Screen Change Detection for Remote Conference Documentation

The patent introduces a detecting section as an intermediary component that mediates between the image processing function and the communication function. This detecting section specifically monitors for significant screen changes (such as page switches or topic changes) and triggers documentation only when such changes are detected, rather than continuously transmitting all image differences. This intermediary layer resolves the contradiction by filtering out minor variations while capturing important information.

The patent implements preliminary action by having the detecting section continuously monitor screen changes in real-time during the remote conference. The detecting section is prepared in advance to identify significant changes, and when detected, it triggers the documentation function to capture the current screen state. This preliminary detection mechanism ensures that important screen changes are not missed while avoiding unnecessary documentation of minor variations.

The patent applies the extraction principle by isolating and extracting only the significant screen changes from the continuous stream of image data. The detecting section is designed to identify specific types of changes (page switches, topic changes) and extract only those moments for documentation. This extraction approach eliminates the need to process and review all screen changes, significantly reducing review time while preserving all important information.

The patent implements partial action by documenting only a subset of screen changes - specifically those deemed significant by the detecting section. Rather than capturing every single screen variation, the system selectively documents partial changes that meet certain criteria (such as substantial content changes). This partial documentation approach maintains information quality while dramatically reducing the volume of data requiring review.

The patent applies local quality by making the documentation function selective rather than uniform. The detecting section evaluates each screen change locally and determines whether it meets the threshold for documentation based on its significance. This local quality assessment ensures that documents are generated only where necessary (at significant change points) rather than uniformly for all screens, reducing document volume while maintaining information completeness.

The patent implements partial action in documentation by capturing only a partial set of screen snapshots - specifically those representing significant changes. The system deliberately does not document every screen state,而是 selectively documents only those moments where important information transitions occur. This partial documentation strategy maintains adequate records while significantly reducing the quantity of documents generated and stored.
