Description

Technical Field

[0001] This invention relates to the technical field of ambient lighting, and in particular to an ambient lighting control method, device, terminal, and storage medium based on parameter fusion. Background Technology

[0002] With the increasing popularity of home entertainment devices, users are demanding more immersive ambient lighting when watching TV, movies, or playing games. Existing screen-synchronized ambient lighting systems typically achieve dynamic synchronization between the screen and the lighting by reading the pixel color information of the screen image and mapping the color results onto light strips or lamps. These solutions mostly employ methods such as regional color sampling, mean color sampling, and dominant color extraction, which can enhance the viewing experience to some extent.

[0003] However, existing technologies generally have the following shortcomings: Currently, most screen-synchronized lighting systems rely solely on screen color data for lighting control, without considering the actual lighting conditions of the user's environment. For example, in bright environments, the light brightness and color strictly follow the screen output, which may cause discomfort such as dim lighting or sudden changes in brightness.

[0004] Without considering audio factors, existing technologies do not respond adequately to changes in content. They typically do not use volume, sound field changes, or rhythm information as the basis for light adjustment, making it difficult for light to coordinate with sound. This is especially true in high-dynamic content scenes such as music and action movies, where light feedback appears lagging or lacks rhythm.

[0005] The lighting effects are limited and cannot adapt to different content types. Because they rely solely on the color picker from the screen, the existing lighting brightness and color temperature changes often appear abrupt and fluctuate significantly. They lack comprehensive consideration of factors such as ambient light, sound intensity, and user scenarios, making it difficult to achieve smooth and intelligent lighting transitions.

[0006] Therefore, existing technologies cannot be optimized in conjunction with changes in ambient light, volume, and different lighting effects, resulting in insufficient matching between lighting performance and the actual viewing scene, and limited immersion.

[0007] Therefore, there is an urgent need for an intelligent dimming control method that can integrate screen color sampling, ambient light parameters, volume information, and lighting effect modes to achieve a more natural, comfortable, and immersive ambient lighting effect.

[0026] This embodiment provides a method for controlling an ambient light based on parameter fusion. The parameter fusion refers to comprehensively processing various parameters from different sources and having different physical meanings to generate unified light effect control parameters. The method can be applied to a television, a set-top box, a display terminal, or an ambient light system配套 with a display device, and comprehensively controls the brightness, color, and dynamic effect of the ambient light by fusing ambient light parameters, audio parameters, and video parameters.

[0027] In this embodiment, the method includes the following process.

[0028] First, multi-source parameters are collected.

[0029] The illuminance data of the user's environment is obtained through an ambient light acquisition module. The illuminance data is usually collected by an ambient light sensor and represented by lux values, which is used to reflect the brightness condition of the user's environment. At the same time, the audio signal corresponding to the currently played content is obtained through an audio interface, and the video signal corresponding to the currently displayed content is obtained through a video interface.

[0030] In one implementation, the ambient light illuminance data is a real-time collected lux value. To avoid sudden changes in ambient light over a short period of time from causing abrupt effects on the ambient light control, the lux value is first subjected to time smoothing before subsequent processing to obtain a smoothed ambient light value lux_smooth. The time smoothing process is used to reduce the impact of instantaneous changes on the control results.

[0031] Secondly, the collected parameters are preprocessed.

[0032] For ambient light parameters, `lux_smooth` is mapped to an ambient light coefficient `envFactor` according to a preset ambient light mapping function. This ambient light mapping function describes the correspondence between ambient light and the output brightness or saturation of the ambient light. In one embodiment, the ambient light mapping function is a logarithmic or linear mapping, and `lux_smooth` is limited to a preset range before mapping to avoid extreme lighting conditions from having an abnormal impact on the lighting effect. The `envFactor` is used to characterize the adjustment weight of ambient light conditions on the lighting effect during parameter fusion.

[0033] For video parameters, the video image is sampled by a screen color acquisition module to extract color information from multiple screen sampling points. These screen sampling points refer to pixel regions or locations selected within the displayed image to reflect the overall color distribution characteristics. In one embodiment, the screen sampling points include at least eight screen edge points and one screen center point. Based on the color information from these sampling points, a base color parameter `baseHsv` is generated to represent the dominant color characteristics of the current image. `baseHsv` is generated based on the HSV color space and includes hue, saturation, and brightness components.

[0034] In one implementation, to avoid frequent color jumps in the ambient light due to rapid changes in screen colors, the hue component in the basic color parameters undergoes smoothing processing over time. This smoothing process employs an exponentially weighted moving average algorithm that considers the hue angle rotation characteristics to ensure continuity of hue as it changes between 0° and 360°, resulting in a more natural transition in the ambient light color.

[0035] For audio parameters, the audio signal is analyzed by the volume feature extraction module to extract the volume feature volumeNorm, which reflects the current change in sound intensity. The volumeNorm is a normalized volume parameter used to characterize the relative amplitude of the change in the intensity of the audio signal.

[0036] Then, the parameters are merged to generate lighting effect control parameters.

[0037] The lighting effect parameter fusion module performs comprehensive calculations on the color, brightness, and dynamic effect parameters of the ambient light based on the base color parameter baseHsv, the ambient brightness coefficient envFactor, and the volume feature volumeNorm, generating lighting effect parameters LightParams, where LightParams is a set of parameters describing the current output state of the ambient light.

[0038] In one implementation, the LightParams also includes a pulse parameter, which describes the dynamic change characteristics of the lighting effect and can be used to control the dynamic lighting behavior of the ambient light, such as the flashing frequency, breathing amplitude, or running speed of the light strip, so that the lighting effect can be linked with the audio rhythm or visual changes.

[0039] Finally, the ambient lighting is controlled based on the generated control parameters.

[0040] The communication and firmware interface module converts the LightParams into ambient light control commands and sends them to the LED control firmware. The LED control firmware is a control program running on the lighting control chip, used to parse the control commands and drive the LED beads to emit light according to specified colors, brightness, and dynamic effects. Based on the control commands, the LED control firmware performs real-time control of the ambient light's brightness, color, and dynamic lighting effects.

[0041] Through the above method, this embodiment can comprehensively adjust the ambient light under the combined effects of changes in screen content, ambient light, and volume, so that the ambient light presents a more natural, harmonious, and immersive lighting effect in different viewing scenarios, thereby solving the problem that existing ambient light systems rely on a single parameter for control and lack immersion.
