Layer Mirroring Interface for Selective Screen Sharing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current electronic devices do not support selective display of specific application interfaces during screen sharing or live broadcasting, which can compromise user privacy and lead to inefficient image transmission.
Innovation Solution
An image display method that generates a layer mirroring instruction upon user selection, creating a layer transmission interface to send selected layer data to a multimedia module for rendering and merging into video data, allowing only the chosen application window to be projected while adjusting display parameters for enhanced image quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If all display images on the screen are transmitted during screen sharing or live broadcasting, then the communication object can see all application interfaces, but user privacy is compromised and transmission efficiency is reduced
Solution Approach 1:
The display screen is segmented into multiple independent layers, each representing a different application interface. The system allows selective transmission of specific layers rather than the entire screen, enabling privacy protection for certain applications while maintaining transmission efficiency by only sending necessary layer data to the communication object
Solution Approach 2:
The system extracts and isolates specific layer data from the complete display output. By creating a layer transmission interface, it separates the selected application layer from other layers, transmitting only the extracted relevant data to the communication object, thereby protecting privacy while optimizing transmission efficiency
2Loss of information
If layer-based selective display is implemented, then user privacy is protected and transmission efficiency is improved, but device complexity increases
Solution Approach 1:
The layer transmission interface is designed as a universal mechanism that works across different applications and screen sharing scenarios. By creating a multi-functional interface that can handle various layer types and transmission requirements, the system achieves privacy protection without proportionally increasing complexity, as the same interface structure serves multiple purposes

AI summary
The present disclosure relates to an image display method and device, an electronic device, and a storage medium. The method includes: when a layer mirroring operation for layer-based mirroring of a display image is detected, a layer mirroring instruction including identification information of a layer to be mirrored is generated; responsive to the layer mirroring instruction, a layer transmission interface is created for the layer to be mirrored; the layer mirroring instruction and information of the layer transmission interface are sent to a graphics composition thread; the graphics composition thread is triggered to send layer data of the layer to be mirrored to a multimedia module based on the identification information of the layer to be mirrored through the layer transmission interface, and the multimedia module renders and merges the layer data of the layer to be mirrored into image video data; and the image video data is output.
