Display Fill Light Region for Video Conferencing Illumination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional Information Handling Systems (IHSs) face challenges in providing adequate illumination for users during videoconferencing and vlogging, especially in low ambient lighting conditions, requiring external and cumbersome lighting sources that increase costs and complexity.
Innovation Solution
The system generates a fill light region on the IHS display using a camera to enhance user illuminance, eliminating the need for additional lighting sources by manipulating the display's light output and adjusting it based on ambient conditions and user input.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If external lighting sources are used to illuminate users during videoconferencing, then user illumination is improved, but device complexity and cost increase
Solution Approach 1:
The patent merges the display function and lighting function into a single component. The display screen serves dual purposes: displaying visual content and providing fill light illumination for the user during videoconferencing. This eliminates the need for separate external lighting sources, reducing device complexity while maintaining illumination benefits
Solution Approach 2:
The display is designed to perform multiple functions simultaneously. During videoconferencing, it acts as both the visual output device and the illumination source. The system can dynamically adjust the display's functionality based on ambient light conditions and camera detection, making the display a universal component that adapts to different operational requirements
2Illumination intensity
If external lighting sources are used to illuminate users during videoconferencing, then user illumination is improved, but cost increases
Solution Approach 1:
By combining the display and lighting functions into one component, the patent eliminates the need to manufacture and assemble separate lighting hardware. This reduces bill of materials costs, assembly complexity, and overall manufacturing expenses while providing the same illumination benefit
Solution Approach 2:
The system uses the existing display's light output as a copy of traditional lighting functionality. Instead of creating a new lighting subsystem, the patent leverages the display's inherent light-emitting capability to replicate the function of external lights, reducing manufacturing costs
3Illumination intensity
If display light output is increased to provide fill light, then user illuminance is improved, but display quality for viewing may deteriorate
Solution Approach 1:
The patent segments the display's light output into different functional zones or time periods. During videoconferencing when the camera is active, the display provides enhanced illumination. During normal viewing, the display maintains optimal image quality. The system dynamically switches between these modes based on camera detection and ambient light conditions
Solution Approach 2:
The display's illumination function is dynamically controlled based on real-time conditions. The system monitors ambient light levels and camera activity, adjusting the display's light output accordingly. This dynamic control ensures that illumination is enhanced only when needed for videoconferencing, while display quality is maintained during regular viewing
