Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing imaging technologies struggle to effectively reduce atmospheric fluctuation-induced image degradation while minimizing blur in moving objects, particularly in monitoring applications like harbor surveillance and aircraft photography.
Innovation Solution
An imaging apparatus that determines exposure time based on fluctuation amount and correction intensity, using a processor to control shutter speed and perform image processing to reduce fluctuation while suppressing moving object blur.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If image smoothing is performed in the time direction to reduce atmospheric fluctuation, then image stability is improved, but moving objects become blurred
Solution Approach 1:
The patent applies dynamics by making the exposure time adjustable rather than fixed. The determination unit dynamically selects between first exposure time (shorter) and second exposure time (longer) based on real-time fluctuation amount detection, allowing the system to adapt to changing atmospheric conditions while maintaining sharp moving objects during stable periods
Solution Approach 2:
The patent changes the exposure time parameter based on detected fluctuation conditions. When fluctuation amount exceeds a threshold, the system switches to longer exposure time to reduce atmospheric interference; when fluctuation is low, it uses shorter exposure time to maintain object sharpness, thereby resolving the contradiction between image stability and moving object clarity
2Reliability
If exposure time is extended to reduce atmospheric fluctuation impact, then image quality is improved, but motion blur increases
Solution Approach 1:
The patent implements feedback through the detection unit that continuously monitors fluctuation amount and feeds this information back to the determination unit. This closed-loop system adjusts exposure time based on real-time atmospheric conditions, extending exposure only when necessary to reduce atmospheric fluctuation while avoiding unnecessary motion blur during stable conditions
3Adaptability or versatility
If automatic control is implemented to adjust correction intensity, then adaptability to scenes is improved, but system complexity increases
Solution Approach 1:
The patent applies self-service by enabling the system to automatically detect fluctuation amount and determine appropriate exposure time without external intervention. The detection unit and determination unit work autonomously to adjust imaging parameters based on atmospheric conditions, providing scene adaptability while keeping the control logic contained within the imaging apparatus itself
