminal according to the voice command control code. For example, the parameter information provided by the vehicle electrical appliance and / or the notification information provided by the mobile terminal can be projected onto the windshield. As an example, such as... Figure 2 As shown, this vehicle-mounted head-up display (HUD) includes an LED projection light source, an LCD display screen, a heat sink, a diffuser (not shown), a projection imaging lens, a processor, a PWM dimming module, an Ethernet transceiver (TAJ1100), and multiple CAN transceivers. The LED projection light source is mounted on the heat sink and fixed to the LCD display screen. A diffuser is attached to the LCD display screen, and the light emitted by the LED projection light source is projected onto the projection imaging lens through the diffuser to form an image. The processor is connected to multiple CAN transceivers, each corresponding to a vehicle electrical component. The vehicle electrical component can send its information to the HUD for storage and display via its corresponding CAN transceiver. The PWM dimming module can be used to adjust the projection brightness of the projection module in the HUD.

[0030] For example, the processor can connect to the body controller via a CAN transceiver, and the body controller can send the status information of each door of the vehicle to the processor via the corresponding CAN transceiver and display it on the screen; another example is that the processor can connect to the instrument panel via a CAN transceiver, obtain the parameter information on the instrument panel through the CAN transceiver and display it on the screen; yet another example is that the processor can connect to a mobile terminal via an Ethernet transceiver, obtain notification messages from the mobile terminal through this connection and display them on the screen.

[0031] like Figure 1 As shown, the display control method of the vehicle head-up display device may include:

[0032] S110, detect whether the display area needs to be refreshed.

[0033] In the embodiments of this application, the display area is the display area on a vehicle head-up display device. The display area is an area used to achieve multiple displays of the same content. That is, the display area in the embodiments of this application can be understood as an area requiring multiple displays, for example, a display area requiring dual display, such as displaying both navigation intersections and navigation instructions.

[0034] In the embodiments of this application, it can be determined whether a first message is received, which can be understood as a message indicating entry into the image display area content refresh control mode. If the message is received, it is determined that the display area needs to be refreshed. If the first message is not received, but a second message is received instead, which can be understood as a message indicating entry into the normal projection display mode, it can be determined that the display area does not need to be refreshed, but directly enters the normal projection mode, that is, the content to be displayed is directly projected and displayed without adjusting the display parameters of the content to control its display effect.

[0035] S120, when it is detected that the display area needs to be refreshed, the first display content image displayed at the moment before the display area is refreshed is determined.

[0036] For example, suppose the projection module in the vehicle head-up display has three display areas: area A, area B, and area C. If it is detected that area B needs to refresh its content, it is necessary to determine the content image displayed in area B before the content refresh. For example, if the content image displayed in area B before the content refresh is navigation intersection a, then the first displayed content image can be determined to be the image corresponding to navigation intersection a.

[0037] S130, determine the second display content image to be displayed when refreshing the display area.

[0038] Optionally, when it is detected that the display area needs to be refreshed, it is also necessary to determine the second display content image to be displayed when the display area is refreshed. That is, when it is detected that the display area needs to be refreshed, it is also necessary to determine the content image to be displayed in the display area. For example, suppose the projection module in the vehicle head-up display device has three display areas, area A, area B and area C. Suppose area B is used to display navigation function information. Suppose that area B needs to display both the navigation intersection and the navigation indicator. Therefore, it can be determined that the content image displayed in area B before the content refresh is the navigation intersection a, and the display content image to be displayed when the content refresh is the navigation indicator (such as a left turn arrow).

[0039] S140, control the first display content image and the second display content image to be displayed in the display area in a ghosting manner with preset transparency.

[0040] Optionally, the display parameters of the first and second display content images are adjusted respectively, so that the first and second display content images are simultaneously displayed in the display area with a preset transparency (e.g., 50% transparency) in a ghosting manner. In embodiments of this application, the display parameters may include, but are not limited to, saturation and / or contrast.

[0041] In other words, the color saturation and / or contrast of the first displayed content image can be adjusted, and the color saturation and / or contrast of the second displayed content image can also be adjusted, so that the adjusted first and second displayed content images can be simultaneously displayed in the display area with a preset transparency of ghosting. That is, the display area displays the first and second displayed content images simultaneously, and the display effect is a preset transparency of ghosting. In this way, even if new content is refreshed in the display area, the new content and the content displayed at the moment before the refresh can be displayed simultaneously with a preset transparency of ghosting, which is convenient for the driver to view and can provide the driver with the best image visual effect.

