Curved Display Pixel Positioning for Immersive Projection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
To provide a planar image with a high sense of realism and immersion, a large flat screen is typically required, which consumes significant space.
Innovation Solution
An image processing apparatus and projection system that calculate and display/project pixels on a curved surface based on the positional relationship between a viewpoint position and a virtual surface, allowing the planar image to be projected without distortion on a dome-shaped screen, reducing the required space.

Engineering Contradiction Analysis
1Ease of manufacture
If a large flat screen is used to provide planar image content with a high sense of realism and immersion, then the sense of realism and immersion is improved, but the required space increases
Solution Approach 1:
The patent applies curvature by projecting planar image content onto a dome-shaped curved screen instead of using a large flat screen. The projection system calculates pixel positions on the curved surface based on the positional relationship between the viewpoint and a virtual flat surface, enabling immersive content delivery while reducing the physical space required compared to a flat screen of equivalent immersive quality.
2Area of stationary object
If planar image content is projected on a curved surface, then the required space is reduced, but image distortion occurs
Solution Approach 1:
The patent changes the parameter of pixel positioning by calculating and adjusting the position of each pixel on the curved display surface based on the positional relationship between the viewpoint position and the virtual flat surface. This parameter transformation ensures that planar image content is projected onto the curved dome screen without distortion, maintaining image quality while reducing the required space.

AI summary
An image processing apparatus, an image processing method, and a projection system are provided. The image processing apparatus according to one embodiment includes a calculating section which, on the basis of a positional relationship between a viewpoint position set in front of a curved display surface and a virtual surface set behind the display surface, calculates the positions of respective pixels on the display surface, the pixels being included in a planar image generated on the assumption that the planar image is displayed on a plane, and displays the planar image on the display surface such that the respective pixels are displayed at the calculated positions.
