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

VSEngineering 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

Engineering Contradiction:
Improvecoverage area of lighting effectVSAvoidaccuracy of atmosphere rendering
Core Design Contradiction:
Area of stationary objectVSMeasurement precision

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.

Inventive Principle:
Principle #1Segmentation

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

Engineering Contradiction:
Improveaccuracy of lighting effectVSAvoidcomplexity of control system
Core Design Contradiction:
Measurement precisionVSDevice complexity

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.

Inventive Principle:
Principle #1Segmentation

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.

Inventive Principle:
Principle #3Local quality

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

Engineering Contradiction:
Improvedelicacy of lighting effectVSAvoidprocessing time
Core Design Contradiction:
Measurement precisionVSLoss of time

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.

Inventive Principle:
Principle #1Segmentation

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.

Inventive Principle:
Principle #16Partial or excessive action
