[0026] The following will be combined with the drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application belong to the scope of protection of this application.

It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0028] The vehicle-mounted ambient light control method provided by the embodiment of the present application is described in detail below through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0029] Figure 1 FIG. 1 is a flow chart of a method for controlling a vehicle ambient light according to an exemplary embodiment, comprising the following steps:

[0030] Step S11: Acquire the display image of the central control display screen and extract the color information of the display image.

[0031] In the related technologies, the vehicle ambient light control method usually relies on fixed preset scenes or simple audio spectrum analysis to control the lighting effects, and lacks the ability to dynamically respond to visual information, resulting in the lighting effects being unable to reflect changes in visual information in real time and poor interactivity, thereby reducing the user's sense of immersion and overall experience.

[0032] Based on this, the present application proposes a method for controlling vehicle ambient lights, which dynamically adjusts the vehicle ambient lights in real time by extracting and clustering information based on the image displayed on the central control display screen to solve the above problems.

[0033] In this step, the display image of the central control display screen needs to be obtained first, wherein the display image of the central control display screen is the screen content currently displayed by the central control display screen, which changes in real time with the change of the content displayed by the central control display screen. For example, when the user is watching a video, the display image is the video screen being played, and when the user is playing a game, the display image is the real-time game screen, and so on.

[0034] After acquiring the display image, the color information of the display image can be extracted for use in adjusting the color of the vehicle ambient light. The color information can be represented by different color spaces, such as RGB (red, green, and blue) color space, HSV (hue, saturation, and brightness) color space, CMYK (cyan, magenta, yellow, and black) color space, etc., without limitation.

[0035] In an embodiment of the present application, in order to reduce computational complexity and speed up processing, before performing cluster analysis on color information, the display image can be preprocessed first, including but not limited to scaling the display image to reduce the volume of image data, so that subsequent processing steps can be completed faster while maintaining the integrity of the color information as much as possible.

[0036] Step S12: Divide the color range into a preset number according to the color information.

[0037] In this step, the color information can first be divided into a preset number of different color ranges. The division of each color range can be defined based on the color space corresponding to the color information, depending on the needs of color analysis. The preset number is usually determined based on the accuracy requirements of image analysis. The higher the preset number, the higher the accuracy, but it may cause the colors to be too dispersed and difficult to determine the main color tone; the lower the preset number, the more important color information may be lost, which can be determined based on the application scenario and needs.

[0038] In one implementation, the color information includes the color value of each pixel corresponding to multiple color channels, and a preset number of color ranges are divided according to the color information, including:

[0039] According to the color information, a color histogram is constructed; the color histogram includes multiple dimensions, and each dimension corresponds to each color channel;

[0040] For the color histogram of each dimension, calculate the difference between the maximum and minimum values ​​of the included color values ​​as the corresponding color range;

[0041] Determine the largest color range as the target range;

[0042] Calculate the median value of the color values ​​in the target range, and divide the target range into two new color ranges according to the median value;

[0043] Return to the step of determining the largest color range as the target range until the number of obtained color ranges reaches the preset number.

[0044] That is to say, in this embodiment, the median cut algorithm can be used to implement cluster analysis of color information and extract the main color tone in the display image. The median cut algorithm is an algorithm commonly used for cluster analysis of color information. By recursively dividing the color information, the color information is clustered into a limited number of color ranges, and the main color tone of the display image is then identified.

[0045] Specifically, the implementation process of the median cut algorithm includes the following steps:

[0046] First, the color information of all pixels in the displayed image is statistically displayed to construct a color histogram. The horizontal axis of the color histogram represents the color value, and the vertical axis represents the number of pixels of a certain color value. The color information includes the color values ​​of each pixel corresponding to multiple color channels. Correspondingly, the color histogram includes multiple dimensions, each of which corresponds to each color channel. For example, if the color information corresponds to the three color channels of red (R), green (G) and blue (B), then the color histogram is a three-dimensional color histogram corresponding to the three color channels.

