Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional naked-3D technologies cause uncomfortable viewing experiences due to image jittering when viewers move, resulting from large pixel differences between image regions.
Innovation Solution
A method and apparatus that tune the smoothness of element images by selecting and filling pixel values into zones in ascending, descending, or duplicate orders, based on physical information of multi-optical elements, to reduce image differences and create a new integral image.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional naked-3D technology is used to display 3D images, then users can see 3D images with depth at specific viewing angles, but large pixel differences between image regions cause jittering or vibrating images when viewers move, resulting in uncomfortable viewing experiences
Solution Approach 1:
The patent applies parameter changes by modifying the pixel distribution parameters within element images. Specifically, it adjusts the pixel values and their spatial arrangement to reduce abrupt transitions between adjacent image regions. This is achieved by controlling the pixel differences through mathematical operations on the element images, thereby stabilizing the 3D image and eliminating jittering effects when viewers move.
Solution Approach 2:
The patent implements local quality by applying different pixel adjustment strategies to different regions of the element images. It identifies specific zones within element images that require pixel value modifications to reduce local pixel differences. By selectively adjusting pixel values in these local regions rather than uniformly across the entire image, the patent maintains overall image quality while reducing jittering in critical areas.
2Reliability
If pixel values are adjusted to reduce image differences between regions, then image jittering is reduced, but image features necessary for reproducing the 3D image must be preserved
Solution Approach 1:
The patent applies partial action by selectively adjusting pixel values only in specific regions and to specific degrees, rather than uniformly modifying the entire element image. It identifies critical regions where pixel differences cause jittering and applies adjustment operations primarily to these areas, using partial pixel value modifications that are sufficient to reduce jittering while preserving essential image features in other regions.
Solution Approach 2:
The patent carefully controls parameter changes by modifying pixel value parameters within specific ranges and applying transformation parameters that maintain the essential characteristics of the 3D image. The adjustment process uses controlled mathematical operations that change pixel distribution parameters while preserving the structural and semantic information necessary for accurate 3D image reproduction.

AI summary
The disclosure is related to a method for tuning a three-dimensional image, and a display apparatus thereof. In the method, an integral image composed of multiple element images and used to reproduce a three-dimensional image is obtained. The pixel values of every element image are extracted. Depending on hardware configuration, a certain range of the pixels within one-dimensional pixels of the element image are selected. The pixel values of the selected pixels are filled in the zones divided from the one-dimensional pixels in an ascending order or a descending order, and/or with continuously-duplicate values according to pixel numbers of the selected pixels. A new element image is therefore formed. By repeating these steps, a new integral image can be created. This new integral image effectively reduces the difference between the image regions and won't make a viewer see the uncomfortable three-dimensional image due to the excessively large difference.
