Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current stereoscopic image display systems using multiple projectors with fixed positions cannot dynamically adjust the quality of three-dimensional images, limiting the visual experience due to fixed light beam directions and angles, which restricts the optimization of the stereoscopic effect, especially for large resolution images.
Innovation Solution
An image display system comprising a set of projectors and an auxiliary projector that generates additional light beams to increase perspective information, allowing dynamic adjustment of light beam directions and angles to enhance the stereoscopic effect within a visual field, thereby improving the quality of the three-dimensional image object.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple projectors with fixed positions are used to generate stereoscopic images, then perspective information can be provided for naked eye 3D effect, but the quality of three-dimensional image objects cannot be dynamically adjusted and visual experience cannot be optimized
Solution Approach 1:
The patent introduces a movable auxiliary projector that can dynamically adjust its position and projection angle, transforming the static projector array into a dynamic system. This allows the system to adapt to different viewing conditions and optimize the stereoscopic effect for various regions of the screen, resolving the contradiction between adaptability and device complexity.
Solution Approach 2:
The patent divides the projection system into a fixed projector array for basic stereoscopic function and a movable auxiliary projector for dynamic optimization. This segmentation allows the core system to remain simple while adding dynamic capabilities through the auxiliary component, addressing the contradiction between adaptability and complexity.
2Manufacturing precision
If a projector array is used for large resolution images, then images can be displayed on specific regions, but only a few projectors can generate three-dimensional image objects on certain regions limiting quality optimization
Solution Approach 1:
The movable auxiliary projector can dynamically reposition itself to project additional light beams onto specific regions of the screen where three-dimensional image objects are displayed. This dynamic allocation of projection resources enhances the quality of 3D image objects in specific regions without requiring a complete reconfiguration of the entire projector array.
Solution Approach 2:
The patent adds a new dimension of mobility to the traditional fixed projector array. The auxiliary projector can move along the screen surface or adjust its projection angle independently, providing additional perspective information from different angles and enhancing the three-dimensional image quality without increasing the number of fixed projectors.
3Ease of operation
If fixed position projectors are used, then system configuration is simple, but light beam directions and angles are fixed limiting stereoscopic effect optimization
Solution Approach 1:
The patent introduces a movable auxiliary projector that can dynamically adjust its position and projection parameters, transforming the static light beam configuration into a dynamic one. This allows the system to optimize the stereoscopic effect for different viewing conditions and screen regions while maintaining relative simplicity through the use of a single movable component rather than multiple fixed projectors.

AI summary
An image display system includes a set of projectors, a screen, and an auxiliary projector. The set of projectors is used for generating a plurality of light beams and projecting the plurality of light beams to a region of an image plane. The screen faces the set of projectors for providing the image plane in order to generate a three-dimensional image object by the plurality of light beams projected to the region of the image plane. The auxiliary projector is used for generating and projecting at least one additional light beam to the region of the image plane in order to increase perspective information of incident light of the three-dimensional image object on a view point within a visual field.