[0047] Then, the color range of each color channel is calculated, that is, the difference between the maximum and minimum color values ​​in the color histogram of each dimension. Continuing the above example, if the color information corresponds to the three color channels of red, green and blue, then the color range of each color channel can be expressed as:

[0048] R range =R max -R min

[0049] G range =G max -G min

[0050] B range =B max -B min

[0051] Among them, R max ,R min are the maximum and minimum values ​​of the red channel, G max ,G min are the maximum and minimum values ​​of the green channel, B max ,B min are the maximum and minimum values ​​of the blue channel, R range ,G range ,B range They represent the color range of the three color channels: red, green, and blue.

[0052] Afterwards, the largest color range is determined as the target range, the median value of the color values ​​of the target range is calculated, and the target range is divided into two new color ranges according to the median value, thereby realizing the cutting of the color range.

[0053] For example, if R range >G range And R range >B range , then cut the color range corresponding to the red channel; if G range >B range And G range >R range , then cut the color range corresponding to the green channel; if B range >G range And B range >R range , the color range corresponding to the blue channel is cut.

[0054] After determining the target range, calculate the median value of the target range, expressed as:

[0055]

[0056] Among them, C median is the median value, C max and C min are the maximum and minimum values ​​of the target channel respectively.

[0057] The target range is divided into two by calculating the median value of the target range, and recursively returns to determine the largest color range as a step of the target range until a preset number of color regions are obtained.

[0058] Step S13: Count the number of pixels included in each color range, and determine the color range with the largest number of pixels as the main color.

[0059] In this step, we first need to count the number of pixels included in each color range. It can be understood that the number of pixels included in each color range in an image usually reflects the relative importance or proportion of the color range in the image. Therefore, the color range with the largest number of pixels is determined as the main color tone, so that the main color tone reflects the most prominent or dominant color in the displayed image.

[0060] In this way, by clustering the color information of the image displayed on the central control display screen, the color tone that occupies the main position in the displayed image can be identified as the main color tone corresponding to the displayed image, which is conducive to better understanding the content and characteristics of the displayed image. For example, if the main body of the displayed image is a landscape, the main colors may be green and blue, and if the main body of the displayed image is a sunset, the main colors may be orange and red.

[0061] Furthermore, in subsequent steps, by controlling the light color of the vehicle ambient light based on the main color tone, the color scheme of the vehicle ambient light can be more matched with the display image of the central control display screen, achieving visual harmony and unity.

[0062] In one implementation, after counting the number of pixels included in each color range and determining the color range with the largest number of pixels as the main color, the following further includes:

[0063] For other color ranges except the main hue, if the number of pixels included in any other color range meets a preset condition, any other color range is determined as a vibrant hue.

[0064] That is to say, in the present application, in addition to determining the main color tone of the displayed image, one or more additional vibrant tones can also be determined. In subsequent steps, the light color of the vehicle-mounted ambient light can be controlled to display the color values ​​corresponding to the main color tone and the vibrant tones, so as to further enhance the visual effect of the ambient light.

[0065] Among them, the preset condition may mean that the proportion of pixels of vibrant hues is significantly higher than that of other color ranges, for example, the ratio of the number of pixels of vibrant hues to the number of pixels of the main hue exceeds 70%, or the number of pixels of vibrant hues exceeds a certain ratio of the total number of pixels of the displayed image, etc., without specific limitation.

[0066] In one implementation, dividing a preset number of color ranges according to color information includes:

[0067] Dividing the displayed image into a plurality of regions;

[0068] According to the color information in each area, each area is divided into a preset number of color ranges;

[0069] Count the number of pixels in each color range, and determine the color range with the largest number of pixels as the main color, including:

[0070] For each region, the number of pixels included in each corresponding color range is counted, and the color range with the largest number of pixels is determined as the main color tone of the region.

[0071] Specifically, in order to further enhance the user's sense of immersion, the displayed image can also be segmented into multiple regions, and each region can be divided into a preset number of color ranges based on the color information in each region. Then, for each region, the number of pixels included in each color range corresponding to the region is counted, and the color range with the largest number of pixels is determined as the main color of the region, thereby realizing cluster analysis of the color information of each region and extracting the main color of each region. The main colors of these different regions will be respectively applied to the light colors of different vehicle-mounted atmosphere lights, making the lighting effects richer and more delicate, especially in specific situations such as complex pictures or multi-scene switching, which will be more useful.

[0072] Step S14: Control the light color of the vehicle ambient light to display the color value corresponding to the main color tone.

