Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing background playback devices for virtual image capture studios have fixed beam characteristics that limit creative freedom and often require extensive post-processing due to their inability to adapt to different shooting situations.
Innovation Solution
A background playback device with an active illumination device and a controllable lens arrangement that modifies the beam characteristics of pixel elements, allowing for adjustable and variable lighting to suit specific shooting conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed beam characteristic display device is used, then the device structure is simple, but the adaptability to different shooting situations is poor
Solution Approach 1:
The patent applies the dynamics principle by making the beam characteristics of the pixel elements dynamically adjustable through a controllable lens arrangement. Each pixel element can independently modify its beam width and direction in real-time based on shooting requirements, transforming a static display system into a dynamic one that adapts to various recording scenarios without requiring complex structural changes.
Solution Approach 2:
The patent implements parameter changes by enabling continuous adjustment of beam width and direction parameters for each pixel element through the lens arrangement. This allows the display device to modify its optical characteristics on-the-fly, adapting to different shooting situations by changing beam parameters rather than requiring physical reconfiguration or multiple fixed-configuration devices.
2Adaptability or versatility
If post-processing is performed to adjust lighting, then the adaptability improves, but the loss of time increases
Solution Approach 1:
The patent applies preliminary action by enabling lighting and beam characteristic adjustments to be made in real-time during the recording process itself, rather than requiring post-processing. The controllable lens arrangement allows beam width and direction to be optimized before and during capture, eliminating the need for time-consuming post-processing adjustments and allowing immediate visualization of the final lighting效果.
3Adaptability or versatility
If the beam characteristics are fixed, then the manufacturing precision is easier to maintain, but the creative freedom is limited
Solution Approach 1:
The patent implements universality by designing a single display device that can perform multiple lighting functions through the controllable lens arrangement. The same pixel elements can produce different beam characteristics (narrow/focused or wide/diffused) based on shooting requirements, making one device replace multiple specialized lighting devices and expanding creative possibilities without proportionally increasing system complexity.
