Multiview Camera Array With Shared Sub-Arrays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic displays, particularly passive displays like LCDs and EP displays, lack the ability to emit light, limiting their practical applications, and image processing for 3D image capture involves complex and time-consuming processes that delay image display.
Innovation Solution
A multiview camera array with multiple camera sub-arrays having different baseline spacings captures images from various angles, producing a multiview image that can be displayed on a multiview display, providing a 3D viewing experience by sharing cameras between sub-arrays to reduce cost and power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple camera sub-arrays with different baseline spacings are used to capture multiview images, then the 3D viewing experience and image quality are improved, but the system cost and power consumption increase
Solution Approach 1:
The patent implements camera sharing across multiple sub-arrays, where each camera serves multiple sub-arrays with different baseline spacings. This multi-functionality allows the system to achieve diverse multiview capture capabilities while reducing the total number of cameras, thereby lowering power consumption and system cost.
Solution Approach 2:
The patent combines multiple camera sub-arrays with different baseline configurations into a unified multiview system. By merging the functionality of separate camera systems and allowing shared camera resources, the system achieves improved 3D image quality without proportionally increasing power consumption.

If complex image processing is performed to convert 2D images into 3D images, then the 3D viewing experience is achieved, but the processing time and delay increase
Solution Approach 1:
The patent performs depth estimation and 3D image reconstruction in real-time as images are captured from multiple viewpoints. By conducting image processing operations concurrently with capture and using optimized algorithms, the system minimizes processing delay while maintaining 3D viewing capability.

AI summary
A multiview camera array and multiview system employ camera sub-arrays having at least one camera in common to capture a multiview image of a scene for display on a multiview display. The multiview camera array includes a first sub-array of cameras and a second sub-array of cameras. Cameras of the first and second camera sub-arrays are spaced apart from one another by a first baseline distance and a second baseline distance, respectively. The multiview system further includes a multiview display configured to display the multiview image. A method of capturing a multiview image includes capturing a first plurality of different views of the scene with the first sub-array of cameras and capturing a second plurality of different views of the scene using the second sub-array of cameras.
