Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional Chroma key compositing equipment and post-production techniques are used, then high-quality Chroma key composites can be achieved, but the process becomes time-consuming and expensive
Solution Approach 1:
The system performs lighting correction and background replacement in real-time during the capture process rather than requiring post-production editing. The processor automatically adjusts lighting parameters and composites backgrounds as the video is being recorded, eliminating the need for time-consuming post-production techniques while maintaining high composite quality.
Solution Approach 2:
The patent replaces traditional mechanical studio equipment with a portable system that uses software-based processing on a smart device. Instead of requiring physical lighting adjustments and manual post-production work, the system uses automated digital processing to achieve Chroma key compositing, significantly reducing time and cost requirements.
2Stability of the object's composition
If traditional Chroma key compositing equipment is used, then uniform lighting can be achieved, but the device complexity and space requirements increase
Solution Approach 1:
The smart device serves multiple functions: it captures the video, processes the Chroma key compositing, adjusts lighting parameters, and displays the result. This multi-functionality eliminates the need for separate traditional Chroma key equipment, reducing overall device complexity while maintaining lighting uniformity through integrated processing capabilities.
Solution Approach 2:
The system creates a digital copy of the background and subject, then processes these digital representations through software algorithms to achieve uniform lighting and perfect compositing. This digital approach replaces physical lighting equipment and manual adjustments, simplifying the overall system while maintaining quality.
3Reliability
If traditional Chroma key compositing is used, then color neutrality can be ensured, but the cost and equipment requirements place a burden on consumers
Solution Approach 1:
The system performs self-service processing by automatically detecting the monochromatic background, adjusting lighting parameters, and compositing the background replacement without requiring manual intervention. This automation maintains color neutrality and high composite quality while making the technology accessible to consumers who do not need expensive traditional equipment.

AI summary
A system and, related method, is disclosed for enabling Chroma key compositing using a smart device, wherein an image/video of a subject situated in front of a portable monochromatic background is captured, and simultaneously layered upon a different desired background replacement that will replace only the monochromatic background captured. The portable monochromatic background structure can be a three-dimensional lighting structure affixed with a plurality of lighting modules configured to ensure a uniform light distribution across the monochromatic background and separately to ensure a uniform light distribution on the subject during the image/video capture. Moreover, a software application on a smart device can act as a system platform that enables for automatic processing of pixel correction in the monochromatic background during the Chroma key process in real-time, and light adjustment of the lighting modules on a portable monochromatic background to correct any light imperfections that impede color neutrality on the background.
