Description

[Technical Field]

[0001] This invention relates to a lighting control technology, and more particularly to a lighting effect control method and a lighting control device. [Previous Technology]

[0002] Background Technology With the advancement of technology, the lighting effects of computer peripherals are becoming increasingly diverse. For example, users can adjust the color, mode, and brightness of lighting effects through software.

[0003] However, existing lighting effect control has some drawbacks and shortcomings: (1) Lack of interconnection between lighting effect systems: The interconnection range of existing lighting effect systems is limited to a single host and its connected devices. The lighting effects of different lighting effect systems cannot be interconnected, resulting in insufficient coordination and consistency of the overall lighting effect. (2) Cumbersome virtual space settings: Users need to manually place virtual hosts and virtual devices in the virtual space in the lighting effect settings program to define the lighting effect interconnection relationship between the host and the device. When there are many devices, this method requires many steps and time, and it is easy for the virtual device position to be inconsistent with the actual device position. (3) Lack of continuous interconnection between virtual space and actual space: The virtual space and actual space of existing lighting effect systems lack continuous interconnection. The lighting effect will not be updated according to the position changes of the host and device, which limits the dynamic changes and spatial interactivity of the lighting effect. [Summary of the Invention]

[0004] The present invention provides a lighting effect control method and a lighting control device, which can solve the above problems and provide a more convenient, more accurate and more interactive lighting effect experience.

[0006] The lighting control device of this embodiment includes (but is not limited to) a communication transceiver and a processor. The communication transceiver is used to transmit signals. The processor is coupled to the communication transceiver and configured to: locate one or more light source devices through image recognition to generate positioning information, wherein the image recognition analyzes the image features of one or more light source devices, the positioning information includes the position of the light source device in actual space, and each light source device includes one or more light-emitting elements; and control the light-emitting elements of the light source device according to the positioning information.

[0007] Based on the above, the lighting effect control method and lighting control device of the present invention determine the position of the light source device in the actual space through image recognition, and control the light-emitting element of the light source device accordingly. Therefore, by simply placing the light source device in the designated position and setting the corresponding lighting effect for the space, the setting can be easily completed, thereby achieving a coordinated and consistent lighting effect experience.

In one embodiment, processor 112 is used to perform all or part of the operations of lighting control device 110, and may load and execute one or more software modules, files, and / or data stored in memory.

[0015] In one embodiment, the processor 112 runs a lighting effect control application (hereinafter referred to as lighting effect software).

For example, the field of view covers all or part of the light source devices 120. The images may be derived from photographs or videos.

[0017] The light source device 120 may be a smartphone, tablet, wearable device, laptop, desktop computer, server, smart home appliance, smart assistant device, in-vehicle system, conference phone, home game console, personal computer, artificial intelligence PC (AI PC), or other electronic device serving as the host device.

[0018] For example, FIG2 is a schematic diagram of a lighting system 1-1 according to an embodiment of the present invention. Referring to FIG2, the lighting system 1-1 includes a host device 120-1 (taking a desktop host as an example) and an auxiliary device 120-11 (taking a display device as an example), 120-12 (taking a display device as an example), 120-13 (taking a mouse device as an example), 120-14 (taking a keyboard device as an example) connected to the host device 120-1 (taking a laptop computer as an example), and auxiliary devices 120-21 (taking an earphone as an example), 120-22 (taking a mouse device as an example), 120-33 (taking a keyboard device as an example) connected to the host device 120-2 (taking a laptop computer as an example), and a host device 120-3 (taking an earphone as an example).

[0019] It should be noted that the number and type of the host device and its auxiliary devices shown in Figure 2 are only for illustrative purposes. They can be adjusted according to actual needs in other application scenarios, and the embodiments of the present invention are not limited thereto.

[0020] The light source device 120 includes a communication transceiver 121, a processor 122, and one or more light-emitting elements 123.

[0021] The implementation and functions of the communication transceiver 121 and the processor 122 can be referred to the above description of the communication transceiver 111 and the processor 122 respectively, and will not be repeated here.

[0022] In one embodiment, the communication transceiver 121 is used to connect with the lighting control device 110 and / or other light source devices 120, and to transmit or receive signals accordingly. The signals can carry various types of data and / or instructions. Taking FIG2 as an example, the host device 120-1 is connected to the auxiliary devices 120-11~14, and the host device 120-1 is connected to the host device 120-2.

[0023] The processor 122 is coupled to the communication transceiver 121 and the light-emitting element 123. In one embodiment, the processor 122 is used to perform all or part of the operations of the light source device 120, and can load and execute one or more software modules, files and / or data stored in the storage. In one embodiment, the processor 122 runs lighting effect software.

