Solution Overview
Problem
Electronic devices lack sufficient lighting for front cameras, which can lower the quality of pictures taken, as they typically do not have flashlights like rear cameras do.
Innovation Solution
An electronic device with a display that adjusts color temperature and brightness to provide optimal lighting for front camera usage, using a color temperature determining module, brightness determining module, and sensors to analyze and adjust the light output based on preset values for improved image capture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If flash lights are installed for the back camera, then the lighting quality for back camera is improved, but the front camera still lacks sufficient lighting
Solution Approach 1:
The display screen is designed to serve dual functions: as a user interface display and as a flash light for front camera selfies. By controlling the display to emit light in front camera mode, the system provides illumination for the front camera without requiring a separate flash light component, thus achieving multi-functionality and resolving the lighting coverage issue.
2Adaptability or versatility
If the display is used to provide light for front camera, then the lighting coverage is improved, but the color temperature and brightness need precise control to maintain image quality
Solution Approach 1:
The system employs feedback mechanisms through color temperature sensors and brightness sensors that detect the ambient light conditions and the actual light output from the display. This feedback is processed by the processor to automatically adjust the display's color temperature and brightness, ensuring precise control and maintaining image quality while providing adequate illumination for front camera selfies.
Solution Approach 2:
The system dynamically changes the display's operating parameters (color temperature and brightness) based on ambient light conditions and camera mode. By adjusting these parameters in real-time, the system optimizes the display's light output for different shooting scenarios, achieving precise color temperature control without compromising lighting coverage.
3Device complexity
If ambient light is used for front camera, then no additional light source is needed, but the lighting quality is insufficient in low light conditions
Solution Approach 1:
The display screen serves itself by providing illumination for front camera selfies when needed. Instead of requiring a separate flash light component, the system utilizes the display's existing light-emitting capability, controlled by the processor based on shooting mode detection. This self-service approach reduces device complexity while maintaining adequate lighting quality through intelligent control.
