[0002] The multi-screen trend in vehicle cockpits is an inevitable development direction. Instrument screens, central control screens, co-pilot screens, rear-seat entertainment screens, etc. have almost become standard configurations, and there are also emerging ones such as head-up displays, electronic rearview mirror screens, and blind-spot prevention screens.

[0024] The exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments set forth herein.

[0025] Figure 1 It shows a flowchart of the first embodiment of the screen display effect adjustment method of the present invention, and this method can be executed by a Destination Surface Processor (DSPP).

[0026] As the core component of the display processing layer, the core function of the destination surface processor is to dynamically convert and correct image data through the panel characteristic adaptation algorithm to ensure that the final display effect is accurately matched with the hardware characteristics. The destination surface processor and the display panel (screen) can be independent hardware entities in the vehicle entertainment system, but they form a tightly coupled relationship through physical interfaces, signal protocols, and functional coordination. Among them, the destination surface processor can be integrated in the cockpit domain controller.

[0027] The Multimedia Display Sub-System (MDSS) is a complex display processing system designed by chip manufacturers for mobile devices. It is responsible for processing all image and video data from applications to the display screen, including components such as the Source Surface Processor (SSPP), Layer Mixer (LM), Write-Back (WB) module, and Destination Surface Processor. That is to say, the Destination Surface Processor is a key component in the multimedia display sub-system. The functions of each component are explained as follows:

[0028] Source Surface Processor: It consists of a VIG (pipe–For video and graphics) video image pipeline, an RGB (Red, Green, Blue) image pipeline, and a DMA (Direct Memory Access) image and rotation pipeline. The Source Surface Processor can read source image data in RGB and YUV formats from game and video applications and is responsible for format conversion and quality optimization of the source image data. The image data output by the Source Surface Processor enters the Layer Mixer.

[0029] Layer Mixer: It realizes the mixing and overlay of multiple layers (such as the navigation interface, video layer, UI controls) and supports property control such as transparency and layer level. For example, the Layer Mixer needs to process dashboard information, navigation maps, and multimedia content to ensure conflict-free overlay of each layer. The Layer Mixer receives the image data output by the Source Surface Processor, completes the mixing through a hardware acceleration algorithm, and outputs it to the Destination Surface Processor for final correction.

[0030] Write-Back Module: It supports the write-back operation of image data and can realize dynamic rotation or storage of the screen content. For example, in the scenario of switching between portrait and landscape screens, the WB rewrites the processed image data back into memory for the system or other modules to call. The Write-Back Module, as an optional module, cooperates with the Destination Surface Processor to complete the closed-loop management of the display data.

[0031] Destination Surface Processor: It converts, corrects, and adjusts the image according to the display panel characteristics (such as resolution, color space, refresh rate). As the final processing node, the Destination Surface Processor receives the image data mixed by the Layer Mixer, combines the panel parameters to generate a display signal that meets the hardware requirements, and ensures the accurate restoration of the composite image on the screen.

[0032] The screen display effect adjustment method of the present invention can be executed by the Destination Surface Processor in the above multimedia display sub-system, as Figure 1 shown, and the method includes the following steps:

[0033] Step 110: When color parameter adjustment information is obtained from the device file node of any screen, an image display signal is generated based on the composite image obtained from the layer mixer, in combination with the panel characteristics of the screen and the color parameter adjustment information. The color parameter adjustment information is generated in response to the user's color adjustment operation on the upper computer and stored in the device file node corresponding to the screen. The screen in the vehicle cockpit is provided with a corresponding device file node, and the device file node exists as an access interface for the corresponding screen.

[0034] Among them, the device file node provides a unified interface for the device driver, enabling the application program to interact with the device through standard file operations (such as opening, closing, reading, writing, etc.). This design simplifies the access of the application program to the device. In the vehicle cockpit environment, using the QNX device file node, multiple screens can be effectively managed and controlled.

[0035] In the embodiment of the present invention, each screen has a corresponding device file node. Various information related to the screen is stored in the device file node corresponding to each screen. The color parameter adjustment information can be obtained from the device file node of the screen, and the color parameter adjustment information is generated after the user's color adjustment operation on the upper computer. These information are stored in the device file node corresponding to the screen.

[0036] The target surface processor can generate an image display signal based on the composite image obtained from the layer mixer, in combination with the panel characteristics of the screen and the obtained color parameter adjustment information.

