Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current three-dimensional integral imaging methods face challenges in achieving high resolution while maintaining depth-based direct imaging, as they either prioritize depth over resolution or vice versa, resulting in suboptimal performance in both aspects.
Innovation Solution
A method utilizing a mask and time division multiplexing, where element images from a three-dimensional object are passed through a lenslet and a mask with alternating blocking and transmission regions, enhancing resolution by displaying element images in a time division manner, allowing for a wider depth feeling and more realistic three-dimensional images.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If depth-based direct imaging method is used, then depth feeling is improved, but resolution deteriorates
Solution Approach 1:
The patent applies time division multiplexing to display different element images corresponding to different depth regions in alternating time periods. The display device sequentially shows element images for near depth regions and far depth regions, with each set of element images being displayed in a periodic manner. This periodic action enables the system to maintain depth-based direct imaging while achieving four-times resolution enhancement through multiple display cycles.
Solution Approach 2:
The patent segments the depth space into multiple depth regions (near depth region and far depth region) and assigns different element images to each region. By dividing the depth space and processing element images for each segment separately, the system can optimize resolution for each depth region while maintaining overall depth perception, thereby resolving the contradiction between depth feeling and resolution.
2Device complexity
If conventional integral imaging method is used, then device complexity is reduced, but image resolution deteriorates
Solution Approach 1:
The patent introduces dynamic time division multiplexing control to the integral imaging system. The display device dynamically switches between displaying different element images corresponding to different depth regions and spatial locations. This dynamic control enables resolution enhancement without requiring complex additional hardware, as the same display device is used sequentially for different imaging tasks.

AI summary
A method for displaying three-dimensional integral images using a mask and a time division multiplexing which is configured in such a way that a three-dimensional image is displaced in a space as an element image obtained from a three-dimensional object is passed through a lenslet and a mask, the mask consisting of a blocking region through which an element image does not pass and a transmission region through which an element image passes, for thereby displaying three-dimensional images. The present invention is advantageous to play back a three-dimensional image the resolutions of which are enhanced in a depth-based integral imaging method using a time division display of an element image and a masked image.