[0024] The light-emitting element 123 may be a light bar, a light-emitting keycap, a light-emitting scroll wheel, a light-emitting sign, a light-emitting fan, a screen backlight, a light-emitting earpiece, an LED backlight, an RGB light strip, or other light-emitting elements. In one embodiment, the light-emitting element 123 may emit light of a specified color, brightness, and / or color temperature, and / or flash according to a specified light emission frequency.

[0025] In some embodiments, a light source device 120 may serve as a lighting control device 110.

[0026] The method described in the embodiments of the present invention will be described below in conjunction with the devices, components and modules in lighting systems 1 and 1-1. Each step of this method may be adjusted according to the implementation situation, and is not limited thereto.

[0027] Figure 3 is a flowchart of a lighting effect control method according to an embodiment of the present invention. Referring to Figure 3, the processor 112 of the lighting control device 110 locates one or more light source devices 120 through image recognition to generate positioning information (step S310). Specifically, the processor 112 acquires an image captured by the image capturing device 113. The processor 112 locates one or more light source devices 120 in the image through image recognition.

[0028] Image recognition is, for example, image feature retrieval or localization based on feature detection and matching (e.g., Scale-Invariant Feature Transform (SIFT), Speeded-Up Robust Features (SURF), Oriented Fast and Rotated BRIEF (ORB)), image feature retrieval or localization based on machine learning models (e.g., deep learning models, random forest tree models, or support vector machine models), Simultaneous Localization and Mapping (SLAM), or projection matrix methods.

[0029] Image recognition analyzes the image features of one or more light source devices 120. Location information includes the position of one or more light source devices 120 in real space. Real space represents the space of the real world. Position can be defined using coordinates or relative position. For feature detection and matching-based localization, the processor 112 can match image features with features of images at known locations in a database, and infer the position and orientation of the light source device 120 in the image based on the number of matches and spatial relationships. For image retrieval based on a machine learning model, the processor 112 can extract image features from the image using a machine learning model and retrieve similar images (with localization information) from the image database, thereby inferring the position of the light source device 120 in the image. For SLAM, this algorithm combines image recognition, sensor data (e.g., inertial measurement unit (IMU) or accelerometer), and geometric estimation, simultaneously estimating the pose of the image capturing device 113 and building an environmental map, and inferring the position of the light source device 120 in the image accordingly. For localization based on machine learning models, the position of the light source device 120 can be estimated directly by inputting the image into the model. For the projection matrix method, the processor 112 extracts image feature points from the image, establishes a projection equation based on these image feature points, and obtains the coordinates of the image feature points and the position of the light source device 120 by solving the projection equation.

[0030] Image recognition-based positioning can simplify the steps required to define the device location in an application and reduce positioning time. However, there are many other image recognition-based positioning methods, and users can adjust them according to their actual needs.

[0031] Figure 4 is a flowchart of positioning control according to an embodiment of the present invention. Referring to Figure 4, the image features of the light source device 120 include the positioning lighting effect of the light-emitting element 123. Hereinafter, any lighting effect can be light of a specified color, brightness, and / or color temperature, and / or flashing at a specified emission frequency. The lighting effect may be a combination of light of various colors, brightness, and / or color temperatures. The positioning lighting effect is a lighting effect used in the positioning mode. The processor 112 can generate a positioning indication signal based on the positioning lighting effect (step S410). The positioning indication signal is used to indicate the emission of the positioning lighting effect. That is, the light source device 120 can control its light-emitting element 123 to emit light of a specified color, brightness, and / or color temperature, and / or flash at a specified emission frequency, based on the positioning indication signal. Furthermore, the positioning indication signal also includes identification information of the light source device 120. Thereby, the lighting control device 110 and the light source device 120 can transmit the positioning indication signal to the designated light source device based on this identification information.

[0032] In one embodiment, the processor 112 can configure the positioning lighting effect of each light source device 120, so that each light source device 120 has a corresponding positioning lighting effect (i.e., establish the association between the light source device 120 and the positioning lighting effect). That is to say, the positioning lighting effects of different light source devices 120 may be different.

[0033] For example, Figure 5 is a schematic diagram of the positioning lighting effect according to an embodiment of the present invention. Referring to Figure 5, the main unit 120-1 and its auxiliary units 120-11 to 120-14 correspond to the first positioning lighting effect (hereinafter referred to as positioning lighting effect) (taking orange light as an example). The main unit 120-2 and its auxiliary units 120-21 to 120-23 correspond to the second positioning lighting effect (taking purple light as an example). The main unit 120-3 and its auxiliary units 120-31 to 120-33 correspond to the third positioning lighting effect (taking pink light as an example). The main unit 120-4 and its auxiliary unit 120-41 correspond to the fourth positioning lighting effect (taking bright green light as an example). The main unit 120-5 and its auxiliary units 120-51 to 120-53 correspond to the fifth positioning lighting effect (taking bright blue light as an example).

