Dual Display Imaging Apparatus Proximity Triggered Live View
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional digital cameras face difficulties in allowing both the photographer and the shooting subject to simultaneously check desired information during image shooting, especially when using a finder and a movable monitor, as the live view display cannot be performed simultaneously in such scenarios.
Innovation Solution
The digital camera transitions to a 'both display state' where the finder and movable monitor perform live view display simultaneously, triggered by the reversal of the movable monitor and detection of proximity to the finder, enabling the display of the subject's image on both screens without showing shooting information on the movable monitor when an object is detected, and displaying shooting information only on the finder.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the live view display is performed simultaneously on both finder and movable monitor, then both photographer and subject can check desired information, but power consumption increases
Solution Approach 1:
The patent implements dynamic control of display states based on real-time detection conditions. The controller switches between different display configurations (first display state, second display state, third display state) depending on whether the monitor is reversed and whether an object is detected by the proximity detector, optimizing power consumption while maintaining usability
Solution Approach 2:
The system uses periodic detection cycles to monitor the reversal state of the movable monitor and the proximity of objects. The proximity detector continuously detects objects at predetermined intervals, and the controller periodically adjusts display states based on these detections, enabling efficient power management through intermittent rather than continuous full-display operation
2Ease of operation
If the movable monitor is reversed to face the subject, then the subject can see the display, but the photographer cannot check shooting information on the monitor
Solution Approach 1:
The patent segments the information display function between two separate displays: the finder displays shooting information to the photographer, while the movable monitor displays the live view to the subject. This segmentation allows both users to access their required information simultaneously without interfering with each other
Solution Approach 2:
The finder acts as an intermediary device that provides shooting information to the photographer when the movable monitor is reversed. Instead of requiring the photographer to view the monitor directly, the finder mediates by presenting the same or complementary information through the optical viewfinder
3Loss of information
If shooting information is displayed on both finder and movable monitor, then both users have complete information, but the display becomes cluttered and less usable
Solution Approach 1:
The patent applies local quality by displaying different types of information on different displays according to their intended audiences. The finder displays shooting information (exposure settings, focus status) suitable for the photographer, while the movable monitor displays the live view image suitable for the subject, with each display optimized for its specific purpose

AI summary
An imaging apparatus for capturing an image of a subject, the imaging apparatus includes: a first display; a second display including a display screen configured to change an orientation toward a subject side; a controller configured to control operations of the first and second displays; and a proximity detector configured to detect an object in proximity to the first display, wherein when a predetermined condition is satisfied, the controller causes the first display to display an image of the subject, and causes the second display to display an image showing the subject simultaneously with the first display.
