The video signal is collected by the capture card of the capture box, and the color analysis processing unit performs color analysis and light address encoding.

[0049] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be interpreted as limiting the present application.

[0051] refer to Figure 2 As shown, Figure 2 The present invention is a schematic diagram of the structure of a lighting color control system of an embodiment, which is applied to a video player and can be integrated into the operating system of the video player, and includes: an embedded graphic display system, a lighting color processing unit and a lighting address encoding unit.

[0052] Among them, the embedded graphic display system is used to collect video signals from the video source and obtain image pictures; the lighting color processing unit is used to perform color analysis on the image pictures to obtain color data; the lighting address encoding unit is used to perform address encoding on the lighting equipment according to the color data to generate lighting control parameters, and output the lighting control parameters to the lighting driver to drive the lighting equipment to emit light, so that the lighting color of the lighting equipment changes with the image pictures output by the video player to the display screen.

[0053] Compared with the rear capture box solution of conventional technology, the present application integrates a lighting color control system on a video player, thereby reducing the equipment cost and engineering implementation cost in lighting color control; the video signal is captured from the video source through an embedded graphic display system, and the color data of the picture image is obtained before the video signal is played and rendered, and the lighting control parameters are generated. The lighting color has good synchronization and followability with the video picture, thereby improving the lighting color control effect; since the color data obtained by the lighting color processing unit can be adjusted according to different needs, different lighting mode settings and lighting control parameter controls can be realized, so that different required lighting effects can be freely configured in the lighting color control.

[0054] In one embodiment, the light address encoding unit of the light color control system is also used to adjust the light mode and light control parameters output by the light color control system according to the configuration information input by the user in the UI (User Interface Designer) interface of the video player.

[0055] Specifically, the lighting color control system is integrated on the video player, and the configuration information can be inputted through the UI interface of the host computer of the video player, and the lighting color control system can be customized to configure the output lighting mode and lighting control parameters; thus, there is no need to add an additional control module.

[0056] For example, by using a host computer of a video player, such as a computer, a mobile terminal, etc., a configuration program and a configuration interface can be added by using the UI interface of the host computer to realize the configuration function of the lighting color control system.

[0057] In one embodiment, the lighting color control system is characterized in that it also includes: an audio processing unit, used to obtain input audio data, perform FFT processing on each channel of the audio data to obtain spectrum data; extract key frequency points from the spectrum data to obtain sound intensity information; and superimpose the sound intensity information on the control parameters to control the lighting color effect of the light strip.

[0058] refer to Figure 3 As shown, Figure 3 This is a system block diagram of an example video player, in which the hardware layer mainly includes input / output devices, a host and a graphics card; wherein the input / output devices are mainly used to realize human-computer interaction functions, input configuration information, display UI interfaces, etc. The host mainly includes the CPU, memory and other motherboard circuits, etc.; the graphics card is used to render video signals, usually using a GPU as the core to realize image rendering operations, and output through an HDMI interface. In the system software layer, it is mainly the operating system of the video player, such as the Android system; in the application software layer, it is mainly various application software, and the lighting color control system provided in this application is pre-installed on the operating system, in which the player can play the video signal and render it through the graphics card; the configuration program can use the input / output device to realize the upper computer configuration function, and the user inputs the configuration information and sets it to the lighting color control system through the configuration program to change the lighting control parameters, etc.

[0059] In one embodiment, the lighting color control system and the lighting color processing unit of the present application are configured to adjust the resolution of an image to obtain a reduced image; perform Gaussian blur processing on the reduced image according to a set first Gaussian blur parameter to obtain a first blurred image, and perform Gaussian blur processing on the first blurred image according to the set first Gaussian blur parameter to obtain a second blurred image; perform color sampling processing on the blurred image according to the matching range of the light strip to obtain color data; wherein the first blurred image is used for dynamic mode control, and the second blurred image is used for atmosphere mode control.

[0060] As in the solution of the above embodiment, by using the first blurred image and the second blurred image as the basic picture of light following shadow movement, the effect of freely controlling the lighting mode can be achieved.