[0034] It should be noted that the positioning lighting effect corresponding to each light source device 120 can be automatically configured or set according to user instructions. The example shown in Figure 5 illustrates that the host device and its auxiliary devices correspond to the same positioning lighting effect, but in other embodiments, they may correspond to different positioning lighting effects. In addition, the issuance of the positioning indication signal may be based on user instructions received by the lighting effect software or based on predefined events.

[0035] Referring to Figure 4, the processor 112 transmits a positioning indication signal to the corresponding light source device 120 via the communication transceiver 111 (step S420). Based on the aforementioned association between the light source device 120 and the positioning lighting effect, the processor 112 can transmit a positioning indication signal indicating a specific positioning lighting effect to the corresponding light source device 120 via the communication transceiver 111. After receiving the positioning indication signal, the light source device 120 enters the positioning mode and can emit the specified positioning lighting effect through its light-emitting element 123. For the system formed by the host device and the auxiliary devices, the lighting control device 110 can transmit the positioning indication signal to the host device, and the host device can transmit the positioning indication signal to its auxiliary devices.

[0036] Next, the image capturing device 113 captures an image. For example, FIG6 is a schematic diagram of an image IM1 captured according to an embodiment of the present invention. Referring to FIG6, this is the image IM1 captured by the image capturing device 113. This image IM1 includes images of the main devices 120-1, 120-2, 120-4, 120-5 and the auxiliary devices 120-11~14, 120-21~120-23, 120-41, 120-51~120-53.

[0037] The processor 112 can determine the position of the light source device 120 in the actual space based on the positioning lighting effect (step S430). As described above in the positioning method based on image recognition, the processor 112 can identify the positioning lighting effect specified by the positioning indication signal, and determine the number and position of the light source device 120 corresponding to each positioning lighting effect. Taking FIG6 as an example, for the first positioning lighting effect, three light source devices 120 (i.e., auxiliary devices 120-12 to 120-14, but ignoring the auxiliary device 120-11 with incomplete positioning lighting effect) and their positions (e.g., in the upper left or rear left) can be identified in the image IM1.

[0038] Referring to Figure 3, the processor 112 of the lighting control device 110 controls the light-emitting element of the light source device 120 based on the positioning information (step S320). Specifically, the positioning information obtained by locating the light source device 120 through image recognition (i.e., the position of the light source device in actual space) can be used to understand the relative positions between the light source devices 120. Understanding the relative positions between these light source devices 120 will help to make the lighting effects of these light source devices 120 coordinated or linked. That is, the embodiments of the present invention can provide a consistent or coordinated lighting effect for the entire light source device 120.

[0039] More specifically, FIG7 is a flowchart of effect rendering according to an embodiment of the present invention. Referring to FIG7, the processor 112 of the lighting control device 110 can map the light source device 120 to a virtual color space based on positioning information (step S710). Specifically, the virtual color space is the color space of a virtual space established by the lighting effect software. In one embodiment, the virtual color space defines the color / color of each position in the virtual space. In another embodiment, the virtual color space defines the color / color, brightness, color temperature, and / or flicker frequency of each position in the virtual space.

[0040] The position in the actual space corresponds to the position in the virtual color space or the virtual space. For example, FIG8 is a schematic diagram of a virtual color space VCS1 according to an embodiment of the present invention. Referring to FIG6 and FIG8, the processor 130 can map the host devices 120-1, 120-2, 120-4, 120-5 and the auxiliary devices 120-11~14, 120-21~120-23, 120-41, 120-51~120-53 to the same position in the virtual color space VCS1 based on the positioning information (i.e., the position of the light source device 120 in the actual space) identified from the image IM1 of FIG6. For example, the auxiliary device 120-12 is located to the left of the host device 120-2 in the image IM1 of FIG6. Therefore, in the virtual color space VCS1, the auxiliary device 120-12 is still located to the left of the host device 120-2.

[0041] Referring to Figure 7, the processor 112 can determine the spatial lighting effect of the virtual color space (step S720). The spatial lighting effect is the lighting effect for the entire virtual color space.

[0042] In one embodiment, when the spatial lighting effect is a gradient effect, the processor 112 can define the starting color, ending color, and gradient direction of the gradient effect in the virtual color space. The starting color, ending color, and gradient direction may be defined by user instructions received by the lighting effect software, or they may be automatically configured.

[0043] In one embodiment, when the spatial lighting effect is a still image, the processor 112 can map the still image to a virtual color space. That is, it determines the position of one or more pixels in the still image corresponding to the virtual color space. The still image may be a still image file uploaded by user instructions, or it may be automatically configured.

