Web Conference Screen Layout for Selected Participant Extraction

The patent extracts specific participant images from the complete set of participant images based on predetermined conditions (such as speaking status, role, or selection criteria). Only the extracted relevant participant images are displayed on the screen alongside the material, while other participant images are omitted. This resolves the contradiction by selectively taking out only the necessary information rather than displaying everything, thus maintaining screen organization while preserving important participant information visibility.

The patent creates simplified copies of participant images (such as thumbnails or reduced-resolution versions) for display purposes. These copied images are sufficient for identification and visibility enhancement but require less processing power and system resources than full-resolution images. This approach enhances specific participant visibility while minimizing the increase in system complexity by using lightweight image copies rather than processing complete high-resolution images.

The patent implements periodic updates of participant images at predetermined time intervals rather than continuous real-time updates. The system captures participant images at specific intervals (e.g., every few seconds or minutes) and updates the display accordingly. This periodic approach maintains reasonably accurate real-time information while significantly reducing the processing load and time consumption compared to continuous updates, thus resolving the contradiction between information reliability and time loss.
