3DTV Image Adjustment Controller for Depth Perception and Brightness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Viewing 2D-to-3D generated videos can be dim due to light blockage by 3DTV glasses, and different viewers have varying sensitivities to depth perception, which can cause eye strain and discomfort, especially during transitions in high-action sequences or commercial breaks.
Innovation Solution
A method and apparatus that allow users to adjust default image settings such as brightness, depth, contrast, and focus for personalized 3DTV experiences, using a 2D-to-3D image adjustment controller to customize settings based on individual preferences, which can be stored and recalled for each user, and applied during 2D-to-3D video conversion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If 3DTV glasses are used to view 2D-to-3D generated video, then depth perception is provided, but the video appears dim due to light blockage
Solution Approach 1:
The patent adjusts brightness parameters of the 3D image to compensate for light blockage caused by glasses. The system modifies luminance levels and brightness distribution in different regions of the image to maintain perceived brightness despite the filtering effect of 3D glasses
2Reliability
If default 3D image settings are used, then standard depth perception is provided, but viewers with different sensitivities experience eye strain and discomfort
Solution Approach 1:
The patent applies different depth and brightness parameters to different regions of the 3D image. Objects at different depths receive customized adjustment parameters, allowing regions that cause eye strain to be specifically modified while preserving depth perception in other areas
Solution Approach 2:
The system dynamically adjusts depth and brightness parameters based on scene content and motion detection. During high-action sequences or commercial breaks with multiple scene changes, the system modifies parameters in real-time to prevent eye strain while maintaining depth perception
3Speed
If high motion content or multiple scene changes occur in 2D-to-3D video, then action sequences are enhanced, but depth perception sensitivity issues become more pronounced
Solution Approach 1:
The system continuously analyzes scene content and motion characteristics, then adjusts depth and brightness parameters in response to detected changes. This feedback mechanism ensures that depth perception remains stable during high-motion sequences by dynamically adapting parameters to current scene conditions

AI summary
A method (300) and apparatus (400) for three-dimensional television (3DTV) image adjustment includes loading (342, 344) default 2D-to-3D image setting values from a default settings memory to a user adjustment settings memory, annunciating (346) the default 2D-to-3D image setting values, receiving (361, 362) a 2D-to-3D image settings value adjustment, saving (370) the 2D-to-3D image settings value adjustment in the user adjustment settings memory, and applying (390) the 2D-to-3D image settings value adjustment to a 2D-to-3D converted image. These methods and apparatuses allow individual users to set 3DTV image settings to their personal preferences to compensate for brightness reductions caused by 3DTV glasses, depth perception sensitivities, and other image quality factors.
