Description

[Technical Field]

[0001] This application relates to ambient light technology, and more particularly to scene-based ambient light control technology. [Background technology]

[0002] For example, in a spatial environment such as a stage or a car cab, ambient lighting / atmosphere lamps are typically installed, which can change the color mode of their own lights to create various themes and atmospheres for the spatial environment, allowing users in the spatial environment to feel different experiences. These atmosphere lights, usually combined with background music, create an immersive experience for users, enhancing emotions and highlighting the atmosphere. FIG. 1 illustrates an exemplary light control system according to the prior art. As shown, this control process includes steps such as music capture 101, spectral / lyric feature extraction 102, atmosphere mode determination 103, and encoding command generation 104. In the music capture 101 stage, information about the currently playing music is acquired from the target space. Then, in the spectral / lyric feature extraction 102 stage, spectral energy distribution information of the music or emotional participial features of the music lyrics are extracted from the captured music information. Then, in the atmosphere mode determination step 103, a matching atmosphere theme is determined based on the spectral energy distribution information and the mood participle features, for example, selected from a database of multiple preset atmosphere theme modes, where each atmosphere theme mode corresponds to one light atmosphere effect or light plan. In the coded command generation step 104, a light control signal Lamp_Ctl is generated based on the light plan corresponding to the determined atmosphere theme mode, and the signal drives the driving circuit of the atmosphere lamp, causing the atmosphere lamp to emit a desired atmosphere light according to the light plan.

[0003] However, in fixed spatial environments such as music dance halls and music fountains, the light show format is relatively uniform, and the atmosphere lamps are generally controlled based solely on spectral or lyric characteristics, without sufficient correlation between the two. Vehicles such as automobiles also typically have ambient lighting, typically using atmosphere lamps, dashboards, etc. to create an atmosphere. However, the atmosphere created in the cab is generally uniform and does not take into account changes in the scene or environmental factors as the vehicle moves. Therefore, different atmosphere modes must usually be manually selected by a human. Summary of the Invention [Problem to be solved by the invention]

[0004] The present invention provides an improved atmosphere light control technology that can fully consider the external or internal environment of the target space, and the atmosphere effect is not limited to the background music, especially considering the special situation of moving scenes such as vehicles. Therefore, according to the present invention, the color of the atmosphere lamp changes with the change of different scenes, and can be matched with more characteristics of the music, improving the experience effect. [Means for solving the problem]

[0005] According to one aspect of the present invention, there is provided a light control method including the steps of detecting environmental features of a target space, including one or more first environmental features that exist independent of the target space and one or more second environmental features that exist dependent on the target space; determining an atmosphere mode for the target space based on the first and second environmental features; and matching a light plan based on the atmosphere mode and driving the atmosphere lamp to generate atmosphere light that matches the atmosphere mode.

[0006] According to another aspect of the present invention, there is provided a light control device including: a feature detection unit that detects environmental features of a target space, including one or more first environmental features that exist independent of the target space and one or more second environmental features that exist dependent on the target space; a mode determination unit that determines an atmosphere mode of the target space based on the first and second environmental features; and a light matching unit that matches a light plan based on the atmosphere mode and drives the atmosphere lamp to generate atmosphere light that matches the atmosphere mode.

[0008] Hereinafter, a control device and a method according to an embodiment of the present invention will be described in detail with reference to the drawings. While the drawings illustrate preferred embodiments of the present disclosure, it should be understood that the present disclosure is not limited to the embodiments described herein and can be embodied in various forms. On the contrary, these embodiments are provided so that the present disclosure will be thorough and complete, and will fully convey the scope of the present disclosure to those skilled in the art.

