TV Makeup Mode White Background Illumination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional makeup mirrors often lack consistent and correct color temperature lighting, which can impair judgment on how makeup will appear in varying ambient conditions.
Innovation Solution
A video display device, such as a TV, equipped with a processor, camera, and a computer-readable storage medium, presents a viewer's image with a white background of predetermined color temperature and brightness, allowing for real-time illumination and adjustable lighting conditions to mimic different ambient settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If crude filters or lamps are added to correct color temperature, then lighting accuracy is improved, but device complexity increases
Solution Approach 1:
The video display device serves dual functions: it displays visual content and simultaneously provides illumination with accurate color temperature for makeup application. The display itself acts as both the mirror surface and the lighting source, eliminating the need for separate lighting components.
Solution Approach 2:
The system dynamically adjusts the color temperature and brightness parameters of the display to simulate different ambient lighting conditions. This allows accurate color representation without adding physical filters or lamps, as the display can directly emit light at the required color temperatures.
2Ease of operation
If ambient lighting is used for makeup application, then ease of operation is improved, but lighting consistency deteriorates
Solution Approach 1:
The display is configured to present an all-white background image with controlled brightness and color temperature parameters. This creates consistent, stable lighting conditions that remain unchanged regardless of ambient lighting variations, while maintaining simple operation through automatic activation in makeup mode.
Solution Approach 2:
The system proactively establishes controlled lighting conditions by displaying a white background before the user begins makeup application. This preliminary action ensures that the lighting environment is optimized and consistent before the user needs to evaluate makeup appearance.
3Adaptability or versatility
If video display is used to provide illumination, then device versatility is improved, but energy consumption increases
Solution Approach 1:
The video display device integrates multiple functions including content display, makeup mirror, and controlled illumination source. By using the existing display hardware for illumination, the system avoids adding separate lighting components that would increase energy consumption, leveraging the display's built-in backlighting capabilities.

Data Source
AI summary
A TV has a makeup mode in which a camera on the TV images a viewer of the TV and presents the viewer's image on the TV. To illuminate the viewer, the TV also juxtaposes with the viewer's image an all-white background image having a known color temperature and brightness.
