Stereo Content Depth Customization via Disparity Shifting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current 3D television systems lack the ability to adapt and customize the depth of 3D content to individual viewer preferences, leading to discomfort due to fixed depth ranges that do not accommodate varying comfort levels of viewers.
Innovation Solution
A method and system that adjust the horizontal disparity of stereoscopic image pairs in response to viewer control signals, allowing for customization of depth perception by shifting and scaling the left and right images to align with the viewer's comfort and preference, thereby changing the perceived depth of objects in a scene.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the depth range is increased to create lifelike 3D effects in home theater, then the visual impact is improved, but viewer comfort deteriorates
Solution Approach 1:
The system dynamically adjusts the depth range of 3D content based on viewer feedback and preferences. The processing device modifies disparity values in real-time, allowing the depth characteristics to change adaptively rather than remaining fixed, thereby resolving the contradiction between visual impact and viewer comfort
Solution Approach 2:
The invention changes the disparity parameter of stereoscopic image pairs to adjust depth perception. By modifying horizontal pixel displacement between left and right views, the system can reduce depth range to improve comfort while maintaining visual engagement, directly addressing the contradiction
2Device complexity
If the depth range is fixed for all viewers, then system complexity is reduced, but adaptability to individual preferences deteriorates
Solution Approach 1:
The system enables viewers to self-adjust depth preferences through feedback mechanisms. Users can provide input about their comfort levels, and the processing device automatically adjusts disparity parameters accordingly, eliminating the need for complex manual configuration while achieving personalization
Solution Approach 2:
The invention incorporates feedback loops where viewer responses to depth perception are captured and used to adjust subsequent rendering. This feedback mechanism allows the system to adapt to individual preferences without requiring complex pre-programming, balancing simplicity with adaptability

AI summary
A method and system for adjustable 3-dimensional content are described in which a viewer can adjust the depth range according to the viewer's own visual comfort level and/or viewing preference. The depth change is achieved by shifting the left and right images of stereoscopic content image pairs so that corresponding pixels in the shifted left and right images of a stereoscopic pair exhibit a new horizontal disparity sufficient to achieve the desired depth change. By shifting the left and right images in an image pair, content objects in the scene can appear closer to, or farther away from the viewer than those same objects in the un-shifted image pair. This technique achieves a viewer controlled customization of the sensation of depth in the stereoscopic 3-dimensional content.
