Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current digital video cameras, especially those in smartphones, capture low-quality video and still images, and existing techniques for background replacement in video are limited, making it difficult to achieve high-quality photographs and videos.
Innovation Solution
A video photography system that includes a video camera and a background lighting system capable of generating distinguishable lighting conditions, allowing for high-quality image capture and automated background replacement using a sequence of lighting conditions and audio encoding for photographer intent.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If digital video cameras are used for photograph capture, then portability and ease of operation are improved, but image quality deteriorates
Solution Approach 1:
The system segments the photography process into multiple sequential photographs captured at different time points. Instead of relying on a single photograph from a video camera, the system captures a series of images and selects the best one, thereby improving image quality while maintaining the ease of operation of digital video cameras.
Solution Approach 2:
The system performs preliminary actions by capturing multiple photographs in sequence before final selection. This preliminary capture of multiple images allows the system to pre-process and evaluate different frames, ensuring high quality output while using the convenient digital video camera platform.
2Manufacturing precision
If multiple photographs are captured to select the best facial expression, then photograph quality is improved, but time consumption increases
Solution Approach 1:
The system implements periodic action by capturing photographs at regular time intervals automatically. This periodic capture continues for a predetermined duration, eliminating the need for manual timing and reducing the time required to capture multiple expressions while ensuring high photograph quality through automated selection.
Solution Approach 2:
The system performs self-service by automatically selecting the best photograph from the captured sequence based on predetermined criteria such as facial expression quality. This automated selection process eliminates manual review time and quickly identifies the optimal image, reducing overall time consumption while maintaining high photograph quality.
3Adaptability or versatility
If background replacement techniques are applied to video, then background flexibility is improved, but image quality deteriorates due to chroma key limitations
Solution Approach 1:
The system performs preliminary background replacement on individual photographs before assembling them into video. By replacing backgrounds in the still image domain using high-quality techniques rather than video chroma key, the system achieves both background flexibility and high image quality, then combines these processed images into the final video output.

AI summary
A video photography system includes a video camera system and a background lighting system. The video camera system is configured to capture photographs of a subject positioned between the video camera system and a background. The background lighting system is configured to generate background lighting conditions on the background. The background lighting conditions include at least a first lighting condition and a second lighting condition.
