Stereoscopic Image Display Control via Face Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing 3D TV systems lack the ability to automatically convert stereoscopic images into planar images based on user face information and do not provide adequate methods for determining whether to allow stereoscopic image display, particularly for children under 5 years of age to prevent potential vision development issues.
Innovation Solution
An image display method and apparatus that acquires user face information, determines whether to allow stereoscopic image display based on interpupillary distance and face images, and converts stereoscopic images to planar images if necessary, with configuration options to restrict or limit stereoscopic image viewing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If stereoscopic image display is enabled for all users, then viewing enjoyment is improved, but vision development problems occur for children under 5
Solution Approach 1:
The system applies different image display qualities to different user groups: stereoscopic images for users above the age threshold and planar images for children under 5. This local differentiation resolves the contradiction by allowing stereoscopic viewing enjoyment for eligible users while protecting vulnerable children from vision development problems.
Solution Approach 2:
The system changes the display parameter from stereoscopic to planar based on the detected age parameter. When the user is determined to be under 5 years old, the system automatically converts the stereoscopic image to a planar image, thereby preventing vision development issues while maintaining access to content.
2Measurement precision
If automatic face recognition is implemented to determine stereoscopic image eligibility, then protection accuracy is improved, but device complexity increases
Solution Approach 1:
The system replaces manual age verification with automatic face recognition technology. The face recognition module detects facial features and determines age eligibility automatically, improving determination accuracy while the automated process actually reduces operational complexity compared to manual verification methods.
Solution Approach 2:
The face recognition system performs self-service by automatically detecting user age and making display mode decisions without requiring user input or manual configuration. The system serves itself by using the captured face image to determine whether to display stereoscopic or planar images.
3Object-affected harmful factors
If stereoscopic image conversion to planar image is performed, then vision protection is improved, but image dimensionality is reduced
Solution Approach 1:
The system performs preliminary anti-action by converting stereoscopic images to planar images in advance for children under 5, preventing potential vision development problems before they can occur. This proactive conversion protects vulnerable users while the system maintains the capability to display stereoscopic images for eligible users.
Solution Approach 2:
Instead of allowing stereoscopic viewing and converting only when problems are detected, the system inverts the approach by automatically converting to planar images for children and only displaying stereoscopic images for users confirmed to be above the age threshold. This inverted logic prioritizes protection while maintaining quality for eligible users.
