Solution Overview
Problem
Existing systems struggle to render visually pleasing light effects with pixelated lighting devices when the devices are too far apart, leading to unrelated light effects, especially in dynamic scenarios where motion and environmental interactions are involved.
Innovation Solution
A system and method that select a set of lighting devices based on distance information and environmental parameters to ensure they are close enough to render cohesive light effects, using a processor to control only the selected devices and adjust light effect parameters dynamically.

1Area of stationary object
If multiple lighting devices are used to render light effects, then the coverage area and visual impact are improved, but the devices may appear to render unrelated light effects when they are too far apart
Solution Approach 1:
The system dynamically selects lighting devices based on real-time distance calculations and effect parameters. The processor determines which devices are suitable for rendering a specific light effect by evaluating their spatial relationships, enabling the system to adapt to different coverage requirements while maintaining visual coherence through distance-based selection criteria
Solution Approach 2:
The patent applies different selection criteria to different spatial groups of lighting devices. By evaluating distances between individual devices and the rendering location, the system ensures that each selected device meets local coherence requirements for its specific position, allowing heterogeneous device characteristics while maintaining overall visual consistency
2Reliability
If lighting devices are selected based on proximity to ensure visual coherence, then the naturalness and pleasing quality of light effects are improved, but the coverage area may be limited
Solution Approach 1:
The system dynamically adjusts the selection of lighting devices based on the specific light effect being rendered and the spatial configuration. By calculating distances between devices and the rendering location in real-time, the system can expand or contract the selected device group to achieve optimal visual coherence while maximizing coverage area for each effect type
Solution Approach 2:
The patent creates a universal selection mechanism that can adapt to different light effect types and spatial configurations. The distance-based selection criteria serve multiple functions: ensuring visual coherence, determining coverage area, and selecting appropriate devices for various effect categories, making the system versatile across different rendering scenarios
3Reliability
If distance information is obtained and processing is performed to select appropriate lighting devices, then the naturalness of light effects is improved, but the system complexity increases
Solution Approach 1:
The system automatically obtains distance information and performs selection processing without requiring manual intervention. The processor autonomously evaluates spatial relationships, determines suitable lighting devices, and configures the rendering system, reducing the need for complex user configuration while maintaining natural light effect quality
Solution Approach 2:
The system uses distance information as feedback to continuously optimize device selection. By evaluating the spatial relationships between lighting devices and the rendering location, the system adjusts its selections to maintain natural visual quality, creating a closed-loop control mechanism that improves naturalness without requiring overly complex manual systems
