Camera Controller Shake Detection and Image Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies require high processing capability and user expertise to correct images affected by shake during photography, making it difficult to obtain shake-free images without complex hardware and high costs.
Innovation Solution
A controller with a photographing control unit and a shake detecting unit that continuously takes photographs and ends the process when the detected shake exceeds a predetermined level, allowing for efficient storage of the image with the least shake, thereby simplifying the process and reducing hardware requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If image correction process is used to remove shake disturbance, then shake-free images can be obtained, but processing complexity and hardware requirements increase
Solution Approach 1:
The system performs preliminary actions by continuously capturing multiple images before shake occurs, then selects the best image from the sequence. This preventive approach avoids the need for complex post-processing correction by ensuring the desired shake-free image is captured during the preliminary photographing sequence.
2Manufacturing precision
If complex image correction process is implemented, then shake disturbance can be removed, but hardware cost and processing capability requirements increase
Solution Approach 1:
The invention extracts only the necessary function from complex image correction systems by implementing a simple shake detection mechanism that triggers selective image capture. Instead of using complex hardware to correct images after capture, the system extracts and utilizes only the essential function of detecting shake and selecting appropriate images, thereby reducing hardware costs while maintaining image quality.
3Manufacturing precision
If user performs manual shake suppression, then shake-free images can be obtained, but user expertise and skill are required
Solution Approach 1:
The system performs self-service by automatically detecting shake through the shake detection unit and autonomously selecting images taken during low-shake periods. The photographing control unit automatically manages the sequence of image capture and selection without requiring user intervention or expertise in shake suppression techniques, making the process accessible to users of all skill levels.
4Manufacturing precision
If consecutive photographing is performed until shake increases, then shake-free images can be captured, but photographing time increases
Solution Approach 1:
The system implements feedback by continuously monitoring shake levels during the photographing sequence and using this real-time information to determine when to stop capturing images. The shake detection unit provides feedback about current shake conditions, allowing the photographing control unit to efficiently terminate the sequence once sufficient shake-free images have been captured, thereby minimizing photographing time while ensuring image quality.

AI summary
A controller is provided which includes a photographing control unit controlling an image pickup unit to take a photograph and a shake detecting unit detecting an amount of shake even time the image pickup unit takes a photograph. Here, the photographing control unit allows the image pickup unit to consecutively take a photograph and ends the photographing operation of the image pickup unit when the amount of shake detected by the shake detecting unit at the time of the photographing operation of the image pickup unit is larger than the amount of shake detected at the time of the previous photographing operation.