[0037] Step 120: Send the image display signal to the screen to adjust the display effect of the composite image on the screen.

[0038] By sending the image display signal, the display effect of the composite image on the screen is adjusted to achieve the expected color performance. The user's color adjustment operation can be quickly reflected on the screen display, realizing instant feedback.

[0039] For the screen display effect adjustment method provided by the embodiment of the present invention, the user can uniformly adjust the colors of multiple screens through the upper computer. This centralized control method simplifies the operation process, making color management more efficient and convenient. R & D personnel can adjust the color parameters of multiple screens simultaneously, avoiding the cumbersome process of adjusting each screen one by one. The color parameter adjustment information will be stored in the device file node corresponding to the screen. By accessing the device file node, batch adjustment of color parameters can be quickly performed to ensure that the color display of each screen is consistent with that of other screens. The embodiment of the present invention provides an efficient way to manage and adjust the color display of multiple screens in the vehicle cockpit, and can solve the problem of inconsistent colors between screens of different manufacturers in the vehicle cockpit.

[0040] Figure 2 The flowchart of another embodiment of the method for adjusting the screen display effect of the present invention is shown, and this method is executed by the target surface processor. As Figure 2 shown, the method includes the following steps:

[0041] Step 210: When color parameter adjustment information is obtained from the device file node of any screen, perform color correction, color calibration, and color optimization on the composite image based on the panel characteristics of this screen and the color parameter adjustment information to generate an image display signal. The color parameter adjustment information is generated in response to the user's color adjustment operation on the upper computer and stored in the device file node corresponding to this screen. The screen in the vehicle cockpit is provided with a corresponding device file node, and the device file node exists as an access interface for the corresponding screen.

[0042] In an optional manner, the screen includes one or more of an instrument screen, a central control screen, a co-pilot screen, a rear row entertainment screen, a head-up display, an electronic rearview mirror screen, and a blind spot prevention screen.

[0043] In an optional manner, the color adjustment operation includes one or more of a hue adjustment operation, a saturation adjustment operation, a brightness adjustment operation, and a contrast adjustment operation.

[0044] The user can perform color adjustment operations on the upper computer, and the user can adjust parameters such as hue, saturation, brightness, and contrast. The upper computer sends these adjustment parameters to the vehicle-mounted system through serial communication. The vehicle-mounted system stores the received color parameter adjustment information in the device file node corresponding to the screen.

[0045] Referring to Figure 3 shown, it is a schematic diagram of the color adjustment user interface provided by the present invention, which includes four color adjustment options: hue, saturation, brightness, and contrast. There is a slider beside each color adjustment option, and the user can adjust the corresponding color parameters by moving the pointer on the slider. In addition, multiple serial port options and multiple screen options are provided. The user can select one of the multiple serial ports for connection, and the user can select the screen whose color needs to be adjusted from multiple screens. Further, the user can be allowed to set the step value of the color parameter adjustment, which means that the user can fine-tune the color parameters in smaller or larger steps, so as to achieve more precise control. The user can also be allowed to save the set color parameters, so that after the software is closed or restarted, the user can also restore to the previous settings to prevent data loss.

[0046] Based on the color parameter adjustment information read from the device file node and combined with the panel characteristics of the screen, color correction, color calibration, and color optimization are performed on the composite image. Color correction refers to adjusting the colors of the image to correct any color deviations caused by device characteristics or input signals. By reading the color parameter adjustment information stored in the device file node, the color parameters that need to be corrected (such as hue, saturation, intensity, contrast) can be identified, and preliminary color correction can be performed on the image to ensure color accuracy. Color calibration is to ensure that the colors displayed on the screen are consistent with the expected standard colors, which requires considering the specific panel characteristics of the screen. By using calibration algorithms, the color output of the image can be adjusted to conform to specific color standards. Color optimization is to enhance the visual effect of the image to make it more attractive under specific environments (such as the lighting conditions in a vehicle cockpit). The combination of these processing steps ensures better color performance of the image display signal on the screen, meeting the user's demand for a high-quality visual experience.

[0047] In an alternative manner, when obtaining the color parameter adjustment information from the device file node of any screen, before generating the image display signal based on the composite image obtained from the layer mixer and combining the panel characteristics of the screen and the color parameter adjustment information, the screen display effect adjustment method according to the embodiments of the present invention may specifically further include the following steps:

[0048] Create an independent thread;

[0049] Based on the created independent thread, read the content in the device file nodes of different screens after a preset interval to determine whether new color parameter adjustment information has been stored within the preset interval.

