Description

Ambient lighting equipment and its corner color selection methods and corresponding devices and media

Technical field

The present application relates to the field of lighting control, and in particular to an ambient lighting device and its corner color picking method and corresponding devices and media.

Background technique

As a type of smart lighting, ambient lighting equipment can play a role in decorating indoor spaces and displaying information. With the improvement of people's economic level, ambient lighting equipment is becoming more and more popular. One of the functions of the ambient lighting equipment is to generate a lighting effect that echoes the light effect of the specified environment, thereby enhancing the environmental atmosphere.

An example of an ambient lighting device is to set a light strip around the monitor and select colors based on the interface image displayed in the graphical user interface of the monitor. Usually, the border area close to the outer edge of the desktop is selected in the interface image. The color value of the image at each outer edge is obtained. Based on these color values, the luminous color value of each lamp bead corresponding to the four sides of the display is determined, and each lamp bead is controlled to play the corresponding lighting effect. Thus, between the displays On the outer lamp beads, the light atmosphere of the boundary area of the interface image is simulated, thereby extending the light effect of the boundary area of the interface image into the physical space, allowing users to perceive the light atmosphere of the interface image in a wider range, creating a more Immersive usage environment, especially suitable for users to watch videos or play games.

When selecting the color of the interface image, the conventional color selection method is to select the color of the interface image by partitioning, and use the average color value of the pixels in each area after partitioning as the luminous color value of the corresponding lamp bead, where the pixels at the corners of the image are The same partition image requires two side lamp beads to determine the luminous color value. This method cannot adapt to the characteristics of the color distribution of the image, and the light effect played based on this is not delicate enough. Specifically, according to the characteristics of image production, as shown in Figure 1, the main color content of the image is usually concentrated in the middle of the image, as shown in the circle range in the figure, and to a certain extent, the outward radiation is weakened. When the pixels in the corner area are used to determine the luminous color values of the lamp beads on both sides, on the one hand, they will be interfered by the color of the centripetal part of the corner area, making it difficult to accurately correspond to the border color. On the other hand, the corners cannot be The lamp beads on the two sides show different colors.

In summary, it can be seen that in the existing color selection scheme of ambient lighting equipment, when selecting colors for the corners of the image and playing the corresponding lighting effects, the color selection is rough and inaccurate, resulting in the corresponding lighting atmosphere being stiff, and further work is needed. optimization.

Detailed ways

Please refer to Figure 2. It can be seen from the structural schematic diagram of an ambient light device provided by an embodiment of the present application that the ambient light device includes a controller 1, an ambient light 2, and an image acquisition interface. The ambient light 2 and the control The controller 1 is electrically connected in order to accept the control of the computer program running in the controller 1 and work together to realize the lighting effect playback.

The controller 1 of the ambient light equipment is used to control the work of the entire ambient light equipment and is responsible for communication inside and outside the entire ambient light equipment. Among them, the controller 1 is also responsible for driving the image acquisition interface and collecting frame by frame through the image acquisition interface. The environment reference image can be the interface image of the terminal device, and then the lighting effect playback instructions of the corresponding frame are generated according to each frame of the environment reference image, and the ambient light 2 is controlled to play the lighting effect of the corresponding frame through the light effect playback instructions.

The controller 1 usually includes a control chip, communication components, and bus connectors. In some embodiments, the controller 1 can also be configured with a power adapter, a control panel, a display screen, etc. as needed.

The power adapter is mainly used to convert mains power into direct current to power the entire ambient lighting device. The control chip can be implemented using various embedded chips, such as Bluetooth SoC (System on Chip, system-on-chip), WiFi SoC, MCU (Micro Controller Unit, microcontroller), DSP (Digital Signal Processing, digital signal processing), etc. A type of chip, the control chip usually includes a central processing unit and a memory. The memory and the central processing unit are used to store and execute program instructions respectively to achieve corresponding functions. The above types of control chips can come with their own communication components, or additional communication components can be configured as needed. The communication component can be used to communicate with external devices, for example, it can communicate with terminal devices such as personal computers or various smart phones, so that after the user issues various configuration instructions through his terminal device, the control chip of the controller 1 can communicate through The component receives configuration instructions and completes basic configuration in order to control the ambient light operation. In addition, the controller 1 can also obtain the interface image of the terminal device through the communication component, or obtain the real-time preview image collected by the camera. The bus connector is mainly used to connect the power supply to the ambient light 2 connected to the bus and provide lighting effect playback instructions. Therefore, it provides pins corresponding to the power bus and the signal bus. Therefore, when the ambient light 2 needs to be connected to the controller 1 , just connect it to the bus connector through the corresponding connector of the ambient light. The control panel usually provides one or more buttons for implementing switch control on the controller 1, selecting various preset lighting effect control methods, and so on. The display screen can be used to display various control information in order to cooperate with the buttons in the control panel to support the realization of human-computer interaction functions. In some embodiments, the control panel and the display screen may be integrated into the same touch display screen.

Please refer to Figure 3. The ambient lights in Figure 3 can be arranged around the display of the terminal device to form a frame light. The frame light can be surrounded by a single or multiple light strips connected to the bus. As for the light-emitting light strips used in the frame lights and the light-emitting units in the light-emitting light strips, they can be arranged at equal intervals to facilitate grouping the light-emitting units at equal intervals or in equal amounts.

