Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional Chroma key compositing equipment and post-production techniques are used, then color neutrality and quality of the composite are improved, but device complexity, time consumption, and cost increase
Solution Approach 1:
The patent combines the monochromatic background and lighting modules into a single integrated portable structure, eliminating the need for separate traditional Chroma key equipment. The lighting modules are built into the background structure itself, merging multiple functions into one device that achieves color neutrality without requiring extensive external equipment.
Solution Approach 2:
The portable Chroma key structure includes built-in lighting modules that automatically illuminate the monochromatic background, making the system self-sufficient. The processor automatically adjusts lighting to correct imperfections, eliminating the need for external post-production techniques and manual equipment setup.
2Manufacturing precision
If traditional Chroma key compositing equipment is used, then color neutrality is improved, but loss of time increases due to post-production processes
Solution Approach 1:
The lighting modules are pre-installed on the portable Chroma key structure and automatically activate during recording. The processor continuously monitors and adjusts lighting in real-time to maintain color neutrality, eliminating the need for time-consuming post-production corrections.
Solution Approach 2:
The system performs lighting correction continuously during the entire recording process rather than requiring separate post-production steps. The processor continuously adjusts the lighting modules to compensate for environmental variations, maintaining color neutrality throughout the capture process without interruption.
3Illumination intensity
If sufficient lighting equipment is used to ensure uniform light distribution, then color neutrality is improved, but device complexity and portability decrease
Solution Approach 1:
The lighting modules are integrated directly into the portable Chroma key structure, combining illumination functionality with the background itself. This integration provides uniform light distribution across the monochromatic surface while maintaining a compact, portable design that does not require separate lighting 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