[0042] It is worth noting that content has different importance levels, so during display, the corresponding content can be displayed in a main display and background display manner according to the different importance levels. Optionally, in one embodiment of this application, the content importance levels corresponding to the first display content image and the second display content image can be determined respectively, and the main display image and the background image can be determined from the first display content image and the second display content image according to the content importance levels, and the main display image and the background image can be controlled to be displayed in the display area in a ghosting manner with a preset transparency.

[0043] In embodiments of this application, the display content image with a higher content importance level between the first display content image and the second display content image can be determined as the main display image, and the display content image with a lower content importance level between the first display content image and the second display content image can be determined as the background image.

[0044] For example, suppose the projection module in the vehicle head-up display has three display areas: area A, area B, and area C. For instance, area B needs to display navigation intersection 'a' and navigation instructions in the same location. Then, the first display content image can be determined to be the image corresponding to navigation intersection 'a', and the second display content image can be the image corresponding to the navigation instructions. It can be understood that, generally speaking, the navigation instructions at a navigation intersection are usually more important than the navigation intersection itself. That is, at a certain navigation intersection, the driver is more likely to know which direction to turn at the intersection. Therefore, the navigation intersection can be set as the background image, and the navigation instructions can be set as the main display image. At this time, the navigation intersection image and the navigation instruction image can be controlled to be displayed in the display area in a ghosting manner with preset transparency.

[0045] As an example, the display parameters of the main display image and the background image can be adjusted separately to display them in the display area in a ghosting manner with a preset transparency. For example, the contrast of the main display image can be adjusted to a first preset threshold, and the contrast of the background image can be adjusted to a second preset threshold, where the first preset threshold is greater than the second preset threshold. Alternatively, the saturation of the main display image can be adjusted to a third preset threshold, and the saturation of the background image can be adjusted to a fourth preset threshold, where the third preset threshold is greater than the fourth preset threshold. This allows the main display image and the background image to be displayed simultaneously in the display area in a ghosting manner with a preset transparency. For instance, if the display area of ​​a vehicle head-up display device needs to display both a navigation intersection and navigation instructions in the same location, then one may be used as a background and the other as the main display. If the navigation intersection is set as the background, its contrast should be low; then the navigation instructions should be set as the main display, its contrast should be high, and its RGB color saturation should be high. In the embodiments of this application, the contrast is adjusted by adjusting the Gamma curve.

[0046] It should be noted that, in one embodiment of this application, the display parameters of the main display image and the background image are adjusted respectively, so that the main display image and the background image are displayed in the display area in a ghosting manner with preset transparency, which can be achieved through a gradual transition. For example, as... Figures 3.1-3.6 The diagram shows the gradual transition between the main display image and the background image in the display area of ​​the vehicle head-up display device. The main display image can be understood as an image with turn indicators, and the background image can be understood as an image of a navigation intersection.

[0047] In embodiments of this application, a ghosting effect with preset transparency can be achieved by adjusting the saturation and contrast of the main display image and the background image. For example, as Figures 4.1-4.4 As shown, the desired result can be achieved by adjusting the RGB values ​​and contrast in the image. Figures 4.1-4.4 The four effects shown. Among them, as... Figure 4.1 As shown, the display area contains opaque blue text on a solid background. This can be achieved as follows: Maximize the RGB color saturation (B = 255) to make the background opaque. Set the RGB values ​​for the text to R = 255, G = 251, and B = 240 to create white text areas. Figure 4.2 As shown, the background of the displayed area is transparent, containing only solid text, and the RGB values ​​of the background area are consistent with the background. Figure 1 Thus, simply adjust the RGB values ​​of the physical characters, such as R=255, G=251, B=240, to achieve the white text area. Figure 4.3As shown, the display area features a transparent blue background with solid text. This can be achieved as follows: Adjust the RGB color saturation to B=30 to achieve a transparent background area with low contrast. Set the RGB values ​​for the font to R=255, G=251, and B=240 to create a white text area. Figure 4.4 As shown, the displayed area has a transparent background and indistinct text, achieving full transparency. This can be achieved as follows: Adjust the RGB color saturation to B=30 to achieve a transparent background area with low contrast. Set the RGB values ​​for the text to R=100, G=95, and B=80, also with low contrast. The above explains the color scheme principle for the four images. The Gamma curve is the parameter used to adjust contrast; adjusting contrast is equivalent to adjusting the Gamma curve. To achieve overlapping display, the four images are split into different time-shifting images, enabling animation and overlapping display. Important information can be displayed in this time-shifting manner to showcase the overlapping effect. For example, in navigation, an intersection might appear with overlapping directional arrows, or a car logo might be displayed alongside weather or other important information.

