Curved Projection Plane for Multi-Screen Display Distortion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display systems using multiple flat screens to cover a viewer's field of view often result in unnatural image display due to spatial distortion and require multiple image capturing apparatuses with synchronized shooting parameters, making it cumbersome and inefficient.
Innovation Solution
An image processing method that generates display images for a system of flat screens by projecting an input image onto a curved projection plane, which is set based on the shape of the display area, allowing a single image capturing apparatus to capture an input image and generate images for multiple screens with consistent parameters.

Engineering Contradiction Analysis
1Area of moving object
If multiple flat display screens are placed to cover the field of view, then the wide-field display capability is improved, but spatial distortion occurs making the image unnatural
Solution Approach 1:
The patent applies curved projection planes instead of flat projection planes to match the curved field of view. By projecting the input image onto curved surfaces that correspond to the spherical display geometry, the patent eliminates spatial distortion and produces natural-looking wide-field images across multiple flat screens arranged in a spherical configuration.
2Manufacturing precision
If multiple image capturing apparatuses are used to capture images for each display screen, then the image quality for each screen is improved, but the system complexity and synchronization requirements increase
Solution Approach 1:
The patent uses a single image capturing apparatus that serves multiple functions by capturing one input image that is then processed and projected onto multiple curved projection planes corresponding to different display screens. This eliminates the need for multiple capturing apparatuses and their associated synchronization requirements, while still providing high-quality images for each screen.
Solution Approach 2:
The patent segments the single captured image into multiple projected images by applying different curved projection transformations to the same input image. Each display screen receives a processed version of the original image, tailored to its specific geometric position in the spherical arrangement, eliminating the need for multiple capturing devices.

AI summary
There is provided with an image processing apparatus that generates a display image to be displayed in a display system including a display area. An obtaining unit obtains one input image acquired through shooting by one image capturing apparatus. A generating unit generates the display image from the input image on the basis of a correspondence between a first projection plane corresponding to the input image and a second projection plane corresponding to the display area.