Each light-emitting lamp strip 21 can be composed of multiple lamp beads 210 used as light-emitting units connected in series. Each lamp bead 210 in the same light-emitting lamp strip 21 transmits operating current through the same set of cables connected to the bus. The same light-emitting lamp strip The various lamp beads 210 of 21 can be connected in parallel in terms of electrical connection. When laid out as a frame lamp, although all the lamp beads are arranged around the periphery of the display, it can be regarded as a display frame 4 based on the lamp bead matrix structure as a whole, but the position inside the frame of the display frame 4 No lamp beads are provided, only lamp beads are provided on the four sides. When the light effect is played, a certain light atmosphere effect can be scattered inside and outside the display frame 4.

Each lamp bead 210 of the light strip 21 of the ambient lamp 2 is also provided with a corresponding control chip. The control chip can be selected as disclosed above, or other more economical control chips can be selected. Its main function is to The light-emitting color value corresponding to the lamp bead 210 can be extracted from the light effect playback instruction, and the light-emitting elements in the lamp bead 210 can be controlled to emit corresponding colored light. In some embodiments, the light-emitting elements can be LEDs corresponding to the three primary colors. lamp.

The image acquisition interface can be either a hardware interface or a software interface implemented in the controller 1 . When it is a hardware interface, the image acquisition interface can be implemented as a camera, and the controller 1 loads the corresponding driver to drive the camera to work. When the camera is pointed at the target environment object, such as the display desktop of the terminal device, according to a certain frame By collecting images at a high rate, each frame of interface image can be continuously collected. When it is a software interface, the image acquisition interface can be an image acquisition program implemented on the controller 1 side with the help of the graphics infrastructure technology provided by the operating system of the terminal device. The controller 1 uses various cables such as HDMI, Type-C When the cable is connected to the terminal device, the interface image of the terminal device can be continuously obtained with the support of the graphics infrastructure technology; of course, if the controller 1 and the terminal device have pre-established a wireless projection protocol, the controller 1 can also Through wireless communication, the interface image transmitted by the terminal device is obtained. The graphics infrastructure technology of the operating system varies depending on the type of operating system. For example, the Windows operating system provides the corresponding technology, namely: Microsoft DirectX Graphics Infrastructure, or DXGI for short, to realize this function.

When the ambient light device of the present application is powered on, the control chip of the controller can call and execute a computer program from the memory. Through the default initialization process of the computer program, the ambient light is powered on and initialized, thereby completing the control of the ambient light and the ambient light. Driver configuration for other hardware devices.

In one embodiment, when starting the ambient light, the controller may first send a self-test instruction to the ambient light, and drive each lamp bead in each light strip of the ambient light to return its position information in the light strip. Each lamp bead is equipped with a corresponding control chip for data communication with the control chip in the controller. Therefore, the characteristic information of the lamp bead itself and the characteristic information of other lamp beads can be connected in sequence according to the serial communication protocol. , to realize the representation of its own position information. The serial communication protocol executed between the controller and the lamp bead can be IIC (Inter-Integrated Circuit, integrated circuit bus), SPI (serial peripheral interface, serial peripheral interface), UART (Universal AsynchronousReceiver-Transmitter, universal asynchronous transceiver). After the controller obtains the result data returned by the self-test of each lamp bead from the bus, it analyzes it and determines the display of each lamp bead in the entire ambient light according to the sorting of the characteristic information of each lamp bead in the result data. Position in frame 4, each lamp bead can be regarded as a light-emitting unit, which can be understood as a basic pixel. When constructing the lighting effect playback instruction, the subsequent controller can use the position information of each lamp bead according to actual needs. Sets each base pixel's corresponding glow color value.

After the controller completes the initialization, it can continuously obtain the environment reference image as the target image through the image acquisition interface, and select the color of the target image to determine the luminous color value of each light-emitting unit in the display frame presented by the ambient light. To this end, the display frame of the ambient light can be divided into multiple unit frames, and the target picture can be divided into multiple color-picking images, so that the color-picking images correspond to the unit frames one-to-one, and the corresponding color is determined based on the main color of each color-picking image. the color value, and then generate the luminous color value of each light-emitting unit in the unit frame corresponding to the color image based on the color value.

Accordingly, in one embodiment, the ambient light device can preset layout configuration information corresponding to the ambient light. The layout configuration information is used to describe how to partition the display frame presented by the ambient light into a corresponding frame partition layout. In the layout configuration information, the granularity of plane subdivision of the entire display frame 4 can be specified in any representation form, so that the entire display frame 4 can be divided into multiple unit frames 40 according to the constraints of the layout configuration information. Generally, as shown in FIG. 3 , each unit frame 40 can be covered across multiple lamp beads through division. The setting of the granularity of dividing the display frame 4 in the layout configuration information can be flexibly implemented. For example, the unit frame 40 can be divided according to nine-square grid, sixteen-square grid, etc. in the layout configuration information. Correspondingly, it can be expressed as a unit frame. The total number, such as 9, 16 and other values, so that according to the set value and the total number of all lamp beads in the ambient light, the entire display frame 4 can be divided into unit frames 40; each unit frame can also be specified in the layout configuration information The number of lamp beads spanned, etc., is then divided equally into each lamp bead in the light-emitting lamp strip according to the number; the total number of unit frames 40 that need to be generated can also be set only in the layout configuration information. The list goes on and on, as long as the frame partition layout can be established.

