Description

Ambient lighting control methods and related devices Technical Field

[0001] This application relates to the field of lighting technology, specifically to an ambient light control method and related devices. Background Technology

[0002] Ambient lighting can enhance the viewing experience during movies. Currently, there are many solutions that set the ambient light color by analyzing the colors in the video scene images. However, this still doesn't fully meet the user's viewing experience needs. Further research is needed to determine how to better control ambient lighting to provide a more immersive viewing experience. Summary of the Invention

[0003] This application provides an ambient lighting control method and related device, which can provide users with a more immersive movie-watching experience.

[0004] In a first aspect, this application provides an ambient lighting control method, the method comprising: acquiring an image displayed through a display device; and controlling the presentation effect of ambient lighting in a target space area based on the image displayed on the display device. The presentation effect includes one or more of color, brightness, color temperature, shape effect, and dynamic effect. Wherein, if a first image displayed on the display device includes a first target color, and a second image displayed after the first image includes a second target color, the presentation effect of ambient lighting in a first preset area of ​​the target space area matches the first target color, and the presentation effect of ambient lighting in a second preset area of ​​the target space area matches the second target color, wherein the first target color and the second target color each include one or more colors.

[0005] In the above solution, the ambient lighting in the target space area can be adjusted according to the displayed image over time. For example, a first preset area in the target space area can be controlled to display an ambient lighting effect that matches the image being displayed on the display device, and a second preset area in the target space area can be controlled to display an ambient lighting effect that matches the next image displayed on the display device, thereby providing users with a more immersive viewing experience. For example, the target space area could be a passenger compartment in a vehicle or a space in a movie theater.

[0006] In one possible implementation, the first preset area is closer to the viewer served by the display device than the second preset area.

[0007] For example, the aforementioned target space area is the passenger compartment of the vehicle. If the aforementioned display device is the vehicle's central control screen or the passenger-side screen, and the viewer is located in the driver's seat and / or the passenger seat, the aforementioned first preset area is the front passenger compartment area including the driver's seat and / or the passenger seat, and the aforementioned second preset area is the rear passenger compartment area. Alternatively, for example, if the aforementioned display device is the vehicle's rear display device, and the viewer is located in the rear seats, the aforementioned first preset area is the rear passenger compartment area, and the aforementioned second preset area is the front passenger compartment area including the driver's seat and / or the passenger seat.

[0008] In the above scheme, the first preset area presents an ambient lighting effect that matches the image being displayed on the display device. Being closer to the viewer allows the viewer to be more immersed in the movie.

[0009] In one possible implementation, if the aforementioned first target color includes multiple colors, the ambient lighting effect of the first preset area in the aforementioned target space region matches the aforementioned first target color, including:

[0010] The color of the ambient light in the first preset area of ​​the aforementioned target space region is the average color of the multiple colors included in the aforementioned first target color. Alternatively, the color of the ambient light in the first preset area of ​​the aforementioned target space region includes some or all of the colors included in the aforementioned first target color.

[0011] In one example of the above solutions, the average color of multiple colors in the image can be selected as the ambient light color for the corresponding area. Alternatively, the ambient light can be controlled to display multiple colors included in the image. This creates a more fitting spatial viewing atmosphere and enhances the viewing experience.

[0012] In one possible implementation, when the screen displayed by the aforementioned display device includes a preset feature object, the ambient light in the aforementioned target space area presents a shape effect that matches the shape of the preset feature object. For example, if the preset feature object included in the screen displayed by the aforementioned display device comprises dot-like elements, the ambient light in the aforementioned target space area presents a shape effect including dots. Alternatively, for example, if the preset feature object included in the screen displayed by the aforementioned display device comprises line-like elements, the ambient light in the aforementioned target space area presents a shape effect including lines.

[0013] In the above solution, the ambient light shape effect can be presented according to the shape of the characteristic objects in the displayed screen to better enhance the atmosphere and provide users with a more immersive viewing experience.

[0014] In one possible implementation, if the ambient light in the aforementioned target space area presents a dotted shape effect, the dots presented by the ambient light in the aforementioned target space area are dynamic dots, and the dynamic effect of the dots presented by the ambient light in the aforementioned target space area matches the dynamic state of a preset feature object in the image displayed by the aforementioned display device. The dynamic effect of the dots includes one or more of the following: the direction of movement, the speed of movement, the speed of flashing, and the change in brightness.

[0015] If the ambient lighting in the aforementioned target space area presents a linear shape effect, the lines presented by the ambient lighting in the aforementioned target space area are dynamic lines, and the dynamic effect of the lines presented by the ambient lighting in the aforementioned target space area matches the dynamic state of preset feature objects in the image displayed by the aforementioned display device. The dynamic effect of the lines includes one or more of the following: the direction of movement, the speed of movement, the speed of flashing, and the change in brightness.

[0016] In the above solution, the ambient lighting presents an ambient lighting effect that matches the dynamic situation of preset characteristic objects in the picture, which can make the spatial atmosphere more vivid and meet the user's need for a more immersive movie-watching atmosphere.

[0017] In one possible implementation, if the image displayed in the first display area of ​​the aforementioned display device includes a first type of color, and the image displayed in the second display area of ​​the aforementioned display device includes a second type of color, the ambient light effect of the first sub-area in the aforementioned target space area matches the aforementioned first type of color, and the ambient light effect of the second sub-area in the aforementioned target space area matches the aforementioned second type of color.

[0018] For example, the aforementioned target space area is the passenger compartment of the vehicle, the aforementioned display device is the display device in the aforementioned vehicle, and the aforementioned first display area and the aforementioned second display area are areas within at least two display areas divided in the vertical direction by the aforementioned display device, or the aforementioned first display area and the aforementioned second display area are areas within at least two display areas divided in the horizontal direction by the aforementioned display device. The aforementioned first sub-area is the space area in the aforementioned passenger compartment corresponding to the aforementioned first display area, and the aforementioned second sub-area is the space area in the aforementioned passenger compartment corresponding to the aforementioned second display area.

[0019] In the above solution, when different display areas in the display device display different colors, the corresponding colors can be presented in the corresponding spatial areas to better enhance the atmosphere and provide users with a more immersive viewing experience.

[0020] In one possible implementation, the aforementioned passenger cabin includes a target sub-area, in which viewers are seated, and the aforementioned first sub-area and the aforementioned second sub-area are spatial regions within the aforementioned target sub-area.

[0021] In the above solution, the spatial atmosphere of the first and second sub-areas can be adaptively adjusted according to the area where the viewer is located, making the created spatial atmosphere more intimate to the viewer and allowing for a more immersive viewing experience. Furthermore, areas without viewers can save energy consumption on ambient lighting.

