Inverted Reference Line for Camera Attitude Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
When using an external monitor to adjust the inclination of an imaging apparatus, the photographer faces difficulty in aligning the attitude correctly due to the apparent movement of the gravity reference line, which rotates in the opposite direction to the inclination of the imaging apparatus, making it challenging to adjust the imaging apparatus as intended.
Innovation Solution
A display control system that connects the imaging apparatus to an external display unit, where a detection unit detects the inclination and displays a reference line that rotates in accordance with this information, with the external display unit showing the reference line rotated in the opposite direction to align intuitively with the user, allowing easier adjustment of the imaging apparatus attitude.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the reference line is displayed fixedly on the external monitor, then the display is stable and easy to read, but the line does not rotate in accordance with the inclination of the imaging apparatus, making it difficult for the user to adjust the attitude correctly
Solution Approach 1:
The reference line displayed on the external monitor is made dynamic by rotating it in the opposite direction to the inclination of the imaging apparatus. This dynamic rotation provides real-time visual feedback about the apparatus's attitude, enabling the user to intuitively adjust the inclination while maintaining a stable and readable display.
2Ease of operation
If the gravity reference line rotates in the opposite direction to the inclination of the imaging apparatus, then the line appears stationary to a user viewing the back monitor, but the line appears to be moving on the external monitor, causing confusion
Solution Approach 1:
The patent applies inversion by rotating the reference line on the external monitor in the opposite direction compared to the back monitor display. While the back monitor shows a line that appears stationary (rotating with the apparatus), the external monitor shows a line that rotates oppositely to indicate inclination, providing reliable visual feedback for attitude adjustment.
3Ease of operation
If the reference line is displayed to rotate with the inclination on the external monitor, then the user can easily adjust the attitude, but the display becomes more complex compared to a fixed reference line
Solution Approach 1:
The system implements feedback by continuously monitoring the inclination of the imaging apparatus and automatically rotating the reference line on the external monitor in the opposite direction. This automated feedback mechanism provides intuitive visual guidance for attitude adjustment without requiring complex manual control or interpretation by the user.

AI summary
A display control apparatus having a connecting portion communicably connected to an imaging apparatus obtains an inclination angle of the imaging apparatus, and displays a displayed item on a display unit based on the obtained inclination angle. At this time, the display control apparatus performs control for displaying the displayed item indicating an inclination angle whose positive and negative have been inverted relative to positive and negative of the obtained inclination angle.
