Multi-View Image Grayscale Mapping to Reduce 3D Display Ghosting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing naked-eye 3D display technologies face challenges in reducing crosstalk rates, which lead to noticeable ghosting, making it difficult to improve the display effect.
Innovation Solution
An apparatus and method that adjusts pixel grayscale values in multi-view images based on a predetermined mapping relationship derived from ghosting sensitivity measurements, identifying target regions with significant brightness differences and applying threshold values to reduce crosstalk.

Engineering Contradiction Analysis
1Object-affected harmful factors
If the crosstalk rate is reduced by improving display apparatus design parameters, then ghosting is reduced, but the display apparatus design becomes more complex
Solution Approach 1:
The patent introduces an image processing apparatus as an intermediary between the multi-view image generator and the display apparatus. This processing apparatus applies a predetermined mapping relationship to adjust pixel grayscale values, thereby reducing crosstalk-induced ghosting without requiring changes to the display apparatus design itself. The mapping relationship acts as a mediator that compensates for the harmful crosstalk effect through software-based correction rather than hardware modification.
2Object-affected harmful factors
If pixel grayscale values are adjusted in target regions, then brightness differences and ghosting are reduced, but image processing complexity increases
Solution Approach 1:
The patent applies local quality adjustment by selectively modifying pixel grayscale values only in target regions where brightness differences exceed a predetermined threshold. The processing apparatus identifies these specific regions through comparison of adjacent viewpoint images and applies the mapping relationship only where necessary, rather than uniformly adjusting all pixels. This localized approach reduces processing complexity compared to global adjustment while effectively addressing ghosting in problematic areas.
Solution Approach 2:
The patent changes the parameter of pixel grayscale values by applying a predetermined mapping relationship that transforms the original grayscale values in target regions. This parameter transformation adjusts the brightness characteristics of specific pixels to reduce crosstalk effects. The mapping relationship provides a systematic way to modify parameters without requiring complex real-time calculations, thereby managing processing complexity while achieving the desired brightness differentiation.
