Digital Makeup Mirror Image Transformation for Mirror-Like Viewing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mirrors and camera-based systems fail to provide a reliable and accurate self-image for makeup sessions, leading to difficulties in remembering applied products and comparing different makeup options, as the image generated by a camera differs significantly from a mirror reflection, and users are accustomed to looking directly at a mirror.
Innovation Solution
A digital makeup mirror system that transforms the camera image to mimic a mirror reflection, centers the face on the screen, and applies virtual makeup, allowing recording and editing of makeup sessions for review, with features like facial feature identification, virtual product application, and adjustable lighting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a camera is positioned above the screen to capture the user's face, then the system can generate a video stream for display, but the image appears distorted and unnatural as the user does not look directly at the camera
Solution Approach 1:
The patent applies image transformation to flip and adjust the camera-captured image so that it appears as if the camera is positioned behind the screen, creating a mirror-like effect. This inversion of the normal camera view resolves the contradiction by making the image appear natural and direct to the user while maintaining the practical benefit of using a camera positioned above the screen.
2Adaptability or versatility
If a camera-based system is used to replace the conventional mirror, then the system can provide digital functionality, but the image generated is very different from a mirror reflection and not convincing
Solution Approach 1:
The patent creates a transformed copy of the camera image that mimics the optical properties of a mirror reflection. By applying image transformation algorithms, the system produces a copy of the user's appearance that closely resembles what they would see in a conventional mirror, thereby maintaining image authenticity while enabling digital functionality.
Solution Approach 2:
The patent transforms image parameters such as orientation, position, and perspective to convert the camera view into a mirror-like reflection. By changing these visual parameters, the system maintains the convincing realism of a mirror while incorporating digital capabilities.
3Ease of operation
If the user looks directly at the screen, then the user can see the displayed image, but the user seems to be looking away from the camera creating an unnatural appearance
Solution Approach 1:
The patent inverts the visual perspective by transforming the image to appear as if captured from behind the screen. This allows the user to look directly at the screen for convenience while the transformed image maintains the natural appearance of direct eye contact, resolving the contradiction between user convenience and image naturalness.

AI summary
A computer implemented method for emulating a mirror using camera video stream and a display screen to generate a digital mirror. The digital mirror is specifically configured for headshot applications, such as makeup and eyeglass tryout sessions. Provisions are made for correcting the appearance of the face on the screen. Specific implementations enable tracking the movement of the face or specific features of the face and applying virtual makeup or virtual glass or other accessories or other filters to the face. Also, recording sessions and auto-editing provides the user with easy accessibility to the tutorial session and the products used during the session. Products may be ordered from the user's mobile device at any time.
