Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image processing technologies on mobile terminals limit users to single-camera shooting effects, restricting creative possibilities and user experience in capturing and sharing content.
Innovation Solution
An image processing method and apparatus that utilize two photographing devices (e.g., front and rear cameras) to automatically switch between them based on preset conditions, allowing for dynamic display and capture of video images, enhancing creative options and user interaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single camera is used for shooting, then the device structure is simple and easy to operate, but the photographing creativity and content variety are limited
Solution Approach 1:
The system automatically detects the subject in the video image and autonomously switches between cameras based on preset conditions, eliminating the need for manual camera switching operations. The terminal performs self-service by autonomously determining when to switch from the first camera to the second camera based on subject detection and condition evaluation.
Solution Approach 2:
The terminal is equipped with multiple photographing devices (first camera and second camera) that serve different shooting functions. The system can selectively use different cameras based on the shooting scenario, providing universal adaptability for various photographing needs such as front-facing selfies, rear-facing landscape shots, and creative switching effects.
2Adaptability or versatility
If manual camera switching is implemented, then photographing flexibility is improved, but the operation complexity and user burden increase
Solution Approach 1:
The system automatically detects the subject in the video image and autonomously switches between cameras based on preset conditions, eliminating the need for manual camera switching operations. The terminal performs self-service by autonomously determining when to switch from the first camera to the second camera based on subject detection and condition evaluation.
Solution Approach 2:
The system continuously monitors the video image for subject detection and automatically adjusts camera switching based on detected conditions. The feedback mechanism evaluates whether preset switching conditions are met and triggers automatic camera switching accordingly, creating a closed-loop control system that adapts to shooting scenarios in real-time.
3Productivity
If automatic camera switching is implemented, then photographing efficiency and creativity are improved, but the system complexity and detection requirements increase
Solution Approach 1:
The system continuously monitors the video image for subject detection and automatically switches cameras based on detected conditions. The feedback mechanism evaluates whether preset switching conditions are met and triggers automatic camera switching accordingly, creating a closed-loop control system that adapts to shooting scenarios in real-time.
Solution Approach 2:
The system pre-sets switching conditions and detection parameters before actual shooting begins. By establishing detection thresholds and switching criteria in advance, the system prepares the detection framework beforehand, reducing the complexity of real-time decision-making and improving photographing efficiency.
