Image Stabilization Apparatus for Panning Shot Blur Correction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image blur correction techniques during panning shots often fail to accurately stabilize images, especially when dealing with large objects, as the angular velocity varies across different portions of the object, leading to unintended blur correction.
Innovation Solution
An image stabilization apparatus comprising a detection unit to track object movement at multiple positions, a determination unit to define the object range, a holding unit to associate position information with movement data, and a control unit to correct image blur based on this information, ensuring accurate stabilization at the intended object position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional image blur correction technique is used during panning shots, then image stabilization is attempted, but accurate stabilization cannot be achieved when dealing with large objects due to varying angular velocities across different portions of the object
Solution Approach 1:
The patent divides the object detection into multiple segments by detecting object moving amounts at multiple positions on the screen using two consecutive images. This segmentation allows the system to capture different angular velocities at different portions of the object, enabling accurate blur correction for large objects where angular velocity varies across the object surface.
Solution Approach 2:
The patent applies local quality by determining object range based on detected moving amounts and holding object position information in association with moving amount information. This allows the image stabilization to be applied differently at different locations within the object range, accounting for the varying angular velocities at each position rather than using a uniform correction approach.
2Productivity
If angular velocity is calculated from object moving amounts, then blur correction is performed, but the calculated angular velocity varies depending on which portion of the object is used, leading to unintended correction positions
Solution Approach 1:
The patent segments the object detection process into multiple positions and determines object range based on the detected moving amounts. By segmenting the measurement process and using multiple reference points, the system achieves consistent angular velocity measurement across the entire object range, eliminating the variability that occurs when using single-point measurement.
Solution Approach 2:
The patent uses feedback by determining object range based on the results of detection and holding object position information in association with moving amount information. This feedback loop ensures that the angular velocity calculation is continuously refined based on the actual object position and moving amount detected, leading to consistent and accurate blur correction.
