Stereoscopic Display Using Spatial Image Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional stereoscopic image display technologies are costly and unnatural due to the need for generating parallax images, which can cause a mismatch in convergence and adjustment of sight, resulting in an unnatural viewing experience.
Innovation Solution
An image processing apparatus that generates left and right images by shifting a two-dimensional image within a display region, ensuring these images are not displayed together within the user's effective field of vision, allowing each eye to see its respective image, thus eliminating the parallax effect and providing a more natural stereoscopic view.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If parallax images are generated using two or more cameras arranged and controlled appropriately, then stereoscopic viewing is achieved, but the cost increases significantly
Solution Approach 1:
The patent divides the display region into multiple sub-regions, with each sub-region displaying a different image (left-eye image, right-eye image, or depth information) to correspond with different eye regions. This segmentation allows a single camera to provide stereoscopic viewing by spatially separating the image content for each eye, eliminating the need for multiple cameras and reducing cost while maintaining the stereoscopic viewing capability.
2Adaptability or versatility
If parallax images are generated by displaying multiple images captured at different times to the right eye and left eye, then stereoscopic effect is achieved, but complex manual operations and judgments by the user are required
Solution Approach 1:
The patent enables the display apparatus to automatically generate and display depth information without requiring user intervention. The system uses a single camera to capture images and automatically processes them into left-eye and right-eye images with appropriate depth information, eliminating the need for users to perform complex manual operations or judgments while maintaining the stereoscopic effect.
3Adaptability or versatility
If conventional stereoscopic viewing technology is used, then parallax effect is achieved, but the object appears unnatural due to mismatch between convergence and adjustment of sight
Solution Approach 1:
The patent applies different image content to different spatial regions of the display corresponding to different eye regions. By displaying depth information in specific sub-regions and left/right eye images in corresponding sub-regions, the system maintains proper convergence and adjustment alignment for each eye, eliminating the mismatch that causes unnatural appearance while preserving the parallax effect.
4Adaptability or versatility
If two images are generated to create parallax effect when viewed from a single location, then stereoscopic image is achieved, but high cost is incurred for capturing and processing
Solution Approach 1:
The patent segments the display region into multiple sub-regions that can be independently controlled to display different images. This allows a single camera to provide stereoscopic viewing by spatially separating the image content for each eye, eliminating the need for multiple cameras and reducing the complexity and cost of capturing and processing while maintaining the stereoscopic image capability.

AI summary
Provided is an image processing apparatus that stereoscopically displays a two-dimensional image, comprising a generating section that generates a left-side image and a right-side image by shifting the two-dimensional image left and right in a display region; and an output section that outputs the left-side image to a left eye of the user and the right-side image to a right eye of the user. The generating section generates the left-side image and the right-side image by shifting the two-dimensional image to the left and right within the display region by a distance no greater than a distance between pupils of a user.
