Exemplary method
As shown in fig. 1, an embodiment of the present invention provides a method for adjusting an ambience lamp based on a picture, specifically, the method includes the following steps:
s100, acquiring a video signal stream of a currently played video;
in this embodiment, the atmosphere lamp module controls to acquire a video signal stream of a currently played video, and taking a television as a display device as an example, the video signal stream sent by the television or a set top box or a network television box can be intercepted through an HDMI interface. Furthermore, considering that the subsequent atmosphere lamp needs to change in real time according to the played video, the atmosphere lamp module can process the video signal stream by delaying the played video and utilizing the delay time, so as to reduce the processing pressure of the atmosphere lamp module data and effectively reduce the manufacturing cost of the module. By the steps, the video signal stream of the current playing video is acquired in real time.
Step S200, acquiring a frame video image of each frame based on the video signal stream;
in the embodiment, the ambience light module acquires a frame video image of each frame after acquiring the video signal stream, for example, the frame rate of the display device in the prior art is typically 60 frames, 90 frames or 120 frames. The ambience light module needs to acquire 60, 90 and 120 frames of video images for processing within one second. Further in view of the processing capabilities of the atmosphere light module, the user or manufacturer may set a frame image acquisition rate of less than 60 frames per second to further control the manufacturing cost of the atmosphere light module.
Step S300, acquiring image data of the frame video image edge based on the frame video image;
in this embodiment, the ambience light module captures image data of an edge of the frame video image according to the acquired frame video image, that is, data of an outermost circle of image within a display range, where an amount of captured data varies with a pixel width of the captured image edge. By the step, the image data of the frame video image edge for controlling the atmosphere lamp parameters is obtained.
Step S400, the image data is partitioned to obtain a plurality of sections of image data;
in this embodiment, the atmosphere lamp module divides the acquired image data into partitions to obtain a plurality of segments of image data, the dividing method includes equally dividing along the edge of the image, the number of the partitions is determined according to the number of the beads of the atmosphere lamp, and when the atmosphere lamp is an integral luminescent material such as an OLED, the number of the partitions needs to be manually adjusted by a user. The acquired image data are divided into multiple sections of image data corresponding to the atmosphere lamp beads through the step, so that each lamp bead of the atmosphere lamp corresponds to each section of image data one to one, the matching discomfort between the atmosphere lamp and the display equipment is reduced, and the user experience is improved.
And S500, controlling the atmosphere lamp corresponding to each section of image data to adjust the light based on the plurality of sections of image data after partition division.
In this embodiment, the ambience lamp module controls the ambience lamps corresponding to each segment of image data to perform lamp light adjustment according to the multiple segments of image data obtained by partitioning, for example, when a certain segment of image data is color a and brightness b, the ambience lamps on the edge of the segment of image are correspondingly made to display light with color a and brightness b. Further, since the thicknesses of the frames of the display devices are different, for example, if there is a super-narrow frame television and a television with a less-narrow frame, the brightness of the light required to weaken the boundary sense of the super-narrow frame television is less than that of the television with a less-narrow frame, and an adjustment interface is provided for the user to adjust the brightness and color shift of the whole atmosphere lamp. Further, when the user feels that the colors displayed by the light and the colors of the edge of the picture are shifted integrally when the actual display device plays, for example, the colors displayed by the light are 90 degrees before the colors of the edge image, the adjustment can also be performed by the function of the shift. The method realizes that the color of the edge of the currently played video image is sent to the corresponding atmosphere lamp for displaying in real time, eliminates the picture boundary sense and brings better display effect for users.
As can be seen from the above, the atmosphere lamp adjusting method based on pictures provided by the embodiment of the present invention obtains a video signal stream of a currently played video; acquiring a frame video image of each frame based on the video signal stream; acquiring image data of the frame video image edge based on the frame video image; partitioning the image data to obtain a plurality of sections of image data; and controlling the atmosphere lamp corresponding to each section of image data to adjust the light based on the plurality of sections of image data after partition division. Compared with the prior art, the atmosphere lamp is arranged on the frame of the display device in advance, when a user uses the display device, the atmosphere lamp carries out light effect display with the same effect according to the display color and the brightness of the frame of the picture, the effect of weakening the boundary sense of the display device is achieved, more immersive use experience is provided for the user, and along with the increase of the number of the atmosphere lamps, the reduction of the size and the reduction of the distance, the sense of incongruity of the atmosphere lamp can be further eliminated, and the boundary sense of the display device is naturally weakened.
Specifically, in this embodiment, a television commonly used by a user is used as the display device, the atmosphere lamp module may be designed on a television frame by a television manufacturer, or may be an atmosphere lamp module purchased by the user and magnetically attracted to the television frame, and when the display device and the atmosphere lamp are other devices, the specific scheme in this embodiment may be referred to.
