Digital Telescope Distortion Correction for Globe Effect Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing digital telescopes and binoculars suffer from distortion issues known as the 'globe effect' due to human perception and varying viewing angles, which are not adequately addressed by current optical correction methods.
Innovation Solution
An image processor with adjustable distortion correction algorithms and sensors, allowing manual or automatic adjustment based on user input or motion detection, ensuring consistent and personalized distortion correction across multiple viewing scenarios.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If distortion correction is applied to eliminate the globe effect, then image accuracy is improved, but the correction cannot be adapted to individual user preferences and different viewing scenarios
Solution Approach 1:
The distortion correction algorithm is made dynamically adjustable through multiple correction levels (e.g., 0%, 50%, 100%) that can be selected based on viewing conditions and user preference. The system transitions from a static correction approach to a dynamic one where the correction intensity can be changed in real-time to adapt to different scenarios such as panning versus stationary observation.
Solution Approach 2:
The distortion correction parameter is made variable with different correction levels that can be applied. The system allows changing the distortion correction parameter from fully corrected to partially corrected or no correction at all, enabling adaptation to individual user preferences and different viewing scenarios without requiring multiple devices or complex configurations.
2Ease of operation
If automatic distortion correction is applied during panning, then the globe effect is reduced, but unnecessary correction may be applied during stationary observation
Solution Approach 1:
The system uses motion detection feedback to automatically adjust the distortion correction level. When motion is detected during panning, the system activates appropriate distortion correction to reduce the globe effect. When the telescope is stationary, the system reduces or disables correction to save processing energy, creating an adaptive system that responds to actual usage conditions.
3Manufacturing precision
If distortion correction is applied, then image geometric accuracy is improved, but the correction parameters are fixed and cannot be adjusted for different users or scenarios
Solution Approach 1:
The distortion correction system is made dynamically adjustable with multiple predefined correction levels and the ability to create custom profiles for different users. This allows the system to adapt to individual preferences and different viewing scenarios while maintaining geometric accuracy when needed, resolving the contradiction between fixed precision and flexible adaptability.