[0061] In one embodiment, in the lighting color control system of the present application, the lighting color processing unit is also configured to perform parallel scanning of the image in the horizontal direction; perform vertical scanning using multiple scanning lines on the image, and calculate the length of the black border of the image; and calculate the image within the black border range based on the black border length.

[0062] As in the solution of the above embodiment, the black edges of the video signal are automatically detected first, which can avoid the defect that the light color cannot follow the changes of the image screen due to the upper and lower black edges on the video screen.

[0063] Based on the lighting color control system of the present application, a lighting color control method for realizing the function of the lighting color control system is provided below; Figure 4 As shown, Figure 4 The present invention is a flow chart of a lighting color control method according to an embodiment, comprising:

[0064] Step S10, acquiring a video signal and an image frame, and adjusting the resolution of the image frame to obtain a reduced image.

[0065] In this step, the video signal on the TV screen can be obtained and the image can be obtained, or the video signal can be accessed externally and the image can be obtained, and then the resolution of each frame of the image can be adjusted to a small-sized reduced image, so that a native control solution can be implemented within the image system.

[0066] In one embodiment, in view of the defect in conventional technology that the upper and lower lights cannot be turned on when the video image has upper and lower black edges, the light color control system of the present application, before adjusting the resolution of the image to obtain a reduced image in step S10, further includes:

[0067] S101, performing parallel scanning on the image in the horizontal direction.

[0068] Specifically, each frame of the image is extracted from the input video, and then automatic black edge detection is performed, firstly performing horizontal parallel scanning; illustratively, the image can be scanned in parallel from left to right in the horizontal direction, and when there is no black edge in the scan, it is determined that there is no black edge in the horizontal direction; for example, the position between 2% and 98% can be scanned from left to right, and once non-black is found, the detection is terminated, and it is determined that the current image has no black edge.

[0069] S102, using a plurality of scanning lines on the image screen to perform vertical scanning, and calculating the length of the black border of the image screen.

[0070] Exemplarily, the method of scanning and calculating the black edge length in step S102 may include the following:

[0071] a) A plurality of distributed vertical lines are set in the vertical direction of the image screen, and the black screen length value is obtained by scanning from the upper and lower sides of the image screen toward the center along the vertical lines.

[0072] Specifically, vertical line scanning can be performed on the image screen. There are multiple scanning lines that are evenly distributed on the image screen. For example, the scanning is performed from the upper and lower directions to the center line, and then the length of the black is calculated. Assuming there are 5 scanning lines, 10 numbers are obtained by scanning, representing the black lengths in 10 vertical directions.

[0073] b) calculating the average black edge length according to the black screen length value, and calculating the black edge length of the image according to a plurality of black screen length values ​​with similar values.

[0074] Specifically, the scan data that is obviously larger than the mean value can be removed to prevent the black in the image from interfering with the real black edge. In the remaining scan data, the variance is less than a threshold, that is, the length of the black edge in each place is basically the same, and the mean value is calculated as the length of the black edge.

[0075] Preferably, in order to prevent the obtained black edge length mean from jumping, the historical value average can be calculated. For example, a queue can be used to record multiple (such as 8) latest historical data for use as a transition. Once it is detected that the image has no black edges, the queue is cleared.

[0076] S103, calculating the image frame within the black border range according to the black border length.

[0077] Specifically, according to the calculated black border length, an image within the black border range can be obtained as an original image for subsequent control of light color.

[0078] As in the above embodiment, Figure 5 As shown, Figure 5This is an example of image reduction. First, the video signal is automatically detected and the image is obtained. The black edges are removed and the light color is controlled by using the reduced image within the black edge range. This can avoid the defect that the light color cannot follow the changes of the image due to the upper and lower black edges on the video screen and realize fast color sampling processing.

[0079] Step S20, performing Gaussian blur processing on the reduced image according to the set Gaussian blur parameters to obtain a blurred image.

[0080] In this step, Gaussian blur parameters are set based on the lighting color control effect, and then the Gaussian blur parameters are used to perform Gaussian blur processing on the reduced image to obtain a blurred image as a basic image for lighting color control.

