Rotatable Display Image Orientation Control for Self-Image Capture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image capturing apparatuses face usability and composition freedom issues due to fixed display orientation settings based solely on the display unit's position, which can lead to inappropriate field angles for self-image capturing, causing misinterpretation of capture intentions and suboptimal settings.
Innovation Solution
An image capturing apparatus with a rotatable display unit that detects rotation and field angle information, dynamically adjusting the display direction to enhance usability and composition freedom by switching between normal and self-image capturing modes based on specific angle thresholds and lens field angles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If control is performed to constantly prioritize self-image capturing based on display unit orientation, then self-image capturing usability is improved, but normal image capturing freedom is degraded
Solution Approach 1:
The patent changes the control parameter from binary (self-image or normal) to continuous (rotation angle degree), enabling dynamic adjustment of display inversion based on the specific rotation angle. This resolves the contradiction by allowing the system to adapt to different capture scenarios within a spectrum of rotation angles, rather than forcing a binary choice that degrades either self-image usability or normal capture freedom.
Solution Approach 2:
The patent introduces dynamic control where the display inversion state changes continuously based on the rotation angle of the display unit. Instead of a fixed control mode, the system dynamically adjusts between inverted and non-inverted display based on the detected rotation angle, enabling both self-image and normal capturing modes to function appropriately across different rotation positions.
2Area of stationary object
If widest angle is used for self-image capturing, then field of view is improved, but distortion aberration increases
Solution Approach 1:
The patent enables dynamic selection of appropriate field angles based on rotation angle and capture type. The system can switch between widest angle for self-image capturing and other field angles for normal capturing, allowing optimization of both field of view and distortion characteristics for different capture scenarios.
Solution Approach 2:
The patent applies different optical characteristics (field angles) to different capture scenarios. Instead of using a fixed widest angle for all situations, the system selects appropriate field angles locally optimized for either self-image capturing (prioritizing field of view) or normal capturing (prioritizing image quality with reduced distortion).

AI summary
An image capturing apparatus includes an image capturing unit to capture an image of a subject via an optical system, and a display unit having a display surface configured to display the image, and being rotatably supported with respect to the image capturing unit. In an exemplary embodiment, an open and close angle of a display panel and a rotation angle threshold to be used when the display unit is changed to “a self-image capturing display” according to an image capturing field angle are changed, thereby switching an orientation of the image in the display in consideration of not only an orientation of the display panel but also an image capturing field angle.