The layout configuration information can be set through the human-computer interaction function implemented on the controller, or it can be set and transmitted to the controller through a terminal device that establishes a data communication connection with the controller, and the controller stores it in its control chip The memory is called on demand.

Considering that the luminescent light strips of the ambient light can be flexibly configured to increase or decrease as needed, in one embodiment, the controller can first detect the total number of lamp beads of the entire ambient light, and by detecting the total number of lamp beads n, according to the layout configuration information The set value, such as the value 10, is understood as dividing every n/10 lamp beads into a lamp group, and using this lamp group to correspond to the unit frame to which the lamp bead belongs. Naturally, for those in For the unit frame corresponding to the corner position in the display frame, it corresponds to the light groups corresponding to its two outer sides at the corner position. Dividing the display frame in this way is not only efficient and fast, but also can adapt to changes in the number of luminous strips and lamp beads, flexibly adjust the pixel density of each unit frame, and enable the controller to increase the number of luminous strips in the ambient light. It reduces the ability to adaptively set the pixel density of the unit frame, keeping the lighting effect playback logic unchanged, ensuring that even after adding or removing luminous light strips, the ambient light lighting effects can still be played normally.

Of course, the layout configuration information can also be defined in other ways, for example, it is set according to the partitioning rules for the environment reference image as the target picture. In short, the rules for partitioning the display frame of the ambient light are usually the same as those for partitioning the target picture. The rules are consistent to ensure that each color image determined after partitioning in the target picture has a unit frame corresponding to it in the ambient light, so that the light-emitting unit of any light group existing in each unit frame can be corresponding from its corresponding The color is picked from the color picked image to realize the light effect projection, so as to project the light atmosphere effect matching the target picture on the entire display frame of the ambient light.

According to the product structure and working principle of the above ambient light equipment, the corner color selection method of the ambient light equipment in this application can be implemented as a computer program product, which is stored in the memory of the control chip in the controller of the ambient light equipment, and is controlled by the control chip. The central processor is called from the memory and then runs. At runtime, it controls the ambient light to play the corresponding light effect according to the environment reference image collected by the image acquisition interface.

Please refer to Figure 4. In one embodiment, the corner color selection method of the ambient light device of the present application is mainly implemented on the controller side of the ambient light device, and is executed by the control chip of the controller, including:

Step S5100: According to the layout configuration information used to represent the frame partition layout, the target picture is divided into regions according to the frame partition layout, and multiple color images distributed around the outer edges of each original image of the target picture are obtained;

When it is necessary to select colors for each lamp bead in the ambient lighting device of the present application based on a target image, the preset layout configuration information can be called from the memory of the controller first. As mentioned above, the layout configuration information is mainly used to represent the frame partition layout corresponding to the lighting effect. The frame referred to here means that when the luminous light strip of the ambient lighting device of the present application is placed around the display of the terminal device, a rectangular frame is formed. This rectangular frame is equivalent to a display frame as a whole. Although the light-emitting unit on the edge of the rectangular frame can emit light to present an effect similar to that of the entire frame, in fact, the ambient lighting device of the present application only emits light from the light-emitting unit on the edge of the rectangular frame. Therefore, the display frame here is actually just a name given for the convenience of understanding.

Referring to the methods disclosed in the various embodiments mentioned above, it can be seen that the layout configuration information can indicate how to partition a plane based on such a display frame. Therefore, the atmosphere lights in the atmosphere lighting device can be configured according to the layout configuration information. That is, all the light-emitting units in the ambient light device are partitioned to obtain multiple unit frames. The target picture can also be partitioned according to the layout configuration information to obtain multiple color-taking areas. Each color-taking area obtains a regional image, so that each color-taking area can obtain a regional image. Each unit frame can establish a corresponding relationship with a regional image.

In this step, the target image is first divided into regions according to the layout configuration information. For example, when the layout configuration information specifies that it is cut according to a 3*4 layout, the target image can be divided into 3 rows and 4 columns, thus obtaining There are 12 color-picking areas, and the image content of each color-picking area is the corresponding area image, as shown in Figure 5.

Since the ambient lighting device of this application is mainly used to expand the light color effect at the boundary of the target picture, it is not necessary to pay attention to the color of the image content in the central part of the target picture, but use the target picture as the original picture and focus on the surrounding target picture. Therefore, this application uses the area images distributed around the four outer edges of the original image as the color picking image. For example, in the above-mentioned case of obtaining 12 area images, In fact, the number of color-picking images is 10, and area images that do not fall outside any of the original images are not considered here.

Step S5200: According to the layout configuration information, the plurality of light-emitting units in the ambient light device are grouped according to the frame partition layout, and corresponding settings are independently set for the outer edges of each original image obtained by dividing each color image. lamp set;

As mentioned above, the layout configuration information can be used to determine each unit frame in the display frame of the ambient light. However, since the ambient light of the present application is actually a plurality of light-emitting units linearly surrounding the display of the terminal device. Yes, in this case, it is actually only necessary to group all the light-emitting units of the ambient light into corresponding unit frames located at corresponding positions on the outer edge of any original image. For example, it is known that the total number of all light-emitting units in the ambient light is 120, and 10 corresponding color-taking images are determined. Therefore, the number of light-emitting units corresponding to each color-taking image is 120/10=12. Accordingly, every 12 adjacent light-emitting units on the light-emitting light strip of the ambient light are divided into the same light group, and the outer edge of the original image obtained by segmentation in the color image corresponding to the unit frame to which each light group belongs is Establish corresponding mapping relationships to facilitate subsequent calls. The outer edge of the original image referred to in this application is determined based on the target image as the original image. Therefore, the so-called outer edge of the original image on the color image actually refers to the color image after segmentation based on the target image. When the color image is mapped to the target image, it belongs to the corresponding edge on the outside.