In one application scenario, the ambience light module acquires a video signal stream of a currently playing video.
Specifically, as shown in fig. 2, the step S100 includes:
step S101, detecting that an atmosphere lamp starting instruction is received;
and step S102, acquiring a video signal stream of the currently played video in real time through a video signal interface.
Wherein, before the step of obtaining the video signal stream of the currently played video, the method comprises:
the method comprises the steps of installing an atmosphere lamp on a frame of the display equipment in advance, wherein the atmosphere lamp further comprises a driving control unit connected with the atmosphere lamp.
For example, as shown in fig. 3, a user or a television manufacturer needs to mount a circle of atmosphere lamps on a television frame in advance, and the atmosphere lamps can be selectively mounted on a frame on the rear side of the television according to the actual brightness of the atmosphere lamps. In fig. 3, eight RGB lamp beads are respectively installed on the upper and lower sides of the television, and four RGB lamp beads are respectively installed on the left and right sides, for a total of 24 RGB lamp beads. When the atmosphere lamp is designed by a television manufacturer, a driving control unit connected with the atmosphere lamp is arranged in the television; when the atmosphere lamp is installed on the television frame by a user through magnetic attraction and the like, a drive control unit is connected with the atmosphere lamp.
When the atmosphere lamp module detects that an atmosphere lamp starting instruction is received, the atmosphere lamp module obtains a currently played video stream in real time through a video signal interface. The atmosphere lamp starting instruction is, for example, when a user presses a switch button of an atmosphere lamp module, and the like, the video signal interface is usually an audio/video output interface, such as an HDMI interface, of a set top box or a network television box. The method realizes the synchronous acquisition of the signals of the television playing videos.
In an application scene, the atmosphere lamp module acquires a frame video image of each frame based on the video signal stream;
for example, the ambience light module intercepts each frame of video image of the currently playing video according to the video signal stream. For example, when the currently playing video is a movie video with 24 frames, the ambience light module will acquire frame video images of 24 frames in 1 second. Further, if the currently played video is 4K60 frames of video or 120 frames of video, in order to effectively reduce the processing amount of the ambient light module data, control the manufacturing cost, and reduce the resolution or frame rate of the acquired video, for example, when the density of ambient light beads is not large, the 4K video signal stream may be compressed to 2K or 1080P; similarly, when the original video signal stream video is 120 frames of video, a frame video image may be acquired every 2 frames. The purposes of effectively reducing the calculated amount of the atmosphere lamp module and controlling the cost are achieved through the steps.
In an application scenario, the ambience lamp module acquires image data of an edge of a frame video image based on the frame video image.
Specifically, as shown in fig. 4, the step S300 includes:
step S301, acquiring image data of a preset width of the edge of the frame video image based on the frame video image;
step S302, the preset width includes a preset pixel width.
For example, the ambience light module captures image data of a preset width at an edge of a frame video image according to the acquired frame video image, where the preset width includes a pixel width, for example, when the pixel width is 3, image data of pixels in the outermost three circles of the display screen, including brightness and color values of each pixel, are acquired. Furthermore, according to the display effects of different displays, obtaining image data with different pixel widths also causes great discomfort to the color displayed by the atmosphere lamp finally, so that a user can adjust the overall display effect of the atmosphere lamp and the television by adjusting the parameter of the pixel width.
In an application scene, the atmosphere lamp module divides the image data into partitions to obtain multiple segments of image data;
specifically, as shown in fig. 5, the step S400 includes:
step S401, the image data is partitioned along the edge direction of the frame video image to obtain a plurality of sections of image data.
For example, after the image data is obtained, the ambience light module performs partition division on the image data along the edge direction of the frame video image, for example, when the current television is equipped with an ambience light as shown in fig. 3, the result of partition division on the image data along the edge direction is: the image data is divided into 24 segments, wherein the upper edge and the lower edge of the television are respectively provided with 8 segments of image data, the left edge and the right edge of the television are respectively provided with 4 segments of image data, and each segment of image data corresponds to the atmosphere lamp beads one by one. It can be seen that the number of segments for dividing the image data into regions is determined by the number and placement of the ambient light beads, and is generally distributed equally. The image data at the edge of the frame video image can be divided into a plurality of sections of image data through the step, so that each section of image data can be in one-to-one correspondence with each atmosphere lamp bead, and one atmosphere lamp bead is correspondingly controlled by one section of image data. And more accurate atmosphere light control is realized, so that the light is more natural and the boundary sense of a television picture is eliminated.
