Example one

Fig. 1 is a schematic flowchart illustrating a light rhythm method according to an embodiment of the present application, where an execution subject of the method may be a terminal device, such as a light effect driving device, and in this embodiment, the light rhythm method is described by taking the light effect driving device as an example, as shown in fig. 1, and the light rhythm method may include the following steps:

step S101, target audio data are obtained, the target audio data are processed, and decibel values corresponding to the target audio data are determined.

In this embodiment, lamp effect drive arrangement can acquire the target audio data that PC host computer, display etc. can send the equipment of signal to lamp effect drive arrangement and send to carry out corresponding processing to target audio data based on the sender, so that it is luminous according to the corresponding lamp pearl of decibel value control that determines, thereby realizes audio frequency light rhythm. The display can be a desktop display, a portable electronic display, such as a Mini Led, an OLED and other high-end displays, the display can be applied to a household desk, and the lamp bead can be an eye protection lamp, a household atmosphere lamp and the like on the display.

For example, as shown in fig. 2, the PC host may send digital audio data to the display through signals such as HDML, DP, Type-C, etc., so that after a Scaler chip in an AD board of the display processes the digital audio data into target audio data, the target audio data is sent to a CH340 serial port protocol chip in the lamp effect driving device, and the chip sends the target audio data to a CX32L003 chip in the lamp effect driving device, so as to drive the lamp beads to emit light; the PC host can also process audio data by utilizing PC control software inside the PC host to obtain target audio data, then sends the target audio data to the display through a USB signal, and then sends the target audio data to a CH340 serial port protocol chip in the lamp effect driving device through the USB signal by the display, and the chip sends the target audio data to a CX32L003 chip in the lamp effect driving device so as to drive the lamp beads to emit light. The Scaler chip has the audio decoding capability of digital audio data, so that the light effect rhythm of the Scaler level is realized; above-mentioned CX32L003 chip possesses high-speed SPI drive IO mouth for having the high-speed singlechip of Cortex-M0 kernel, and this chip can drive all kinds of lamp pearls. It can be understood that, because the lamp effect driving device has more lamps connected, the lamp effect driving device can be connected with the AD board of the display in an external hanging manner, and can perform IIC communication with the AD board.

In one embodiment, the step S101 may include, whether the target audio data is sent from the PC host or the display: the driving device obtains the format of the target audio data and splits the target audio data into audio data corresponding to left and right sound channels according to the format.

For example, if the format of the target audio data is a PCM 16-bit audio data format, it is described that audio data corresponding to left and right channels in audio data in one period respectively occupy two bytes, and an alternate storage manner is adopted, that is, the audio data in one period sequentially includes left channel data of 2 bytes, right channel data of 2 bytes, left channel data of 2 bytes, and the like, which are sequentially circulated, so that the audio data can be split by a For circulation means according to the storage period of the audio data, and thus audio data corresponding to the left and right channels respectively is obtained.

In an embodiment, the splitting the target audio data into audio data corresponding to left and right channels may further include: when the display processes the target audio data, a processing chip in the display may split the target audio data to obtain audio data corresponding to the left and right channels, where the processing chip may be an AD83586 chip; when the target audio data is obtained by the processing of the PC host, the target audio data can be split by the PC host, so that the audio data corresponding to the left channel and the right channel respectively can be obtained.

Correspondingly, the corresponding decibel values of the audio data corresponding to the split left and right sound channels can be calculated according to a preset algorithm. For example, the left channel corresponds to a left decibel value of:

left decibel value (absolute value of sum of audio data corresponding to left channel) 400/(total number of collected audio data/2 × 2¹⁶)

The right decibel values for the right channel are:

right decibel value (absolute value of sum of audio data corresponding to right channel) 400/(total number of collected audio data/2 × 2¹⁶)

Accordingly, when obtaining the decibel values of the audio data corresponding to the left and right channels, respectively, the following step S103 may include: and driving the lamp beads corresponding to the left and right sound channels on the display to emit light simultaneously according to the number of the lamp beads and/or the brightness of the lamp beads. For example, as shown in fig. 3, if the regions E and F in fig. 3 represent the light strip composed of a preset number of light beads, the regions E and F may correspond to the left channel and the right channel, respectively, so that the light rhythm can be realized by controlling the light beads in the light strip corresponding to the regions E and F, respectively.