[0048] It should be noted that, in one embodiment of this application, when no content refresh is detected in the display area, the display parameters of the display area may not be adjusted, that is, the display area is controlled to display data in the original display mode.

[0049] According to the display control method of the vehicle head-up display device according to the embodiments of this application, it can detect whether the display area needs to be refreshed. The display area is an area used to achieve multiple displays of the same content. When it is detected that the display area needs to be refreshed, the method determines the first display content image displayed before the content refresh, determines the second display content image to be displayed when the content refresh occurs, and controls the first and second display content images to be displayed in the display area with a preset transparency ghosting effect. That is, when multiple displays of certain content are needed in the display area, these contents can be displayed in the display area with a preset transparency ghosting effect. Thus, this application can project the best image visual effect in any scenario. By receiving data content and instructions through the HUD, it can achieve control over the semi-transparent display of images and the refresh of display area content, enriching the projection content and display effect of the HUD projection display area, and improving the user experience.

[0050] Corresponding to the display control methods of the vehicle head-up display device provided in the above embodiments, an embodiment of this application also provides a display control device for the vehicle head-up display device. Since the display control device for the vehicle head-up display device provided in this embodiment corresponds to the display control methods of the vehicle head-up display device provided in the above embodiments, the implementation methods of the aforementioned display control methods for the vehicle head-up display device are also applicable to the display control device for the vehicle head-up display device provided in this embodiment, and will not be described in detail in this embodiment. Figure 5 This is a schematic diagram of the structure of the display control device of a vehicle head-up display according to an embodiment of this application. Figure 5 As shown, the display control device 500 of the vehicle head-up display device may include: a content refresh detection module 510, a first determination module 520, a second determination module 530, and a display control module 540.

[0051] Specifically, the content refresh detection module 510 is used to detect whether the display area needs to be refreshed, wherein the display area is the area used to realize multiple displays of the same content.

[0052] The first determining module 520 is used to determine the first display content image displayed in the display area before the content refresh is performed when it is detected that the display area needs to be refreshed.

[0053] The second determining module 530 is used to determine the second display content image to be displayed when the display area is refreshed.

[0054] The display control module 540 is used to control the first display content image and the second display content image to be displayed in the display area in a ghosting manner with preset transparency.

[0055] It is worth noting that content has different levels of importance, so when displaying content, the corresponding content can be displayed as a main display or background display according to its importance level. Optionally, in one embodiment of this application, such as Figure 6 As shown, the display control module 540 may include: a content importance level determination unit 541, an image determination unit 542, and a display control unit 543. The content importance level determination unit 541 is used to determine the content importance levels corresponding to the first display content image and the second display content image, respectively; the image determination unit 542 is used to determine the main display image and the background image from the first display content image and the second display content image based on the content importance levels; and the display control unit 543 is used to control the main display image and the background image to be displayed in the display area with a preset transparency of ghosting.

[0056] In the embodiments of this application, the image determination unit 542 is specifically used to: determine the display content image with a higher content importance level among the first display content image and the second display content image as the main display image; and determine the display content image with a lower content importance level among the first display content image and the second display content image as the background image.

[0057] In embodiments of this application, the display control unit 543 is specifically configured to: adjust the display parameters of the main display image and the background image respectively, so that the main display image and the background image are displayed in the display area in a ghosting manner with preset transparency. The display parameters may include, but are not limited to, saturation and / or contrast.

[0058] According to the vehicle head-up display device of this application embodiment, the display control device can detect whether the display area needs to be refreshed through a content refresh detection module. The display area is an area used to achieve multiple displays of the same content. When the content refresh detection module detects that the display area needs to be refreshed, the first determining module determines the first display content image displayed before the content refresh. The second determining module determines the second display content image to be displayed when the display area is refreshed. The display control module controls the first and second display content images to be displayed in the display area with a preset transparency and a ghosting effect. That is, when multiple displays of certain content are needed in the display area, these contents can be displayed in the display area with a preset transparency and a ghosting effect. Thus, this application can project the best image visual effect in any scenario. By receiving data content and instructions through the HUD, it can achieve control over the semi-transparent display of images and the refresh of the display area content, enriching the projection content and display effect of the HUD projection display area and improving the user experience.