[0022] In one possible implementation, the aforementioned method further includes: acquiring a first audio feature of the audio of the first screen displayed on the aforementioned display device and the position where the audio of the first screen is played. Based on the aforementioned first audio feature, the ambient light corresponding to the position where the audio of the first screen is played is controlled to be presented as a highlight. The aforementioned first audio feature includes one or more of the following: the rhythm point of the audio of the first screen, the rate of change of the aforementioned rhythm point, and the spectral energy of the sound frequency.

[0023] In the above solution, the ambient light at the corresponding position can be controlled to create a highlight effect based on the audio playback location on the screen. Furthermore, the highlight effect can be adjusted according to the characteristics of the audio displayed on the screen, creating an ambient light effect that resonates with the audio and enhances the viewing atmosphere.

[0024] In one possible implementation, the method further includes: acquiring a second audio feature of the audio of the second screen displayed on the display device and the position where the audio of the second screen is played. Based on the second audio feature, the ambient light corresponding to the position where the audio of the second screen is played is controlled to be presented as a highlight. The second audio feature includes one or more of the following: the rhythm point of the audio of the first screen, the playback speed of the rhythm point, and the spectral energy of the sound frequency.

[0025] In the above scheme, the audio playback position can be different for different images displayed on the display device. Therefore, the control device can control the ambient light to present a highlight lighting effect based on the audio playback position corresponding to each displayed image.

[0026] In one possible implementation, the aforementioned first screen includes a screen of multiple frames, and the aforementioned second screen includes a screen of multiple frames.

[0027] In the above solution, since each frame of video image is displayed for a very short time, if each frame corresponds to an ambient lighting effect, the lighting effect may change drastically, reducing the viewing experience. Because adjacent video frames are not significantly different, the granularity of adjusting the lighting can be based on the composition of adjacent frames. This allows for a smooth transition of the ambient lighting effect, improving the user's viewing experience.

[0028] Secondly, this application provides an ambient lighting control device, which includes:

[0029] The acquisition unit is used to acquire the image displayed by the display device.

[0034] Alternatively, if the aforementioned display device is a rear-seat display device of the aforementioned vehicle and the viewer is located in the rear seat of the vehicle, the aforementioned first preset area is the rear passenger compartment area, and the aforementioned second preset area is the front passenger compartment area including the driver's seat and / or the front passenger seat.

[0035] In one possible implementation, if the aforementioned first target color includes multiple colors, the ambient lighting effect of the first preset area in the aforementioned target space region matches the aforementioned first target color, including:

The dynamic effect of the dots includes one or more of the following: the direction of movement, the speed of movement, the speed of flashing, and the change in brightness.

[0041] If the ambient lighting in the aforementioned target space area presents a linear shape effect, the lines presented by the ambient lighting in the aforementioned target space area are dynamic lines, and the dynamic effect of the lines presented by the ambient lighting in the aforementioned target space area matches the dynamic state of preset feature objects in the image displayed by the aforementioned display device. The dynamic effect of the lines includes one or more of the following: the direction of movement, the speed of movement, the speed of flashing, and the change in brightness.

[0042] In one possible implementation, if the image displayed in the first display area of ​​the aforementioned display device includes a first type of color, and the image displayed in the second display area of ​​the aforementioned display device includes a second type of color, the ambient light effect of the first sub-area in the aforementioned target space area matches the aforementioned first type of color, and the ambient light effect of the second sub-area in the aforementioned target space area matches the aforementioned second type of color.

[0043] In one possible implementation, the aforementioned target space area is the passenger compartment of the vehicle, the aforementioned display device is the display device in the aforementioned vehicle, and the aforementioned first display area and the aforementioned second display area are areas of at least two display areas divided in the vertical direction by the aforementioned display device, or the aforementioned first display area and the aforementioned second display area are areas of at least two display areas divided in the horizontal direction by the aforementioned display device.

[0073] The embodiments of this application are described below with reference to the accompanying drawings. The terms "first," "second," "third," and "fourth," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish different objects, not to describe a specific order. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to these processes, methods, products, or devices. The reference to "embodiment" herein means that a specific feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0074] In the various embodiments of this application, on the one hand, they are independent of each other, meaning that the embodiments do not limit or constrain each other. On the other hand, unless otherwise specified or there is a logical conflict, the terminology and / or descriptions in the various embodiments are consistent and can be referenced mutually. Technical features in different embodiments can be combined to form new embodiments based on their inherent logical relationships.

[0075] The embodiments of this application will be described below with reference to the accompanying drawings.

[0076] First, let's introduce an ambient lighting control system that may be applicable to the embodiments of this application. For example, referring to Figure 1, the system may include a control device 101 and an ambient light 102. Exemplarily, the control device 101 can control the presentation effect of the ambient light 102 based on audio and video information. The specific implementation process can be referred to in the subsequent related descriptions, and will not be repeated here. The presentation effect may include, for example, the presented light color, light brightness, light color temperature, light shape effect, and light dynamic effect, etc. Exemplarily, the light shape effect may include various geometric shapes such as dots, lines, rings, and hearts. Exemplarily, the light dynamic effect may include flashing modes, breathing modes, meteor modes, water wave modes, or various custom light dynamic modes, etc.

[0077] For example, in one possible implementation, the ambient lighting control system described above can be deployed in a vehicle. In this implementation, the control device 101 can be, for example, a controller in the vehicle. For instance, the control device 101 can be an intelligent driving computing platform MDC, a vehicle domain controller (VDC), a vehicle control unit (VCU), or an intelligent driving controller, etc., in the vehicle. Alternatively, the control device 101 can be a combination of multiple controllers in the vehicle. Or, the control device 101 can be, for example, a device with processing capabilities deployed in the vehicle, such as an in-vehicle infotainment system or various microcontrollers, etc., which is not limited in this embodiment. Furthermore, the ambient light 102 can be, for example, an ambient light deployed in the vehicle's passenger compartment. Then, the control device 101 can control the presentation effect of the ambient light 102 according to the audio and video played by the vehicle's audio-visual equipment.

[0078] In another possible implementation, for example, the ambient lighting control system described above can be deployed in a movie theater, home theater, or outdoor viewing area, etc., that provides movie viewing services to users. In this implementation, the control device 101 can be, for example, a controller deployed in the movie theater, or a terminal device that can communicate with the ambient lighting. This terminal device can be, for example, a mobile phone, computer, cellular phone, personal digital assistant (PDA) device, or wearable device. This application embodiment does not impose any limitations on this. Therefore, the control device 101 can control the presentation effect of the ambient lighting 102 based on the audio and video played by the audio-visual equipment in the movie theater.