In an embodiment, the lamp effect driving apparatus may perform fault tolerance processing on the decibel value, and the step S101 may include: judging the decibel value and a preset first preset threshold value and a preset second preset threshold value to determine whether the decibel value exceeds the range or not, and determining whether the decibel value needs to be corrected or not according to a judgment result, specifically, if the decibel value is greater than the first preset threshold value, determining the first preset threshold value as the decibel value; and if the decibel value is smaller than a second preset threshold, determining the second preset threshold as the decibel value.

In one embodiment, because the audio rhythm he has the beat, the audio droplet audio corresponds the light rhythm when the beat is too fast and can lead to the lamp pearl that constitutes the lamp area to link together, and can not see the light rhythm effect that the audio droplet audio corresponds, or the light rhythm effect is relatively poor, so can select the audio data of presetting the frame in 30 frames to 40 frames range and handle, cause the audio can not too fast, also can not too slow to improve visual effect.

And S102, determining the quantity of the lamp beads and/or the brightness of the lamp beads corresponding to the decibel values according to a preset mapping relation.

In this embodiment, the light effect driving device establishes the mapping relationship between the decibel value of the audio frequency and the lamp beads in advance, so that the number of the light emitted by the lamp beads and the brightness of the light emitted by the lamp beads are determined according to the mapping relationship, and the light rhythm is realized. It can be understood that the brightness of the light emitted by different lamp beads at the same time can be different according to the decibel value.

In an embodiment, before step S102, a mapping relationship between the lamp bead and the decibel value needs to be constructed, which may specifically include: the linear mapping or the linear mapping of the line segments can be established according to the range value of the decibel value and the number of the lamp beads, and the linear mapping or the linear mapping of the line segments can be established according to the range value of the decibel value and the range value of the brightness of the lamp beads, so that the aim of controlling the number and the brightness of the lamp beads to change along with the audio decibel value is fulfilled.

Exemplarily, if the range value of the set decibel value is 0-100 and the number of the actual driving lamp beads is also 100, a linear mapping relation of 1:1 can be established; if the number of the actual driving lamp beads is 10, a linear mapping relation of 10:1 can be established. In addition, a linear mapping relationship of the line segments can be established according to user requirements, for example, if the range value of the set decibel value is 0-100 and the number of the actual drive bulbs is 10, the linear relationship is respectively established by controlling the decibel value range value of 0-20 to correspond to 1, the decibel value range value of 20-80 to correspond to 6, and the decibel value range value of 80-100 to correspond to 3.

And S103, driving corresponding lamp beads on the display to emit light according to the number of the lamp beads and/or the brightness of the lamp beads.

In this embodiment, the lamp effect driving device may drive the lamp beads on the display according to the determined number of the lamp beads and/or the brightness of the lamp beads, for example, simultaneously and respectively control the lamp beads in the areas E and F in fig. 3, which correspond to the corresponding number of the lamp beads, to emit light, and control the light-emitting brightness of the currently-emitted lamp beads.

In an embodiment, the light rhythm may be performed according to the picture, which may specifically include: the lamp effect driving device acquires color information of at least one target area on a display picture, determines the color of the corresponding lamp bead of at least one lamp bead according to the color information of the at least one target area, and drives the corresponding lamp bead on the display to emit light according to the color of the lamp bead of the at least one lamp bead. The target area can be an area divided on a display picture, and the color of the lamp beads is the color displayed when the lamp beads emit light.

For example, as shown in fig. 2, the PC host may send digital picture data of a display picture to the display through signals such as HDML, DP, Type-C, etc., so that after a Scaler chip in an AD board of the display processes the display picture to obtain color information of at least one target region on the display picture, the color information is sent to a CH340 serial port protocol chip in the lamp effect driving device, and the chip sends the color information to a CX32L003 chip in the lamp effect driving device, so as to drive a lamp bead to emit light; the PC host can also process the display picture by using its internal PC control software to obtain the color information of at least one target area, and then send the color information to the display through a USB signal, and then the display sends the color information to a CH340 serial protocol chip in the lamp effect driving device through a USB signal, and the chip sends the color information to a CX32L003 chip in the lamp effect driving device, so as to drive the lamp beads to emit light, as shown in fig. 3, the lamp beads corresponding to the area a, the area B, the area C, the area D, the area E, and the area F in the back of the display in fig. 3 can be controlled according to the color information to emit light of corresponding colors. The Scaler chip has the capability of analyzing the color tone of a large area of a picture, so that the light effect rhythm of the Scaler level is realized; the lamp beads in the area A, the area B, the area C and the area D in the figure 3 can be spotlight lamp beads.

