Solution Overview

Problem

Current 3D displays face challenges in enlarging images without deteriorating resolution, particularly in multiview scenarios where the number of views and resolution per view create a trade-off, leading to reduced image quality.

Innovation Solution

An image enlarging apparatus and method that designates specific regions for enlargement, determines an appropriate enlargement rate, and uses scalable multiplexing to resize and adjust disparity, allowing for partial image enlargement without reducing resolution by maintaining or exceeding the resolution of non-enlargement regions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the number of views in multiview images is increased, then the 3D display capability is improved, but the resolution per view deteriorates

Engineering Contradiction:
Improvenumber of viewsVSAvoidresolution per view
Core Design Contradiction:
Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The patent divides the image processing into different regions: a first region (enlargement target) and a second region (non-enlargement). This segmentation allows different resolution treatments for different parts of the multiview image, enabling selective enlargement of specific views or regions while maintaining other views at original resolution, thus resolving the contradiction between number of views and resolution per view

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent applies different quality levels to different regions of the multiview image. The first region is enlarged with higher resolution while the second region maintains original resolution. This local quality approach allows important regions to have high resolution while other regions consume less bandwidth, resolving the contradiction between enhancing specific views and maintaining overall multiview capability

Inventive Principle:
Principle #3Local quality

2Measurement precision

If image enlargement is performed in 3D display, then the visibility of details is improved, but the resolution deteriorates

Engineering Contradiction:
Improvevisibility of detailsVSAvoidresolution
Core Design Contradiction:
Measurement precisionVSManufacturing precision

Solution Approach 1:

The patent dynamically adjusts the resolution of different regions based on enlargement requirements. The first region is dynamically enlarged with adjusted resolution while the second region maintains static original resolution. This dynamic approach allows detail enhancement where needed while preserving overall resolution efficiency

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent changes the resolution parameter selectively for different regions. The first region undergoes parameter change (enlargement with adjusted resolution) while the second region maintains original parameters. This selective parameter change resolves the contradiction by improving detail visibility in specific regions without compromising overall resolution

Inventive Principle:
Principle #35Parameter changes

AI summary

Provided are an image magnification apparatus and method for three-dimensional display images. A multi-view image magnification apparatus includes: a region designation detection unit for detecting detection regions corresponding to the magnification regions of three-dimensional display images from original view images; a magnification ratio determination unit for determining the magnification ratios of the magnification regions; and a partial multiplexing unit for multiplexing non-detection regions except for the detection regions of the original view images according to a predetermined resolution and multiplexing the detection regions according the resolution which is different from the resolution of the non-detection regions on the basis of the magnification ratios. The present invention can magnify the images without lowering the resolution in a three-dimensional display.