[0009] FIG. 2 illustrates a light control device 200 according to an embodiment of the present invention, which is adapted to generate corresponding light plans adaptively to different target space scenes and environments. In the following description, a vehicle cab is used as an example of the target space. As illustrated, the light control device 200 includes a feature detection unit 201, a mode determination unit 202, and a light matching unit 203. The feature detection unit 201 is configured to detect environmental features inside and outside the vehicle cab. The environmental features may include vehicle-independent external environmental features denoted as F_OUT and internal cab environmental features denoted as F_IN. According to the present invention, the external environmental features F_OUT may refer to time, weather at the vehicle's location, or characteristics of the vehicle's external surroundings. Such environmental features may be sky scenes, such as a sunset at dusk, rain, or snow, or scenes outside the vehicle window, such as grasslands or trees. As shown in FIG. 2, a vehicle typically includes various sensors, such as a temperature sensor, a system clock, a rain / snow sensor, a light sensor, and a front camera, designated by reference symbols S1 through S5 in the figure. These sensors are used to sense external environmental information and output corresponding environmental features (here, designated F_OUT1 through F_OUT5). For example, the temperature sensor S1 can be used to detect the temperature outside the vehicle and obtain a temperature feature F_OUT1. The system clock S2 can be read to obtain a current time feature F_OUT2. The rain / snow sensor S3 located on the windshield can output a feature signal F_OUT3 indicating that it is raining or snowing. The light sensor S4 can sense the light intensity outside the vehicle and output a light intensity signal F_OUT4. The vehicle MCU typically uses data from the light sensor to control automatic headlight activation. The front camera S5 can also obtain an external scene image F_OUT5 of the vehicle's current driving environment. The temperature sensor, system clock, rain / snow sensor, light sensor, and front camera shown here are merely examples, and the present invention is not limited to the types or numbers of sensors shown here, which may depend on actual needs and conditions.For example, the feature detection unit 201 can also collect external feature information provided by other sources, such as accessing a meteorological service center via a network to obtain weather information.

[0010] The cab interior environment features F_IN are features of the person in the cab or features collected through the interaction between the person and the human-machine interface. The person features here may be, for example, appearance features such as the number of people in the vehicle or the driver's appearance. As shown in FIG. 2, these features may be collected by an in-vehicle camera S1' installed in the cab. The person features may also be facial or emotional features of the person. These features may be determined by analyzing them using a central processing unit or other computing unit installed in the in-vehicle camera S1'. These features are collectively referred to as F_IN1 here. The person may also input features such as a current location or destination entered in a navigation device via the human-machine interface S2', which are referred to as F_IN2 here. Of course, the current location may be read by a GPS system. Similarly, the vehicle interior environment features in the present invention may also include any other features that may affect the atmosphere inside the vehicle. The external environment features F_OUT and internal environment features F_IN received by the feature detection unit 201 are not limited to those shown in the seven feature outputs in Fig. 2, but may be any other number and type of combination of external environment features F_OUT and internal environment features F_IN. Therefore, according to the present invention, the feature detection unit 201 detects F_OUT1 to F_OUT p p external environment features are collected and F_IN1 to F_IN qThe feature detection unit 201 collects q internal environment features indicated by p = p = q (p, q) = q (q). Note that in an embodiment of the present invention, the numbers p and q and the specific features to be collected may be set according to a specific situation. For example, in one exemplary scene, the feature detection unit 201 collects the vehicle's departure location F_IN1 = office, destination F_IN2 = home, number of occupants F_IN3 = 1, user's clothing color F_IN4 = blue, and vehicle status F_IN5 = power on but engine off, all of which are input by the user using the navigation system, and also obtains the current time F_OUT1 = 6:00 PM on a weekday via the system clock. The feature detection unit 201 transmits the collected external environment features F_OUT and internal environment features F_IN to the mode determination unit 202. For example, in this exemplary scene, the feature detection unit 201 outputs the detected environmental features {F_IN1=office, F_IN2=home, F_IN3=1, F_IN4=green, F_IN5=engine stopped with power on, F_OUT1=6:00 PM on a weekday} to the mode determination unit 202. Note that the collection of the environmental features by the feature detection unit 201 may be performed when a certain trigger event occurs, for example, when the user starts the vehicle with the engine stopped. However, in a normal driving state, the feature detection unit 201 may collect the environmental features according to a preset condition, for example, at regular time intervals.