Based on this, it is not difficult to understand that each of the four unit frames located at the four corners of the entire display frame corresponds to two right-angled outer edges of the original image, and there are also two corresponding light groups. , that is to say, each of the four color-picked images located at the four corners of the target image has two original image outer edges obtained by segmentation. Among the two original image outer edges Each one has its corresponding light set.

Each color-picking image located at the non-corner position of the target picture corresponds to the unit frame at the non-corner position in the display frame. Each unit frame only covers one corresponding light group. Therefore, each unit frame at the non-corner position is A color-picked image has only one outer edge of the original image, corresponding to only one light group.

It can be seen from this that no matter whether the color image is at a corner position or a non-corner position of the target picture, the outer edge of the original image obtained by color image segmentation can be taken to determine the mapping relationship between it and each light group. , specifically, through the correspondence between the color image and the unit frame, the lamp group covered by the unit frame corresponding to the color image is used as the lamp group mapped to the color image, and each segmentation obtained by the color image is The outer edge of each original image is taken as a unit, and the corresponding relationship between the outer edge of each original image and the light group is established, so that each outer edge of the original image obtained by segmentation in each color image has an independent The set lamp group. When this lamp group is actually used, it is laid on one side of the unit frame corresponding to the color pick-up image. This edge also corresponds to the outer edge of an original image obtained by dividing the color pick-up image. .

Step S5300: Use the color-picking image located at any target corner position of the target image as an exception color-picking image, and set the color-picking image based on the partial image covering the outer edge of any original image segmented by the exceptional color-picking image. The luminous color value of the light-emitting unit in the light group corresponding to the outer edge of any original image.

The process of generating corresponding light-emitting color values for the light-emitting units of each light group in the ambient light involves generating settings for the light-emitting color values of the light groups located at the corners of the display frame. For this purpose, description will be made based on an arbitrary target corner position of the target picture corresponding to the display frame.

For the color-picking image located at any target corner position of the target image, it can be used as an exception color-picking image. This exceptional color-picking image has two divided outer edges of the original image. Since each outer edge of the original image Each side has a corresponding light group independently, so the outer sides of the two original images correspond to two light groups.

According to the characteristics of image production, the image color in the center of the target image will interfere with the corner color picking. Therefore, when determining the luminous color value for the light group corresponding to the exceptional color picking image, these interferences can be minimized. Specifically, for any outer edge of the original image in the exceptional color pick-up image, when it is necessary to determine the luminous color value of the corresponding lamp group, an edge covering the outer edge of the original image can be determined on the exceptional color pick-up image. The partial image of the partial image is constrained to cover the outer edge of the original image, that is, the row of pixels where the outer edge of the original image is located. Therefore, the image content of the partial image must be the outer edge of the original image. image content, so as to avoid the partial image containing the image content at the diagonal corners of the target image, thereby avoiding the interference of colors close to the center of the target image, so that the partial image can focus on reflecting the outside of the original image as much as possible Color around the sides.

When the partial images corresponding to the outer edges of the two original images obtained by segmentation on the exceptional color pick-up image are determined in the above manner, it is not difficult to understand that since the outer edges of the two original images are relative to each other at the corner position, it is not difficult to understand. Two vertical outer edges, so in fact, there must be a part of the overlapping image between the two partial images, and this overlapping image is exactly concentrated at the corner position. At the same time, the two partial images have different image contents between each other, and the different image contents are close to each other's outer edges of the original image. Therefore, each partial image can not only avoid the interference of the noisy image content, but also It can subdivide the image content corresponding to the outer edges of the two original images. In this way, when these two partial images are used to generate the luminous color value of the corresponding light group, the two luminous color values are usually different and can better reflect the actual color around the outer edge of the corresponding original image.

After determining the partial images corresponding to the outer edges of each original image, the color values of the pixels in each partial image can be fused into a comprehensive color value, and the comprehensive color value can be set to the corresponding light group. According to the luminous color value of the light-emitting unit, each light-emitting unit in the lamp group is controlled to emit light, so that the color can be basically consistent with the color of the corresponding part of the target picture, and the target picture can be displayed at the corresponding part. The effect of extending the light effect to the outside of the display is equivalent to extending the display boundary of the interface image corresponding to the target image on the display through the ambient light in a physical space, thereby rendering a more immersive lighting atmosphere.