[0044] In one embodiment, when the spatial lighting effect is a dynamic image, the processor 112 can map the dynamic image to a virtual color space. That is, it determines the position of one or more pixels in the dynamic image corresponding to the virtual color space. The dynamic image may be a dynamic / movable image file uploaded by user instructions, or it may be automatically configured.

[0045] Referring to Figure 7, the processor 112 can render the spatial lighting effect to the light-emitting elements of the light source device in the virtual color space to produce a rendering result (step S730). The rendering result refers to the association between each position in the virtual color space and the corresponding position of the spatial lighting effect in terms of color / brightness, color temperature, and / or flicker frequency, and to give the light source device 120 and its light-emitting elements 123 in the virtual color space the corresponding color / brightness, color temperature, and / or flicker frequency. In other words, the rendering result associates the position of one or more light-emitting elements in the virtual color space with the lighting effect of the spatial lighting effect at the same position.

[0046] For example, FIG9A is a schematic diagram illustrating the rendering result SLE1 of the gradient effect according to an embodiment of the present invention. Referring to FIG9A, the processor 112 performs gradient rendering on the virtual color space VCS1 according to the starting color SC1, the ending color TC1, and the gradient direction (i.e., from the upper left to the lower right), thereby producing the rendering result SLE1 shown in FIG9A.

[0047] Figure 9B is a schematic diagram illustrating the rendering result of a static or dynamic image according to another embodiment of the present invention. Referring to Figure 9B, the processor 112 maps the pixel colors of the static or dynamic image to the corresponding positions in the virtual color space VCS1, thereby generating the rendering result SLE2 shown in the figure. It should be noted that dynamic image rendering requires rendering the image frame by frame and updating the color information of the virtual color space to achieve dynamic lighting effect changes.

[0048] Referring to Figure 7, the processor 112 can control the light-emitting element 123 of the light source device 120 according to the rendering results (step S740). As explained above, the rendering results SLE1 and SLE2 have defined the lighting effects (e.g., color / color, brightness, color temperature, and / or flicker frequency) corresponding to the light source device 120 and its light-emitting element 123 in the virtual color space. Therefore, the processor 112 can instruct the light source device 120 in the virtual color space to emit light according to the defined lighting effects.

[0049] Figure 10 is a flowchart of a light emission indicator according to an embodiment of the present invention. Referring to Figure 10, the processor 112 can generate a light emission indicator signal based on the rendering result (step S1010). The light emission indicator signal is used to indicate the emission of a corresponding lighting effect. That is, the light source device 120 can control its light-emitting element 123 to emit light of a specified color, brightness, and / or color temperature, and / or emit a flashing light of a specified emission frequency, based on the light emission indicator signal. The aforementioned light of a specified color, brightness, and / or color temperature and / or flashing light of a specified emission frequency are defined by the rendering result. In addition, the light emission indicator signal also includes identification information of the light source device 120. Thereby, the lighting control device 110 and the light source device 120 can transmit the light emission indicator signal to the designated light source device based on this identification information.

[0050] Next, the processor 112 can transmit a light emission indicator signal to the corresponding light source device 120 via the communication transceiver 111 (step S1020). Based on the above rendering results, the processor 112 can transmit a light emission indicator signal indicating a specific lighting effect to the corresponding light source device 120 via the communication transceiver 111. After receiving the light emission indicator signal, the light source device 120 enters the rendering mode and can emit the specified spatial lighting effect through its light emission element 123. For the system formed by the host device and the auxiliary devices, the lighting control device 110 can transmit the light emission indicator signal to the host device, and the host device can transmit the light emission indicator signal to its auxiliary devices.

[0051] For example, FIG11 is a schematic diagram of the actual lighting effect in a space according to an embodiment of the present invention. Referring to FIG11, the main unit 120-1 receives the lighting indication signal transmitted by the lighting control device 110 and transmits the corresponding lighting indication signal to the auxiliary devices 120-12 and 120-13 respectively. The main unit 120-2 receives the lighting indication signal transmitted by the lighting control device 110 and transmits the corresponding lighting indication signal to the auxiliary devices 120-21 to 120-23 respectively. The main unit 120-3 does not receive the lighting indication signal. The main unit 120-4 receives the lighting indication signal transmitted by the lighting control device 110 and transmits the corresponding lighting indication signal to the auxiliary device 120-41. The main unit 120-5 receives the lighting indication signal transmitted by the lighting control device 110 and transmits the corresponding lighting indication signal to the auxiliary devices 120-51 to 120-53 respectively.

