3D Video Display Parallax Adjustment for User Comfort
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video display apparatuses only adjust parallax levels based on screen size, not allowing users to customize their preferred parallax levels, leading to inconvenient viewing experiences for users who prefer lower parallax levels.
Innovation Solution
A video display apparatus and method that acquires video image size, sets a default parallax level adjustment value, allows users to change this value, and adjusts the parallax level accordingly, ensuring the parallax level aligns with user preferences and does not exceed the interpupillary distance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the parallax level is adjusted based on screen size to reproduce the producer's intended 3D image, then the 3D image reproduction accuracy is improved, but the user cannot customize their preferred parallax level
Solution Approach 1:
The system dynamically adjusts the parallax level based on screen size detection, automatically modifying the reproduction parameters to match the display environment. This resolves the contradiction by making the system adaptive rather than fixed, allowing it to maintain accuracy across different screen sizes while preserving user ability to override when desired
Solution Approach 2:
The system provides feedback to the user about the automatically adjusted parallax level and allows user input to override the automatic adjustment. This feedback mechanism resolves the contradiction by giving users awareness and control while maintaining the automatic accuracy-adjustment function
2Measurement precision
If the parallax level is increased for larger screen sizes to maintain intended reproduction, then the 3D image fidelity is improved, but the viewing comfort deteriorates when parallax exceeds interpupillary distance
Solution Approach 1:
The system changes the parallax parameter based on detected screen size, automatically adjusting it to maintain fidelity. When the screen size is large, the system can apply different parallax correction strategies to prevent exceeding interpupillary distance limits, thus maintaining both fidelity and comfort

AI summary
A video display apparatus can adjust the parallax level of stereoscopic video images in accordance with the video image size and allows a user to make further parallax adjustment. The video display apparatus acquires the video image size of the stereoscopic video images, sets a default value of a depth adjustment value for adjusting the parallax level of the stereoscopic video images based on the acquired video image size, changes the depth adjustment value when the user has provided an input representing a change in the depth adjustment value, sets a parallax adjustment level of the stereoscopic video images based on the changed depth adjustment value, and adjusts the parallax level of the stereoscopic video images based on the parallax adjustment level.
