Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices with multiple cameras typically operate in a camera switching mode, preventing simultaneous data acquisition from multiple cameras, which limits synchronized data processing and presentation.
Innovation Solution
A video processing method and apparatus that controls multiple camera units to acquire and process video data simultaneously, using a single control unit to select a basic camera unit, correct video data from other units based on its information, and display the processed result, incorporating image stabilization, deblurring, and denoising techniques.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If multiple cameras operate in camera switching mode, then device complexity is reduced, but simultaneous data acquisition capability deteriorates
Solution Approach 1:
The patent merges the control functions of multiple cameras into a single control unit that can simultaneously manage all camera units. This allows multiple cameras to operate concurrently without requiring separate control systems for each camera, thus maintaining low device complexity while enabling simultaneous data acquisition from all camera units.
Solution Approach 2:
The control unit is designed with multi-functionality to handle multiple camera units simultaneously. It can select different camera units as basic camera units based on different scenarios and perform various processing operations (image stabilization, deblurring, denoising) on video data from multiple cameras, achieving both simplicity and simultaneous acquisition capability.
2Measurement precision
If multiple motion sensors are used for each camera unit, then video processing accuracy is improved, but power consumption increases
Solution Approach 1:
The patent combines the motion sensing function into a single motion sensor that serves all camera units. The motion sensor acquires basic information about the basic camera unit, and this information is then used by the control unit to process video data from all camera units, eliminating the need for multiple motion sensors and reducing power consumption while maintaining processing accuracy.
Solution Approach 2:
The system uses the motion information from the single motion sensor to self-adjust and correct video data from multiple camera units through image stabilization, deblurring, and denoising processing. This self-service mechanism allows accurate video processing without requiring additional sensors for each camera.
3Measurement precision
If multiple information acquisition units are used, then processing accuracy is improved, but device complexity increases
Solution Approach 1:
The control unit is designed as a universal information processing center that can handle data from all camera units using information from the single motion sensor. It performs multiple processing functions including selecting basic camera units, correcting video data, and coordinating all camera operations, thereby maintaining high processing accuracy without increasing device complexity through multiple acquisition units.
