Adjustable Stereo Camera Distance for Fatigue-Free Mobile Viewing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional stereoscopic cameras fail to provide an optimal stereoscopic effect across various display sizes, from small mobile devices to large screens, due to fixed camera distances that do not accommodate varying viewer distances and display sizes, leading to eye fatigue and inadequate stereoscopic experiences.
Innovation Solution
A mobile stereoscopic camera system that calculates and adjusts the distance between its left and right cameras based on focusing distance, focal length, and critical parallax, allowing for optimal stereoscopic image capture suitable for diverse display environments, including small mobile devices and large screens, using a method that involves determining the focusing distance and calculating the camera distance using specific equations to ensure a consistent stereoscopic effect.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the distance between two cameras is fixed to the distance between both eyes of a human being (about 65 mm), then the stereoscopic image can be viewed on large displays such as movie screens, but the stereoscopic image causes eye fatigue and headache when displayed on smaller displays such as mobile devices or personal computers
Solution Approach 1:
The patent makes the camera distance adjustable rather than fixed. The distance between the two cameras can be dynamically changed based on the display size and viewing conditions. For mobile devices, the camera distance is reduced to a smaller value, while for large movie screens, it is set to the standard 65 mm interocular distance, thereby adapting to different display environments and preventing eye fatigue
Solution Approach 2:
The patent changes the physical parameter of camera distance according to different display sizes. By adjusting this parameter, the system optimizes the stereoscopic effect for each display type - using a smaller camera distance for mobile devices and a larger distance for theater screens, thus resolving the contradiction between universal adaptability and viewing comfort
2Reliability
If a stereoscopic camera is designed for large movie screens, then optimal stereoscopic effect is achieved on large displays, but the same camera configuration fails to provide adequate stereoscopic effect on small mobile device displays
Solution Approach 1:
The patent creates a universal stereoscopic camera system that can function optimally across multiple display types. By incorporating an adjustable camera distance mechanism, a single camera system can serve both mobile devices and large movie screens, eliminating the need for different camera configurations for different display sizes
3Object-affected harmful factors
If the camera distance is reduced for mobile device displays, then comfortable viewing is achieved on small screens, but the stereoscopic image quality deteriorates when displayed on large movie screens
Solution Approach 1:
The system dynamically adjusts the camera distance based on the target display size. When configured for mobile devices, it uses a reduced camera distance to prevent eye fatigue. When configured for movie screens, it increases the camera distance to maintain optimal stereoscopic image quality, thus resolving the contradiction between comfort and quality
