Stereoscopic Display System Using Segmented Eye Channels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional stereoscopic image display systems require wearing glasses, limiting the viewer's ability to see the surrounding environment, restrict movement, and make it difficult to share the same stereoscopic image between multiple people, while also lacking a sense of reality and flexibility.
Innovation Solution
An image display system that uses a combination of real and virtual image presentation units, where a real image is viewed with one eye and a virtual image, generated based on a code image or parallax differences, is displayed with the other eye, allowing for flexible stereoscopic viewing without the need for glasses and enabling awareness of the external world.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If special glasses are used for stereoscopic viewing, then stereoscopic image quality is improved, but the viewer cannot see surrounding circumstances and movement is restricted
Solution Approach 1:
The patent divides the viewing experience into two separate channels: one eye views the real physical world directly, while the other eye views a virtual stereoscopic image through a display device. This segmentation allows each eye to perform its function independently, resolving the contradiction between immersive stereoscopic viewing and environmental awareness.
Solution Approach 2:
The patent introduces a camera as an intermediary device that captures the real-world scene and transforms it into a virtual image displayed to one eye. This intermediary allows the viewer to see both the actual environment (with one eye) and a processed virtual representation (with the other eye), maintaining awareness while enabling stereoscopic effects.
2Measurement precision
If special glasses are required for stereoscopic viewing, then stereoscopic effect is achieved, but sharing the same image between multiple persons becomes difficult
Solution Approach 1:
The patent uses a camera to create a copy of the real-world scene, which is then displayed as a virtual image to one eye while the other eye sees the actual scene. This copying mechanism allows the stereoscopic effect to be generated from a captured image that can be shared or reproduced, enabling multiple viewers to experience the same stereoscopic content without requiring specialized glasses.
3Adaptability or versatility
If the viewing person moves from the predetermined position, then flexibility is improved, but physiological sense of discomfort arises in conventional systems
Solution Approach 1:
The patent implements dynamic adjustment of the virtual image display based on the viewer's movement. The system continuously tracks the viewer's position and adjusts the virtual image accordingly, allowing flexible movement while maintaining viewing comfort. This dynamic adaptation resolves the contradiction between movement freedom and viewing stability.

AI summary
An image display system, an image display method, a coding method, and a printed matter for stereoscopic viewing are disclosed. The image display system includes a real image presentation unit for showing a first view image of the stereoscopic image as a real image, and a virtual image presentation unit for showing a second view image of the stereoscopic image as a virtual image, the second view image being based on the first view image. When the first view image is viewed by one eye of a viewing person, and the second view image is viewed by the other eye of the viewing person, the first view image and second view image together form the stereoscopic image.