Exemplarily, if a lamp bead on a display is an MCU lamp bead with a built-IN chip, the MCU lamp bead comprises four interfaces, namely VCC/IO, GND/IO, IN/IO and OUT/IO, VCC and GND are power supply pins, IN is a signal input interface and OUT is a signal output interface, if it is desired to drive the lamp bead to be bright, it is only necessary to use one input interface to send RGB three-color coordinate values, one lamp bead can correspond to 24BIT data, 24BIT data needs to include coordinate values corresponding to red, green and blue three colors, that is, every 8BIT data corresponds to one color, data can be sent IN the order of GRB, and the range is 0-255.

If the current lamp beads are connected in parallel, the instruction ports corresponding to the lamp beads can be connected in series, namely, the output of the previous lamp bead is connected with the input of the next lamp bead, so that when the lamp effect driving device sends an instruction for driving the lamp beads to emit light correspondingly, the instruction data corresponding to the lamp beads are sent together, namely, an instruction is generated, when the current lamp bead receives one 24BIT data in the instruction, the received 24BIT data is intercepted, and the rest instruction data is sent to the next lamp bead connected with the current lamp bead, so that all lamps are driven to emit light, for example, 100 lamp beads need to be driven currently, and the 100 lamp beads are connected in parallel, so that 100 × 24BIT 2400BIT data is needed.

It can be understood that drive arrangement can drive the lamp pearl jointly according to the lamp pearl quantity that obtains, lamp pearl luminance and lamp pearl colour and give out light to realize making real-time rhythm of light according to picture and audio frequency, through the interaction of audio and video and light of scenes such as recreation, film, cause to immerse and feel better, still when the crowd that can face the bad hearing, impel the crowd that the bad hearing to experience the atmosphere of scene through the light rhythm of scene. In addition, a competitive element can be added to the display, and real-time rhythm can be realized.

Example two

Fig. 4 is a schematic flowchart illustrating a light-pulse method according to an embodiment of the present application, where an execution subject of the method may be a terminal device, such as a PC host, and in this embodiment, a PC host is taken as an example for description, as shown in fig. 4, the light-pulse method may include the following steps:

step S401, obtaining an audio rhythm instruction, and determining a target audio endpoint from a preset audio endpoint table according to the audio rhythm instruction.

In this embodiment, in some electronic contest scenes, the PC host may be connected to obtain multimedia information, where the multimedia information includes audio information and video information, and when the PC host obtains an audio rhythm instruction, it indicates that an audio rhythm is currently required, the PC host determines a target audio endpoint from a preset audio endpoint table so as to obtain audio data in the target audio endpoint, and may quickly determine the target audio endpoint as required according to the preset audio endpoint table, thereby quickly capturing the audio data, and further providing basic data for implementing rhythm implementation based on audio for subsequent lights. The audio endpoint is a device capable of playing audio, that is, a device having an audio output channel, including but not limited to a display audio device, a bluetooth headset, an inserted headset, a PC speaker, etc.; the target audio endpoint is an audio endpoint of the currently played audio of the PC host.

Specifically, the PC host may determine, through an API function of a COM component in the Window system, an audio endpoint currently being played, that is, the target audio endpoint. If two or more than two audio endpoints exist, selecting the audio endpoint needing light rhythm from the currently played audio endpoints according to preset requirement information, and determining the selected audio endpoint as a target audio endpoint. The above requirement information includes the priority order of the audio endpoints, the preset number of audio endpoint combinations, and the like, and it can be understood that if the audio light rhythm is based on the overall audio rhythm, the effect is better, so that mixed audio can be generated according to the preset number of audio endpoint combinations, and if the music is currently played and the game is played, the mixed audio data can be obtained to perform the audio light rhythm.

In one embodiment, the PC host detects audio endpoints in advance, thereby generating an audio endpoint table from the detected audio endpoints. Specifically, the output audio data may be detected by a COM component API interface program in the Window system, and each audio endpoint is enumerated, so that an audio endpoint table is generated according to each enumerated audio endpoint.

In an embodiment, the acquiring of the audio data in the target audio endpoint before step S402 may specifically include: the target endpoint can be copied to the client audio function through an Active function carried by a Window while the target endpoint is activated, and the target endpoint is initialized, the initialized endpoint is used for establishing an audio channel of a mapping relation, the initialized endpoint is equivalent to a storage control and is used for storing audio data, so that the audio data in the target endpoint can be copied, the audio data is copied to the client audio function, a complete mapping relation is realized, an original audio file is not required to be processed, and data analysis and algorithm processing are performed on the basis of not influencing the original video file.

