Transparent Display Front Camera Video Communication Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile terminal users face difficulties in aligning their image with the front camera during video communication, as the camera is offset from the display, leading to an unnatural appearance and reduced engagement due to the need to constantly adjust their gaze between the camera and the screen.
Innovation Solution
A system comprising a transparent display and a front camera positioned behind it, synchronized with the screen output, allowing users to monitor their captured image and adjust their position naturally, while also centering the other party's image to create a face-to-face communication experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the front camera is positioned offset from the display to enable video communication function, then the video communication function is achieved, but the user's glance is directed away from the camera causing unnatural appearance in captured images
Solution Approach 1:
A transparent display is introduced as an intermediary between the front camera and the user. The transparent display allows the user to see through it while viewing their captured image, enabling them to naturally look at the camera while monitoring their appearance in real-time. This mediator resolves the conflict between camera positioning and natural gaze direction.
2Ease of operation
If the front camera is positioned away from the user's line of sight to allow display positioning, then the display layout flexibility is improved, but the user cannot monitor their captured image naturally
Solution Approach 1:
The transparent display utilizes optical property changes (transparency) to enable dual functionality. The display can show images while remaining transparent, allowing users to see through it to the camera while monitoring their captured image, thus maintaining self-monitoring capability without compromising display layout flexibility.
3Adaptability or versatility
If the front camera is positioned at a distance from the display, then the structural design flexibility is improved, but the user appears to look away in captured images during video communication
Solution Approach 1:
The transparent display serves as a mediator that bridges the distance between the camera and the user's line of sight. It allows the camera to be positioned at a distance for structural flexibility while enabling the user to look naturally at the camera by displaying their captured image on the transparent surface they are already looking at.
4Measurement precision
If the user constantly adjusts their gaze between the camera and the screen to monitor their image, then the image monitoring accuracy is improved, but the ease of operation deteriorates
Solution Approach 1:
The transparent display merges the camera viewing path with the display viewing path. The user views their captured image on the transparent display while simultaneously looking at the camera, combining both functions into a single line of sight. This eliminates the need to constantly shift gaze between camera and screen, maintaining monitoring accuracy while improving ease of operation.

AI summary
A method and an apparatus for taking an image and conducting video communication are provided. The image-taking and video communication apparatus includes a transparent display, a front camera, and a controller. The front camera is positioned behind the transparent display and captures an image of an object in front of the transparent display through the transparent display. The controller synchronizes an image capture period of the front camera with a screen output period of the transparent display so that image capturing of the front camera alternates with screen output of the transparent display.