[0079] It is understood that the aforementioned ambient lighting control system is not limited to deployment in the aforementioned vehicles or movie theaters, but can also be deployed in other scenarios where the presentation effect of the ambient lighting 102 needs to be controlled based on audio and video. The embodiments in this application will not be described in detail.

[0080] To provide users with a more immersive viewing experience, this application embodiment provides an ambient lighting control method. Referring to Figure 2, the method may include, but is not limited to, the following steps S201 and S202.

[0081] S201, The control device acquires the screen displayed by the display device.

[0082] For example, the control device may be the control device 101 in the ambient lighting control system shown in FIG1 above.

[0083] For example, the aforementioned display device may be a display screen. Alternatively, the display device may be a combination of a projector and a projection screen, or other devices capable of presenting visual images. For example, if the aforementioned ambient lighting control system is deployed in a vehicle, the aforementioned display device may be a display device in the vehicle. If the aforementioned ambient lighting control system is deployed in other viewing venues, the aforementioned display device may be a display device in that viewing venue. It is understood that the description herein is merely illustrative.

[0084] For example, the control device described above can acquire screen information displayed through the display device. For instance, the control device can acquire a video stream displayed through the display device and parse the video frames in the video stream to obtain screen information of the video frames. The specific implementation process of acquiring screen information is not detailed in this embodiment. For example, the screen information may include information such as the color and brightness of the screen.

[0085] S202. The control device controls the presentation effect of the ambient lighting in the target space area based on the screen displayed on the display device; the presentation effect includes one or more of color, brightness, color temperature, shape effect, and dynamic effect. When the first screen displayed on the display device includes a first target color, and the second screen displayed after the first screen includes a second target color, the presentation effect of the ambient lighting in the first preset area of ​​the target space area matches the first target color, and the presentation effect of the ambient lighting in the second preset area of ​​the target space area matches the second target color. The first target color and the second target color each include one or more colors.

[0086] For example, if the aforementioned ambient lighting control system is deployed in a vehicle, the target space area can be the passenger compartment of the vehicle. That is, the ambient lighting can be ambient lighting deployed in the passenger compartment of the vehicle. For example, the ambient lighting in the passenger compartment can be set in any location such as the top, bottom, or around the seats of the passenger compartment, and this application embodiment does not limit this. Alternatively, if the aforementioned ambient lighting control system is deployed in other movie theaters, the aforementioned target space area can be a space area including the viewing area of ​​the movie theater. That is, the ambient lighting can be ambient lighting deployed in the movie theater.

[0087] For example, in one possible implementation, after the control device obtains the information of the image displayed by the display device, it can control the presentation effect of the ambient light in the target space area based on the color information in the image. For example, it can analyze the color information in the image and generate corresponding control commands. The control commands are then sent to the ambient light so that the ambient light presents the corresponding ambient effect according to the control commands. An example is described below.

[0088] In one possible implementation, the target space area can be divided into multiple preset areas. The ambient lighting effect in one of these preset areas (referred to as the first preset area) matches the first target color included in the image being displayed on the display device (referred to as the first image). The ambient lighting effects in the other preset areas besides the first preset area can match the colors included in the images subsequently displayed on the display device. Furthermore, the ambient lighting effects in different preset areas match the colors included in the images displayed on the display device at different times. For ease of understanding, examples are given below.

[0089] For example, suppose the target space is divided into N preset areas, where N is greater than or equal to 2. These N preset areas include the first preset area, the second preset area, the third preset area, ..., the Nth preset area. For instance, the second screen is displayed after the first screen, and this second screen includes the second target color. The third screen is displayed after the second screen, and this third screen includes the third target color. And so on, the Nth screen is displayed after the (N-1)th screen, and this Nth screen includes the Nth target color. Then the ambient lighting effect of the second preset area matches the second target color. Similarly, the ambient lighting effect of the third preset area matches the third target color. And so on, the ambient lighting effect of the Nth preset area matches the Nth target color.

[0090] For example, each of the aforementioned first target color, second target color, third target color, ..., Nth target color may include one or more colors. Taking the first target color as an example, the first target color may include one or more of any colors such as red, yellow, blue, green, cyan, blue, purple, pink, and orange. It is understood that the description of colors herein is merely illustrative and does not constitute a limitation on the embodiments of this application.

[0091] For example, in one possible implementation, the effect of the ambient light is matched with the target color included in the corresponding image, which may include the color of the ambient light matching the target color included in the corresponding image. For ease of understanding, the following description uses the example of the ambient light in the first preset area matching the first target color included in the first image.

[0092] For example, in one possible implementation, the ambient light in the first preset area may be the average color of a plurality of colors included in the first target color. For instance, in a specific implementation, the first image may include many colors. The control device can acquire the color of each pixel in the first image. Then, it performs cluster analysis on the acquired multiple colors to obtain K color categories. K is an integer greater than 1. The colors in each color category are as similar as possible, while the colors between different color categories are as different as possible. Then, it counts the number or proportion of pixels in the first image whose colors belong to each color category. For example, taking the number of pixels as an example, it can be counted that C1 pixels in the first image belong to the first color category among the K color categories. C2 pixels belong to the second color category among the K color categories. And so on, C... K The color of each pixel belongs to the Kth color category among the K color categories. Then, C1, C2, ..., C K The colors are sorted in descending order. The colors in the color category corresponding to the largest pixel count constitute the first target color. For example, assuming C1 is the largest, the colors in the first color category constitute the first target color. That is, the first target color includes one or more colors included in the first color category. Then, the average color of the colors included in the first target color is calculated. Then, the control device generates a control command based on the average color and sends the control command to the ambient lights in the first preset area. This causes the ambient lights in the first preset area to display a lighting effect with the average color according to the control command.

[0093] Alternatively, as an example, in another possible implementation, the ambient light in the first preset area displays a color that includes some or all of the colors included in the first target color. For instance, after determining the first target color in the first screen as described above, the control device generates a control command based on the first target color and sends the control command to the ambient light in the first preset area. This causes the ambient light in the first preset area to display a lighting effect in which the color includes some or all of the colors included in the first target color, according to the control command.

[0094] It is understood that the above-described implementation of matching the ambient light color with the target color included in the corresponding image is merely an example and does not constitute a limitation on the embodiments of this application. Furthermore, the above mainly uses the example of matching the ambient light color in the first preset area with the first target color included in the first image. The implementation of matching the ambient light color in other preset areas, such as the second or third preset areas, with the target color included in the corresponding image is similar and will not be described in detail here.