[0073] In this step, after determining the main color tone, the main color tone can be sent to the controller of the vehicle ambient light, and the controller adjusts the light color of the vehicle ambient light according to the received main color tone, and controls the light color of the vehicle ambient light to display the color value corresponding to the main color tone. Since the processing of the displayed image is performed in real time, the light color of the vehicle ambient light is also updated in real time to match the main color tone of the current displayed image.

[0074] If the vehicle ambient light uses a color space or format different from the main color, the color value may need to be converted. For example, if the image processing obtains RGB values, and the vehicle ambient light uses hexadecimal color codes or a specific color representation method, a corresponding conversion is required.

[0075] In one implementation, when the main color tone is RGB color information, controlling the light color of the vehicle ambient light to display the color value corresponding to the main color tone includes:

[0076] Convert the main color tone into HSB color information to obtain first information; the first information includes a first brightness;

[0077] The value of the first brightness is adjusted to a second brightness to obtain second information; the second brightness is higher than the first brightness;

[0078] Convert the second information into RGB color information to obtain a color value corresponding to the main color tone;

[0079] The light color of the vehicle ambient light is controlled and displayed as a color value.

[0080] That is to say, when the main color tone is RGB color information, the main color tone needs to be converted into HSB color information first to obtain first information, wherein the first information includes a first brightness; then, the first brightness needs to be adjusted to obtain second information, and the second information is converted back to RGB color information to generate a final color value, thereby improving the display brightness of the light color.

[0081] For example, the formula for adjusting the value of the first brightness to the second brightness can be expressed as:

[0082] Badjusted=min(1.0,2×B)

[0083] Among them, B represents the first brightness, B adjusted Indicates the second brightness, and min indicates the minimum value.

[0084] This brightness adjustment method not only ensures the visual effect of color, but also avoids the inconsistency of the ambient light effect in different brightness environments, so that the vehicle ambient light always remains within an optimal brightness range, avoiding the main color tone being too dim when applied to the vehicle ambient light.

[0085] In one implementation, if the vitality tone is determined after the main tone is determined, then the light color of the vehicle ambient light is controlled to be displayed as the color value corresponding to the main tone, including:

[0086] The light color of the vehicle's ambient light is controlled to display the color values ​​corresponding to the main color and the vibrant color.

[0087] That is to say, the main tone and the vibrant tone can be used together for the light color of the vehicle atmosphere light to make the lighting effect richer and more delicate. For example, the vehicle atmosphere light can be divided into two parts according to a certain proportion, one part showing the color value corresponding to the main tone, and the other part showing the color value corresponding to the vibrant tone; or, according to the different positions of the vehicle atmosphere light, it can be set to correspond to the color value corresponding to the main tone or the color value corresponding to the vibrant tone, and so on, without specific limitation.

[0088] In one implementation, the vehicle ambient light control method further includes:

[0089] Acquire the audio signal in the car and convert the audio signal into a frequency domain signal;

[0090] Determine the lighting parameters of the vehicle ambient light based on the frequency domain signal;

[0091] Then, the color of the light that controls the vehicle's ambient light is displayed as the color value corresponding to the main color tone, including:

[0092] Based on the lighting parameters, the lighting color of the vehicle ambient light is controlled to display the color value corresponding to the main color tone.

[0093] That is to say, before controlling the vehicle ambient light, you can first obtain the audio signal in the car, then convert the audio signal into a frequency domain signal, and by analyzing the frequency changes of the vehicle audio signal, you can determine the lighting parameters of the vehicle ambient light based on the frequency domain signal.

[0094] In this way, the lighting parameters of the car's ambient light can be adjusted dynamically in real time in combination with the frequency changes of the audio signal in the car, so that the car's ambient light can synchronize with the rhythm of the audio signal in real time and change accordingly to enhance the user's immersive experience.

[0095] Among them, the fast Fourier transform can be used to obtain the energy distribution of the audio signal at each frequency, and the audio signal can be converted from the time domain to the frequency domain in order to analyze its frequency components. The calculation formula of the fast Fourier transform is as follows:

[0096]

[0097] Among them, X(k) is the frequency domain signal, x(n) is the time domain signal, N is the signal length, k is the frequency index, and j is the imaginary unit.

