Camera Body Shake Correction Coordination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The cooperation of blurring correction between interchangeable lenses and camera bodies is inconsistent, leading to mismatched blurring correction effects and unnatural live view images when the blurring correction settings of the camera body and interchangeable lens do not match.
Innovation Solution
A camera system with a camera body and accessory that includes movable units, detection units, calculation units, and transmission units to detect and correct blurring by sharing information about the moving distance of these units between the camera body and accessory, ensuring synchronized blurring correction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If blurring correction is implemented in both interchangeable lens and camera body, then blurring correction effect is improved, but setting consistency between lens and body deteriorates
Solution Approach 1:
The camera body transmission unit provides feedback to the interchangeable lens by transmitting body-side information (including moving distance calculation results) to the lens. This feedback mechanism enables the lens to adjust its blurring correction settings based on the camera body's movements, ensuring setting consistency while maintaining effective blurring correction in both components.
2Device complexity
If blurring correction settings are independent in lens and body, then device complexity is reduced, but image quality deteriorates due to unnatural live view images
Solution Approach 1:
The patent merges the blurring correction control systems by having the interchangeable lens and camera body operate as a coordinated unit. The lens receives body-side information from the camera body and adjusts its correction amount accordingly, creating a unified control system that maintains image quality while avoiding the complexity of fully independent settings management.
3Reliability
If camera body transmits body-side information to accessory, then blurring correction coordination is improved, but information transmission complexity increases
Solution Approach 1:
The patent extracts only the essential body-side information (including moving distance calculation results) needed for blurring correction coordination and transmits this specific data from the camera body to the interchangeable lens. This selective information extraction approach achieves effective coordination while minimizing information transmission complexity by focusing only on critical parameters.

AI summary
A camera body with which it is possible to improve the effect of shake correction, a camera accessory, and an information transmission method. The camera body of the present invention is a camera body to which a camera accessory can be detachably mounted, and is provided with: a movable section which is movable to correct shaking of the camera body; a detection unit which detects the shake and outputs a detection signal; a calculation unit which, on the basis of the detection signal, calculates an amount of movement of the movable section; and a transmission unit which transmits, to the camera accessory, body-side information the calculation unit uses to calculate the amount of movement.
