Image Capturing Apparatus Mode Control via Lever Restriction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic apparatuses face inconsistencies when the setting to disable the operation member is changed while in operation mode, leading to unintentional changes in operation mode, causing user confusion and inefficiencies such as increased power consumption and resource wastage.
Innovation Solution
An electronic apparatus with a setting unit to restrict operation mode changes and a control unit that changes the operation mode from a first mode to a second mode when the restriction state is set, preventing unintended mode changes by enabling or disabling the operation member's instructions based on user input.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the setting is changed to disable the operation member while the electronic apparatus is operating in the predetermined operation mode, then the operation member's instruction is disabled to prevent erroneous operations, but an inconsistency arises between the setting being disable and the operation mode being the predetermined operation mode, which confuses the user
Solution Approach 1:
The control unit performs preliminary action by automatically changing the operation mode to a different operation mode when detecting that the setting has been changed to disable the operation member while in the predetermined operation mode. This preliminary action prevents the inconsistency from occurring and eliminates user confusion before it can arise.
2Ease of operation
If the operation member is configured to be operated by a one-touch operation to facilitate the change of the operation mode, then the ease of operation is improved, but the risk of unintentional change of operation mode due to erroneous operation increases
Solution Approach 1:
The system dynamically adjusts the operational state of the operation member based on the setting. When the setting is enabled, the operation member responds to one-touch operations for mode changes. When the setting is changed to disable, the control unit detects this change and automatically transitions to a different operation mode, preventing unintentional changes while maintaining ease of operation through automatic control.
3Reliability
If the instruction issued by operating the operation member is continually disabled when the setting is made to disable, then erroneous operations are prevented, but resource wastage occurs when the apparatus continues to operate in the predetermined operation mode unnecessarily
Solution Approach 1:
The control unit performs preliminary action by automatically changing the operation mode when detecting that the setting has been changed to disable the operation member while in the predetermined operation mode. This prevents the inconsistency and ensures that the apparatus operates in an appropriate mode, avoiding unnecessary resource consumption while maintaining reliability.

AI summary
The present disclosure is directed to preventing an operation from being performed in an operation mode that is not intended by a user. In an image capturing apparatus, a moving image lever is an operation member for issuing an instruction to change an operation mode to a moving image capturing mode that is a state where a moving image is recordable. In order to avoid unintentional change of the operation mode to the moving image capturing mode due to an erroneous operation on the moving image lever, a setting is made to enable and disable an instruction that is issued by operating the moving image lever. If the setting is changed to “disable” while the image capturing apparatus is operating in the moving image capturing mode, a microcomputer changes an operation mode to a still image capturing mode.