According to the above embodiments, this application first performs area segmentation on the target picture according to the layout configuration information indicating the frame partition layout, and obtains each color image distributed around the outer edges of each original image on the target picture, and then, based on the layout Configuration information, group multiple light-emitting units in the ambient light device to obtain multiple light groups, and then, based on the corresponding relationship between the outer edge of the original image and the color image, divide the original image according to each color image. On the side, establish a corresponding relationship with the corresponding lamp group. This lamp group can be a light-emitting unit that is a lamp bead set surrounding the outer segment of the original image corresponding to the color image on the frame of the lighting effect. In this way , for the color-picking image located at the corner of the target image, treat it as an exceptional color-picking image. Since it corresponds to the two outer edges of the original image, it can be used to determine the outer edges of the two original images. The luminous color value of the light-emitting unit in the corresponding light group in the original image is determined. When determining the luminous color value of the light-emitting unit in the corresponding light group on the outside of an original image, the color image is selected according to the exception, covering the outside of the original image. The partial images of the edge are used to determine the luminous color value of the corresponding lamp group. Therefore, the luminous color values of the two lamp groups corresponding to the corner positions can be different from each other, and the local images of each other are in fact This eliminates the interference of the image content of the far-end centripetal part, so that the corresponding luminous color values of the two lamp groups can present different colors more delicately, and can better reflect the original image corresponding to each lamp group. The real tone at the side, thus, when determining the luminous color value of the light group corresponding to the corner position of the target picture, it is more accurate and delicate, which can make the lighting effect played by the ambient lighting device closer to the reality of the target picture Effect, creating a more immersive lighting atmosphere.

Based on any embodiment of the method of this application, please refer to Figure 6. According to the layout configuration information used to represent the frame partition layout, before the target picture is divided into regions according to the frame partition layout, it includes:

Step S4100: Obtain the interface image of the terminal device;

The controller in the ambient light device can continuously collect the interface image in the external terminal device as an environmental reference image through its image acquisition interface. It is usually collected at a preset frame rate, such as 30 frames per second. For this purpose, the controller The control chip actually needs to process the image stream formed by each frame of interface image, and generate corresponding lighting effects for each frame of interface image in the image stream.

When the image acquisition interface is a software interface, a higher-definition interface image can be obtained directly; when the image acquisition interface is a hardware interface such as a camera, the corresponding interface image can also be obtained, which can achieve the same effect as the software interface. It can be flexibly adapted in practice.

Step S4200: Identify the edge black band located on the outer edge of the interface image;

Since the frame of the video or game program interface played on the terminal device may not match the display frame of the monitor, the interface image obtained by the controller may contain edge black bands. In this case, the interface image can be preprocessed, and the coordinate information of the edge black belt can be determined by calculating the connected domains of black pixels located on the edge areas of each outer edge of the interface image. The coordinate information of each edge black band can be expressed as a window coordinate.

Step S4300: Crop and remove the edge black band from the interface image to obtain a target picture.

After determining the coordinate information of each edge black band in the interface image, the edge black band is cropped based on the coordinate information, and the corresponding edge black band is cut out to obtain relatively pure image content, which can be used as a target image.

In a further alternative embodiment, considering that the original interface image usually has a higher resolution, but there is no need to rely on high-resolution data when actually playing the lighting effect, the interface image can be modified on the basis of removing the edge black band. Perform compression processing and compress it to a preset resolution to obtain an interface image with a smaller data volume and use it as the target image. Accordingly, when this application is actually used, the interface image can be compressed as needed.

In the above embodiment, by first removing the edge black bands from the interface image to obtain the target image, it can be ensured that no black edges will appear on the outer edges of each original image of the target image, thereby not affecting the brightness of the corresponding determined luminous color value, and ensuring The atmosphere effect based on the lighting effects played by the target image.

Based on any embodiment of the method of the present application, please refer to Figure 7. The color-picking image located at any target corner position of the target picture is used as an exception color-picking image, and its segmentation is covered according to the exception color-picking image. For the partial image obtained on the outer edge of any original image, set the luminous color value of the light-emitting unit in the light group corresponding to the outer edge of any original image, including:

Step S5310: Determine the two outer edges of the original image obtained by segmenting the exceptional color-picking image and their corresponding light groups;

For any exceptional color-picked image, since it is located at a corner of the target image, two outer edges of the original image are obtained after segmentation, and the two outer edges of the original image can be determined by comparing the target image. At the same time, since the mapping relationship between the outer edge of the original image and a light group has been established in advance, the corresponding light group data can also be called.

Step S5320: Determine comprehensive color values corresponding to partial images covering the outer edges of the original image for the two outer edges of the original image in the exceptional color-picking image, wherein the two partial images are at the target angle. There are overlapping images at the top position;

As for the two outer edges of the original image of the exceptional color pick-up image, it has been revealed in the previous article that each outer edge of the original image can determine its corresponding partial image from the exceptional color pick-up image, and then, based on this partial image The color values of pixels in the image can be fused to obtain a comprehensive color value. Just determine the corresponding comprehensive color value for the outer edges of the two original images based on their respective partial images. The comprehensive color value can be determined by averaging the color values of all pixels in the local image, or by using a preset algorithm to weight the color values of these pixels. In some embodiments, before determining the comprehensive color value corresponding to the partial image in the above manner, the dark light pixels in the partial image can also be filtered according to a preset dark light threshold, and only retain the color values higher than the dark light threshold. of valid pixels are used to determine the combined color value.

As analyzed above, since the two partial images are determined based on the outer edges of their respective original images, the two partial images must have a partially overlapping image at the corner position. This overlapping image makes the two comprehensive color values All reflect the weighted characteristics of the image content at the corner point. At the same time, since the image content of the two partial images outside the corner point is its own exclusive image content, there is a certain difference between the two comprehensive color values due to the superposition of the color values of their respective exclusive image content. The difference is that when this exception color selection image is used to set color values for the light-emitting units in the light groups corresponding to the two outer edges of the original image, the light emitted by the two light groups will appear more delicate.