[0095] For example, in one possible implementation, the ambient light's presentation effect matches the target color included in the corresponding image, which may include the ambient light's brightness matching the brightness corresponding to the target color included in the corresponding image. Similarly, for ease of understanding, let's take the example of the ambient light's brightness in the first preset area matching the brightness corresponding to the first target color included in the first image. For example, the first target color in the first image can be determined according to the above description. Then, pixels in the first image whose color belongs to the first target color are searched. The brightness value of each found pixel is obtained. Then, in one possible example, the average of these brightness values ​​can be calculated. This average brightness value is the brightness corresponding to the first target color. Then, the control device can control the ambient light in the first preset area to present a brightness indicated by the average brightness value. Or, in another example, if the ambient light in the first preset area presents a color that includes some or all of the colors included in the first target color, then the average brightness value corresponding to each presented color can be searched in the first image. Taking one color in the first target color (referred to as color A) as an example, pixels belonging to color A can be searched in the first image. The system then obtains the brightness values ​​of each found pixel. Next, it calculates the average of these brightness values. This yields the average brightness value corresponding to color A. The same logic applies to other colors. Furthermore, when the control device controls the corresponding ambient light bead to display a certain color (e.g., color A), it can also control the brightness of the light displayed by the ambient light bead to be the brightness indicated by the average brightness value corresponding to that color (e.g., color A). It is understood that the description herein is merely illustrative and does not constitute a limitation on the embodiments of this application.

[0096] For example, in one possible implementation, the effect of the ambient light is matched with the target color included in the corresponding image, which may include the color temperature of the ambient light matching the target color included in the corresponding image. Similarly, for ease of understanding, the example of the ambient light in the first preset area matching the color temperature of the first target color included in the first image is described. For example, different image colors correspond to different color temperatures. A correspondence table between different image colors and different color temperatures can be preset. The first target color in the first image can be determined according to the above description. Then, the average color of the first target color is calculated. Then, the color temperature corresponding to the average color is found in the preset correspondence table. The control device can control the color temperature of the ambient light in the first preset area to be the color temperature corresponding to the average color. It is understood that the description here is only an example and does not constitute a limitation on the embodiments of this application.

[0097] For example, in one possible implementation, the first preset area is closer to the viewer served by the display device than the second preset area. Similarly, the second preset area is closer to the viewer served by the display device than the third preset area. And so on, the (N-1)th preset area is closer to the viewer served by the display device than the Nth preset area. That is, the preset area corresponding to the screen that is closer in display time to the first screen currently being displayed by the display device is closer to the viewer served by the display device. This means that while preserving the lighting atmosphere of the current screen, the spatial atmosphere corresponding to the subsequent screen can be created in advance, improving the viewing experience. For ease of understanding, an example is given below.

[0098] For example, in one possible implementation, the target space area is the vehicle's passenger compartment. Taking N=2 as an example, the first and second preset areas are areas within the passenger compartment. Exemplarily, if the display device is the vehicle's central control screen or passenger-side screen, and the viewer is located in the driver's seat and / or passenger seat, the first preset area is the front passenger compartment area including the driver's seat and / or passenger seat, and the second preset area is the rear passenger compartment area, as shown in Figure 3. Alternatively, in other possible implementations, see Figure 4. It can be seen that, compared to Figure 3, in Figure 4, the first preset area can be reduced towards the front of the vehicle, and the second preset area can be expanded towards the front of the vehicle.

[0099] Alternatively, taking N=3 as an example, the passenger compartment of the aforementioned vehicle may include a first preset area, a second preset area, and a third preset area. If the aforementioned display device is the vehicle's central control screen or passenger-side screen, and the viewer is located in the driver's seat and / or passenger-side seat, the first preset area is the area closest to the front of the vehicle, the third preset area is the area closest to the rear of the vehicle, and the second preset area is located between the first preset area and the third preset area, as shown in Figure 5.

[0100] It is understood that the above examples mainly use N=2 or N=3 as examples; other values ​​of N are similar and will not be elaborated further. Furthermore, Figures 3, 4, and 5 are merely illustrative and do not constitute a limitation on the embodiments of this application.

[0101] For example, in one possible implementation, similarly using N=2 as an example. Exemplarily, if the display device is a rear-seat display device of the vehicle, such as a display screen installed on the back of the driver's seat and / or passenger seat. Or, for example, it could be a projection screen installed on the back of the driver's seat and / or passenger seat, etc. And when the viewer is located in the rear seat of the vehicle, the first preset area is the rear passenger compartment area, and the second preset area is the front passenger compartment area including the driver's seat and / or passenger seat, as shown in Figure 6. Alternatively, in some other possible implementations, see Figure 7. It can be seen that, compared to Figure 6, the first preset area in Figure 7 can expand towards the front of the vehicle, and the second preset area can shrink towards the front of the vehicle. Since the viewer is facing the front of the vehicle, in the implementation shown in Figure 7, expanding the range of the first preset area allows the user to be more immersed in the atmosphere of the image being displayed on the device, improving the viewing experience.

[0102] Alternatively, taking N=3 as an example, the passenger compartment of the aforementioned vehicle can include a first preset area, a second preset area, and a third preset area. If the display device is a rear-seat display device and the viewer is located in the rear seat, the second preset area is the area closest to the front of the vehicle, the third preset area is the area closest to the rear of the vehicle, and the first preset area is located between the second and third preset areas, as shown in Figure 8. This design is because with the viewer in the rear seat, the first preset area in the middle can better create a lighting atmosphere that matches the first image being displayed on the device. The second preset area presents a lighting atmosphere that matches the second image displayed after the first image, and since the viewer is facing the front of the vehicle, the second preset area, being the area closest to the front, can create an atmosphere for the upcoming image in advance. The atmosphere corresponding to the third image displayed after the second image is created by the third preset area. The third image is displayed relatively later, so the third preset area can be located near the rear of the vehicle. The overall design can create a more immersive viewing atmosphere and improve the viewing experience.

[0103] It is understood that the above examples mainly use N=2 or N=3 as examples; other values ​​of N are similar and will not be elaborated further. Furthermore, Figures 6, 7, and 8 are merely illustrative and do not constitute a limitation on the embodiments of this application.

[0104] For example, in other possible implementations where the target space area is the vehicle passenger compartment, the spatial range from the first preset area to the Nth preset area can be adjusted adaptively according to the viewer's position. For ease of understanding, the following description uses N=2 as an example.

[0105] For example, referring to Figure 9, if the display device is the vehicle's central control screen and the viewer is sitting in the driver's seat, then the first preset area can be the area including the driver's seat. The second preset area can be the area including the passenger seat. Alternatively, in other implementations, the second preset area can be the area including both the passenger seat and the rear seats, etc.

