Image Blur Correction for Smooth Object Part Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image blur correction techniques fail to maintain image quality when switching object parts for detection, leading to unnatural changes in object positions within the image.
Innovation Solution
An image blur correction apparatus that calculates and adjusts the object blur correction amount based on the difference between the selected object part and a predetermined target position, and optionally adjusts the target position, to stabilize the object's position in the image even when part switching occurs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the object detection unit switches between different parts of an object for detection, then the selection unit can maintain tracking of the object, but the object blur correction amount calculation unit produces unnatural position changes in the image
Solution Approach 1:
The patent introduces an intermediary calculation process that computes the position difference between the first detected part and the second detected part, then uses this difference to adjust the target position. This intermediary step acts as a mediator that bridges the transition between different object parts, preventing abrupt position changes while maintaining continuous tracking.
Solution Approach 2:
The patent applies preliminary anti-action by calculating the position difference between object parts in advance, before the actual switching occurs. This pre-calculated difference is then used to offset the target position, preventing the unnatural position jump from occurring in the first place.
2Stability of the object's composition
If the system maintains a fixed target position for object blur correction, then the object position remains stable in the image, but switching object parts causes unnatural position changes
Solution Approach 1:
The patent makes the target position dynamic by allowing it to change based on the detected object part. Instead of a fixed target position, the system dynamically adjusts the target position according to the position difference between different object parts, enabling both stability and adaptability.
Solution Approach 2:
The patent changes the parameter of target position based on the detected object part. When switching from one object part to another, the target position parameter is adjusted by the calculated position difference, allowing the system to adapt to different object parts while maintaining smooth transitions.
3Device complexity
If the object blur correction amount is calculated based solely on the difference between the selected object part and the fixed target position, then the calculation is simple, but the position changes unnaturally when switching parts
Solution Approach 1:
The patent performs preliminary action by calculating the position difference between the first object part and the second object part before the actual part switching occurs. This pre-calculated difference is then incorporated into the target position adjustment, ensuring that the correction amount calculation remains relatively simple while avoiding unnatural position changes.

AI summary
An image blur correction apparatus comprises an object detection unit configured to output a position of the part of the object, a selection unit configured to select a part of an object from among parts of one or more objects, and an object blur correction amount calculation unit configured to calculate an object blur correction amount, wherein the object blur correction amount calculation unit, when a part of an object selected by the selection unit is switched from a first part to a second part, calculates the object blur correction amount based on a difference between a position of the selected part of the object and the target position, a position of the second part in an image, and a position of the first part in an image acquired before switching.