In an application scenario, the atmosphere lamp module controls the atmosphere lamp corresponding to each segment of image data to adjust the light based on the segmented image data.
Specifically, as shown in fig. 6, the step S500 includes:
step S501, calculating the mean value of each segment of image data, including color data and brightness data;
step S502, sending the calculated mean value data of the color data and the luminance data to an atmosphere lamp corresponding to the image data;
and step S503, controlling the atmosphere lamp to display corresponding color and brightness.
For example, after acquiring each segment of image data, the atmosphere lamp module controls the atmosphere lamp beads at the corresponding positions of each segment of image data to perform display of the same or similar color and brightness. The atmosphere lamp module needs to calculate the average brightness and the average color of each segment of image data, actually, to obtain the brightness and the color of each pixel point in each segment of image data and then average, for example, the resolution of 4K image quality in fig. 3 is 4096 × 2160, the pixel width is 3 pixels, then one segment of image data contains 512 × 3 or 540 × 3 pixels in total, taking the image data of the upper and lower frames as an example, 1536 pixels in total, to obtain the brightness and the color data of all pixel points and average, and finally obtain the values of brightness c and color d, then the driving control unit in the atmosphere lamp module sends the values of brightness c and color d to the atmosphere lamp bead corresponding to the segment of image data, controls the atmosphere lamp bead to display the color corresponding to brightness c and color d, realizes the control of the atmosphere lamp to display the corresponding color and brightness, and weakens the boundary feeling of television display, the user impression is improved.
In an embodiment of the present invention, based on the above method for adjusting an atmosphere lamp based on a picture, a structural design of an atmosphere lamp module is presented, which specifically includes:
take 4K60Hz ultra high definition video as an example. The 4K60Hz video source is connected to the front HDMI one-to-two chip through an HDMI line, and the one-to-two chip can divide the video source of one path of high-speed HDMI interface into two paths of high-speed HDMI interface outputs or one path of high-speed HDMI interface output and one path of relatively low-speed interface output. The low-speed interface may be a low-speed interface such as LVDS or mipi. Meanwhile, for the scheme, no matter the second output interface is a high-speed HDMI interface or a low-speed LVDS interface, mipi interface or the like, great difference cannot be generated on the control effect of the atmosphere lamp, and the low-frame rate or low-resolution video transmitted based on the low-speed LVDS interface can be correspondingly used for controlling the atmosphere lamp by using an FPGA chip with weak processing capability, so that the hardware cost is effectively reduced, wherein the FPGA is a field programmable gate array and has good real-time processing capability.
In this embodiment, a single high-speed HDMI interface and a single LVDS interface are taken as examples. The HDMI output is connected with the display, the LVDS output is connected with the processor, and the processor can select an FPGA, an ARM and other processors capable of processing LVDS input. The FPGA transmits image data input by the LVDS interface, extracts edge data, averages color data and light and shade data of all points of each partition according to partition parameters to obtain display data of the current area atmosphere lamp, and then outputs the data to a driving chip of the atmosphere lamp through the SPI interface to control the display of the atmosphere lamp.
The following shows a hardware design and a software design based on the above structure design and atmosphere lamp adjusting method, specifically including:
hardware design:
as shown in fig. 7, the circuit design diagram of the atmosphere lamp module for playing 4K60Hz ultra high definition video provided in the embodiment of the present invention specifically includes:
the HDMI input interface is connected with the HDMI conversion chip, one path of HDMI output interface of the HDMI conversion chip is used for normally outputting a display picture to a display, and the other path of HDMI output LVDS of the HDMI conversion chip is output to the FPGA for controlling the adjustment of the atmosphere lamp. The HDMI conversion chip is also externally connected with a control MCU for controlling the work of the switching chip. The FPGA is connected with the LED atmosphere lamp control chip through the SPI interface, is externally connected with a FLASH for storing parameters such as programs, partition information and the like, and is also externally connected with a USB interface for interacting with an upper computer.
In the aspect of Power supply, 1.2V and 3.3V voltages are respectively output to the HDMI switching chip through the Power IC, 1.1V and 3.3V voltages are output to the FPGA, and 3.3V voltages are output to the MCU for Power supply.
Designing software:
the FPGA reads each frame of video picture through LVDS, wherein the resolution of the video picture read through the low-speed LVDS interface is lower than that of the picture output by the HDMI output interface, and therefore computing resources of a processor can be effectively saved. The FPGA divides the image data according to partition parameters stored in the FLASH, and the partition parameters can be sent to the FLASH through a USB interface, wherein the specific setting of the partition is determined by the number of actually arranged atmosphere lamps. And the FPGA controls and prepares the average value of the color data and the brightness data of the image data in each partition, and sends the average value data to the LED atmosphere lamp control chip through an SPI protocol.