[0106] For example, referring to Figure 10, if the display device is the vehicle's central control screen or the passenger-side screen, and the viewer is sitting in the passenger seat, then the first preset area can be the area including the passenger seat. The second preset area can be the area including the driver's seat. Alternatively, in other implementations, the second preset area can be the area including both the driver's seat and the rear seats, etc.

[0107] For example, if the display device is the vehicle's central control screen or the passenger-side screen, and the viewer is sitting in the driver's seat or the passenger seat, then the relevant descriptions in Figures 3 to 5 above can be referred to, and will not be repeated here.

[0108] For example, referring to Figure 11, if the display devices include one or more of the vehicle's central control screen, passenger-side screen, and rear-seat display devices, that is, one or more display devices in the vehicle are displaying the same image in conjunction, and there are viewers in the driver's seat and / or passenger seat, as well as in the rear seats, then the first preset area can be the area including the front and rear seats. The second preset area can be the area outside the first preset area, near the rear of the vehicle.

[0109] It is understood that the above mainly uses N=2 as an example; other values ​​of N are similar and will not be elaborated further. Furthermore, Figures 9, 10, and 11 are merely illustrative and do not constitute a limitation on the embodiments of this application.

[0110] For example, Figures 3 to 11 above illustrate a vehicle with two rows of seats. In a specific implementation, the passenger compartment of a vehicle may include three or more rows of seats. The specific division of the preset areas can be referred to the aforementioned descriptions, and will not be repeated here. Furthermore, for example, if the target space area is a space area in a movie theater or other viewing venue, then the specific division of the preset areas can be referred to the aforementioned descriptions of the target space area as a vehicle passenger compartment, and will not be repeated here.

[0111] In one possible implementation, the ambient lighting effect of the target space area can also be adjusted according to the preset feature objects included in the screen displayed by the display device. For example, when the screen displayed by the display device includes preset feature objects, the ambient lighting in the target space area presents a shape effect that matches the shape of the preset feature objects. For example, the shape of the preset feature objects can include various geometric shapes such as dots, lines, rings, or hearts. For example, dot-shaped preset feature objects can be stars in a displayed starry sky image, planets in a displayed universe image, or firework points in a displayed fireworks image. Line-shaped preset feature objects can be ribbons, rays, or chains in the displayed image. Ring-shaped preset feature objects can include any ring-shaped object such as a halo or a tire. Heart-shaped preset feature objects can include any heart-shaped object such as a heart-shaped marshmallow or a heart-shaped pattern. To facilitate understanding that the ambient lighting in the target space area presents a shape effect that matches the shape of the preset feature objects, the following description uses dot-shaped or line-shaped preset feature objects as examples.

[0112] In one possible implementation, as an example, when the preset feature object included in the screen displayed by the display device includes dot-shaped elements, the ambient light in the target space area presents a shape effect including dot-shaped elements. These dot-shaped elements are the preset feature objects. For ease of understanding, please refer to Figure 12. Figure 12 illustrates the target space area as the passenger compartment of a vehicle. If the screen displayed by the display device in the passenger compartment includes dot-shaped elements, the control device can analyze the acquired screen information to determine that the displayed screen includes dot-shaped elements. Therefore, the control device can generate control commands based on this and send the control commands to the ambient light in the passenger compartment. This allows the ambient light to present a corresponding dot-shaped ambient light effect according to the control commands, as shown in Figure 12. Figure 12 is merely an illustration and does not constitute a limitation on the embodiments of this application.

[0113] For example, in some possible implementations, the ambient lights in the aforementioned target space area present dynamic points, and the dynamic effect of the presented points matches the dynamic state of preset feature objects in the screen displayed by the display device. For example, the dynamic effect of the presented points may include one or more of the following: the direction of movement, the speed of movement, the speed of flashing, and the change in brightness of the points. That is, one or more of the direction of movement, the speed of movement, the speed of flashing, and the change in brightness of the points presented by the ambient lights match one or more of the direction of movement, the speed of movement, the speed of flashing, and the change in brightness of the point-like elements in the screen displayed by the display device. For ease of understanding, the following examples illustrate this.

[0114] For example, if the dot-like elements in the displayed image are in a divergent motion state, then in one example, if the ambient light in the target space area is in the form of a light strip, the brightness of the dot-like ambient light can present a breathing effect, gradually brightening from dark to light, to match the divergent motion state of the dot-like elements in the displayed image. For example, the breathing speed of the ambient light can match the divergent speed of the dot-like elements in the displayed image. In another example, if the ambient light in the target space area is in the form of an array of LED beads, then the dot-like ambient light can present a divergent motion lighting effect through this array of LED beads. For example, it can present a divergent motion lighting effect, with the LED beads lighting up sequentially from the center of the array outwards, so that it can match the divergent motion state of the dot-like elements in the displayed image. For example, the sequential lighting speed of the LED beads can match the divergent speed of the dot-like elements in the displayed image.

[0115] For example, if the dot-like elements in the displayed image are in a converging motion state, then in one example, if the ambient light in the target space area is in the form of a light strip, the brightness of the dot-like ambient light can present a breathing effect, gradually dimming from bright to dark, to match the converging motion state of the dot-like elements in the displayed image. For example, the breathing speed of the ambient light can match the converging speed of the dot-like elements in the displayed image. In another example, if the ambient light in the target space area is in the form of an array of LED beads, then the dot-like ambient light can present a converging motion lighting effect through this array of LED beads. For example, it can present a converging motion lighting effect where the LED beads light up sequentially from the outer edge of the LED bead array towards the center point, so that it can match the converging motion state of the dot-like elements in the displayed image. For example, the sequential lighting speed of the LED beads can match the converging speed of the dot-like elements in the displayed image.

[0116] For example, if the dot-like elements in the displayed image are moving in a single direction, then the dots in the ambient lighting of the target area can flow in a cyclical manner in that direction. For instance, taking the ambient lighting in the passenger compartment as an example, if the dot-like elements in the image move from near to far or from left to right on the display, then the dots in the ambient lighting can flow in a cyclical manner from rear to front of the vehicle. Similarly, if the dot-like elements move from far to near or from right to left on the display, then the dots in the ambient lighting can flow in a cyclical manner from front to rear of the vehicle. Exemplarily, the flow speed of the ambient lighting dots can be matched to the movement speed of the dot-like elements in the displayed image.

[0117] For example, if the dot-shaped elements in the displayed image are flashing, then the aforementioned dot-shaped ambient light can also flash accordingly. The flashing speed of the ambient light can match the flashing speed of the dot-shaped elements in the image.