Step S5330: Set the comprehensive color value corresponding to the outer edge of each original image to the luminous color value of the lamp group corresponding to the outer edge of the original image.

After the comprehensive color value corresponding to the outer edge of each original image of each exception color-picking image is determined, each comprehensive color value can be set to the light group mapped by its corresponding outer edge of the original image. The light-emitting color values of each light-emitting unit are transmitted to each corresponding light-emitting unit along with the packaging and transmission of the lighting effect playback instructions. Each light-emitting unit controls the light-emitting elements in the light-emitting unit to emit light according to the corresponding light-emitting color value.

According to the above implementation, it can be seen that when picking the color for the lamp group corresponding to the exceptional color picking image at the corner position, considering that this exceptional color picking image is located on the outer edges of the two original images at the corner position, the corresponding situation also exists For two light groups, a partial image is selected corresponding to the outer edge of each original image. There are both overlapping images and difference images between the two partial images. Therefore, the corresponding light group is determined based on the two partial images. When emitting color values and playing light effects, the light effects of the two light groups can not only inherit the same color characteristics of the corner positions, but also integrate the effects of the image colors of their own unique parts, making the lighting effects of the corner positions more beautiful. Delicate and soft, it more accurately reflects the image color effect at the corners.

Based on any embodiment of the method of the present application, please refer to Figure 8. In the exceptional color-picking image, the partial images corresponding to the outer edges of the two original images are respectively determined to cover the outer edges of the original image. Comprehensive color values, including:

Step S5321: Divide the exceptional color image into equal segments in both vertical and horizontal directions to obtain multiple graphics elements;

In order to facilitate the standardized processing of the color picking process of the four exceptional color picking images located at the four corners of the target image, a standardized algorithm can be used for unified implementation. In this embodiment, a matrix division method is used to divide each exceptional color image into equal divisions. Specifically, as shown in Figure 9, the exceptional color image at the target corner position can be equally divided in both vertical and horizontal directions, and divided into multiple primitives. For example, in Figure 9, for the upper left corner After the positional exception color-picking image is divided into two halves in both vertical and horizontal directions, a total of 4 graphics elements of 2*2 are obtained. In other embodiments, the exceptional color extraction image can also be divided into three equal parts or even into four equal parts to obtain corresponding multiple graphic elements. The greater the number of divisions, the more refined the image content can be when subsequently determining the partial image, and those skilled in the art can flexibly determine the number of equal divisions according to the principles disclosed herein.

Step S5322: For each outer edge of the original image, determine that each graphic element covering the outer edge of the original image is constructed into a partial image belonging to the same image area;

When determining the partial image corresponding to the outer edge of each original image in the exceptional color-picking image, in this embodiment, among all the equally divided image elements, a row of image elements close to the outer edge of the original image is selected. Constructed into a partial image. As shown in Figure 9, after dividing the exceptional color-picking image into four primitives A, B, C, and D, for the outer edge of the original image located above Figure 9, select the two primitives A and B located above to form the The partial image corresponding to the outer edge of the original image above. For the outer edge of the original image on the left side of Figure 9, two primitives A and C are selected to form a partial image corresponding to the outer edge of the original image on the left. The corners The point position A is the coincident image between the two local images. It can be seen that the partial image as a whole covers the outer edge of its corresponding original image. According to this principle, in the exceptional color-picking image, the partial image corresponding to the outer edge of each original image is actually the image content obtained by taking the outer edge of the original image as the axis and extending each row of pixels to the opposite side.

Based on this, it is not difficult to understand that when the exceptional color picking image is located in the lower left corner of the target image, assuming that it is divided into equal parts and still labeled according to the division layout of the exceptional color picking image in the upper left corner of Figure 9, then the original image at the bottom The partial image corresponding to the outer edge is composed of C and D, and the partial image corresponding to the outer edge of the original image on the left is composed of A and C. C is the overlapping image between the two partial images. In the same way, when the exceptional color image is located in the upper right corner of the target image, the partial image corresponding to the outer edge of the original image above it is composed of A and B, and the partial image corresponding to the outer edge of the original image on the right It consists of B and D. The overlapping image between the two partial images is B; when the exception color image is located in the lower right corner of the target image, the partial image corresponding to the outer edge of the original image below it is composed of C and D. , the partial image corresponding to the outer edge of the original image on the right is composed of B and D, and the overlapping image between the two partial images is D.

It can be seen that according to the above method, the partial image is determined by equal division of the exceptional color image. In fact, the exceptional color image is partitioned in a matrix manner to obtain multiple primitives, and then the corresponding parts of the partial image are determined. Each primitive of the same image area is used to define a local image, in which each local image is regarded as the same image area, which is convenient for description with coordinate information. Processing in this way is more efficient in operation and can ensure that each The size specifications of local images are standardized, which is particularly suitable for implementation on embedded chips. The various control chips used in the controllers of ambient lighting equipment are exactly these embedded chips.

Step S5323: Determine the average value of the color values of all pixels in the same image area as the comprehensive color value of the corresponding local image in the image area.

In order to determine the luminous color value of the light group corresponding to the outer edge of any original image in each exception color image, it is necessary to determine the comprehensive color value of the pixels based on the partial image corresponding to the outer edge of the original image. In this embodiment, for the local image where the comprehensive color value needs to be determined, the color values of all the pixels in the image can be averaged. Specifically, the color values of each primary color may be averaged, so as to obtain the average value corresponding to each primary color. , forming a comprehensive color value. The comprehensive color value represents the average effect of the color values of all pixels in the entire partial image, because this partial image essentially covers the outer edge of the corresponding original image, that is, it extends inward from the outer edge of the original image. of the image area, so the determined comprehensive color value can effectively reflect the overall color effect in this image area.