[0011] According to one embodiment, upon receiving the features F_OUT1 and F_IN1 to F_IN5, the mode determination unit 202 uses them as attribute keywords and queries the mode database 204. The mode database 204 pre-stores a plurality of pre-designed atmosphere modes AMB_Mode, such as a romantic mode, a greeting mode, a conversation mode, and a holiday mode, and each atmosphere mode has a predetermined number of attribute features (F_OUT, F_IN). Note that one or more of the attribute features of different atmosphere modes may be shared by multiple modes or may be unique to each mode. The number of attribute features of each atmosphere mode may be the same or different. After receiving the attribute features F_OUT1 and F_IN1 to F_IN5 from the mode determination unit 202, the mode database 204 uses them as attribute keywords and queries the matching records. For example, in this example, when the values ​​of the environmental features are (F_OUT1=6 PM on a weekday, F_IN1=work, F_IN2=home, F_IN3=1, F_IN4=blue, F_IN5=engine off with power on), the current scene is determined to be "weekday leaving work scene," so the search result is determined to be "rest mode" and its use is recommended to the user.The mode determination unit 202 then transmits the mode determination result, "rest mode," to the light matching unit 203.

[0012] The light matching unit 203 may select a matching light plan according to the received "rest mode." For example, to create a breathing ocean atmosphere lamp effect to allow the user to relax and rest, the light matching unit 203 may select a light plan "Sea_Plan" featuring "ocean" from the pre-generated light plan database 205 and provide the light plan "Sea_Plan" to the encoding circuit 206. According to the present invention, the light plan database 205 pre-stores a plurality of light plans, each corresponding to one or more atmosphere modes AMB_Mode. Here, the encoding circuit 206 may generate a light control signal "Lamp_Ctl" based on the light plan "Sea_Plan," so that the light driving circuit turns on the atmosphere lamp and controls the atmosphere lamps, dashboard, etc. in the vehicle to emit light rays having the ocean effect.

[0013] In this embodiment, the mode determination unit 202 determines the appropriate ambience mode AMB_Mode based on database query and feature matching techniques. Meanwhile, in another embodiment of the present invention, when many external and internal environmental features are input, the mode determination unit 202 may intelligently match the appropriate ambience mode by calling a trained ambience matching model to process the input features, where the ambience matching model may be implemented based on deep machine learning such as a neural network model.

[0014] In the above-described embodiment, if a user enters a vehicle with the engine stopped, the vehicle generates an "ocean" atmosphere light when the user's entry is detected. In this case, the vehicle is stationary, i.e., the engine is stopped with the power on. In another embodiment of the present invention, the atmosphere light based on the vehicle environment may change as the vehicle moves, i.e., as the traveling scene changes. For example, if the front camera S5 of the vehicle detects a wheat field ahead while the vehicle is moving, the mode determination unit 202 adjusts the atmosphere mode based on the image collected by the front camera, and the light matching unit 203 adjusts the light plan, for example, adjusting or temporarily adjusting the atmosphere light to a golden color corresponding to the wheat field. After a certain period of driving, if the front camera S5 detects a sea ahead, the light plan is readjusted so that the atmosphere light becomes blue. Note that the new light plan created here is only temporary and is merely an adjustment made to adapt to different scenes; it does not affect the light plan previously stored in the light plan database.

[0015] According to another example, when the feature detection unit 201 detects that the travel scene has changed, the mode determination unit 202 first determines whether the environmental feature causes a change in the atmosphere mode. If the change does not cause a change in the mode, the mode determination unit 202 can directly instruct the light matching unit 203 to adjust the light plan based on the changed environmental feature. For example, in the above example, if the front camera S5 detects that there is a wheat field ahead, and the mode determination unit 202 determines that the change will not affect the "rest mode," the light matching unit 203 can adjust the light plan to adjust or temporarily adjust the atmosphere lamp to a golden color corresponding to the wheat field. However, if the mode determination unit 202 determines that the change will affect the "rest mode," a new atmosphere mode is determined, and a new light plan is obtained through matching by the light matching unit 203.

[0016] In the above embodiment, when the vehicle environment is recognized to match the atmosphere lamps, the vehicle driver or passengers typically perform some activity inside the vehicle, such as playing music, and therefore multimedia information is present in the spatial scene. This multimedia information may also affect the user's experience to some extent. Therefore, the media information may be analyzed and the atmosphere mode AMB_Mode may be controlled based on the analysis results. For example, a vehicle is typically equipped with media devices such as a CD player or radio. When listening to music played on these devices in the vehicle, it is clear that the atmosphere varies depending on the type of music. According to the configuration of the embodiment of the present invention, the atmosphere mode inside the vehicle may be set according to the music content while music is being played. Figure 3 is a diagram showing a light control device according to another embodiment of the present invention.

