Imaging Apparatus Setting Restoration for Exclusive Mode Confusion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of imaging apparatuses often become confused when setting information is restricted due to exclusive relationships between different imaging conditions, leading to unintended limitations in continuous shooting speed and potential loss of capturing high-speed images.
Innovation Solution
An imaging apparatus with a setting operation unit, storage unit, change unit, determination unit, and restoration unit that changes and restores setting information to prevent confusion by altering exclusive settings based on user operations and displaying specific screens to determine and correct unintended changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If setting information of a first setting item is changed, then the setting information of a second setting item selectable exclusively with respect to the setting information of the first setting item is automatically changed according to the setting information of the first setting item, but the user may perform a specific setting operation on the changed setting information of the second setting item intending to change it, while the automatic change causes confusion about whether the operation was intended
Solution Approach 1:
The system performs preliminary action by automatically changing the setting information of the second setting item when the first setting item is changed. This preliminary change is made before the user can perform any operation on the second setting item, which may cause confusion about user intention. The restoration function then provides a way to revert if the automatic change was not intended.
Solution Approach 2:
The system provides feedback by detecting when a specific setting operation is performed on the automatically changed second setting item and offering a restoration function. This feedback mechanism allows the user to correct unintended changes while maintaining the ability to make desired changes, thus resolving the confusion between automatic changes and user intentions.
2Reliability
If setting information is restricted due to exclusive relationships between different imaging conditions, then the imaging apparatus maintains proper setting combinations, but users become confused and may lose opportunities to capture images
Solution Approach 1:
The system provides self-service by automatically detecting when a user is confused about setting operations and offering restoration of previous settings. This eliminates the need for users to manually track which settings are valid combinations, reducing confusion and time loss while maintaining reliable setting combinations.
Solution Approach 2:
The system changes parameters by restoring setting information to previous values when confusion is detected. This parameter change capability allows users to quickly switch between different valid setting combinations without getting stuck in confused states, thus reducing time loss while maintaining setting validity.
3Reliability
If the continuous shooting speed is restricted to a low speed due to mechanical shutter selection, then the shutter system can handle the mechanical movement, but the user cannot perform high-speed continuous imaging as intended
Solution Approach 1:
The system applies dynamics by allowing the continuous shooting speed to change dynamically based on the selected shutter system. When a mechanical shutter is selected, the system automatically adjusts the maximum available continuous shooting speed to match the mechanical shutter's capabilities, ensuring reliable operation while informing users of the speed limitation.

AI summary
A digital camera includes a rear display unit, an imaging optical system, an operation button, a touch panel, a shutter unit, an imaging element, a main control unit, a digital signal processing unit, and a setting information storage unit. After setting information is set in a first setting item and a second setting item of an imaging condition, in a case where the setting information of the first setting item is changed through the touch panel, the main control unit changes the setting information of the second setting item to setting information according to the setting information of the first setting item after the change. When determination is made that a specific setting operation is performed, the main control unit reads the setting information of the first setting item and the second setting item from the setting information storage unit and restores the setting information to the setting information before the change.