[0118] It is understood that the above-described implementation of matching the dynamic effect of the ambient light points with the dynamic state of the preset feature objects in the screen displayed by the display device is merely an example and does not constitute a limitation on the embodiments of this application.

[0119] In one possible implementation, as an example, when the preset feature object included in the screen displayed by the display device includes a linear element, the ambient light in the target space area presents a linear shape effect. This linear element is the preset linear feature object. For ease of understanding, please refer to Figure 13. Figure 13 illustrates the target space area as the passenger compartment of a vehicle. If the screen displayed by the display device in the passenger compartment includes linear elements, the control device can analyze the acquired screen information to determine that the displayed screen includes linear elements. Therefore, the control device can generate a control command based on this and send the control command to the ambient light in the passenger compartment. This allows the ambient light to present a corresponding linear ambient light effect according to the control command, as shown in Figure 13. Figure 13 is merely an illustration and does not constitute a limitation on the embodiments of this application.

[0120] For example, in some possible implementations, the lines presented by the ambient lights in the aforementioned target space area are dynamic lines, and the dynamic effect of the presented lines matches the dynamic state of preset feature objects in the screen displayed by the display device. For example, the dynamic effect of the presented lines may include one or more of the following: the direction of movement, the speed of movement, the speed of flashing, and the change in brightness of the lines. That is, one or more of the direction of movement, the speed of movement, the speed of flashing, and the change in brightness of the lines presented by the ambient lights match one or more of the direction of movement, the speed of movement, the speed of flashing, and the change in brightness of the linear elements in the screen displayed by the display device. For ease of understanding, the following exemplary examples are provided.

[0121] For example, if the linear elements in the displayed image are in a divergent motion state, then in one example, if the ambient light in the target space area is in the form of a light strip, the brightness of the linear ambient light can present a breathing effect, gradually brightening from dark to light, to match the divergent motion state of the linear elements in the displayed image. For example, the breathing speed of the ambient light can match the divergence speed of the linear elements in the displayed image. In another example, if the ambient light in the target space area is in the form of an array of LED beads, then the linear ambient light can present a divergent motion lighting effect through this array of LED beads. For example, it can present a divergent motion lighting effect, with LED beads lighting sequentially from the center of the LED bead array outwards, so that it can match the divergent motion state of the linear elements in the displayed image. For example, the sequential lighting speed of the LED beads can match the divergence speed of the linear elements in the displayed image.

[0122] For example, if the linear elements in the displayed image are in a converging motion state, then in one example, if the ambient light in the target space area is in the form of a light strip, the brightness of the linear ambient light can present a breathing effect, gradually dimming from bright to dark, to match the converging motion state of the linear elements in the displayed image. For example, the breathing speed of the ambient light can match the converging speed of the linear elements in the displayed image. In another example, if the ambient light in the target space area is in the form of an array of LED beads, then the linear ambient light can present a converging motion lighting effect through this array of LED beads. For example, it can present a converging motion lighting effect where the LED beads light up sequentially from the outer edge of the LED bead array towards the center line, so that it can match the converging motion state of the linear elements in the displayed image. For example, the sequential lighting speed of the LED beads can match the converging speed of the linear elements in the displayed image.

[0123] For example, if the linear elements in the displayed image are moving in a single direction, then the linear patterns in the ambient lighting of the target area can flow in a cyclical manner in that direction. For instance, taking the ambient lighting in the passenger compartment as an example, if the linear elements in the image move from near to far or from left to right on the display, then the linear patterns in the ambient lighting can flow cyclically from rear to front. Similarly, if the linear elements move from far to near or from right to left on the display, then the linear patterns in the ambient lighting can flow cyclically from front to rear. Exemplarily, the flow speed of the ambient lighting lines can be matched to the movement speed of the linear elements in the displayed image.

[0124] For example, if the linear elements in the displayed image are flashing, then the aforementioned linear ambient light can also flash accordingly. The flashing speed of the ambient light can match the flashing speed of the linear elements in the image.

[0125] It is understood that the above-described implementation of matching the dynamic effect of the lines presented by the ambient light with the dynamic situation of the preset feature objects in the screen displayed by the display device is merely an example and does not constitute a limitation on the embodiments of this application.

[0126] The above description primarily uses point-like or line-like preset feature objects as examples, and the specific description does not constitute a limitation on the embodiments of this application. For example, in some implementations, the aforementioned point-like or line-like ambient lighting effects can be presented using ambient lighting in the form of light strips or LED arrays. For instance, Figures 12 or 13 above illustrate this using light strips. For preset feature objects with other geometric shapes such as rings or hearts, matching ring or heart-shaped ambient lighting effects can be presented using LED arrays. For example, taking the passenger compartment of the aforementioned vehicle as an example, LED arrays can be deployed at any feasible location in the passenger compartment, such as the top or left and right sides. The LED array can consist of multiple LEDs integrated into a supporting object, such as a base plate, or it can consist of LEDs from multiple light strips; this application embodiment does not limit this.

[0127] In one possible implementation, the ambient lighting effect in the target space area can also be adjusted according to the colors of the images displayed in different display areas of the display device. For example, if the image displayed in the first display area of ​​the display device includes a first type of color, and the image displayed in the second display area of ​​the display device includes a second type of color, the ambient lighting effect in the first sub-area of ​​the target space area matches the first type of color, and the ambient lighting effect in the second sub-area of ​​the target space area matches the second type of color. For ease of understanding, an example is provided below.

[0128] In one possible implementation, as shown in Figure 14, the display area of ​​the aforementioned display device can be divided into M1 sub-display areas in the horizontal direction, where M1 is greater than or equal to 2. These M1 sub-display areas are denoted as the first display area, the second display area, the third display area, ..., the M1th display area. Correspondingly, the aforementioned target space area can be divided into M1 sub-areas. For example, taking the passenger compartment of a vehicle as the target space area, the passenger compartment space area can be divided into M1 sub-areas along the horizontal direction, as shown in Figure 15. These M1 sub-areas are denoted as the first sub-area, the second sub-area, the third sub-area, ..., the M1th sub-area. Then, the i-th sub-area corresponds to the i-th display area. That is, the ambient lighting effect in the i-th sub-area matches the color of the image displayed in the i-th display area. The value of i is an integer between 1 and M1. For example, the image displayed in the i-th display area includes the i-th type of color. For example, the image displayed in the first display area includes the first type of color, the image displayed in the second display area includes the second type of color, and so on. The i-th color category may include one or more colors. The implementation method by which the control device determines the i-th color category included in the image displayed in the i-th display area can be exemplarily referred to the implementation method for determining the first target color in the first image described above, and will not be repeated here. For example, after determining the i-th color category included in the image displayed in the i-th display area, the control device can calculate the average color of the colors included in the i-th color category. Then, the control device generates a control command based on the average color and sends the control command to the ambient light in the i-th display area. This causes the ambient light in the i-th display area to display a lighting effect with the average color according to the control command.

