3D Picture Reproducing Apparatus Crosstalk Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Crosstalk occurs in 3D televisions, causing an unpleasant viewing experience due to overlapping images, particularly on LCD-type display panels where parallax images for the left and right eyes are not properly synchronized with the shutter glasses, leading to mixing and response time issues.
Innovation Solution
A picture reproducing method and apparatus that acquires information about the display panel type and retrieves suitable picture output conditions from a database to adjust the display, ensuring appropriate synchronization and luminance settings to prevent crosstalk, using a picture-dimensionality check unit, display panel check unit, and picture adjusting unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If parallax images are displayed on LCD-type display panels using conventional methods, then three-dimensional stereoscopic pictures can be provided, but crosstalk occurs causing images to overlap and giving an unpleasant feeling to the viewer
Solution Approach 1:
The system performs preliminary actions by acquiring display panel type information before displaying the 3D picture, retrieving appropriate picture output conditions from a database, and applying optimization settings in advance to prevent crosstalk rather than correcting it after occurrence
Solution Approach 2:
The system changes display parameters based on the detected panel type, retrieving specific picture output conditions (such as timing, luminance, and synchronization settings) from the database that are optimized for each panel type to eliminate crosstalk
2Object-affected harmful factors
If picture output conditions are optimized for each display panel type, then crosstalk can be reduced, but the system complexity increases due to database retrieval and panel type detection
Solution Approach 1:
The system performs self-service by automatically detecting the display panel type and retrieving appropriate optimization conditions without requiring manual user configuration, making the complexity management automatic rather than manual
Solution Approach 2:
The system uses feedback from the display panel check unit that provides information about the panel type to the picture adjusting unit, which then retrieves and applies appropriate picture output conditions, creating a closed-loop adaptive system

AI summary
A picture-dimensionality check unit checks whether or not a picture to be reproduced is a three-dimensional picture containing a first parallax image and a second parallax image, which are images of an object from different points of view in a three-dimensional space. A display panel check unit configured acquires, from a display apparatus by which the picture is displayed on a display panel, information including the type of the display panel on the condition that the picture to be reproduced is a three-dimensional picture. A picture adjusting unit retrieves from a database a picture output condition that provides suitable display of the picture on the display panel, on the basis of the information acquired by the display panel check unit, and to adjust the picture in accordance with the retrieved picture output condition.
