3D Depth Adjustment via Disparity Scaling and Occlusion Filling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing 3D content systems fail to adjust the perceived depth of 3D movies and videos to accommodate individual viewer preferences, leading to discomfort such as eyestrain or mismatched depth perception due to fixed default settings.
Innovation Solution
A system comprising a content source, disparity estimator, processing circuitry, and warping engine that adjusts the perceived depth of 3D content by detecting disparities between stereoscopic images, applying a scale factor and offset based on viewer input, and synthesizing new stereoscopic images with altered depth using transformation models.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed default depth setting is used in 3D content, then the content can be produced and viewed consistently, but viewer comfort and adaptability deteriorate due to eyestrain and mismatched depth perception
Solution Approach 1:
The patent implements dynamic depth adjustment by allowing the disparity scale factor to be modified based on viewer preferences or viewing conditions. The processing circuitry dynamically scales the disparity values in the disparities array according to a scale factor that can be adjusted, transforming the fixed depth perception into an adaptable one that responds to user input or environmental changes.
Solution Approach 2:
The patent changes the parameter of disparity scale factor to adjust perceived depth. By modifying the scale factor applied to the disparities array, the system can transform the depth perception characteristics of the 3D content without changing the original content itself, enabling flexible adaptation to different viewer needs while maintaining consistent content structure.
2Reliability
If the baseline distance between stereoscopic cameras is kept fixed during production, then the 3D visual effects can be maintained consistently, but viewer comfort deteriorates when viewing distance does not match the intended depth
Solution Approach 1:
The patent introduces an intermediary processing stage between the fixed 3D content and the viewer's eyes. The processing circuitry acts as a mediator that adjusts the disparity values in the disparities array by applying a scale factor, effectively transforming the depth information to match the viewer's actual viewing distance and preferences, thereby eliminating eyestrain while preserving content consistency.
Solution Approach 2:
The patent changes the disparity parameter dynamically by applying adjustable scale factors to the disparities array. This allows the system to adapt the perceived depth to match the viewer's viewing distance and preferences, transforming the harmful fixed depth perception into a comfortable adjustable one without altering the original 3D content's consistency.
3Ease of operation
If 3D content is viewed at a fixed distance from the screen, then the viewing setup is simple, but viewer comfort and depth perception accuracy deteriorate when the fixed distance does not suit the viewer
Solution Approach 1:
The patent enables the 3D viewing system to serve itself by automatically adjusting depth parameters based on viewer input or viewing conditions. The processing circuitry can autonomously modify the disparity scale factor without requiring manual intervention or complex setup adjustments, maintaining ease of operation while improving depth perception accuracy through adaptive self-adjustment.
Solution Approach 2:
The patent dynamically changes the disparity parameter by applying adjustable scale factors to the disparities array, allowing the system to adapt depth perception to the viewer's actual viewing distance and preferences. This maintains the simplicity of the viewing setup while significantly improving depth perception accuracy through intelligent parameter adjustment.

AI summary
A system for adjusting the perceived depth of 3D content in response to a viewer input control signal. The system comprises: 1) a content source providing an input left stereoscopic image and an input right stereoscopic image; 2) a disparity estimator to receive the input left and right stereoscopic images, detect disparities between the input left and right stereoscopic images, and generate a disparities array; and 3) processing circuitry to fill in occlusion areas associated with the disparities array and apply a scale factor to the detected disparities to thereby generate a scaled disparities array. The system further comprises a warping engine to receive the scaled disparities array and generate an output left stereoscopic image and an output right stereoscopic image. The output left and right stereoscopic images have a different perceived depth than the input left and right stereoscopic images.