[0129] In one possible implementation, as shown in Figure 16, the display area of ​​the aforementioned display device can be divided into M2 sub-display areas in the vertical direction, where M2 is greater than or equal to 2. These M2 sub-display areas are designated as a first display area, a second display area, a third display area, ..., the M2th display area. Correspondingly, the aforementioned target space area can be divided into M2 sub-areas. For example, taking the passenger compartment of a vehicle as the target space area, the passenger compartment space area can be divided into M2 sub-areas along the longitudinal direction, as shown in Figure 17. These M2 sub-areas are designated as a first sub-area, a second sub-area, a third sub-area, ..., the M2th sub-area. Then, the j-th sub-area corresponds to the j-th display area. That is, the ambient lighting effect in the j-th sub-area matches the color of the image displayed in the j-th display area. The value of j is an integer between 1 and M2. For example, the image displayed in the j-th display area includes the j-th color class. For instance, the image displayed in the first display area includes the first color class, the image displayed in the second display area includes the second color class, and so on. The j-th color category may include one or more colors. The implementation method by which the control device determines the j-th color category included in the image displayed in the j-th display area can be exemplarily referred to the implementation method for determining the first target color in the first image described above, and will not be repeated here. For example, after determining the j-th color category included in the image displayed in the j-th display area, the control device can calculate the average color of the colors included in the j-th color category. Then, the control device generates a control command based on the average color and sends the control command to the ambient light in the j-th display area. This causes the ambient light in the j-th display area to display a lighting effect with the average color according to the control command.

[0130] For example, Figures 14 to 17 are merely illustrative and do not constitute a limitation on the embodiments of this application. Furthermore, the above description primarily uses the passenger cabin as the target space area; the same principle applies to target space areas such as cinemas or other viewing venues, and will not be elaborated upon further.

[0131] In one possible implementation, the M1 sub-regions corresponding to the M1 sub-display areas can be target sub-regions located within the target space where viewers are seated. Alternatively, the M2 sub-regions corresponding to the M2 sub-display areas can also be target sub-regions located within the target space where viewers are seated. For example, the control device can adaptively adjust the target sub-regions where the M1 or M2 sub-regions are distributed based on the area where the viewers are located. For ease of understanding, the following example illustrates the distribution of M2 sub-regions within the target space where viewers are seated.

[0132] For example, let's take the passenger compartment as the target space area. Assume the display device is the central control screen and / or the front passenger seat in the passenger compartment, with viewers in the driver's seat and / or front passenger seat, while the rear seats are empty. Then, the target sub-area is the space outside the rear seats, including the front seats, as illustrated in Figure 18. In this case, compared to Figure 7, we can see that M2 sub-areas are distributed within the space of the front seats, i.e., within the target sub-area. This implementation allows the lighting atmosphere to more comprehensively surround the viewers, creating a more immersive viewing experience. Furthermore, the rear seat space, where no one is sitting, does not require ambient lighting, achieving energy savings. It is understood that Figure 18 is merely illustrative and does not constitute a limitation on the embodiments of this application. It is also understood that the description here is only one possible implementation example. In other examples, the display device may be a rear-seat display device serving viewers in the rear seats. Therefore, the target sub-area may be the space outside the front seats, including the rear seats. Based on this, the M2 sub-regions are distributed within the space of the rear seats. As for the aforementioned horizontal division of the M1 sub-regions, the target sub-region can be determined based on whether the viewer is seated on the left or right side of the passenger compartment. See Figure 18 for an illustrative example; details will not be elaborated here.

[0133] In one possible implementation, the ambient light at the corresponding position can be illuminated based on the audio playback position of the screen displayed on the display device to present a highlight lighting effect. For example, multiple speakers can be provided in the target space area. These speakers can be used to play audio, i.e., the sound corresponding to the screen displayed on the display device. Based on this, the control device can obtain the position of the speaker playing the sound, i.e., the position of the audio playback. For example, the audio playback position can be obtained through sound direction detection or pre-configured information, which is not limited in this embodiment. After obtaining the audio playback position, the corresponding ambient light can be determined based on that position. For example, a mapping table of ambient lights corresponding to each sound playback position can be pre-configured. Based on this, the ambient light corresponding to each position can be determined by looking up the table. The ambient light corresponding to each position can be, for example, one or more LEDs. After determining the ambient light corresponding to the playback position, the control device can generate a control command and send the control command to the corresponding ambient light to instruct the corresponding ambient light to present a highlight lighting effect. For example, see Figure 19, which illustrates a schematic diagram of a highlight lighting effect. As can be seen, in some possible implementations, the audio playback position can include multiple locations, which can correspond to the presentation of multiple highlight light effects. Figure 19 is only an example and does not constitute a limitation on the embodiments of this application.

[0134] For example, in one possible implementation, the color of the light source of the highlight can be any preset color or a color that matches the color of the image. This application embodiment does not limit this.

[0135] For example, in one possible implementation, the control device can also adjust the presentation effect of the highlight points according to the characteristics of the audio of the displayed image. For example, the audio characteristics may include one or more of the following: the rhythm points of the audio, the speed of change of the rhythm points, and the spectral energy of the sound frequency. For example, the control device can acquire the audio information of the displayed image and extract the corresponding audio characteristics. The specific implementation of extracting audio characteristics is not limited in this application embodiment. For example, in one example, the control device can control the breathing state of the presented highlight points according to the rhythm points of the audio and the speed of change of the rhythm points. For example, when a rhythm point appears, the brightness of the highlight point reaches its maximum and then gradually dims; when the next rhythm point appears, the brightness of the highlight point reaches its maximum again. This forms a highlight light effect that presents a breathing state according to the rhythm points and their changing speed. Alternatively, in another example, the brightness of the corresponding highlight point can be adjusted according to the spectral energy of the sound frequency. For example, the greater the energy, the greater the brightness of the highlight point. It is understood that the description herein is merely illustrative and does not constitute a limitation on the embodiments of this application.

[0136] For example, in one possible implementation, the audio playback positions of different screens displayed on the display device can be different. Then, the control device can control the corresponding ambient light to present a highlight effect based on the audio playback position corresponding to each displayed screen. For example, taking the first and second screens displayed on the display device as an example. Assuming the audio playback position of the first screen is position 1 and the audio playback position of the second screen is position 2, then during the display of the first screen, the control device can control the ambient light corresponding to position 1 to present a highlight effect. Optionally, for example, the control device can also adjust the highlight effect according to the characteristics of the audio of the first screen, as described above, and will not be repeated here. During the display of the second screen, the control device can control the ambient light corresponding to position 2 to present a highlight effect. Optionally, for example, the control device can also adjust the highlight effect according to the characteristics of the audio of the second screen, as described above, and will not be repeated here.

