Camera Body Error Handling for Interchangeable Lens Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing interchangeable lens type camera systems do not effectively inform users of communication errors or provide clear handling methods when issues occur, leading to cumbersome user experiences as they need to manually identify and resolve problems like prohibited release operations or power supply issues without clear guidance.
Innovation Solution
Incorporating an error detector and display unit in the camera body to detect communication errors and display specific error handling messages, such as prompts to remount the lens or power on again, guiding users through error resolution processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the camera body prohibits release operation or stops power supply when communication error occurs, then the system prevents abnormal operation, but the user cannot understand why the operation is prohibited and needs to manually check each unit
Solution Approach 1:
The patent implements a feedback mechanism by displaying specific error handling messages on the camera body's display unit, informing users of the communication error status and guiding them on appropriate handling methods. This feedback loop resolves the contradiction by maintaining system reliability through error detection while improving ease of operation through clear user guidance.
Solution Approach 2:
The error handling message serves as an intermediary between the camera body's internal error detection system and the user. Instead of requiring users to manually check each unit, the intermediary message clearly communicates the error status and suggested resolution, bridging the gap between system state and user understanding.
2Loss of information
If the system only notifies the user of warning or error status without providing handling methods, then the error notification is concise, but the user needs to check each unit manually to find the error and determine handling methods
Solution Approach 1:
The patent applies preliminary action by pre-providing error handling messages that include both error notification and suggested handling methods before the user needs to troubleshoot. This eliminates the need for users to manually check each unit, significantly reducing troubleshooting time while maintaining complete error information.
Solution Approach 2:
The error handling message provides comprehensive feedback to users, including both the error status and appropriate handling methods. This feedback mechanism eliminates information loss by ensuring users receive complete guidance on what to do, while reducing time loss by providing ready-to-follow resolution steps.
3Adaptability or versatility
If the camera body sends reset signal to interchangeable lens for initialization, then the lens may resume normal operation, but the user does not know why reset is performed and must manually check each unit
Solution Approach 1:
The patent implements feedback by displaying error handling messages that explain why a reset signal is sent to the interchangeable lens and guide users through the initialization process. This maintains the adaptability of the lens operation while improving ease of operation by providing clear user guidance on the reset procedure.
Solution Approach 2:
The error handling message acts as an intermediary between the camera body's reset function and the user. It explains the purpose of the reset operation and provides handling guidance, eliminating the need for users to manually check each unit while maintaining the flexibility of lens operation.
Data Source
AI summary
An interchangeable lens type camera system includes a camera body and an interchangeable lens mountable to the camera body. An error detector detects whether a communication error occurs between a communication unit of the camera body and a communication unit of the interchangeable lens. A display unit displays a first error handling message when the error detector detects the communication error at a time of activation of the interchangeable lens, and displays a second error handling message when the error detector detects the communication error after activation of the interchangeable lens.