It is not difficult to understand that the corresponding comprehensive color value of the partial image corresponding to the outer edge of each original image in the exceptional color image can be determined in the manner of this embodiment, so that the original image can be further determined based on the comprehensive color value. The luminous color value of the light-emitting unit in the light group corresponding to the outer edge.

According to the above embodiments, the present application partitions the exceptional color-picked image in a matrix division manner to obtain multiple primitives, and then selects multiple primitives covering the pixels outside the original image to determine the local image, so that the local image can be determined according to the local image. The image determines the comprehensive color value of the corresponding outer edge of the original image. Processing in this way has the advantage of computational efficiency, and can ensure that the corresponding comprehensive color values of the outer edge of each original image of each exception color image are obtained. Determined according to the same standard. Accordingly, when playing the corresponding lighting effect, the light effects obtained at the four corners reproduce the color effects at the corners of the target picture with the same standard, so the overall effect will be more coordinated. harmonious.

Based on any embodiment of the method of the present application, in the exceptional color-picking image, the comprehensive color values of the local images corresponding to the outer edges of the two original images are determined for the two outer edges of the original image, including :

Step S5321': For each partial image corresponding to the outer edge of the original image, using the outer edge of the original image as the axis, calculate the mean value of the color values of each row of pixels in the partial image that is parallel to the axis. ;

In this embodiment, considering that in the exceptional color pick-up image, the local image corresponding to the outer edge of each original image, the closer the pixels to the outer edge of the original image are, the more likely they are to affect the boundary effect. Therefore, the pixels related to the original image can be examined first. The average color value of each row (row or column) of pixels with parallel edges on the outside of the image to measure the overall color of each row of pixels.

Specifically, it may be necessary to determine the outer edge of the original image of the comprehensive color value as the axis, and then use the rows of pixels parallel to the axis in the exceptional color image as the corresponding set, and compare the colors of each pixel in the set The values are averaged to obtain the corresponding mean. Each row of pixels can get its corresponding mean in the same way.

Step S5322': Perform a weighted sum of the mean values of the color values of each row of pixels in a manner that the weight of the opposite edge decreases toward the outer edge of the original image to obtain a comprehensive color value.

After the above steps, each row of pixels in the local image that is parallel to the corresponding outer edge of the original image will obtain its corresponding mean value. Considering that the color values of pixels closer to the outer edge of the original image have a greater impact on the border color effect In this embodiment, these average values are further weighted and summed to obtain a comprehensive color value, and the weight matched by each average value is based on the row where the average value is located, from the outer edge of the original image toward its opposite The order of the direction of the edges determines the weight corresponding to the mean value of the row, and makes the weights of the mean values of each row decrease from front to back in this order to ensure that the mean value of the row that is sorted earlier has a greater impact on the comprehensive color. The greater the impact of the value, the lower the mean of the ranked row, the smaller the impact on the comprehensive color value.

In one embodiment, the weight matched by the mean value corresponding to each row can take a value between the normalized interval [0,1], and there is a certain descending relationship between the values, and the mean value of all rows is guaranteed to be The sum of the weights is 1.

The comprehensive color value of the local image is determined according to the above embodiment. Since the fact that the pixels closer to the outer edge of the original image have a greater impact on the border color and vice versa, the determined comprehensive color value can better reflect the Exceptionally select the true color effect at the outer edge of the corresponding original image in the color-picking image. When this comprehensive color value is used to play lighting effects, more realistic light can be obtained at the corresponding position of the display frame of the ambient lighting device. Effect.

Based on any embodiment of the method of the present application, according to the layout configuration information, multiple light-emitting units in the ambient light device are grouped according to the frame partition layout, and each color image segmented result is After setting the corresponding light group independently on the outside of each original image, it also includes:

Step S5400: Use the color pickup image located at any non-corner position of the target image as a regular color pickup image, and set the outer edge of the original image obtained by segmenting the regular color pickup image based on the entire image of the regular color pickup image. The luminous color value of the light-emitting unit in the corresponding light group.

For other color-picking images located at non-corner positions of the target image, since there is only one outer edge of the segmented original image, they are distinguished from the exceptional color-picking images and are named regular color-picking images. For conventional color-picking images, it is only necessary to determine the comprehensive color value for a single lamp group corresponding to the outer edge of a single original image, and then determine the luminous color value of the light-emitting unit in the lamp group based on this comprehensive color value.

When determining the comprehensive color value of the outer edge of the original image based on the conventional color picking image, it can be determined in combination with any of the multiple methods disclosed previously in this application, for example:

In one embodiment, the average value can be calculated based on the color values of all pixels corresponding to the entire conventional color image, and the average value can be used as a comprehensive color value to determine the luminous color value of the light-emitting unit in the corresponding lamp group.

In another embodiment, the weighted summation of the mean matching weights of the color values of each row of pixels parallel to the outer edge of the original image can be performed as disclosed above, so that the weights matched by each mean value are adjusted from the outside to the inside. There is a relationship of decreasing weight, and the sum of the weights of all the average values is 1, which reflects that the closer the color value of the pixels to the outer edge of the original image is, the higher the weight is obtained, so that the corresponding luminous color value can also be determined. .

