Video Call Exposure Control for Privacy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Video call services lack user control over image exposure, potentially compromising privacy as users cannot adjust the visibility of their image in real-time during calls.
Innovation Solution
A method and system that allow users to control the exposure area of their image during video calls by establishing a video call session, displaying an exposure control area, receiving user input, and transmitting signals to adjust the exposure area in real-time, enabling users to selectively show or hide parts of their image.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the entire image is exposed during video call, then the communication quality and face-to-face interaction are improved, but the user's privacy is compromised
Solution Approach 1:
The image is divided into multiple regions with different exposure levels. The exposure area is segmented from the non-exposure area, allowing the user to control which parts of the image are visible to the other party. This segmentation enables selective disclosure of information while maintaining overall communication quality.
Solution Approach 2:
The exposure area is made dynamically adjustable during the video call. The user can change the size and position of the exposure area in real-time based on their privacy needs, transforming a static full-exposure system into a dynamic, adaptable one that balances communication quality and privacy protection.
2Object-affected harmful factors
If the exposure area is reduced to protect privacy, then privacy is improved, but the communication quality and face-to-face interaction deteriorate
Solution Approach 1:
Instead of completely exposing or completely hiding the image, the system applies partial exposure - showing only the necessary portion of the image required for communication while hiding the rest. This partial action approach provides sufficient communication quality while achieving privacy protection for sensitive areas.
3Device complexity
If no exposure control is provided, then the device complexity is reduced, but the user's ability to control privacy is limited
Solution Approach 1:
The exposure control interface acts as an intermediary between the user and the image transmission system. By providing a simple graphical interface with drag-and-drop functionality, it mediates the complex process of privacy control, allowing users to easily adjust exposure areas without dealing with complex technical parameters.

AI summary
There is provided an application stored in a computer-readable storage medium and enabling a first terminal to perform a method of providing a video call service, the method includes: establishing a video call session between the first terminal and a second terminal; displaying an exposure control area for controlling an exposure area of an image of a first user displayed on the second terminal; receiving an input of the first user for controlling the exposure control area; and transmitting a signal for controlling the exposure area to the second terminal in response to the input of the first user.
