Image Processing Apparatus Viewpoint-Aware Display Distortion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display systems that generate wide-field images often result in unnatural distortion and discomfort for viewers due to insufficient consideration of the viewer's viewpoint position, leading to inadequate adjustment of the image processing to match the display angle.
Innovation Solution
An image processing apparatus that acquires the imaging angle of view and display system information to generate a display image by establishing a correspondence relationship between a projection plane and the display portion in a virtual space, using a display angle parameter to adjust the image accordingly, thereby minimizing distortion and discomfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If image processing for widening the angle of view is executed without considering the viewpoint position, then the display angle requirement is satisfied, but unnatural distortion occurs and viewer comfort deteriorates
Solution Approach 1:
The patent changes the parameter of viewpoint position from being ignored to being explicitly considered in the image processing. By adjusting the viewpoint position parameter to coincide with the center of the display portion, the system achieves both wide display angle coverage and natural image appearance without distortion
Solution Approach 2:
The patent introduces a virtual space dimension that incorporates three-dimensional spatial relationships between the display portion and the viewpoint. This allows the system to map the flat captured image to the curved display surface while maintaining proper perspective relationships, resolving the distortion issue
2Area of stationary object
If a flat image is mapped to spherical shape to display on wide viewing angle screen, then the display system can cover the field of vision, but the viewpoint position information is lost causing discomfort
Solution Approach 1:
The patent performs preliminary action by setting the viewpoint position in advance before generating the display image. The viewpoint position is predetermined to coincide with the center of the display portion, ensuring that perspective information is preserved throughout the mapping process from flat image to spherical display surface
Solution Approach 2:
The patent creates a virtual copy of the captured image in a virtual space that maintains the original viewpoint information. This virtual image copy is then mapped to the display portion, preserving spatial relationships and avoiding the information loss that occurs with direct flat-to-spherical mapping

AI summary
An image processing apparatus includes a first acquisition unit configured to acquire an imaging angle of view at which an input image is captured, a second acquisition unit configured to acquire display system information indicating, in a display system including a display portion, a display angle, which is a visual angle at which the display portion is viewed from a viewpoint position, and a generation unit configured to, using a correspondence relationship between a projection plane and the display portion in a virtual space based on the imaging angle of view and the display system information, generate a display image to be displayed on the display portion.
