detailed description

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

Embodiment one

Referring to FIG. 1 , it is a schematic flowchart of an ambient light control method provided by an embodiment of the present invention, and the method includes steps S1 to S3;

S1, in response to the start instruction of the in-vehicle game input by the user, sequentially intercept the screen image of the current screen of the central control screen of the car terminal according to the preset screen capture interval time;

S2, extracting a preset number of main colors in the intercepted picture image as color parameters;

S3. Control the ambient light configured at the car end to output light with a corresponding tone according to the tone parameter.

In the specific implementation of this embodiment, the ambient light configured on the car end will be jointly controlled with the car end, and the control process of the ambient light requires the user to start the car game;

After the user starts the in-vehicle game, the follow-up ambient light control process is carried out, and the screen image of the current screen of the car's central control screen is sequentially intercepted according to the preset screen capture interval time. The length of the screen capture interval can determine the tone parameters of the subsequent ambient light control. The amount of data also affects the computing power occupied by the control process. Therefore, it is necessary to set an appropriate screen capture time interval. In the scene of in-vehicle games, it can improve the game experience while reducing the large occupation of the computing power of the car.

Extract the preset number of main colors in the captured image as color parameters, and the number of main colors to be extracted also needs to be pre-designed to avoid the existing image processing algorithm automatically extracting an appropriate amount of main colors during the main color extraction process, which will cause the main color extraction to take up a lot of time. The large computing power also avoids the imbalance of ambient light control caused by the uneven number of extracted main colors.

According to the tone parameters, the ambient light configured on the car is controlled to output the corresponding tone light, so as to provide users with more rhythmic and immersive ambient light by extracting the main tone of the screenshot image of the game and controlling the atmosphere light according to the game tone. .

Embodiment two

In yet another embodiment provided by the present invention, the screenshot interval Q=X/(M*N);

Among them, X is the average playing time of each in-vehicle game opened according to the statistics of the operation data of the in-vehicle game recorded in the vehicle terminal, and M is the average playing time of each in-vehicle game opened according to the statistics of the operation data of the in-vehicle game recorded in the vehicle terminal. The number of levels to play, N, the average art style type of each game level calculated according to the running data of the vehicle game recorded in the vehicle terminal.

In the specific implementation of this embodiment, when the user starts the in-vehicle game and is running normally, the screen capture timing is determined by determining a reasonable screen capture interval time, so as to reduce the number of screen captures and subsequent main color recognition computing power occupation, specifically:

The car end counts the running data of the car game every time the car game is turned on and off, including the running time from the car game on to off, the number of levels played and the art style of the game level. The art style of the game level can be determined by the game settings, The game is analyzed and determined by a preset algorithm or entered manually.

According to the operating data recorded in the car terminal, the average playing time of each in-vehicle game is X seconds, the average number of levels played in each in-vehicle game is M, and the average art style of each game level is N.

Therefore, the number of screenshots is M*N, the total duration is X, and the interval screenshot time is set to Q=X/(M*N), that is, the screenshot is automatically completed every Q seconds. Among them, X, M, and N can be set as adjustable parameters. In the initial state, X, N, and X can all be set to an initial value based on experience, and during the running of the car game, as the running data is collected more and more More follow-up adjustments; set the initial value, X = 1800 seconds, M = 3, N = 5, and calculate the initial value Q = 120 seconds.

By counting the game running data and setting the screen capture interval, the ambient light control process can be determined according to the user's game data, and humanized ambient light control can be realized.

Embodiment three

In yet another embodiment provided by the present invention, the extraction of a preset number of dominant hues in the intercepted screen image as hue parameters specifically includes:

Using the main tone extraction algorithm to sequentially extract the color of the preset number of pixels in the picture image from high to low as the main tone;

Several colors in the main hue are sorted according to the number of pixels in the screen image from high to low as the hue parameter.

In the specific implementation of this embodiment, after the screen image is extracted, it is necessary to use an image processing algorithm to extract the main color, specifically:

Use current mature image processing algorithms, such as picture color quantization algorithms to calculate the number of pixels of different colors in the picture image;

Sort the colors according to the number of pixels, and determine the preset number of colors that are ranked first as the main color;

Several colors in the main hue are sorted according to the number of pixels in the screen image from high to low as the hue parameter.

Extract a preset number of main colors as color parameters through the main color extraction algorithm, and control the ambient light according to the extracted color parameters, so as to match the ambient light with the image color of the game screen and create an immersive atmosphere that matches the game screen.

Embodiment four

In yet another embodiment provided by the present invention, the preset number is not greater than the number of colors supported by the ambient light.

In the specific implementation of this embodiment, since the number of colors corresponding to the atmosphere lights installed in different cars is different, before performing the atmosphere lights, it is necessary to consider the number of colors supported by the atmosphere lights to define the number of main colors to be extracted.

For example, the number of colors supported by the multi-color ambient light currently installed on the car is X, and the preset number of extracted main colors is set to Y, then Y≤X must be satisfied to avoid the number of extracted main colors exceeding the colors supported by the current ambient light When the quantity is exceeded, the color tone of the ambient light will display abnormally.

In addition, when setting the number of main colors to be extracted, you can also refer to the screen type of the game screen. For example, the game screen basically includes game backgrounds, game characters, and game props; therefore, the preset number Y of main colors can be preset to 3, and Y is used as The reference configuration items can be adjusted dynamically; considering that Y≤X must be satisfied at the same time, if Y>X is set, the preset number of main colors needs to be reduced to equal to the number of colors supported by the ambient light.

By limiting the number of tones to be extracted, it is possible to avoid the problem that too many tones may not match the output of the ambient light, and it is also possible to avoid the large occupation of computing power caused by extracting too many main tones.

Embodiment five

When the color does not exist in the color library, randomly select a color in the color library, and use the color value corresponding to the color to control the ambient light to output light with a corresponding hue.

In the specific implementation of this embodiment, when controlling the ambient light with the hue parameters generated according to the identified main hue, it is necessary to consider whether the hue matches the color of the ambient light;

The tone parameters include the colors of each main tone in a sequence, and each color in the tone parameters is sequentially obtained according to the preset ambient light control interval, and the atmosphere light control time is used to control the time of each tone in the atmosphere light. Display time; for example, when the ambient light control time is set to 1s, the ambient light will read a color in the hue parameter every 1s, corresponding to the output; the screenshot interval of each screen image is 120s, so according to each image When the generated hue parameters control the output of the ambient light, it is necessary to read the color of each main hue multiple times in a sequential order;

Query whether the preset color library of the ambient light has the read color, that is, whether the ambient light supports displaying the read color;

When the color is available in the color library, the ambient light supports displaying the read color, and controls the ambient light to output the corresponding hue light with the color value corresponding to the color;

When the color does not exist in the color library, the ambient light does not support displaying the read color, a color is randomly selected in the color library, and the corresponding color value of the selected color is used to control the output of the corresponding tone of the ambient light light.

It should be noted that the ambient light control time and the screenshot interval time in this embodiment are examples, and may be other values in other embodiments.

It should be noted that the color library is the initial setting of the ambient light, including the color values of all the colors that the ambient light can display, and when matching, the color value is used for matching;

By analyzing whether each color in the hue parameter matches the supported color of the ambient light, and replacing the unmatched color with random other colors, there is no need to identify the color based on the supported color of the ambient light when the algorithm is the main color, which will lead to a sharp increase in computing power Occupation, can solve the problem of color mismatch quickly and easily.
