Stereoscopic Image Partial Enhancement via Region-Specific Parallax Shift
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image display technologies cannot partially adjust the stereoscopic sensation of images, limiting the ability to enhance specific areas of a stereoscopic image.
Innovation Solution
An image display apparatus and method that adjust the parallax between left and right eye images using different amounts of adjustment for instructed and non-instructed areas, allowing for partial enhancement of a desired area by shifting the image positions accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the positional relationship between left eye image and right eye image is changed to adjust stereoscopic sensation, then the stereoscopic sensation of the entire image is adjusted, but partial adjustment of stereoscopic sensation in a desired position cannot be achieved
Solution Approach 1:
The image is divided into multiple regions (first region and second region) with different parallax adjustment characteristics. The image generation unit applies different horizontal shift amounts to different regions, enabling independent control of stereoscopic sensation in each region. This segmentation allows partial adjustment of stereoscopic sensation in desired positions while maintaining other regions unchanged.
Solution Approach 2:
Different regions of the image are assigned different parallax adjustment properties. The first region has a different horizontal shift amount compared to the second region, creating local variations in stereoscopic sensation. This allows specific areas to be enhanced with stronger or weaker parallax effects according to display requirements.
2Reliability
If uniform parallax adjustment is applied to the entire image, then the stereoscopic sensation is consistently adjusted across all areas, but the ability to guide viewer attention to specific areas is lost
Solution Approach 1:
The image is segmented into regions with different parallax adjustment characteristics. By assigning different horizontal shift amounts to different regions, the system can guide viewer attention to specific areas of interest while maintaining reliable stereoscopic sensation in other regions. This segmentation enables selective enhancement of important display areas.
Solution Approach 2:
The horizontal shift amount parameter is varied across different image regions. The image generation unit changes the parallax parameter (horizontal shift amount) depending on the region, allowing certain areas to have enhanced stereoscopic effects that attract viewer attention while other areas maintain standard parallax for consistent depth perception.

AI summary
When a user instructs a control unit about a position in a substantially central portion of an illustration with an electronic pen, the control unit determines a rectangular area that surrounds the illustration as an enhancement area. An image adjustment unit carries out a process of shifting the portion in the enhancement area in an image for the left eye rightward by a predetermined amount and shifting the portion in the enhancement area in an image for the right eye leftward by a predetermined amount. As a result, the illustration located in the enhancement area is so changed that the image for the left eye is shifted to a position to the right of the image for the right eye and hence recognized as if the illustration were located in front of other illustrations. The illustration in the enhancement area is thus enhanced.