And S402, converting the audio data in the target audio endpoint into a preset format to obtain target audio data.

In this embodiment, because different audio formats, bit depths, and channel numbers may be different, for example, there are 8 bit/16 bit/24 bit audio data, the format conversion may be performed on the audio data through PC control software installed in the PC host, so as to facilitate subsequent processing through a unified format, for example, the PC host may uniformly convert the acquired audio data into a 16 bit PCM dual-channel format, thereby implementing a dual-channel L/R audio rhythm; because the audio playing frequency of the computer is basically 44KHz, and some audio data do not meet the sampling rate, the audio data can be normalized, so that the audio data meet the sampling rate.

In an embodiment, a sharing mode may be further set for the audio data of the target endpoint, and a service corresponding to the sharing mode is started, where the service is started means that the audio data after format conversion can be called and processed by other tasks. It can be understood that the function module in the Window system may be set to the sharing mode or the exclusive mode, and the difference between the two modes is whether the function module can be called by other tasks, for example, applications such as QQ, WeChat, Tencent meeting, beauty Camera, etc. can call the camera function of the computer, so the function module needs to be set to the sharing mode so that each application can call the function module; if the mode is set as the exclusive mode, after the QQ is turned on, the thread task occupies the camera function, so that the applications such as Tencent meeting, WeChat, beauty camera and the like cannot call the service. Accordingly, although the audio data of the target audio endpoint is arranged, the target audio endpoint is also one of the audios, and thus, the target audio endpoint also needs to be set to the sharing mode so that other tasks can call the processing.

And step S403, sending the target audio data to a lamp effect driving device, so that the lamp effect driving device drives a corresponding lamp bead on a display to emit light according to the target audio data.

In this embodiment, the PC host sends the processed audio data, that is, the target audio data, to the light effect driving device to implement the rhythm of the audio light, and the light effect corresponding to the audio data obtained through the processing of the PC host is finer and finer. The first embodiment is referred to as a method for driving a corresponding lamp bead on a display to emit light by a lamp effect driving device.

Exemplarily, as shown in fig. 2, the PC host sends the target audio data to the display through a USB signal, and then the display sends the target audio data to the CH340 serial port protocol chip in the lamp effect driving device through the USB signal, and then the chip sends the target audio data to the CX32L003 chip in the lamp effect driving device, so as to drive the lamp bead to emit light.

In an embodiment, the light rhythm may be performed according to the picture, which may specifically include: the method comprises the steps that a PC host obtains a picture rhythm instruction, determines a display picture according to the picture rhythm instruction, and obtains lamp bead arrangement information, wherein the lamp bead arrangement information is the arrangement position of lamp beads on a display, and divides the display picture into at least one target area according to the lamp bead arrangement information, as shown in figure 3, the target area is an area A, an area B, an area C, an area D, an area E and an area F which are arranged on the back of the display in figure 3 respectively, the color information of at least one pixel point in the target area is determined, and the corresponding relation between the pixel point and the lamp beads in the target area can be set; and sending the color information of at least one pixel point in the target area to the lamp effect driving device, so that the lamp effect driving device drives the lamp bead corresponding to the pixel point on the display to emit light according to the color information of the at least one pixel point.

In this embodiment, the display image is processed by PC control software installed in the PC host to obtain color information of at least one pixel point in the target area, and the PC host sends the color information of at least one pixel point in the target area to the lamp effect driving device to implement rhythm of video light, so that the light follows the PC image to implement fixed point and regional color rhythm, and the number of comparison points between the display image and the lamp bead can be increased by processing the color information of at least one pixel point in the target area obtained by the PC host.

It can be understood that, in order to improve the light rhythm effect, a pixel point may be set to correspond to a lamp bead corresponding to the pixel point, that is, what color the pixel point is, and what color the lamp bead corresponding to the pixel point is, so that the light-emitting direction and color of the lamp bead are maintained to be displayed synchronously with the display picture, for example, the colors of the four corners of the display picture are red, and then the light effect colors of the area a, the area B, the area C, and the area D in fig. 3 are also red.