[0081] In one embodiment, in order to realize free control of lighting modes and more abundant color lighting control parameters; accordingly, the lighting color control system of the present application, such as Figure 6 As shown, Figure 6 is an exemplary Gaussian blur schematic diagram. Step S20 of performing Gaussian blur processing on the reduced image according to the set Gaussian blur parameters to obtain a blurred image may include:

[0082] S201, performing Gaussian blur processing on the reduced image according to a set first Gaussian blur parameter to obtain a first blurred image; wherein the first blurred image is used for dynamic mode control.

[0083] Exemplarily, the image within the black border range of the original picture is reduced to a small-sized image, and then a first Gaussian blur is performed on it to obtain a first blurred image.

[0084] S202, performing Gaussian blur processing on the first blurred image according to a set first Gaussian blur parameter to obtain a second blurred image; wherein the second blurred image is used for atmosphere mode control.

[0085] Exemplarily, the first blurred image is reduced to half its size, and then Gaussian blur is performed for the second time to obtain the second blurred image.

[0086] As in the scheme of the above-mentioned embodiment, a first blurred image is obtained by performing a first Gaussian blur on the reduced image of the original video screen, which is used for dynamic mode control, and is used as a high dynamic effect by utilizing the characteristics of high resolution and retention of more details; then, on this basis, the first blurred image is Gaussian blurred to obtain a second blurred image, which is used for atmosphere mode control, and the atmosphere light strip is controlled by utilizing the characteristics of a high degree of secondary blurred color mixing; these two blurred images are used as the basic images for subsequent light-following-shadow movement, thereby achieving the effect of freely controlling the lighting mode.

[0087] Step S30: performing color sampling processing on the blurred image according to the matching range of the light strip to obtain color data.

[0088] In this step, according to the matching of the light strip and the range of the image screen, the fuzzy image is used to perform color sampling to obtain color data for controlling the color of the color, so as to realize the solution of controlling the color of the ambient atmosphere of the video screen.

[0089] In one embodiment, the step S30 of performing color sampling processing on the blurred image according to the matching range of the light strip to obtain color data may include:

[0090] S301, determining a sampling radius according to the size of the edge range of the light strip matching the image screen.

[0091] Specifically, Figure 7 As shown, Figure 7 This is a schematic diagram of an example color sampling screen, which shows the sampling radius r determined by the edge range of the light strip matching the image screen; thus, the radius of the sampling position can be customized to control the style, such as precise sampling or fuzzy sampling.

[0092] S302: Calculate sampling coordinate ranges of four edges to be sampled in the blurred image according to the sampling radius.

[0093] Specifically, according to the determined sampling radius r, the sampling coordinate range of the four edges to be sampled in the blurred image can be calculated; thereby achieving adjustable color picking position and adjustable sampling band from the center of the image to the edge of the image.

[0094] like Figure 7 The first blurred image is taken as an example. If the radius is r, the size of the first blurred image is 240×160, and the sampling area size is 180×120. Taking the upper left corner as the origin, we can get the upper left corner sampling coordinate range x∈[0, 30], y∈[0, 20], and the sampling coordinate range x∈[180, 240], y∈[120, 160].

[0095] S303, performing pixel sampling processing from a sampling coordinate range of the blurred image according to a set order to obtain color data.

[0096] In one embodiment, the sampling process of step S303 may include the following:

[0097] (1) Pixel sampling is performed from the sampling coordinate range of the blurred image according to the set order to obtain a color array.

[0098] Specifically, according to the determined sampling coordinate range, the pixel color values ​​of four edges are sampled from the blurred image in a clockwise direction to obtain a basic color array.

[0099] (2) performing linear interpolation sampling on the pixels of the color array to obtain color data identical to that of the light strip;

[0100] Specifically, since the number of light-emitting units of the lighting device is not strictly equal to the size of the color array, the pixels are linearly interpolated and sampled to be enlarged or reduced, thereby obtaining the same color array as the light strip.

[0101] As in the solution of the above-mentioned embodiment, different radii are set based on the data of the blurred image, and the pixel color values ​​are extracted to obtain the color data for controlling the color of the light, thereby achieving accurate sampling of the color data of the video screen.

[0102] In one embodiment, during the sampling process of this embodiment, the color data may also be uniformly post-processed, such as the clockwise and counterclockwise rotation of the light strip, the starting corner of the installation, and the additional head light-emitting units that need to be skipped during installation.