[0052] Refer to Figures 9A and 11. The lighting effect of the light source devices 120 in Figure 11 (i.e., main devices 120-1, 120-2, 120-4, 120-5 and auxiliary devices 120-11~14, 120-21~120-23, 120-41, 120-51~120-53) corresponds to the rendering result SLE1 in Figure 9A. The light-emitting elements 123 of the light source devices 120 (i.e., main devices 120-1, 120-3, auxiliary devices 120-11, 120-14, 120-31~120-33) that do not receive the corresponding light emission indicator signal are disabled / do not emit light.

[0053] The following describes a first application scenario: The lighting control device 110 and the light source device 120 activate the lighting effect software. The lighting effect software of the lighting control device 110 receives a first user instruction (including a positioning instruction). The lighting effect software of the lighting control device 110 transmits the positioning instruction (i.e., the aforementioned positioning indication signal) to the light source device 120 (e.g., the main devices 120-1 to 120-5 and the corresponding auxiliary devices 120-11 to 120-14, 120-21 to 120-23, 120-31 to 120-33, 120-41, and 120-51 to 120-53 in FIG2). The light source device 120 enters the positioning mode and activates the corresponding positioning lighting effect through its light-emitting element 123.

[0054] Taking Figure 5 as an example, the main unit 120-1 receives the positioning command, enters the positioning mode, and activates the built-in positioning light effect. The main unit 120-1 transmits the positioning command to the corresponding auxiliary units 120-11 to 120-14. The auxiliary units 120-11 to 120-14 receive the positioning command, enter the positioning mode, and activate the built-in positioning light effect.

[0055] The lighting control device 110 receives images captured by the image capturing device 113. The lighting effect software of the lighting control device 110 analyzes the images through image recognition and calculates the number and position of the positioning lighting effects (i.e., positioning information). If the positioning lighting effects are incomplete, they will not be counted.

[0056] Taking Figure 6 as an example, the first positioning light effect is located in the upper left corner, and its quantity is 2; the second positioning light effect is located in the upper right corner, and its quantity is 4; the third positioning light effect is located in the lower right corner, and its quantity is 0; the fourth positioning light effect is located in the lower right corner, and its quantity is 2; the fifth positioning light effect is located in the lower left corner, and its quantity is 4. Next, the lighting effect software of the lighting control device 110 establishes a virtual color space based on the quantity and position of the positioning light effects. This is the virtual color space VCS1 shown in Figure 8.

[0057] The lighting effect software of the lighting control device 110 receives a second user instruction (including instructions for the start and end colors of the gradient effect, or including static or dynamic image files). For the gradient effect, the lighting effect software of the lighting control device 110 generates a corresponding gradient direction based on the instructions for the start and end colors. The lighting effect software of the lighting control device 110 renders the virtual color space based on the instructions for the start and end colors and the corresponding gradient direction or the uploaded image file. See the rendering results SLE1 and SLE2 in Figure 9A or Figure 9B.

[0058] The lighting effect software of the lighting control device 110 generates corresponding lighting effect signals (i.e., light emission indicator signals) based on the number, position, and rendering result of the positioned lighting effects. The lighting effect signals, for example, indicate gradient effects or monochrome effects. The lighting effect software of the lighting control device 110 transmits the lighting effect signals to the corresponding light source device 120. Taking Figure 11 as an example, the first lighting effect signal is transmitted to the host device 120-1 and the corresponding auxiliary devices 120-12 and 120-13. If a corresponding lighting effect signal is received, the host device or auxiliary device activates the corresponding lighting effect. For example, auxiliary devices 120-12 and 120-13 activate the corresponding lighting effect. Thus, the host devices 120-1 to 120-5 and the auxiliary devices 120-11 to 120-53 can be connected in series. If no corresponding lighting effect signal is received, the host device or auxiliary device deactivates the corresponding lighting effect. For example, the main unit 120-1 and auxiliary units 120-11 and 120-14 turn off the corresponding lighting effects.

[0059] It is worth noting that the position of the light source device 120 in the lighting system 1 may change. Figure 12 is a flowchart of position update according to an embodiment of the present invention. Referring to Figure 12, the processor 112 of the lighting control device 110 can determine the position change of the light source device 120 through image recognition (step S1210). Specifically, the image capturing device 113 can capture images at regular intervals or triggered by events, and obtain (real-time) images accordingly. The processor 112 then analyzes the images and positions the light source device 120 or the positioning lighting effect accordingly. If the positioning lighting effect moves or decreases in number at different time points, the processor 112 determines that the position change of the light source device 120 has occurred. If the positioning lighting effect is fixed or the number remains unchanged at different time points, the processor 112 determines that the position change of the light source device 120 has not occurred.

