Imaging Support Control for Stable Subject Tracking Under Shake
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing imaging systems face challenges in accurately tracking and adjusting the position of a target subject within a captured image, particularly in dealing with image shake caused by vibrations and subject movement, while efficiently utilizing available mechanisms like revolution and shake correction.
Innovation Solution
An imaging support device that calculates and adjusts the position of a target subject image by deriving a movement amount based on in-image shift, focal length, and pixel interval, using a combination of revolution and shake correction mechanisms to maintain image stability and tracking accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If shake correction mechanisms are used to correct image shake caused by vibrations, then image stability is improved, but device complexity increases due to additional correction components
Solution Approach 1:
The patent combines the shake correction mechanism with the revolution mechanism into an integrated system. The shake correction unit and revolution unit share common components and control structures, allowing the system to correct image shake while maintaining relatively simple device architecture. This merging approach resolves the contradiction by achieving image stability without proportionally increasing device complexity.
2Measurement precision
If revolution mechanisms are used to adjust the position of the target subject image, then tracking accuracy is improved, but device complexity increases due to additional mechanical components
Solution Approach 1:
The revolution mechanism is designed to serve multiple functions: it adjusts the position of the target subject image for tracking purposes, and it also works in conjunction with the shake correction mechanism to maintain image stability. By making the revolution mechanism multi-functional, the patent achieves improved tracking accuracy without requiring separate dedicated components for each function, thus limiting the increase in device complexity.
3Reliability
If both shake correction and revolution mechanisms are combined to maintain image stability and tracking accuracy, then imaging performance is improved, but device complexity and difficulty of operation increase
Solution Approach 1:
The control unit automatically manages the coordination between the shake correction mechanism and the revolution mechanism without requiring manual intervention. The system self-adjusts by processing captured images, detecting target subject positions, and automatically controlling both mechanisms to work together. This automation improves imaging performance while maintaining ease of operation, as the system handles the complexity internally without burdening the user.

AI summary
An imaging support device that supports imaging performed by an imaging apparatus includes an acquisition portion that acquires an in-image shift amount between a predetermined position in a captured image obtained by capturing an imaging region by an imaging element and a position of a target subject image showing a target subject, and a focal length of the imaging apparatus, a derivation portion that derives a movement amount required for moving the position of the target subject image to a specific position by a position adjustment portion which adjusts the position of the target subject image in the captured image, based on the in-image shift amount acquired by the acquisition portion, the focal length acquired by the acquisition portion, and information related to a pixel interval of pixels in the imaging element, and an output portion that outputs the movement amount derived by the derivation portion.