[0017] 3, the light control device 300, in addition to the feature detection unit 301, the mode determination unit 302, and the light matching unit 303, further includes a music capture unit 306, a feature extraction unit 307, and a synthesis unit 308. In this example, the operation processes of the feature detection unit 301, the mode determination unit 302, and the light matching unit 303 are substantially similar to those of the feature detection unit 201, the mode determination unit 202, and the light matching unit 203 shown in FIG. 2, so they will not be repeated here. In addition, for the sake of brevity, some other features of the light control device are also omitted.

[0018] The music capture unit 306 is configured to acquire information about music being played in the vehicle cabin. This music may be music being played on a sound box or music information acquired by a music console such as a CD player. The music capture unit 306 may temporarily store the acquired music information in a buffer (not shown). The feature extraction unit 307 then reads the music playback information from the buffer and processes it to identify feature objects (Objects) included in the playback information. According to an example of the present invention, a feature object (Object) refers to an object with specific visual characteristics, such as a "bird," "ocean," or "grassland," that may be included in the lyrics of the music being played. Such feature objects allow for the presentation of a specific image. The feature extraction unit 307 can first extract lyrics from the music and then analyze specific feature objects (Objects) included in the lyrics, for example, using conventional natural language understanding (NLU) technology. It is clear that different feature objects may appear in the same song as the lyrics are played. After analyzing the feature objects included in the music, the feature extraction unit 307 provides information about the feature objects to the synthesis unit 308. The synthesis unit 308 can adjust the light plan determined by the light matching unit 303 to present the feature object Object in atmosphere light. For example, if the feature extraction unit 307 determines that the lyrics include a bird, the mode determination unit 302 determines "rest mode," and therefore the light matching unit 303 determines a simple light blue atmosphere light plan Sea_Plan. Then, the synthesis unit 308 can modify Sea_Plan to present an image of the bird in light blue atmosphere light; for example, by using other colored lights in the overall light blue atmosphere light, an image of the bird can be presented against a yellow background atmosphere.

[0019] In another example of the present invention, when analyzing music playback information, the feature extraction unit 307 can not only recognize feature objects (Objects) contained in the playback information, but also determine song features of the currently played music, such as melody features, note features, and spectral energy features of the music. The feature extraction unit 307 can listen to the notes or melody of the currently played music using a trained deep machine learning algorithm. Obviously, a melody with a strong rhythm can create a lively atmosphere, while a melody with a gentle rhythm can create a soothing atmosphere, both of which can be reflected in specific atmosphere lamp effects. For example, an example of melody recognition can be chord recognition. For example, a Melodic Pitch Class Profile (MPCP) feature can be defined by performing a time-frequency transform on the music signal using a short-time Fourier transform (STFT), and then chord recognition can be performed using a conditional random field (CRF) model. In another example, when analyzing the music playback information, the feature extraction unit 307 may determine the spectral energy distribution of the music being played by a signal processing technique. Thus, the synthesis unit 308 uses the feature objects (Object) identified by the feature extraction unit 307 and, for example, a melody (Melody) to adjust the light plan determined by the light matching unit 303, and inputs the adjusted light plan to the encoding circuit 304 to generate a light control signal (Lamp_Ctl) to control the atmosphere lamp to change or flash according to the learned musical notes, melody, or spectral energy distribution, and embed a specific feature object (e.g., a bird) in the atmosphere light.

[0020] Although the above-described embodiment of the present invention describes the determination of the atmosphere mode and the atmosphere light using the cab of a car as an example, the present invention is not limited thereto and can be applied to any target space where an atmosphere needs to be enhanced using an atmosphere lamp. The target space here may be any spatial environment, not limited to an enclosed space, but also an open space. Such a target space may be equipped with an atmosphere lamp and other possible media playback devices, and may be, for example, a movie theater, a karaoke bar (KTV), a vehicle, etc.

[0021] 4 shows a flowchart of an atmosphere lamp control method according to an embodiment of the present invention, which is adapted to different target space scenes and environments to generate corresponding light plans. In the following example, the control of atmosphere lights in a car is also taken as an example.

