Camera Body Lens Shake Correction Synchronization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
When an interchangeable lens with a blurring correction apparatus is mounted on a camera body with a blurring correction apparatus, the cooperation between the two systems for blurring correction becomes inconsistent, leading to suboptimal image stabilization and unnatural live view images.
Innovation Solution
A camera system that includes a camera body and a detachable lens, each equipped with a movable unit, detection unit, and calculation unit, which communicate to synchronize blurring correction settings through command data and hotline communication, ensuring coordinated blurring correction between the camera body and lens.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If both camera body and interchangeable lens have blurring correction apparatuses, then blurring correction capability is enhanced, but coordination between the two systems becomes problematic
Solution Approach 1:
The camera body transmits body-side information (including blurring correction status and detection signals) to the interchangeable lens via communication unit 340b, enabling the lens to adjust its blurring correction based on real-time feedback from the camera body's blurring correction apparatus 265
Solution Approach 2:
The communication unit 340b serves multiple functions: transmitting not only blurring correction information but also other control data between the camera body and lens, consolidating multiple communication needs into a single interface
2Reliability
If blurring correction is performed independently by camera body and lens, then each system can correct blurring, but settings may mismatch leading to suboptimal results
Solution Approach 1:
The detection signal from the camera body's blurring correction apparatus 265 is transmitted to the interchangeable lens, allowing the lens to synchronize its correction settings with the camera body's real-time blurring correction status
Solution Approach 2:
The camera body transmits body-side information including blurring correction status before the interchangeable lens performs its blurring correction, ensuring the lens is pre-configured with appropriate settings

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 wherein the camera body to which a camera accessory can be detachably mounted, and includes: 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.
