Camera Settings Switching for Simultaneous VLC and AR
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current devices for image-based services, such as those using Visible Light Communication (VLC), are limited in their ability to simultaneously enable VLC and other image-based services like Augmented Reality due to incompatible camera settings, which restrict their application and efficiency.
Innovation Solution
A device with a camera that periodically switches between two sets of camera settings: one optimized for VLC and another for other image-based services, allowing for adaptive framerate and exposure time adjustments based on detected characteristics or sensor inputs to accommodate both services with a single camera.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the camera uses settings optimized for Visible Light Communication detection, then VLC detection capability is improved, but other image-based services like Augmented Reality cannot be performed accurately
Solution Approach 1:
The camera settings are made dynamic by periodically switching between different configuration groups. The processor controls the camera to alternate between first camera settings (optimized for VLC detection with underexposure and high ISO) and second camera settings (optimized for other image-based services with overexposure and low ISO), enabling the system to adapt its characteristics based on the required function.
Solution Approach 2:
The system implements periodic switching between different camera setting groups to capture frames alternately optimized for VLC detection and other image-based services. This periodic action allows both functions to operate with appropriate settings during their respective time slots, resolving the contradiction between specialized performance and general compatibility.
2Manufacturing precision
If the camera uses settings optimized for other image-based services, then image quality for services like Augmented Reality is improved, but Visible Light Communication detection is hindered
Solution Approach 1:
The camera settings are made dynamic by periodically switching between different configuration groups. The processor controls the camera to alternate between first camera settings (optimized for VLC detection with underexposure and high ISO) and second camera settings (optimized for other image-based services with overexposure and low ISO), enabling the system to adapt its characteristics based on the required function.
Solution Approach 2:
The system implements periodic switching between different camera setting groups to capture frames alternately optimized for VLC detection and other image-based services. This periodic action allows both functions to operate with appropriate settings during their respective time slots, resolving the contradiction between specialized performance and general compatibility.
3Device complexity
If a single camera is used for both VLC detection and other image-based services, then device complexity is reduced, but the camera cannot simultaneously perform both functions effectively
Solution Approach 1:
A single camera is designed to perform multiple functions by switching between different setting groups. The camera serves both as a VLC detection device and an image capture device for other services, eliminating the need for separate dedicated cameras while maintaining effectiveness in both functions through periodic reconfiguration.
Solution Approach 2:
The camera settings are made dynamic by periodically switching between different configuration groups. The processor controls the camera to alternate between first camera settings (optimized for VLC detection with underexposure and high ISO) and second camera settings (optimized for other image-based services with overexposure and low ISO), enabling the system to adapt its characteristics based on the required function.
4Productivity
If the camera captures continuous video frames for image-based services, then service responsiveness is improved, but energy consumption increases
Solution Approach 1:
The system implements periodic switching between different camera setting groups to capture frames alternately optimized for VLC detection and other image-based services. This periodic action allows both functions to operate with appropriate settings during their respective time slots, resolving the contradiction between specialized performance and general compatibility.
Solution Approach 2:
Instead of continuously capturing high-quality frames for all services, the system captures frames periodically with settings optimized for the current priority function. During VLC detection phases, frames are captured with VLC-optimized settings even if image quality is reduced, and vice versa, accepting partial functionality at any given moment to maintain overall system efficiency.
