Solution Overview
Problem
Existing camera systems face challenges in accurately transmitting information about the state of interchangeable lenses, which can compromise vibration correction performance if the transmitted information is inappropriate.
Innovation Solution
A camera accessory system that includes a correction optical system movable in a direction intersecting the optical axis and a communication unit for transmitting information about the position of the correction optical system and vibration data to the camera body, enabling effective vibration correction by synchronizing the vibration states between the camera body and the interchangeable lens.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If information about the state of an interchangeable lens is transmitted to a camera body, then the camera system can perform vibration correction, but the vibration correction performance will be compromised if the transmitted information is inappropriate
Solution Approach 1:
The patent implements a feedback mechanism where the camera body transmits vibration information to the interchangeable lens, and the lens responds by adjusting its correction optical system. The system continuously monitors the vibration state and adjusts the correction amount accordingly, ensuring that the transmitted information is always appropriate for the current vibration conditions. This feedback loop prevents information transmission errors from degrading vibration correction performance.
Solution Approach 2:
The patent employs dynamic adjustment of the correction optical system based on real-time vibration information. The correction amount is not fixed but varies dynamically according to the vibration state detected by the camera body's vibration detection unit. This dynamic approach ensures that the information transmitted between camera and lens always reflects the current operational state, maintaining optimal vibration correction performance.
2Reliability
If a correction optical system is made movable to correct vibration, then vibration correction capability is improved, but the device complexity increases
Solution Approach 1:
The patent divides the vibration correction function into two separate components: a correction optical system in the interchangeable lens and a vibration detection system in the camera body. This segmentation allows each component to be optimized independently - the lens focuses on optical correction while the camera handles vibration sensing and control information transmission. This division reduces the overall complexity compared to having a fully integrated system in one location.
Solution Approach 2:
The patent introduces an intermediary communication system that transmits vibration information between the camera body and the interchangeable lens. This intermediary layer allows the two components to work together without requiring direct mechanical or electrical integration, thereby reducing device complexity. The communication interface serves as a mediator that coordinates the actions of the correction optical system based on vibration detection data.
