Multi-view Display Pixel Correlation for Light Field 3D Accuracy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing light field display technologies face challenges in accurately correlating multi-view image pixel information with display pixels, leading to inconsistencies in 3D image representation, especially when the number of view images does not match the number of viewing directions, resulting in potential distortion and an unnatural 3D experience.
Innovation Solution
An image processing method and apparatus that correlate pixel information from multi-view images with light field display pixels by determining the appropriate view image and interpolating pixel values based on the positions and directions of rays emitted from display pixels, using look-up tables and interpolation techniques to ensure accurate 3D representation across varying viewing conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If multi-view image pixel information is directly displayed without correlation processing, then the display process is simple, but the 3D image representation becomes inconsistent and distorted
Solution Approach 1:
The patent introduces an intermediary correlation processing unit that mediates between the multi-view image pixels and the light field display pixels. This unit performs view image determination and pixel value determination based on ray directions and display pixel positions, establishing a proper mapping relationship that resolves the inconsistency between simple display and accurate 3D representation
Solution Approach 2:
The patent performs preliminary correlation processing before the actual display. By determining which view image corresponds to which display pixel and calculating the appropriate pixel values in advance based on ray directions and viewing conditions, the system ensures accurate 3D representation is achieved without complicating the actual display process
2Adaptability or versatility
If the number of view images does not match the number of viewing directions, then the display can be flexible, but distortion and unnatural 3D experience occur
Solution Approach 1:
The patent changes the parameters of view image selection and pixel value interpolation based on the specific viewing conditions and ray directions. By dynamically adjusting which view image is used and how pixel values are interpolated, the system adapts to different numbers of view images and viewing directions while maintaining natural 3D representation
Solution Approach 2:
The patent implements a dynamic correlation processing system that adapts its behavior based on the number of view images and viewing directions. The view image determination and pixel value determination processes dynamically adjust to match the actual display configuration, ensuring consistency and naturalness regardless of the specific numbers involved
3Speed
If view image pixels are correlated with display pixels using fixed mapping, then the processing is fast, but the 3D representation becomes inaccurate under varying viewing conditions
Solution Approach 1:
The patent transitions from a fixed mapping approach to a dynamic correlation processing system. The view image determination and pixel value determination processes adapt to varying viewing conditions by considering ray directions and display pixel positions, achieving both speed and accuracy through efficient dynamic calculation
Solution Approach 2:
The patent applies different correlation processing to different display pixels based on their specific characteristics. Each display pixel is processed individually to determine the appropriate view image and pixel value based on its position and the corresponding ray direction, ensuring local accuracy while maintaining overall processing efficiency

AI summary
An image processing apparatus and method for processing an image using a multi-view image and pixel information are provided. The image processing method includes determining a view image that corresponds to a predetermined display direction of a display pixel of a display, determining at least one view image pixel corresponding to the display pixel in the determined view image based on a position of the display pixel in the display and pixel position information of the determined view image, and determining a pixel value of the display pixel based on a pixel value of the determined at least one view image pixel.