Therefore, in the embodiment, the input HDMI is divided into one path of normally displayed HDMI output and one path of LVDS output, so that the requirement for reducing the processing capability of the FPGA is met, and the hardware cost is reduced. On the other hand, the real-time processing capacity of the FPGA is utilized, so that the corresponding time of the atmosphere lamp can be effectively reduced, and the effect of low delay is achieved. The atmosphere lamp adjusting function with low cost and good effect is realized, and more comfortable video impression is brought to users.
Exemplary device
As shown in fig. 8, corresponding to the above-mentioned picture-based ambience lamp adjusting method, an embodiment of the present invention further provides a picture-based ambience lamp adjusting device, which includes:
a video signal stream obtaining module 810, configured to obtain a video signal stream of a currently playing video;
in this embodiment, the atmosphere lamp module controls to acquire a video signal stream of a currently played video, and taking a television as a display device as an example, the video signal stream sent by the television or a set top box or a network television box can be intercepted through an HDMI interface. Furthermore, considering that the subsequent atmosphere lamp needs to change in real time according to the played video, the atmosphere lamp module can process the video signal stream by delaying the played video and utilizing the delay time, so as to reduce the processing pressure of the atmosphere lamp module data and effectively reduce the manufacturing cost of the module. By the steps, the video signal stream of the current playing video is acquired in real time.
A frame video image obtaining module 820, configured to obtain a frame video image of each frame based on the video signal stream;
in the embodiment, the ambience light module acquires a frame video image of each frame after acquiring the video signal stream, for example, the frame rate of the display device in the prior art is typically 60 frames, 90 frames or 120 frames. The ambience light module needs to acquire 60, 90 and 120 frames of video images for processing within one second. Further in view of the processing capabilities of the atmosphere light module, the user or manufacturer may set a frame image acquisition rate of less than 60 frames per second to further control the manufacturing cost of the atmosphere light module.

in this embodiment, the ambience light module captures image data of an edge of the frame video image according to the acquired frame video image, that is, data of an outermost circle of image within a display range, where an amount of captured data varies with a pixel width of the captured image edge. By the step, the image data of the frame video image edge for controlling the atmosphere lamp parameters is obtained.
An image data partitioning module 840, configured to partition the image data to obtain multiple segments of image data;
in this embodiment, the atmosphere lamp module divides the acquired image data into partitions to obtain a plurality of segments of image data, the dividing method includes equally dividing along the edge of the image, the number of the partitions is determined according to the number of the beads of the atmosphere lamp, and when the atmosphere lamp is an integral luminescent material such as an OLED, the number of the partitions needs to be manually adjusted by a user. The acquired image data are divided into multiple sections of image data corresponding to the atmosphere lamp beads through the step, so that each lamp bead of the atmosphere lamp corresponds to each section of image data one to one, the matching discomfort between the atmosphere lamp and the display equipment is reduced, and the user experience is improved.
And the atmosphere lamp control module 850 is configured to control an atmosphere lamp corresponding to each segment of image data to perform lamp light adjustment based on the segmented and divided segments of image data.
In this embodiment, the ambience lamp module controls the ambience lamps corresponding to each segment of image data to perform lamp light adjustment according to the multiple segments of image data obtained by partitioning, for example, when a certain segment of image data is color a and brightness b, the ambience lamps on the edge of the segment of image are correspondingly made to display light with color a and brightness b. Further, since the thicknesses of the frames of the display devices are different, for example, if there is a super-narrow frame television and a television with a less-narrow frame, the brightness of the light required to weaken the boundary sense of the super-narrow frame television is less than that of the television with a less-narrow frame, and an adjustment interface is provided for the user to adjust the brightness and color shift of the whole atmosphere lamp. Further, when the user feels that the colors displayed by the light and the colors of the edge of the picture are shifted integrally when the actual display device plays, for example, the colors displayed by the light are 90 degrees before the colors of the edge image, the adjustment can also be performed by the function of the shift. The method realizes that the color of the edge of the currently played video image is sent to the corresponding atmosphere lamp for displaying in real time, eliminates the picture boundary sense and brings better display effect for users.

Compared with the prior art, the atmosphere lamp is arranged on the frame of the display device in advance, when a user uses the display device, the atmosphere lamp carries out light effect display with the same effect according to the display color and the brightness of the frame of the picture, the effect of weakening the boundary sense of the display device is achieved, more immersive use experience is provided for the user, and along with the increase of the number of the atmosphere lamps, the reduction of the size and the reduction of the distance, the sense of incongruity of the atmosphere lamp can be further eliminated, and the boundary sense of the display device is naturally weakened.