[0137] For example, in one possible implementation, both the first and second frames can be frames comprising multiple video images. Since each video frame is displayed for a very short time, if each frame corresponds to an ambient lighting effect, the lighting effects might change drastically, reducing the viewing experience. Because adjacent video frames are not significantly different, the granularity of the frame used to adjust the lighting can be based on the adjacent frames. This allows for a smooth transition of the ambient lighting effect, improving the user's viewing experience.

[0138] In summary, the proposed solution offers several advantages. First, it allows for the adjustment of ambient lighting based on the displayed image over time. For example, a first preset area can display an ambient lighting effect matching the currently displayed image, while a second preset area can display an ambient lighting effect matching the image to be displayed later, thus providing users with a more immersive viewing experience. Second, it allows for the presentation of ambient lighting shapes that match the shapes of characteristic objects in the displayed image, further enhancing the atmosphere and providing users with a more immersive viewing experience. Third, when different display areas on the display device display different colors, corresponding colors can be presented in their respective spatial areas to better enhance the atmosphere and provide users with a more immersive viewing experience. Fourth, it allows for the control of highlighting ambient lighting at corresponding positions based on the audio playback location. Optionally, the highlight presentation effect can also be adjusted in conjunction with audio characteristics to better enhance the atmosphere and provide users with a more immersive viewing experience.

[0139] For example, in one possible implementation, one or more of the following aspects of ambient lighting effects can be implemented: the first aspect (adjusting the ambient light based on the displayed image in the time dimension), the second aspect (presenting an ambient light shape effect that matches the shape of a feature object in the displayed image), the third aspect (presenting corresponding colors in corresponding spatial areas according to colors in different display areas of the display device), and the fourth aspect (controlling the ambient light at the corresponding position to present a highlight point according to the audio playback position of the image). For example, the control device can present a certain aspect of the lighting effect according to user instructions or default configuration. Or, for example, in one example, the control device can present the lighting effects of each aspect one by one according to a preset lighting effect presentation order. Or, for example, in one example, the control device analyzes the image being displayed on the display device and identifies the aforementioned preset feature object. Then, the corresponding ambient lighting effect can be controlled according to the second aspect. Optionally, one or more of the first and fourth aspects of the ambient lighting effect can be superimposed. If no preset feature object is identified on the display screen, the corresponding ambient lighting effect can be controlled according to the priority of the third aspect. Optionally, the ambient lighting effects of the first or fourth aspect can be superimposed. It is understood that the description herein is merely an example and does not constitute a limitation on the embodiments of this application.

[0167] It should be understood that the division of the units in the above-described device is only a logical functional division. In actual implementation, they can be fully or partially integrated into a single physical entity, or they can be physically separated. Furthermore, the units in the device can be implemented by a processor calling software; for example, the device includes a processor connected to a memory containing instructions. The processor calls the instructions stored in the memory to implement any of the above methods or to implement the functions of each unit in the device. The processor can be, for example, a general-purpose processor, such as a central processing unit (CPU) or a microprocessor, and the memory can be internal or external to the device. Alternatively, the units in the device can be implemented as hardware circuits. The functionality of some or all units can be achieved through the design of these hardware circuits, which can be understood as one or more processors. For example, in one implementation, the hardware circuit is an application-specific integrated circuit (ASIC). The functionality of some or all of the above units is achieved through the design of the logical relationships between the components within the circuit. In another implementation, the hardware circuit can be implemented using a programmable logic device (PLD). Taking a field-programmable gate array (FPGA) as an example, it can include a large number of logic gates. The connection relationships between the logic gates are configured through a configuration file, thereby achieving the functionality of some or all of the above units. All units of the above device can be implemented entirely through processor-invoked software, entirely through hardware circuits, or partially through processor-invoked software with the remaining parts implemented through hardware circuits.

[0168] In this application embodiment, a processor is a circuit with data processing capabilities. In one implementation, the processor can be a circuit with instruction reading and execution capabilities, such as a CPU, microprocessor, graphics processing unit (GPU) (which can be understood as a type of microprocessor), or digital signal processor (DSP). In another implementation, the processor can implement certain functions through the logical relationships of hardware circuits. These logical relationships of hardware circuits are fixed or reconfigurable. For example, the processor is a hardware circuit implemented as an ASIC or PLD, such as an FPGA. In a reconfigurable hardware circuit, the process of the processor loading a configuration document and configuring the hardware circuit can be understood as the process of the processor loading instructions to implement the functions of some or all of the above units. Furthermore, it can also be a hardware circuit designed for artificial intelligence, which can be understood as an ASIC, such as a Neural Network Processing Unit (NPU), Tensor Processing Unit (TPU), or Deep Learning Processing Unit (DPU).

[0169] As can be seen, each unit in the above device can be one or more processors (or processing circuits) configured to implement the above methods, such as: CPU, GPU, NPU, TPU, DPU, microprocessor, DSP, ASIC, FPGA, or a combination of at least two of these processor forms.

[0170] Furthermore, the units in the above devices can be integrated in whole or in part, or they can be implemented independently. In one implementation, these units are integrated together as a system-on-a-chip (SOC). The SOC may include at least one processor for implementing any of the above methods or implementing the functions of the units in the device. The at least one processor may be of different types, such as CPU and FPGA, CPU and artificial intelligence processor, CPU and GPU, etc.

The ambient lighting control device 2100 shown in Figure 21 can be the control device in the method described in the above embodiments. The ambient lighting control device 2100 includes: a processor 2101, a memory 2102, and a communication interface 2103.

[0172] For example, memory 2102 is used to store computer programs and data of ambient light control device 2100. Memory 2102 may include, but is not limited to, random access memory (RAM), read-only memory (ROM), erasable programmable read-only memory (EPROM), or compact disc read-only memory (CD-ROM).

[0173] The software or program code required for all or part of the functions of the ambient light control device 2100 in the above method embodiments is stored in the memory 2102.

[0174] In one possible implementation, if the software or program code required for some functions is stored in memory 2102, then processor 2101, in addition to calling the program code in memory 2102 to implement some functions, can also cooperate with other components to complete other functions described in the method embodiment. For example, it can cooperate with communication interface 2103 to implement the function of receiving or sending data.

[0175] The number of communication interfaces 2103 can be multiple, used to support the ambient light control device 2100 in communication, such as receiving or sending data or signals.
