[0031] MAIN ELEMENT SYMBOL EXPLANATION
[0032]
[0033] The following detailed description will further describe the present application with reference to the above-mentioned accompanying drawings. DETAILED DESCRIPTION
[0034] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of the present application.
[0035] The term “and / or” in the present application is a description of the association relationship of the associated objects, which means that there can be three relationships, for example, A and / or B can mean that A exists alone, A and B exist together, and B exists alone. In this paper, the symbol “ / ” represents the relationship of or, for example, A / B represents A or B.
[0036] In the description of the embodiments of the present application, the words “exemplary” or “for example” are used to mean serving as an example, instance, or illustration. Any embodiment or design solution described as “exemplary” or “for example” in the embodiments of the present application should not be interpreted as being more preferred or having more advantages than other embodiments or design solutions. Rather, the use of “exemplary” or “for example” is intended to present relevant concepts in a concrete manner.
[0037] With the development of light technology, people's requirements for the diversification of light effects are getting higher and higher. The light effect refers to the light effect presented by light by adjusting the parameters of light. The most common light effect rendering control method is to control the change of the RGB value of light. The RGB value of light refers to the brightness value corresponding to the color of light. The color of the lamp tube includes red (R), green (G) and blue (B), and the specified color is obtained by mixing the three colors of red, green and blue in different proportions. By controlling the RGB value of the light, the superposition of color light, color mixing, saturation and brightness can be adjusted, so as to present different light effects.
[0038] At the program execution level, the light effect rendering control method is implemented through a light effect rendering control function, which is stored in the Flash (Flash Memory) of the light strip controller. When the light strip needs to emit light according to the specified light effect, the light strip controller calls the light effect rendering control function from the Flash and loads it for execution in the RAM (Random Access Memory).
[0039] However, due to the limitation of the flash code storage capacity, it is difficult to store enough light effect rendering control functions, and therefore, the number of light effects supported by the light strip controller is small and the style is monotonous, which is difficult to meet the user's use demand, resulting in poor user experience.
[0040] To this end, the embodiment of the present application provides a light effect rendering method and device, a light emitting device and a computer storage medium, which can reduce the occupation of light effect rendering control functions to the flash code storage capacity, support more light effect rendering control functions, provide more diversified light effects, and improve the user experience.
[0041] Please refer to Figure 1 , which shows the structure schematic diagram of the light emitting device provided by the embodiment of the present application.
[0042] The light emitting device includes a light emitting part 1 and a light strip control terminal 2. The light emitting part 1 is electrically connected to the light strip control terminal 2, for example, through a cable.
[0043] In a specific embodiment, the light emitting part 1 can be a light strip, a display screen or other electronic devices. The light emitting part 1 includes a plurality of light emitting elements, each of which can independently emit light of different colors.
[0044] In a specific embodiment, the light strip control terminal 2 is used to control the plurality of light emitting elements in the light emitting part 1 to emit light according to the specified RGB value at the specified time point when the specified light effect rendering function is loaded, so as to perform light effect rendering and obtain the corresponding light effect.
[0045] Specifically, the light strip control terminal 2 can store data information through Flash, and import and deliver the data information when needed.
[0046] In the embodiment, the light effect rendering function is divided into two parts. One part is the execution environment information, which is the necessary data information for executing the light effect rendering function, for example, local variables, the pointer table first address of the light attribute function, the color selection table first address of the color selection table and the memory space address with global attributes, etc. The execution environment information is stored in the Flash. The other part is the light effect control information, which is the data information for actually controlling the light effect change by changing the corresponding parameters of the light emitting part 1, for example, the RGB value of the light emitting element at the specified time point. The light effect control information is stored in other storage devices of the Flash other than the light strip control terminal 2, such as hardware storage devices, cloud servers, etc.
[0047] When the light strip control terminal 2 needs to control the light emitting part 1 to emit light according to the specified light effect, the light effect control terminal needs to first obtain the light effect control information corresponding to the light effect, then call the light effect control information to load in the RAM, and pass the execution environment information during the loading process to provide a plug-in execution environment for the light effect rendering function, and then control the light emitting part 1 to emit light according to the specified light effect.
[0048] The above technical solution reduces the occupation of the light effect control information to the Flash code storage capacity, and at the same time liberates the limitation of the Flash code storage capacity to the light effect control information, so as to provide sufficient light effect control information for the light strip control terminal 2 to use, so that the light emitting device can support more diversified light rendering effects, and improve the user experience.
[0049] Please refer to Figure 2 , which shows the connection schematic diagram of the light emitting device and the user terminal 3 provided by an embodiment of the present application.
[0050] The user terminal 3 is in communication connection with the light emitting device. The user terminal 3 is in communication connection with the light strip control terminal 2. The user terminal 3 is used to obtain the light effect control information and send it to the light strip control terminal 2. The communication connection between the user terminal 3 and the light strip control terminal 2 can be in the form of Bluetooth connection, WIFI connection, local area network connection, network connection, etc.
[0051] In the embodiment, the light effect control information is stored in the light effect database in the form of a bin file, and the light effect database is a cloud server database. The user terminal 3 downloads the light effect control information from the light effect database and sends it to the light strip control terminal 2.
[0052] Specifically, the user terminal 3 has an operation page, and a plurality of light effect preview icons are displayed in the operation page. The icon can be a dynamic icon. Each light effect preview icon corresponds to a light effect control information, and the light effect preview icon is used to show the preview effect of the light effect corresponding to the light effect control information. The user can view the corresponding light effect through the light effect preview icon in the operation page.