In an embodiment that weighs the comprehensive effects of the exceptional color-picking image and the regular color-picking image, the same algorithm is used for both the exceptional color-picking image and the regular color-picking image to determine their respective comprehensive color values. Specifically, the above-mentioned method may be used. The disclosed method is implemented by performing a weighted summation of the mean matching weights of the color values of each row of pixels. All the comprehensive color values determined thereby control the light-emitting units in the light groups at the corresponding unit frames to play light effects. The overall effect is more coordinated and softer, and the light transition effect between the various light groups on the four sides of the display is also more natural.

It can be seen that when the comprehensive color value is determined based on the conventional color image, since the conventional color image only has one outer edge of the original image obtained by segmentation, no complicated processing is required, and only a simple average is needed based on the color values of each pixel in the entire image. Or weighted average, the corresponding comprehensive color value can be obtained. The calculation amount is small and the operation is fast. Multiple conventional color images can be processed in parallel and at high speed with the help of the same type of threads, which is especially suitable for embedded chip processing.

Based on any embodiment of the method of this application, please refer to Figure 10. The color pickup image located at any non-corner position of the target picture is regarded as a regular color pickup image. According to all images of the conventional color pickup image, Set the luminous color value of the light-emitting unit in the light group corresponding to the outer edge of the original image obtained by segmenting the conventional color-picking image, including:

Step S5410: Based on the entire image of the conventional color-picking image, filter the dark-light pixel set therein to obtain an effective pixel set;

In the main image content of the target picture, sometimes there are a large number of black pixels due to the presence of some black objects. When these black pixels are concentrated in a conventional color image, if the image content of the conventional color image is directly determined Comprehensive color values are then used to determine the luminous color value of the light-emitting unit in the light group, which may cause the light effect to be too dim when playing the light effect and fail to achieve the expected effect. In this case, according to this embodiment, pixel filtering processing can be performed on the conventional color image first.

Specifically, you can first preset a dark-light threshold, and then traverse the entire image of the conventional color-picking image. Mark the pixels with color values lower than the dark-light threshold as dark-light pixels, and mark the pixels with color values exceeding the dark-light threshold as dark-light pixels. The pixels are marked as valid pixels, and the dark light pixel set and the valid pixel set are obtained respectively. The dark light threshold is used to measure whether the color value of a pixel reaches the expected corresponding empirical threshold. For example, for the color values represented by the three primary colors of red, green, and blue, the dark light threshold corresponding to the three primary colors can be set to RGB ( 10, 10, 10), when the color value of a pixel has a primary color value lower than the color value of the corresponding primary color in the dark light threshold, it can be determined as a dark light pixel, otherwise it is a valid pixel. Of course, the judgment conditions can also be flexibly modified. For example, it can be set to determine the pixel only when the color values of two or more primary colors are lower than the color values of the corresponding primary colors in the holiday dark light threshold. It is a dark pixel, otherwise it is a valid pixel.

It can be seen that through the above process, the pixels in the conventional color-picking image that will cause dim lighting effects are effectively identified. After excluding them, the effective pixels can be obtained. The data set composed of effective pixels is the effective pixel set.

Step S5420: Calculate the mean value of the color values of all effective pixels based on the effective pixel set;

On the basis of the effective pixel set, in order to simplify the operation and improve the operation efficiency, the color values of all effective pixels can be directly averaged by simple arithmetic to obtain the corresponding average value. Of course, it can also be replaced by other implementations disclosed above, such as the method disclosed above of performing weighted summation of matching weights on each row of pixels to determine the comprehensive color value.

Step S5430: Set the average value to the luminous color value of the light-emitting unit in the light group corresponding to the outer edge of the original image obtained by segmenting the conventional color image.

The mean value determined based on the effective pixel set of the conventional color-picking image is used as the comprehensive color value. Therefore, it can be used as the luminous color value of the light-emitting unit in the light group corresponding to the outer edge of the original image obtained by segmenting the conventional color-picking image. .

It can be seen from the above embodiments that in this application, when using a conventional color-picking image to determine the luminous color value of the corresponding lamp group, the dark pixels in the image are first removed, and after the effective pixels are left, the color values of the effective pixels are then used. To determine the luminous color value, avoid black objects in the image content from lowering the brightness of the light, and ensure that the light effect is brighter and more colorful.

Based on any embodiment of the method of this application, when using the comprehensive color value to determine the luminous color value of the light-emitting unit in the corresponding lamp group, there can also be many ways. For example, the comprehensive color value can be directly used as the corresponding The luminous color value of each light-emitting unit can be directly assigned. You can also set the luminous color value of the luminous unit in the center of the light group to the comprehensive color value based on the corresponding comprehensive color value of the lamp group. As for the luminous color value of the center The luminous color value of the light-emitting units on both sides of the unit can be adjusted by using the comprehensive color value corresponding to the adjacent lamp group on the corresponding side to obtain the luminous color value of each light-emitting unit on the corresponding side, so that the current The light color of the central light-emitting unit of the lamp group is the color represented by the comprehensive color value, while the light color of the light-emitting units on both sides gradually transitions to the color represented by the corresponding comprehensive color value of the lamp groups on both sides. In this way, the natural transition effect of light between adjacent light groups can be further improved, making the lighting effects played by the ambient lighting equipment more natural and delicate.
