Intermediate Accessory Apparatus for Camera Control Information
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing imaging systems face challenges in efficiently acquiring and combining control information specific to interchangeable lens apparatuses and intermediate accessory apparatuses, which is resource-intensive and requires complex hardware and software combinations.
Innovation Solution
The implementation of a dual communication path system within the imaging system, where a first communication method is used between the camera body and the interchangeable lens apparatus, and a second communication method is used between the camera body and the intermediate accessory apparatus, allows for efficient acquisition and combination of control information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the camera body directly combines control information from both the interchangeable lens apparatus and intermediate accessory apparatus, then control accuracy is improved, but device complexity and resource consumption increase
Solution Approach 1:
The intermediate accessory apparatus acts as a mediator that receives control information from both the interchangeable lens apparatus and the camera body, combines this information, and outputs the integrated control signals to the lens apparatus. This eliminates the need for the camera body to directly perform complex combination operations, thereby reducing device complexity while maintaining control accuracy.
2Reliability
If the camera body acquires and combines all control information, then control completeness is improved, but preparation time increases
Solution Approach 1:
The intermediate accessory apparatus performs preliminary actions by pre-acquiring and pre-combining control information from the interchangeable lens apparatus and itself before the camera body needs to execute imaging operations. This advance preparation reduces the time required for the camera body to acquire and process control information, while ensuring complete control data is available when needed.
3Productivity
If a single communication path is used between camera body and lens apparatus, then system simplicity is maintained, but information transmission efficiency decreases
Solution Approach 1:
The communication system is segmented into multiple independent communication paths: one between the camera body and the intermediate accessory apparatus, and another between the camera body and the interchangeable lens apparatus. This segmentation allows parallel information transmission, improving efficiency by enabling simultaneous data exchange without interfering with each other, while each individual communication path remains relatively simple.
