Spherical Venue Image Projection with Bottom Quality Focus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional ultra-wide-angle lenses, such as fisheye lenses, produce strong visual distortion and result in varying optical image quality across a three-dimensional media plane, with the lowest quality at the bottom, disrupting the viewer's experience during events as they must look up to see high-quality images, losing sight of performers.
Innovation Solution
An image capture system that focuses light rays onto the periphery of an image sensor and distributes them non-uniformly, combined with an image projection system using kernel-based sampling techniques to interpolate color information, ensuring high optical quality is maintained at the bottom of the three-dimensional media plane, allowing viewers to see high-quality images of performers without losing their view.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If conventional ultra-wide-angle lens is used to capture images for three-dimensional media plane, then hemispherical images can be produced, but optical image quality varies significantly across the display surface with lowest quality at the bottom
Solution Approach 1:
The patent applies local quality by capturing multiple images with different fields of view and selectively mapping regions of interest from each image to different zones of the three-dimensional media plane. High-quality central regions are mapped to the bottom where performers are displayed, while peripheral regions are mapped to upper zones, ensuring each zone receives optimally quality-matched content.
Solution Approach 2:
The patent segments the field of view into multiple regions with different quality characteristics and processes each region separately. The central high-quality region is extracted and mapped to the bottom display area, while peripheral lower-quality regions are mapped to upper areas, creating a segmented quality distribution that matches the spherical geometry.
2Manufacturing precision
If images are displayed with prime viewing section at the top, then highest optical image quality is achieved at the top, but audience must look up to see high-quality images causing performers to be out of view
Solution Approach 1:
The patent inverts the conventional quality distribution by placing the prime viewing section with highest optical quality at the bottom of the three-dimensional media plane instead of at the top. This allows audience members to view high-quality images of performers in their natural forward-facing field of view without needing to look upward.
3Area of stationary object
If conventional fisheye lens captures entire hemispherical view, then complete scene coverage is achieved, but image quality at the bottom is lowest due to optical distortion
Solution Approach 1:
The patent applies local quality by capturing multiple images with different fields of view and selectively mapping regions of interest from each image to different zones of the three-dimensional media plane. High-quality central regions are mapped to the bottom where performers are displayed, while peripheral regions are mapped to upper zones, ensuring each zone receives optimally quality-matched content.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution ensures that the audience experiences high optical image quality throughout the event, particularly at the bottom of the three-dimensional media plane, allowing them to view performers clearly while maintaining the highest image quality without needing to shift their gaze.

AI summary
Systems, methods, and apparatuses disclosed herein can include an exemplary image capture system to capture light that is related to an image within its field of view and/or an exemplary image projection system to transform the image for projection onto a three-dimensional media plane of a three-dimensional venue. The exemplary image capture system can direct rays of light that were captured by the exemplary image capture system onto an image sensor that is associated with the exemplary image capture system. As to be described in further detail below, the exemplary image capture system can focus these rays of light toward a periphery, or edge, of the image sensor. As a result, the three-dimensional venue can display the highest optical image quality for the image toward a bottom, or a springing, of the three-dimensional media plane. Moreover, the exemplary image capture system can be specifically manufactured to heterogeneously, for example, non-uniformly, distribute the rays of light that were captured by the exemplary image capture system onto the image sensor to further enhance the highest optical image quality for the image. As to be described in further detail below, the exemplary image projection system can project the image onto the three-dimensional media plane of the three-dimensional venue. As part of this projecting, the exemplary image projection system can mathematically transform two-dimensional coordinates of pixels of the image onto three-dimensional coordinates of the three-dimensional media plane to project the image onto the three-dimensional media plane. And as part of this projecting, the exemplary image projection system can statistically interpolate color information that is to be projected onto the three-dimensional media plane from the image.