[0098] In one implementation, determining the lighting parameters of the vehicle ambient light according to the frequency domain signal includes:

[0099] Calculate the total energy value in each frequency band according to the frequency domain signals corresponding to the preset multiple frequency bands;

[0100] For each frequency band, the lighting parameters corresponding to the total energy value are determined based on a predefined mapping relationship.

[0101] That is to say, multiple frequency bands may be divided in advance according to the frequency, and then the total energy value in each frequency band may be calculated according to the frequency domain signal corresponding to each frequency band.

[0102] The calculation formula of the total energy value can be expressed as:

[0103]

[0104] Among them, E band It represents the total energy value of a frequency band, and |X(k)| is the amplitude of the frequency domain signal of this frequency band.

[0105] By calculating the total energy value of each frequency band, the energy distribution of the audio signal in each frequency band can be identified. Then, the lighting parameters corresponding to the total energy value can be further determined based on a predefined mapping relationship.

[0106] In one implementation, for each frequency band, based on a predefined mapping relationship, determining the lighting parameter corresponding to the total energy value includes:

[0107] For the frequency band within the preset low-frequency range, based on the predefined nonlinear mapping relationship, the light intensity corresponding to the total energy value is determined as the light parameter; the light intensity is positively correlated with the total energy value.

[0108] It can be understood that the frequency band of the frequency domain signal can be divided into several ranges such as low frequency (20Hz-250Hz), medium frequency (250Hz-4kHz) and high frequency (4kHz-20kHz). Among them, when the total energy of the low frequency band is high, it means that the audio signal has a strong bass effect, and when the total energy of the medium frequency band and the high frequency band is high, it means that the mid-range and treble effects of the audio signal are prominent. Based on this, the mapping relationship between different frequency bands and lighting parameters can be pre-defined.

[0109] In this embodiment, for the frequency band within the preset low-frequency range, the light intensity corresponding to the total energy value is determined based on a predefined nonlinear mapping relationship, thereby achieving an effect of increasing the light intensity of the vehicle ambient light when the total energy of the low-frequency band is higher.

[0110] For example, the predefined nonlinear mapping relationship can be expressed as:

[0111] I band =a·log(E band )+b

[0112] Among them, I band is the light intensity, E band is the total energy value of the frequency band, and a and b represent different adjustment parameters.

[0113] In one implementation, for each frequency band, based on a predefined mapping relationship, determining the lighting parameter corresponding to the total energy value includes:

[0114] For the frequency band within the preset high frequency range, based on the predefined linear mapping relationship, the flickering frequency corresponding to the total energy value is determined as the lighting parameter; the flickering frequency is positively correlated with the total energy value.

[0115] In this embodiment, for the frequency band within the preset high-frequency range, the flashing frequency corresponding to the total energy value is determined based on a predefined linear mapping relationship, thereby achieving the effect of increasing the flashing frequency of the vehicle ambient light when the total energy of the high-frequency band is high.

[0116] For example, the predefined linear mapping relationship can be expressed as:

[0117] F band =c·E band +d

[0118] Among them, F band is the flashing frequency, E band is the total energy value of the frequency band, and c and d represent different adjustment parameters.

[0119] In this way, an accurate response to the rhythm of the audio signal can be achieved, so that the vehicle ambient light has a higher intensity at low frequencies and a lower intensity at high frequencies, thereby producing a visual effect that matches the rhythm of the music.

[0120] From the above, it can be seen that the technical solution provided by the embodiment of the present application determines a certain main color tone by extracting color information and clustering analysis of the display image of the central control display screen, and then controls the light color of the vehicle atmosphere light to display the color value corresponding to the main color tone, thereby realizing real-time and dynamic adjustment of the light color of the vehicle atmosphere light in combination with the display image of the central control display screen. It has strong interactivity and does not need to rely on complex hardware during the implementation process, thus avoiding cumbersome hardware adjustments. It shows high adaptability and high stability in a variety of driving environments.

[0121] The vehicle atmosphere light control method provided in the embodiment of the present application can be executed by a vehicle atmosphere light control device. In the embodiment of the present application, the vehicle atmosphere light control device performs a terminal access method as an example to illustrate the vehicle atmosphere light control method provided in the embodiment of the present application.