[0050] In this embodiment, an independent thread can be created in the destination surface processor specifically for monitoring the color parameter adjustment information in the device file node. This multi-threaded design can ensure that the main thread's image processing and display tasks are not interfered with by the monitoring task, thereby improving the overall performance of the system. Based on the created independent thread, reading the content in the device file nodes of different screens after a preset interval, this timing reading mechanism can effectively monitor whether new color parameter adjustment information has been stored. Through the independent thread and the timing reading mechanism, changes in color parameters can be quickly detected and the display effect can be updated in a timely manner.

[0051] In an alternative manner, performing color correction, color calibration, and color optimization on the composite image based on the panel characteristics of the screen and the color parameter adjustment information to generate the image display signal may specifically include the following steps:

[0052] Judge whether the color parameters in the color parameter adjustment information are within the preset adjustment range,

[0053] If it is within the preset adjustment range, adjust the color processing pipeline;

[0054] Use the adjusted color processing pipeline to perform color correction on the composite image;

[0055] Based on the panel characteristics of the screen, perform color calibration on the color-corrected composite image;

[0056] Perform color optimization on the color-calibrated composite image to generate an image display signal.

[0057] In this embodiment, first check the color parameter adjustment information obtained from the device file node, and determine whether these parameters are within the preset adjustment range. The preset adjustment range is set according to the screen characteristics and user experience requirements to ensure that the adjusted image does not exceed a reasonable visual effect.

[0058] If the color parameters are within the preset range, adjust the color processing pipeline, use the adjusted color processing pipeline to perform color correction on the composite image, based on the panel characteristics of the screen, perform color calibration on the color-corrected composite image, perform color optimization on the color-calibrated composite image, and generate the final image display signal.

[0059] Step 220: Send the image display signal to the screen to adjust the display effect of the composite image on the screen.

[0060] In an alternative manner, sending the image display signal to the screen may specifically include the following steps:

[0061] Input the image display signal into a pre-packaged mobile display processor interface function and send it to the screen.

[0062] The MDP (Mobile Display Processor) interface function is the core bridge connecting the multimedia display subsystem and the display hardware, and is responsible for converting abstract image data into electrical signals that meet the requirements of the physical panel drive.

[0063] Refer to Figure 4As shown in the figure, it is the system architecture flowchart of the screen display effect adjustment method provided by the present invention, including the Multimedia Display Subsystem (MDSS) bus interface, shared memory pool, VIG video image pipeline, RGB image pipeline 0 and RGB image pipeline 1, DMA image pipeline, cross switch, layer mixers LM1 and LM3, and write-back modules WB0 and WB2. The user performs color adjustment operations on the screen in the host computer to generate color parameter adjustment information. The host computer sends the color parameter adjustment information to the device file node of the vehicle system for storage through serial communication. The destination surface processor (DSPP) can identify different screens based on the screen ID. The DSPP polls the content in the device file node every 10 ms. When color parameter adjustment information is obtained from the device file node of any screen, it performs color correction, color calibration, and color optimization on the composite image obtained from the layer mixer based on the panel characteristics of the screen and the color parameter adjustment information to generate an image display signal, and can input the image display signal into the pre-packaged Mobile Display Processor (MPD) interface function and send it to the screen. The destination surface processor can identify different screens and adjust their color parameters separately to achieve the unification of multi-screen colors. This method realizes color adjustment without changing the screen firmware.

[0064] In the screen display effect adjustment method provided by the embodiments of the present invention, the user can perform unified color adjustment on multiple screens through the host computer. This centralized control method simplifies the operation process and makes color management more efficient and convenient. R & D personnel can adjust the color parameters of multiple screens at the same time, avoiding the cumbersome process of adjusting each screen one by one. The color parameter adjustment information will be stored in the device file node corresponding to the screen. By accessing the device file node, batch adjustment of color parameters can be quickly performed to ensure that the color display of each screen is consistent with that of other screens. The embodiments of the present invention provide an efficient way to manage and adjust the color display of multiple screens in a vehicle cockpit, and can solve the problem of inconsistent colors between screens of different manufacturers in the vehicle cockpit.
