Dynamic Face Area Display Positioning to Reduce Optical Distortion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display methods for electronic devices often result in distortion when simultaneously displaying a user's face and a local area of their face, particularly due to the local area being far from the main optical axis of the photographing unit.
Innovation Solution
A display method that determines a target position for displaying image data of a local area of the user's face, ensuring it is close to the main optical axis of the photographing unit when the user looks at it, thereby reducing distortion by reversing the display relationship, such as positioning the local area diagonally relative to the user's face.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the local area of the user's face is displayed independently at a fixed position on the display area, then the user can view the local area clearly, but distortion occurs when the local area is far from the main optical axis of the photographing unit
Solution Approach 1:
Instead of fixing the display position and accepting distortion, the patent inverts the approach by dynamically determining the display position based on the photographing unit's optical axis. The local area's display position is adjusted so that it remains close to the main optical axis, thereby eliminating distortion while maintaining clear visibility
Solution Approach 2:
The display position of the local area is made dynamic rather than fixed. The system continuously adjusts the display position according to the photographing unit's orientation and the user's face position, ensuring the local area remains optimally positioned relative to the optical axis to minimize distortion
2Device complexity
If the display position of the local area is fixed, then the display system is simple, but the local area may be far from the main optical axis causing distortion
Solution Approach 1:
The system transitions from a static fixed-position display to a dynamic position-determination system. The display position is automatically calculated based on the photographing unit's optical axis and the local area's position on the user's face, adding computational complexity but eliminating image distortion
Solution Approach 2:
The patent replaces potential mechanical adjustment mechanisms with a computational approach. Instead of physically moving components to adjust the display position, the system uses coordinate transformations and calculations to determine the optimal display position, reducing mechanical complexity while achieving the same goal

AI summary
The present disclosure provides a display method. The display method includes obtaining a selection operation of a user's face; obtaining image data of a local area of the user's face corresponding to the selection operation; determining a target position at a display area for displaying the image data of the local area; and displaying the image data of the local area at the target position. When the user looks at the target position relative to other positions at the display area, the local area of the user's face is close to a main optical axis of a photographing unit.
