Projection Color Adjustment for Non-White Surfaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional projection devices have a single projection mode that cannot be adjusted according to different environments, leading to poor projection effects when projecting onto walls with non-white colors, such as light blue or light yellow, or wallpaper patterns.
Innovation Solution
An information processing method and electronic device that collect image information of the projection plane, acquire color information, generate a color adjusting template, and perform color adjustments on projection images to match the projection plane's color, thereby improving the projection effect by minimizing the difference between the original and projected image colors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single projection mode is used, then the device complexity is low, but the adaptability to different projection environments is poor
Solution Approach 1:
The projection device dynamically adjusts projection parameters including color temperature, saturation, and brightness based on real-time detection of the projection plane's characteristics. The system transitions from a static single-mode projection to a dynamic multi-mode projection that adapts to different environments such as white walls, colored walls, and patterned surfaces.
Solution Approach 2:
The system changes projection parameters such as color temperature, saturation, and brightness levels according to the detected projection plane characteristics. By adjusting these parameters, the device can optimize projection quality for different background colors and patterns without requiring multiple physical projection modes.
2Manufacturing precision
If projection images are not adjusted according to projection plane color, then the processing simplicity is high, but the projection effect is poor on non-white surfaces
Solution Approach 1:
The system incorporates a feedback mechanism where the projection plane is detected first, then the detected color information is fed back to adjust the projection images. This closed-loop process ensures that projection color accuracy is optimized based on actual plane characteristics while managing processing complexity through automated detection and adjustment.
Solution Approach 2:
The system performs preliminary detection of the projection plane's color and pattern characteristics before projecting the actual content. This preliminary action allows the system to pre-adjust projection parameters and generate optimized projection images in advance, improving color accuracy without adding significant processing complexity during the actual projection.
3Manufacturing precision
If color adjustment template is applied, then the projection color matching is improved, but the processing time increases
Solution Approach 1:
The color adjustment template is generated in advance based on the detected projection plane characteristics, before the actual projection occurs. This preliminary generation of the adjustment template allows for faster processing during projection, as the system only needs to apply the pre-computed template rather than calculating adjustments in real-time.
Solution Approach 2:
The system applies color adjustment selectively to the extent necessary to achieve acceptable color matching, rather than applying maximum adjustment in all cases. By using partial action based on the detected plane characteristics, the system balances color matching precision with processing time requirements.
