Eye Proximity Display Switching for Viewfinder Notification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display control systems for image capturing devices require users to change their posture to verify display setting switches, which can lead to confusion and loss of image capturing opportunities.
Innovation Solution
A display control apparatus with an eye proximity detection unit that switches display settings between an internal viewfinder and an external display, providing notifications to ensure users can verify setting changes without altering their posture, using a control unit to manage display states based on eye proximity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the display destination is switched from EVF to external display, then the external display shows the display target, but the user must change posture to verify the switch
Solution Approach 1:
The system provides visual feedback by displaying an icon on the EVF to indicate the current display destination. When the external display is selected, an icon appears on the EVF to inform the user of the switch without requiring them to change posture to verify the setting
Solution Approach 2:
The EVF serves as an intermediary information display device that provides status information about the display destination selection. Instead of requiring direct observation of the external display to verify settings, the EVF acts as a mediator that communicates the current state to the user
2Ease of operation
If the display destination is switched from external display to EVF, then the EVF shows the display target, but the user must view the EVF to check the switch status
Solution Approach 1:
The system provides immediate visual feedback on the EVF through icon display to indicate when the display destination has been switched. This allows users to confirm the switch status instantly without needing to redirect their gaze or adjust their posture
Solution Approach 2:
The system prepares and displays status information on the EVF in advance, so that when the user completes a display switching operation, the confirmation information is already available and does not require additional verification actions
3Loss of information
If a message is displayed on EVF to notify display setting switch, then the user can check the switch, but the notification is useless when the user is not viewing the EVF
Solution Approach 1:
Different notification methods are applied based on the user's viewing location. When the external display is the active display destination, status information is displayed on the external display itself rather than on the EVF, ensuring the notification is effective for the user's current viewing position
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables users to seamlessly switch and verify display settings without changing their posture, reducing confusion and loss of image capturing opportunities by using eye proximity detection to manage display notifications and states.
Implementation Method 1
an eye proximity detection unit configured to detect whether an eye is in proximity of the viewfinder as an eye proximity detection state

AI summary
A display control apparatus includes a first display internal to a viewfinder, a second display external to the viewfinder, an eye proximity detector, and an operation unit to switch a display on which a display target is displayed. The eye proximity detector detects, as a state, whether an eye is in proximity of the viewfinder. Where an obtained eye proximity detection state satisfies a first condition, a notification is displayed on a pre-switching display indicating that the display displaying the display target is to be switched. In response to a second condition being satisfied, the display of the display target is switched from the pre-switching display to a post-switching display. In a case where the obtained eye proximity detection state does not satisfy the first condition, the display target is switched to the post-switching display without displaying the notification on the pre-switching display.