[0022] In step 401, environmental features inside and outside the cab of the automobile are detected, where the environmental features may include one or more external environmental features F_OUT that are independent of the vehicle, or one or more environmental features F_IN inside the cab. For example, in one exemplary scene, with the engine stopped, it is detected that the user has input using the navigation system the vehicle's departure location F_IN1 = work, destination F_IN2 = home, number of occupants F_IN3 = 1, user's clothing color F_IN4 = blue, and vehicle status F_IN5 = engine stopped with power on, and the current time F_OUT1 = 6 PM on a weekday via the system clock is also obtained.

[0023] In step 403, the external environment features F_OUT and internal environment features F_IN collected in step 401 are received. For example, in this exemplary scene, {F_IN1=office, F_IN2=home, F_IN3=1, F_IN4=green, F_IN5=power on, engine off, F_OUT1=6 PM on a weekday} is received. Based on the received features F_OUT1 and F_IN1 to F_IN5, an appropriate atmosphere mode for the current scene is determined. This may be achieved using a conventional database query technique, or a neural network model trained by deep learning may be used to process the external environment features F_OUT and the internal environment features F_IN to determine an appropriate atmosphere mode. Here, if the values ​​of the environmental characteristics are (F_OUT1 = 6 PM on a weekday, F_IN1 = work, F_IN2 = home, F_IN3 = 1, F_IN4 = blue, F_IN5 = engine stopped with power on), it can be determined that the current scene is a "weekday leaving work scene," and the system recommends that the user use "break mode."

[0024] In step 405, a matching light plan can be selected based on the received "rest mode," for example, to create a sea-like atmosphere lamp effect to help the user relax and rest. Here, a database query technique can be used to select a light plan, Sea_Plan, featuring the "sea" theme, from a database in which light plans are pre-stored. This light plan, Sea_Plan, is then provided to an encoding circuit to generate a light control signal, Lamp_Ctl, which causes the light driving circuit to turn on the atmosphere lamp and control the atmosphere lamps in the vehicle to emit light rays with the "sea" effect. The determined atmosphere mode and light plan may be adjusted according to changes in the environmental characteristics collected in step 401.

[0025] FIG. 5 shows a flowchart of a light control method according to another embodiment of the present invention. Similar to the flow shown in FIG. 4, in step 501, environmental features of a target space are detected, including one or more external environmental features F_OUT and one or more internal environmental features F_IN. In step 503, an atmosphere mode suitable for the current target space is determined based on the external environmental features F_OUT and the internal environmental features F_IN. Then, in step 505, a light plan is matched based on the atmosphere mode. Assume that a "rest mode" is determined for the current scene environment, and a light plan "Sea_Plan" featuring "sea" is obtained through matching.

[0026] Then, in step 507, it is determined whether multimedia information, such as music, exists in the current target space. If music information is detected, the process proceeds to step 509, where the currently played music information is analyzed to determine whether the music contains lyrics. If it is determined that the music is absolute music, i.e., does not contain lyrics, the process proceeds to step 511, where the melody feature or spectral energy distribution feature of the current music is determined. Then, in step 513, the determined melody feature or spectral energy distribution feature is used to adjust the light plan Sea_Plan determined in step 505, so that the originally determined atmosphere lamp can be transformed according to the determined melody feature or spectral energy distribution feature. Then, in step 515, the adjusted light plan is processed by an encoding circuit and then provided to the light driving circuit in the form of a light control signal Lamp_Ctl.

[0027] If it is determined in step 509 that the music contains lyrics, proceed to step 517, extract the lyrics from the music, for example by natural language processing (NLP) techniques, and process the lyrics, then in step 519, determine any imageable and presentable feature objects (Object) that may be included in the lyrics, for example birds, butterflies, etc., and select one or more candidate objects from the recognized feature objects, then proceed to step 513, and use the selected candidate objects, for example butterflies, to modulate the light plan determined in step 505 so that a butterfly pattern appears in the final atmosphere light. Then, execute step 515 to generate a modulated light control signal Lamp_Ctl. If no music is detected in the target space in step 507, the process proceeds to step 515, where a control signal for the light plan "ocean" determined in step 505 is output.

[0028] In this example, a music signal is used as an example to explain how a predetermined atmosphere mode can be adjusted or the light plan can be adjusted without changing the atmosphere mode, but the present invention is not limited to this and adjustments may be made based on any other collectable information, thereby achieving a better atmosphere effect and user experience.

For example, the control devices in FIGS. 2 and 3 are configured in the form of units.
