Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing camera systems for generating parallax images in head-mounted displays face challenges with increased apparatus size due to multiple cameras needing to face the same direction and difficulty in acquiring parallax of moving objects when one camera is rotated.
Innovation Solution
A camera system with multiple cameras configured to capture images in different directions, a drive section for rotating the cameras, and a parallax acquisition section to detect parallax information from specific regions, allowing for the generation of suitable three-dimensional images.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple cameras are used to capture images of the same subject, then parallax images can be generated, but the apparatus size increases
Solution Approach 1:
The patent transitions from capturing images in the same direction to capturing images in different spatial directions using multiple cameras positioned at different orientations. This dimensional arrangement allows parallax acquisition without requiring multiple cameras to face the same direction, thereby reducing apparatus size while maintaining parallax image quality
Solution Approach 2:
The camera system is designed to perform multiple functions: capturing images in different directions simultaneously, rotating to track moving objects, and generating parallax images. This multi-functionality allows a single integrated system to replace what would otherwise require separate specialized devices, reducing overall apparatus size
2Area of stationary object
If one camera is rotated to generate parallax images, then apparatus size is reduced, but acquiring parallax of moving objects becomes difficult
Solution Approach 1:
The camera system incorporates dynamic rotation capability that adapts to moving objects. The drive section rotates the cameras in real-time to track moving objects, ensuring continuous parallax acquisition. This dynamic adjustment maintains measurement precision for moving objects while keeping the apparatus compact
Solution Approach 2:
The system maintains continuous parallax acquisition through ongoing rotation and image capture. By continuously rotating the cameras and capturing images in different directions, the system ensures uninterrupted parallax data collection for moving objects, maintaining measurement precision without requiring a large stationary apparatus
3Measurement precision
If multiple cameras face the same direction, then parallax images can be captured, but the arrangement complexity increases
Solution Approach 1:
The patent employs asymmetric camera arrangements where cameras are positioned at different orientations and angles rather than symmetrically facing the same direction. This asymmetric configuration simplifies the overall arrangement by eliminating the need for complex alignment mechanisms while still capturing the necessary parallax information for image quality

AI summary
A camera system includes a plurality of cameras configured to capture images in different directions. The camera system rotates the plurality of cameras in a predetermined direction. The plurality of cameras are configured such that, even during rotation, one of the cameras captures an image of a preset specific region. The camera system acquires parallax information regarding an object present in the specific region on the basis of a plurality of captured images of the specific region.