[0060] The processor 112 can update the positioning information based on the position change (step S1220). If a position change is detected, the processor 112 updates the positioning information based on the current position and quantity of the positioning light effect. That is, it updates the position of the light source device 120 in the actual space. Then, in the same step S320, the processor 112 can control the light-emitting element 123 of the light source device 120 based on the updated positioning information.

[0061] The following describes a second application scenario. In addition to the steps in the first application scenario, the lighting effect software of the lighting control device 110 also receives third user commands (including image position monitoring commands). The lighting effect software of the lighting control device 110 receives real-time images captured by the image capturing device 113, and the positioning lighting effect emitted by the light source device 120 is converted into a lighting effect signal. The lighting effect software of the lighting control device 110 activates the position monitoring mode.

[0062] In the location monitoring mode, the lighting effect software of the lighting control device 110 analyzes the real-time image through image recognition and determines whether the real-time image includes the complete light source device 120 in the actual space. If the actual space includes the complete light source device 120, the position of the light source device 120 is continuously updated. If the light source device 120 moves from the first position to the second position, the lighting effect software of the lighting control device 110 updates the positioning information and generates a corresponding lighting effect signal (i.e., a light emission indicator signal).

[0063] For example, FIG13 is a schematic diagram illustrating the light emission effect of the updated position according to an embodiment of the present invention. Referring to FIG11 and FIG13, compared to FIG11, the main device 120-2 and auxiliary device 120-22 in FIG13 have moved to the lower position, and the main device 120-4 and auxiliary device 120-41 have moved to the upper position. Therefore, the lighting effect signals of the main devices 120-2, 120-4 and auxiliary devices 120-22, 120-41 will change. The main devices 120-2, 120-4 and auxiliary devices 120-22, 120-41 receive the updated lighting effect signal and emit the corresponding lighting effect.

[0064] In addition to addressing the overall spatial requirements, the present invention also provides individual lighting control.

[0065] FIG14 is a flowchart of user-instructed illumination according to an embodiment of the present invention. Referring to FIG14, the processor 112 of the lighting control device 110 can receive a user instruction (step S1410). This user instruction instructs the lighting effect of one or more light-emitting elements 123 of one or more light source devices 120. That is, the user instruction directly specifies the lighting effect of the light-emitting elements 123 of the light source device 120.

[0066] The processor 112 may generate one or more light emission indicator signals according to user instructions (step S1420). As explained above, the light emission indicator signals are used to indicate the emission of corresponding lighting effects. The user instructions have associated a specific light-emitting element 123 with a specified lighting effect. That is, the light source device 120 may control its light-emitting element 123 to emit light of a specified color, brightness, and / or color temperature, and / or emit flashing at a specified light emission frequency, according to the light emission indicator signals. The aforementioned light of a specified color, brightness, and / or color temperature and / or flashing at a specified light emission frequency are defined by the user instructions.

[0067] Next, the processor 112 can transmit a light emission indicator signal to the corresponding light source device 120 via the communication transceiver 111 (step S1430). Based on the above rendering results, the processor 112 can transmit a light emission indicator signal indicating a specific lighting effect to the corresponding light source device 120 via the communication transceiver 111. After receiving the light emission indicator signal, the light source device 120 can emit the specified lighting effect through its light-emitting element 123. For the system formed by the host device and the auxiliary devices, the lighting control device 110 can transmit the light emission indicator signal to the host device, and the host device can transmit the light emission indicator signal to its auxiliary devices.

[0068] For example, FIG15 is a schematic diagram of the lighting effect in an actual space according to an embodiment of the present invention. Referring to FIG15, assume that the user instruction specifies that the lighting effect of the main devices 120-1, 120-2, and auxiliary devices 120-13, 120-31, and 120-32 is red, the lighting effect of the auxiliary devices 120-12, 120-14, 120-52, and 120-53 is green, and the lighting effect of the main devices 120-3 and 120-4 is purple. In this way, the main devices 120-1 to 120-5 and the auxiliary devices 120-11 to 120-53 can be connected in series.

[0069] The following describes a third application scenario: the lighting control device 110 and the light source device 120 activate the lighting effect software. The lighting effect software of the lighting control device 110 receives user instructions (including color instructions from the light source device 120). The lighting effect software of the lighting control device 110 generates corresponding lighting effect signals based on the color instructions from the light source device 120. For example, lighting effect signals for the host device and lighting effect signals for the auxiliary devices. The lighting effect software of the lighting control device 110 transmits the lighting effect signals to the corresponding light source device 120. Taking Figure 15 as an example, the lighting effect signals are transmitted to the host devices 120-1 to 120-5 and the auxiliary devices 120-11 to 120-53. If the light source device 120 receives the corresponding lighting effect signal, it activates the corresponding lighting effect. As shown in Figure 15, the host devices 120-1 to 120-5 and the auxiliary devices 120-11 to 120-53 all receive the corresponding lighting effect signals, therefore these devices activate the corresponding lighting effects.