Exemplarily, as shown in fig. 2, the PC host sends the color information of at least one pixel point in the target region to the display through the USB signal, and then the display sends the color information of at least one pixel point in the target region to the CH340 serial port protocol chip in the lamp effect driving device through the USB signal, and then the chip sends the color information of at least one pixel point in the target region to the CX32L003 chip in the lamp effect driving device, so as to drive the lamp bead to emit light.

In one embodiment, the PC host may determine color information of at least one pixel point in the target area by collecting the pixel points in the target area to perform reading. Specifically, extracting fixed pixels from the target area, for example, acquiring data information of the top left corner of the screen, and acquiring color information of the coordinate (0,0) by using a screen color extracting tool getcolor (0, 0).

In an embodiment, before dividing the display screen into at least one target area according to the bead arrangement information, the method may further include: the PC host acquires desktop information; determining a content display area on a preset virtual screen according to the desktop information, wherein the size of the content display area is consistent with that of a display area on the display; and mapping the display picture to the content display area.

Specifically, the display information of the display is determined by obtaining a handle HDC of the real display, and then desktop information of the display is determined by a Get systemetrics function in the API, for example, the desktop size in the desktop information is 1920 × 1080pix (1080P), a bitmap object with the same size as the desktop is created, and a bitmap area with the same size as the desktop is created, where the bitmap area is the content display area, where the bitmap object is a variable used for storing a picture address in a bitmap format, and the bitmap area is where a bitmap picture is displayed.

In an embodiment, before determining the content display area on the preset virtual screen, a virtual screen needs to be created, which may specifically include: and creating a virtual screen according to the display information through a CreatCompatibleDC function in the window system API, wherein the returned handle is hCompDC. It can be understood that if the image capture process is directly performed on the PC-side real display, the problem of image stutter or continuous mouse shaking can be caused. Therefore, in this embodiment, the display picture can be captured in real time, and the display picture can be converted into a picture in a bmp format to be displayed on the created virtual screen, so that the picture of the real display can be shared on the virtual screen in real time, and then the picture on the virtual screen is obtained, thereby avoiding the problem that the picture of the real display is abnormal.

In one embodiment, the PC control software can be further used for performing personalized setting, setting a preset mode, and matching rhythm settings corresponding to the preset mode, where the rhythm settings include: respiratory rate, pulse color, etc.

In the embodiment of the application, an audio rhythm instruction is acquired, a target audio endpoint is determined from a preset audio endpoint table according to the audio rhythm instruction, audio data in the target audio endpoint are converted into a preset format to obtain target audio data, and finally the target audio data are sent to a light effect driving device, so that the light effect driving device drives corresponding lamp beads on a display to emit light according to the target audio data, and accordingly the number of the light emitted by the lamp beads and/or the brightness of the light emitted by the light are controlled to correspondingly change according to decibel values corresponding to the audio data, and the light effect displayed on the display meets the requirements of a specific scene.

EXAMPLE III

Fig. 5 is a schematic flowchart illustrating a light rhythm method in an embodiment of the present application, where an execution subject of the method may be a terminal device, such as a display, and in this embodiment, the display is taken as an example for description, and as shown in fig. 5, the light rhythm method may include the following steps:

step S501, obtaining an audio rhythm instruction.

In this embodiment, in some electronic contest scenarios, there are cases where non-PC devices are connected, for example, devices such as PS5, XBOX, Switch, DVD, and the like, because there is no USB channel, multimedia information can be processed through the display, and when a scaler chip in the display acquires an audio rhythm instruction, digital audio information in digital multimedia information acquired through the HDMI and DP interfaces is processed and output through the IIS, thereby realizing audio light rhythm.

Step S502, converting the digital audio data into analog audio data according to the audio rhythm instruction.

In this embodiment, the display may convert the digital audio data obtained by the AD83586 chip into analog audio data, so as to send the converted analog audio data to the lamp effect driving device, and in addition, the display may also send the converted analog audio data to the earphone.

In one embodiment, before step S502, the digital audio data may be divided into two parts, one part of which is executed in step S502, and the other part of which is converted into an analog signal by processing the digital audio data through the AD83586 chip, so as to realize shunting of the display audio and meet the requirements of three sound sources, namely, an earphone, a speaker, and an audio rhythm. It can be understood that the audio output of the display can be output through an AudioOut earphone hole and can also be output through a loudspeaker connected with a power amplifier, and if the digital audio data acquired by the display is directly processed at present, the situation that the interface does not meet the requirement may exist, so that the digital audio data needs to be subjected to shunt processing.