[0053] When the user selects the corresponding light effect preview icon in the operation page, i.e. touches the light effect preview icon or presses the specified key, the user terminal 3 detects the light effect trigger operation of the operation page. The user terminal 3 will download the corresponding light effect control information in response to the light effect trigger operation of the operation page, and send the light effect control information to the light strip control terminal 2 to control the light emitting part 1 to emit light according to the specified light effect.
[0054] In a specific embodiment, the data in the light effect database can be updated. The light effect designer or developer can add light effect control information to the light effect database, or update or upgrade the light effect control information in the light effect database by uploading light effect control information to the light effect database, thereby updating the light effects supported by the light strip control terminal 2.
[0055] It can be understood that the user terminal 3 includes but is not limited to a mobile phone, a tablet computer, a desktop computer, a laptop computer, a handheld computer, a notebook computer, an ultra-mobile personal computer (UMPC), a netbook, and a cellular phone, a personal digital assistant (PDA), an augmented reality (AR) device, a virtual reality (VR) device, an artificial intelligence (AI) device, a wearable device, an in-vehicle device, a smart home device, and / or a smart city device, and the present embodiment does not make special limitations thereto.
[0056] Please refer to Figure 3 , which shows a flowchart of the light effect rendering method provided by the present embodiment.
[0057] The light effect rendering method can be applied to the light strip control terminal 2 described in any of the above embodiments, and the light strip control terminal 2 can implement the light effect rendering method by executing pre-stored executable instructions. The light effect rendering method includes the following steps.
[0058] S301, acquiring light effect control information.
[0059] The light effect control information is a light effect rendering control function file, and the light effect control information is used to indicate the light emitting parameters of the light emitting piece 1. The light emitting parameters include the RGB values of the light emitting piece 1 in a preset time sequence, and the time sequence is composed of a plurality of time points.
[0060] In the present embodiment, the light effect control information is information sent by the user terminal 3 to the light strip control terminal 2 in response to a light effect triggering operation.
[0061] S302, loading the light effect control information and importing pre-stored execution environment information.
[0062] The light strip control terminal 2 calls the light effect control information, loads and executes it in the RAM, and passes the execution environment information pre-stored in the Flash to provide a plug-in execution environment for the light effect control information, thereby controlling the light emitting piece 1 to emit light according to the light emitting parameters.
[0063] In the embodiment, the execution environment information includes function data information necessary for executing the lamp effect control information.
[0064] Please refer to Figure 4 In one embodiment, the execution environment information includes pre-declared local variables, a pointer table first address of a light attribute function, and a color table first address of a color table.
[0065] The light attribute function is a pre-set API function, such as a lamp control data refreshing function, a lamp control timing function, etc. The light attribute function is stored in the pointer. When the lamp effect control information is loaded and executed, the imported pointer table first address is passed to obtain the corresponding light attribute function, so that the light emitting member 1 can work normally.
[0066] The color table stores rich RGB values. When the lamp effect control information is loaded and executed, the imported color table first address of the color table is passed to obtain the RGB values in the color table, so that the light emitting member 1 can emit light according to the specified RGB values.
[0067] For example, the code of the execution environment information can be:
[0068] void Render_Func(uint* api_table_ptr,Color* color_table,uint)
[0069] The api_table is the pointer table first address, and the color_table is the color table first address.
[0070] It can be understood that the step S302 specifically comprises: loading the lamp effect control information, and importing the pre-stored local variables, the pointer table first address, and the color table first address.
[0071] Please refer to Figure 5 In another embodiment, in addition to the pre-declared local variables, the pointer table first address of the light attribute function, and the color table first address of the color table, the execution environment information also includes a memory space address with global attributes. The memory space address is used to indicate the state quantity of the historical lamp effect rendering. The storage unit corresponding to the memory space address saves the state quantity in the last rendering process.
[0072] Since the memory space address has global attributes, after each lamp effect rendering is completed, the memory space address will not be automatically erased after the point is dropped, thereby retaining the state quantity before the lamp effect rendering is completed. When the next lamp effect rendering starts, the memory space address can be used to pass the state quantity or rendering control parameter in the last rendering process, so that the lamp effect rendering can be continued according to the progress of the last lamp effect rendering.
[0073] For example, the code of the execution environment information can be:
[0074] void Render_Func(uint* api_table_ptr,Color* color_table,uint* global_mem)
[0075] Wherein, the api_table is the pointer table address, the color_table is the color table address, and the global_mem is the memory space address.
[0076] It can be understood that the step S302 specifically comprises: loading the light effect control information, and importing the pre-stored local variable, the pointer table address, the color table address and the memory space address.
[0077] Please refer to Figure 6 In a specific embodiment, the light effect rendering method further comprises the following steps.
[0078] S601, the user terminal 3 responds to the light effect trigger operation of the user interface, downloads the light effect control information and sends it to the light strip control terminal 2.
[0079] Specifically, the user terminal 3 downloads the light effect control information from the updatable light effect database.
[0080] Please refer to Figure 7 and Figure 8 In a specific embodiment, the light effect rendering method further comprises the following steps.
[0081] S701, get the link script.
[0082] Wherein, the link script is associated with the light effect control information, and the link script is used to plug-in the light effect control information. The link script can be a scat file or an lds file.
[0083] S702, compile the link script to determine the execution address of the light effect control information in the memory.
[0084] Wherein, in the linking stage, the link script is compiled by the compiler to compile the C File class file into the BIN File class file, and the execution address of the light effect control information is linked to a fixed address within the RAM space range of the light strip control terminal 2. The light strip control terminal 2 loads and executes at the fixed address when loading the light effect control information.
[0085] After step Sb02, the light strip control terminal 2 will prohibit other programs from occupying the fixed address, thereby reserving a certain amount of execution memory space for the light effect control information to be loaded.