[0070] In addition to addressing the overall spatial integrity, the present invention also provides interactive lighting control.

[0071] Figure 16 is a flowchart of a mobile light emission control according to an embodiment of the present invention. Referring to Figure 16, the processor 112 of the light control device 110 can detect the position of the light source device 120 in the actual space (step S1610). For example, the light source device 120 is a mouse device, and the cursor position corresponds to the position of the mouse device. Therefore, the processor 112 can detect the coordinates of the cursor on the system desktop. Another example is based on the above image recognition positioning.

[0072] The processor 112 can convert the position of the light source device 120 in the actual space into its position in the virtual color space (step S1620). In one embodiment, the coordinate system of the system desktop is the same as the coordinate system of the virtual color space. For example, the coordinates of the cursor on the system desktop are the same as the coordinates of the virtual color space. The processor 112 can convert the position in the actual space corresponding to the coordinates of the system desktop into the coordinates of the virtual color space. For example, the processor 112 directly uses the coordinates of the cursor on the system desktop as the coordinates of the virtual color space.

[0073] In another embodiment, the coordinates between the system desktop coordinate system and the virtual color space coordinate system are converted into an equation. The processor 112 can substitute the coordinates of the cursor on the system desktop into this equation and obtain the coordinates of the virtual color space accordingly.

[0074] In one embodiment, the system desktop is formed by merging the system desktops of multiple display devices. For example, the extended desktop function can be used to merge the system desktops of multiple display devices. The processor 112 can generate a virtual color space proportional to the resolution of the multiple display devices. For example, the pixel coordinates of the display devices correspond to the coordinates of the virtual color space.

[0075] The processor 112 can generate a light emission indicator signal based on the spatial lighting effect corresponding to the position of the light source device 120 in the virtual color space (step S1630). The virtual color space has been rendered by spatial lighting effects. Therefore, any position / coordinate in the virtual color space has a corresponding lighting effect (e.g., light of a specific color, brightness, and / or color temperature, and / or flashing at a specific emission frequency). The light emission indicator signal is used to indicate the lighting effect corresponding to the position / coordinate of the light source device 120.

[0076] Next, the processor 112 transmits a light emission indicator signal to the light source device 120 via the communication transceiver 111 (step S1640). After receiving the light emission indicator signal, the light source device 120 enters the rendering mode and can emit the specified lighting effect through its light-emitting element 123. For the system formed by the host device and the auxiliary device, the lighting control device 110 can transmit the light emission indicator signal to the host device, and the host device can transmit the positioning indicator signal to the light source device 120.

[0077] The following describes a fourth application scenario. Figure 17 is a schematic diagram of a single system application scenario according to an embodiment of the present invention. Referring to Figure 17, take the main unit 120-1 of the lighting system 1-1 and its auxiliary units 120-11 to 120-14 as an example. Among them, auxiliary units 120-11 and 120-12 are display devices, and auxiliary unit 120-13 is a mouse (i.e., the aforementioned light source device 120).

[0078] The lighting control device 110 and the light source device 120 activate the lighting effect software. The lighting effect software of the lighting control device 110 receives user commands. The lighting effect software of the lighting control device 110 reads the resolution specifications of the display devices (i.e., auxiliary devices 120-11, 120-12) connected to the host device 120-1 and the relative positions of the multiple display devices.

[0079] For example, FIG18 is a schematic diagram illustrating cursor movement according to an embodiment of the present invention, and FIG19 is a schematic diagram illustrating virtual space corresponding movement according to an embodiment of the present invention. Referring to FIG18 and FIG19, assume that the resolution of the auxiliary device 120-11 is 1024 pixels × 768 pixels, and the resolution of the auxiliary device 120-12 is 1280 pixels × 1024 pixels. The virtual color space VCS2 includes a merged 1024 coordinate point × 768 coordinate point system desktop DS1 and a 1280 coordinate point × 1024 coordinate point system desktop DS2.

[0080] The lighting effect software of the lighting control device 110 defines the coordinates of the auxiliary device 120-13 in the virtual color space VCS2 as the same as the coordinates of the system desktop. If the cursor C of the auxiliary device 120-13 is at coordinates (512, 384) at the system desktop position P11, then the corresponding position P11 of the auxiliary device 120-13 in the virtual color space VCS2 is also at coordinates (512, 384).

[0081] Assume that the auxiliary device 120-13 moves. The lighting effect software of the lighting control device 110 updates the position of the auxiliary device 120-13 in the virtual color space VCS2 to move from position P11 (coordinates (512, 384)) to position P12 (coordinates (1712, 184)).