[0103] Exemplarily, after the color data is sampled, the color is subsequently subjected to unified post-processing, including:

[0104] 1) Brightness;

[0105] 2) Saturation;

[0106] 3) Gamma correction;

[0107] 4) High brightness attenuation (compressing overly bright white light to avoid interference with video viewing);

[0108] 5) Optional palette color adjustment;

[0109] 6) Fixed coloring in test mode (fixed coloring of four-side light strips during installation test).

[0110] In one embodiment, during the sampling process of this embodiment, the color data required by all light-emitting units (lamp beads) has been obtained, but the data is a perfect clockwise data starting from the upper left corner, which does not necessarily match the actual installation situation of the light strip. Based on this, in this embodiment, a trimming process can also be performed on the sequence, including:

[0111] 1) Select the direction of the lamp beads (if the light strip is installed counterclockwise, the order needs to be reversed);

[0112] 2) Starting corner selection (offset the color sequence according to the starting point of the light strip installation);

[0113] 3) Starting point adjustment (moving forward and backward when the mounting point is not perfectly in the corner);

[0114] 4) Ignore the starting point (if there is a section of unused lamp beads before the installation point, additional offset is required);

[0115] 5) Dirty data elimination (in setting mode, used to eliminate tail residue).

[0116] In one embodiment, when the first blurred image and the second blurred image are generated in step S20, then in step S30, after the first blurred image is sampled to obtain the corresponding color, more details can be retained because it is only blurred once and has a high resolution, and it can be used as a high dynamic effect; after the second blurred image is sampled to obtain the corresponding color, because it is small in size and has undergone secondary blurring, the color mixing degree is higher, and it can be used as an atmosphere light strip.

[0117] Step S40, generating a lighting control parameter according to the color data to control the lighting color of the light strip.

[0118] In this step, based on the obtained color data, lighting control parameters can be generated to control the lighting color of the light strip; specifically, by adjusting the color data so that the color sequence is consistent with the actual installation of the light strip, lighting control parameters can be generated and sent to the lighting control device for display to achieve control of the ambient color.

[0119] For example, the lighting device may use pixel point lights of the type WS2812, so as to better match the changes in the picture and achieve the effect of synchronous changes of the light and the picture following the video picture.

[0120] As in the scheme of the above-mentioned embodiment, after obtaining the video signal and the image frame, the resolution is adjusted to obtain a reduced image, and Gaussian blur processing is performed on the reduced image to obtain a blurred image; color sampling processing is performed on the blurred image to obtain color data, and light control parameters are generated to control the light color of the light strip; this technical scheme can enhance the light color control effect based on the synchronized light color related to the video screen that is blurred outside the video screen.

[0121] In one embodiment, the technical solution of the present application can also be applied to point light sources such as DMX512. Accordingly, the lighting color control system of this embodiment can also include: using a regional image to extract a color area from the blurred image; performing Gaussian averaging on the color area to obtain a regional average color; and controlling the atmosphere light according to the average color.

[0122] Specifically, the regional image is cut out, and then Gaussian average color is taken to obtain the regional average color, which is used as the atmosphere light.

[0123] In one embodiment, the technical solution of the present application can also be combined with audio to control the change of light color. Accordingly, the light color control system of the present application also includes:

[0124] The input audio data is obtained, and each channel of the audio data is processed by FFT (fast Fourier transform) to obtain spectrum data; key frequency points are extracted from the spectrum data to obtain sound intensity information; and the sound intensity information is superimposed on the control parameter to control the light color effect of the light strip.

[0125] Exemplarily, the input audio data is received, and FFT processing is performed on the left channel, the right channel, and the mixed mono channel to obtain a spectrum data, and several key frequency points are taken to obtain their decibel information, which is combined with the sampled RGB values ​​of the color data of the four edges and referenced to the script environment. In the script, the colors of the four edges are superimposed through the audio spectrum information, thereby achieving the effect of the light color following the music linkage.

[0126] As in the above-mentioned embodiment, a rectangular or arbitrarily shaped color array can be quickly generated through video images and audio, and the color array is sent to the light strip for control to achieve a light color effect related to the video image outside the screen image.
