Imaging Apparatus Rotating Center Position Shake Correction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing imaging apparatuses are limited in their ability to effectively correct for camera shake in the rotating direction, as they rely on preset assumptions that fail to account for various types of camera shake, particularly in the roll direction.
Innovation Solution
An imaging apparatus that includes an optical system, an imaging device, a detecting unit for rotational shake, a cutting-out unit that determines a rotating center position based on conditions like focal length or motion amount, and a recording unit to rotate and cut out image data, thereby reducing the effect of rotational shake.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a fixed preset rotating center position is used for camera shake correction, then the correction process is simple and fast, but the correction effectiveness is limited and cannot adapt to various rotating camera shake types
Solution Approach 1:
The patent applies dynamics by making the rotating center position variable rather than fixed. The cutting-out unit dynamically determines the rotating center position based on detected camera shake characteristics (such as shake direction and magnitude), allowing the system to adapt to different rotating camera shake types while maintaining efficient processing through automated detection and calculation.
2Device complexity
If a fixed preset rotating center position is used, then the device complexity is low, but the manufacturing precision of camera shake correction is insufficient
Solution Approach 1:
The patent implements feedback by having the detecting unit continuously monitor camera shake characteristics and feed this information back to the cutting-out unit. Based on this feedback, the cutting-out unit adjusts the rotating center position to optimize correction precision, creating a closed-loop system that improves manufacturing precision without significantly increasing device complexity through automated control.
3Manufacturing precision
If the rotating center position is determined based on focal length or motion amount, then the correction precision is improved, but the calculation complexity increases
Solution Approach 1:
The patent applies parameter changes by determining the rotating center position based on variable parameters such as focal length and motion amount detected by the detecting unit. The cutting-out unit adjusts the rotating center position according to these parameter values, enabling precise correction adapted to specific shooting conditions while managing calculation complexity through systematic parameter-based approaches.

AI summary
An imaging apparatus includes an optical system, an imaging device that captures an image imaged via the optical system to generate image data, a detecting unit that detects a shake of the imaging apparatus in a rotating direction, a cutting-out unit that cuts out data in a predetermined cutting-out region in a region of the image data generated by the imaging device, and a recording unit that records the cut image data in a recording medium. The cutting-out unit determines a rotating center position according to a predetermined condition (for example, the focal length of the optical system or move amount of the imaging apparatus), rotates the cutting-out region around the rotating center position to reduce an effect of the shake in the rotating direction detected by the detecting unit on the image imaged on the imaging device, and cuts out the image data from the rotated cutting-out region.