[0082] The lighting effect software of the lighting control device 110 receives instructions from a third user (including instructions for the start and end colors of the gradient effect, or including static or dynamic image files). For the gradient effect, the lighting effect software of the lighting control device 110 generates a corresponding gradient direction based on the instructions for the start and end colors. The lighting effect software of the lighting control device 110 renders the virtual color space based on the instructions for the start and end colors and the corresponding gradient direction or the uploaded image file.

[0083] For example, FIG20A is a schematic diagram illustrating the rendering result SLE3 of the gradient effect according to an embodiment of the present invention. Referring to FIG20A, the processor 112 performs gradient rendering on the virtual color space VCS2 according to the starting color SC2, the ending color TC2, and the gradient direction (i.e., from the upper left to the lower right), thereby producing the rendering result SLE3 shown in FIG2.

[0084] In addition, the third user instruction also includes a boundary lighting effect instruction. The boundary lighting effect instruction is used to set the boundary lighting effect of the virtual color space. For example, Figure 20B is a schematic diagram of adding a boundary constraint to Figure 20A. Referring to Figure 20B, the boundary E1 is located at the outermost edge of the virtual color space VCS2.

[0085] Figure 21A is a schematic diagram illustrating the rendering result of a static or dynamic image according to another embodiment of the present invention. Referring to Figure 21A, the lighting effect software of the lighting control device 110 maps the pixel colors of the static or dynamic image to the corresponding positions in the virtual color space VCS2, thereby generating the rendering result SLE4 shown in the figure. It should be noted that dynamic image rendering requires rendering the image frame by frame and updating the color information of the virtual color space VCS2 to achieve dynamic lighting effect changes.

[0086] Figure 21B is a schematic diagram of adding boundary constraints to Figure 21A. Referring to Figure 21B, boundary E2 is located at the outermost edge of the virtual color space VCS2.

[0087] Figure 22 is a schematic diagram illustrating the linkage between the actual space and the virtual color space according to an embodiment of the present invention. Referring to Figure 22, the lighting effect software of the lighting control device 110 generates a corresponding lighting effect signal (i.e., a light emission indicator signal) based on the position of the auxiliary device 120-13 in the virtual color space VCS2. For example, if the coordinates of the position P31 of the auxiliary device 120-13 in the virtual color space VCS2 are (512, 384), a lighting effect signal corresponding to this coordinate is generated. The lighting effect signal, for example, indicates a gradient effect or a monochrome effect. The auxiliary device 120-13 receives the lighting effect signal and activates the corresponding lighting effect.

[0088] In one embodiment, when the converted position is located at or beyond the boundary of the virtual color space, the processor 112 of the lighting control device 110 can generate a light emission indicator signal to indicate a boundary warning lighting effect. Taking FIG22 as an example, when the position P32 of the auxiliary device 120-13 in the virtual color space VCS2 (its coordinates are (2400, 200)) is located at the boundary E1 (e.g., (2304, 200)), the lighting effect software of the lighting control device 110 maintains the corresponding coordinates of the auxiliary device 120-13 in the virtual color space VCS2 at the coordinate value of the boundary E1 (e.g., 2304) and emits a boundary lighting effect signal (e.g., red). The auxiliary device 120-13 receives the boundary lighting effect signal and turns on the corresponding lighting effect.

[0089] When the auxiliary device 120-13 moves from position P32 to position P33 (with coordinates (2303, 384)), the lighting effect software of the lighting control device 110 updates the corresponding coordinate value of position P32 to 2303. Furthermore, the lighting effect software of the lighting control device 110 generates a lighting effect signal corresponding to this coordinate. The lighting effect signal, for example, indicates a gradient effect or a single-color effect. The auxiliary device 120-13 receives the lighting effect signal and activates the corresponding lighting effect.

[0090] The lighting effect software of the lighting control device 110 will analyze the position of the auxiliary device 120-13 at any time. Assuming that the auxiliary device 120-13 moves from the third position to the fourth position, a corresponding lighting effect signal will be generated based on the corresponding coordinates of this fourth position and the virtual color space.

[0091] In summary, in the lighting effect control method and lighting control device of the present invention, multiple light source devices with lighting effect functions are connected in series via wireless or wired communication to form a lighting effect system. Through image recognition technology, the lighting effect characteristics of the light source devices in the image are analyzed, and the positions of the corresponding light source devices are mapped to a virtual space. The light-emitting elements of the light source devices connected in the virtual space are linked to the lighting effects at corresponding positions in the virtual space. This provides a more convenient, more accurate, and more interactive lighting effect experience.
