Real-Time Makeup Image Brightness Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing virtual makeup technologies struggle to maintain a consistent and natural appearance when the brightness of the face changes, especially in outdoor settings, leading to a mismatch between the makeup image and the skin tone.
Innovation Solution
An image synthesis device that adjusts the brightness of the makeup image on a pixel basis in real-time to match the changing skin brightness, using a configuration including an imaging unit, a displayer, and a makeup image superimposing unit that calculates and applies new brightness and saturation values based on the skin's current brightness and reference values.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If virtual makeup is applied to Selphy images in real time, then users can see makeup effects immediately, but the brightness that illuminates the face often changes especially in outdoors and the synthesized makeup image and color of skin on the skin does not match when the brightness that illuminates the face changes
Solution Approach 1:
The patent applies dynamics by making the makeup image brightness adjustable and adaptable to changing lighting conditions. The system dynamically modifies the brightness of the makeup image based on the detected skin brightness, allowing the makeup effect to remain natural and matching under varying illumination conditions in real-time.
Solution Approach 2:
The patent changes the brightness parameter of the makeup image to match the skin brightness. By detecting the actual brightness of the user's skin and adjusting the makeup image brightness accordingly, the system ensures that the makeup effect remains visually consistent and natural even when lighting conditions change during real-time application.
2Reliability
If the brightness of the makeup image is adjusted to match changing skin brightness, then the makeup image remains natural and matching, but additional processing is required every time skin brightness changes
Solution Approach 1:
The patent implements feedback by continuously detecting the skin brightness and using this information to adjust the makeup image brightness. The system monitors changes in skin brightness and automatically modifies the makeup image accordingly, creating a closed-loop control system that maintains natural appearance without requiring complex manual intervention.
Solution Approach 2:
The system performs self-service by automatically detecting skin brightness changes and adjusting the makeup image brightness without user intervention. The brightness adjustment process is handled autonomously by the system, reducing the need for complex user operations while maintaining high matching accuracy.

AI summary
An image synthesis device includes imaging unit (110) that photographs video, displayer (150) that displays the photographed video, and makeup image superimposing unit (140) that changes brightness of a makeup image superimposed with a face of the video on a pixel basis and superimposes the makeup image of which the brightness is changed on the face of the video, every time skin brightness of the face included in the video changes. Even if the brightness that illuminates the face changes, it is possible to synthesize the makeup image with an image familiar to the skin in real time.
