Solution Overview
Problem
Video communication quality is compromised in low light conditions, leading to poor image clarity and excessive energy consumption, as existing systems continue to capture and process unclear video images.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the terminal continues to capture real-time video images in low light conditions, then the video communication function is maintained, but the image quality becomes poor and energy is wasted
Solution Approach 1:
The patent dynamically adjusts the image acquisition mode based on real-time light intensity detection. When light intensity is sufficient, the system uses real-time video capture; when light intensity is insufficient, it switches to using a preset image. This dynamic adaptation resolves the contradiction by maintaining video communication functionality while avoiding energy waste in low light conditions.
Solution Approach 2:
The terminal automatically detects light intensity and switches between real-time video capture and preset image mode without user intervention. The system serves itself by monitoring environmental conditions and making appropriate adjustments, thereby maintaining communication reliability while reducing energy consumption in low light scenarios.
2Reliability
If the terminal captures real-time video images in low light conditions, then the video communication function is maintained, but the image quality becomes poor
Solution Approach 1:
The system dynamically switches between real-time video capture and preset image mode based on light intensity conditions. When light is insufficient, it transitions to preset image mode to avoid poor image quality, while still maintaining the video communication function through the stored image.
Solution Approach 2:
The terminal captures and stores a preset image in advance under normal lighting conditions. This preliminary action ensures that when light intensity becomes insufficient during video communication, a quality image is already available for use, avoiding the need to capture poor quality images in low light.
3Loss of energy
If the terminal uses light intensity detection to switch between real-time video capture and preset image, then energy is saved and image quality is maintained, but the system complexity increases
Solution Approach 1:
The terminal integrates multiple functions into a unified system: light intensity detection, automatic mode switching between real-time video capture and preset image, and video communication. This multi-functionality achieves energy savings and image quality maintenance while managing system complexity through integration rather than separate components.
Solution Approach 2:
The system performs automatic light intensity detection and mode switching without requiring additional user interface elements or complex control mechanisms. The self-service nature of the automation simplifies the user experience while managing system complexity through intelligent algorithms rather than hardware complexity.
