Ambient Lighting Frame Segmentation for Accurate Color Atmosphere
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Ambient lamps struggle to accurately simulate lighting effects due to complex color distributions in environmental images, leading to inaccurate atmosphere rendering and reduced effectiveness in shaping the desired ambiance.
Innovation Solution
The ambient lighting device divides the display frame into multiple unit frames and environmental reference images, determining the lighting color value for each unit frame based on the main color tone of the regional image, ensuring each lamp bead emits the appropriate color to simulate the overall lighting effect of the environmental reference image.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the ambient lamp uses the overall color distribution of the environmental image to determine lighting effect, then the lighting effect can cover the entire image, but the complex color distribution in the image will mislead the determination and reduce accuracy of atmosphere rendering
Solution Approach 1:
The patent divides the environmental image into multiple regional images and the display frame into multiple unit frames. Each unit frame corresponds to a regional image, and the lighting color value is determined separately for each unit frame based on its corresponding regional image. This segmentation approach allows the system to handle complex color distributions by processing smaller, more manageable regions independently, thereby maintaining accuracy while achieving overall coverage.
2Measurement precision
If the ambient lamp divides the display frame into multiple unit frames and determines lighting color value for each unit frame separately, then the lighting effect accuracy is improved, but the device complexity increases
Solution Approach 1:
The patent divides the display frame into multiple unit frames and processes each unit frame independently. This segmentation allows the control system to handle complex color distributions by processing smaller regions separately, which improves accuracy while managing computational complexity through modular processing.
Solution Approach 2:
The patent applies different lighting color values to different unit frames based on the local color characteristics of corresponding regional images. Each unit frame's lighting effect is optimized for its specific region, allowing the system to achieve high accuracy in representing local color variations without requiring uniform complex processing across the entire display frame.
3Measurement precision
If the ambient lamp uses fine granularity unit frames to simulate lighting color distribution, then the lighting atmosphere effect is enhanced, but the processing time and computational load increase
Solution Approach 1:
The patent divides the display frame into multiple unit frames that can be processed in parallel. This segmentation into manageable units allows for finer granularity in lighting effect simulation while enabling parallel processing, which reduces the overall processing time compared to handling the entire image as a single unit.
Solution Approach 2:
The patent processes each unit frame independently with the necessary level of detail, rather than applying excessive processing to the entire image. This approach achieves delicate lighting effects in each region while avoiding the computational overhead of processing every pixel at maximum detail across the whole display frame.
