[0046] The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.

[0047] As Figure 1 shown, a light strip controller provided by an embodiment of the present application includes at least two HHDMI interfaces 100, an HDMI processing unit 102, and a control unit 104. Among them,

[0048] At least two HDMI interfaces 100 for obtaining video stream data in HDMI format; wherein, the video stream data includes at least one video frame image; exemplarily, the at least two HDMI interfaces 100 may include a first HDMI interface 1001 and a second HDMI interface 1002.

[0049] An HDMI processing unit 102 for processing a first video frame image to obtain first edge color information; wherein, the first video frame image is any one of the at least one video frame image;

[0050] In some embodiments, the implementation process of obtaining the first edge color information by processing the first video frame image through the HDMI processing unit may include: the HDMI processing unit obtains the pixel information of the first video frame image, and processes the pixel information of the first video frame image based on an image edge detection algorithm to obtain the first edge color information. For the implementation manner of processing the pixels of the first video frame image by the image edge detection algorithm, please refer to the prior art and will not be elaborated here.

[0051] A control unit 104 for controlling the light strip to display according to the first edge color information.

[0052] In some embodiments, the implementation process of controlling the light strip to display according to the first edge color information by the control unit 104 may include: performing interpolation processing on the first edge color information to obtain second edge color information, so that the light strip can be controlled to display according to the second edge color information. This implementation manner can match the flashing rate of the light strip with the image information and enrich the display effect of the light strip.

[0053] In some embodiments, the flashing rate of the light strip is consistent with the switching rate of the video frame images in the video stream data, and this implementation manner can make the display effect of the light strip perfectly match the video image content.

[0054] As Figure 2 shown, another light strip controller provided by an embodiment of the present application includes a configuration unit 106, at least two HDMI interfaces 100, an HDMI processing unit 102, and a control unit 104; wherein,

[0055] A configuration unit 106 for obtaining configuration information; wherein, the configuration information indicates the parameter information of the light strip; exemplarily, the parameter information of the light strip includes light strip partition information and light strip structure information.

[0056] At least two HDMI interfaces 100 for obtaining video stream data in HDMI format; wherein, the video stream data includes at least one video frame image;

[0057] The HDMI processing unit 102 is configured to obtain pixel information of a first video frame image according to configuration information, and process the pixel information of the first video frame image based on an image edge detection algorithm to obtain first edge color information; wherein, the first video frame image is any one of at least one video frame image.

[0058] In the prior art, image data of four sides, namely top, bottom, left, and right, are often extracted from video stream data as basic data for strip display. However, if only the information of a single line at the screen edge is extracted for strip display, a satisfactory display effect cannot be obtained.

[0059] Based on this, the HDMI processing unit can obtain pixel information that is superior to the above-mentioned basic data according to configuration information. This implementation fully considers the partition information and strip structure information of the strip. The following is a specific elaboration:

[0060] In some embodiments, when the strip structure information indicates that the strip is a disconnected strip, calculate the coordinate range of each disconnected strip according to the length of each disconnected strip, the interval between multiple disconnected strips, and the display resolution of each disconnected strip, so that pixel information within the same coordinate range can be obtained from the first video frame image according to the coordinate range of each disconnected strip. Since this implementation considers the partition information and strip structure information of the strip, abnormal display effects can be avoided, and the display effect can be further enriched.

[0061] In some embodiments, when the strip structure information indicates that the strip is a continuous strip, calculate the coordinate range of each partition of the continuous strip according to the display resolution of the strip and the strip partition information, so that pixel information within the same coordinate range can be obtained from the first video frame image according to the coordinate range of each partition of the continuous strip. Since this implementation considers the partition information and strip structure information of the strip, abnormal display effects can be avoided, and the display effect can be further enriched.

[0062] The control unit 104 is configured to control the strip to display according to the first edge color information.

[0063] In some embodiments, the implementation process of controlling the strip to display by the control unit 104 according to the first edge color information may include: performing interpolation processing on the first edge color information to obtain second edge color information, so that the strip can be controlled to display according to the second edge color information. This implementation can match the flashing rate of the strip with the image information and enrich the display effect of the strip.

[0064] In some embodiments, the flashing rate of the light strip is consistent with the switching rate of the video frame images in the video stream data. This implementation can make the display effect of the light strip perfectly match the video image content.

[0065] It should be noted that, based on Figure 2 the structure shown, the light strip controller and the mobile terminal are located in the same local area network (for example, the light strip controller and the mobile terminal are connected through WiFi), and the configuration information can be configured through the control interface of the mobile terminal (for example, selecting the working mode of the light strip and the HDMI output mode), so that the light strip controller can receive the above configuration information.

[0066] It should also be noted that after the light strip controller obtains the first edge color information, it can also control the opening and closing of the light strip in combination with the volume information, which improves the user experience compared with the manual opening and closing method.

[0067] It should also be noted that after the light strip controller obtains the first edge color information, it can also drive the light strip to perform color expansion in combination with the volume information and the instructions input by the user. It should also be noted that in practical applications, the above Figure 1 、 Figure 2 shown light strip controller may also include an HDMI output interface for driving other display devices, such as a monitor.

[0068] In summary, after the light strip controller obtains the video stream data, it can process the video frame images in the video stream data to obtain edge color information, and thus control the light strip to display according to the obtained edge color information. This implementation takes into account the video playback content, can better match the environmental scene, and enriches the user's entertainment experience.

[0069] Next, taking the Figure 1 shown light strip controller as an example, a method for controlling the display of the light strip provided by the embodiments of the present application will be described.

[0070] Step 300: Obtain HDMI format video stream data through the at least two HDMI interfaces; wherein, the video stream data includes at least one video frame image;

[0071] Step S302: Process the first video frame image through the HDMI processing unit to obtain first edge color information; wherein, the first video frame image is any one of the at least one video frame image;
