Virtual Mirror Image Offset for Front Camera Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Virtual mirrors on terminal devices have a poor image display effect compared to physical mirrors, leading to a suboptimal user experience due to deviations in image composition and increased observation angles.
Innovation Solution
The method involves obtaining an offset corresponding to a specific display specification, which is used to crop and display a target image on the terminal device's display. This offset ensures that the center of the target image is positioned similarly to a physical mirror's image, improving the image display effect.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the front-facing camera is used to shoot the user image for virtual mirror display, then the terminal device can provide virtual mirror function without physical mirror, but the image display effect is poor due to center offset and increased observation angles
Solution Approach 1:
The patent applies asymmetry by intentionally offsetting the target image center from the display center towards the front-facing camera position. This asymmetric adjustment compensates for the camera-display spatial relationship, making the virtual mirror image more consistent with physical mirror reflection geometry and improving image display quality.
Solution Approach 2:
The patent changes the spatial parameters of the displayed image by adjusting the offset between the target image center and display center based on the front-facing camera position. This parameter adjustment optimizes the observation angle and image composition, resolving the poor image display effect while maintaining virtual mirror functionality.
2Device complexity
If the target image center is positioned at the display center, then the display layout is simple, but the image composition deviates from physical mirror reflection and increases observation angles
Solution Approach 1:
The patent introduces asymmetric positioning of the target image center relative to the display center, shifting it towards the front-facing camera position. This asymmetric layout optimizes the observation angle to match physical mirror usage patterns, improving ease of operation while maintaining reasonable display complexity.
3Manufacturing precision
If the offset between target image center and original image center is increased, then the image composition becomes more similar to physical mirror, but the cropping region changes and may affect image content
Solution Approach 1:
The patent optimizes the offset parameter between the target image center and original image center based on the front-facing camera position and display characteristics. This parameter optimization achieves accurate image composition similar to physical mirrors while minimizing image content loss through appropriate cropping region selection.
