Video Call Terminal Selective Image Capture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current video call technologies lack methods to enhance user convenience by efficiently capturing and sharing video call information, requiring significant storage space and lacking intuitive methods for managing and providing related information.
Innovation Solution
A method and apparatus for a video call terminal that captures and displays images based on preset conditions, such as time elapsed or user expressions, allowing users to easily manage and share video call information after the call, using a transceiver, controller, and display unit to receive, process, and store video call data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If video call information is stored for later review and sharing, then user convenience is improved, but storage space requirements increase significantly
Solution Approach 1:
The patent extracts only the essential and meaningful moments from continuous video call data by detecting specific capture conditions (user expressions, time intervals, call termination). This selective extraction of key frames rather than storing entire video streams significantly reduces storage space while maintaining user convenience for reviewing important call moments.
Solution Approach 2:
The system performs partial action by capturing only certain portions of the video call based on predefined conditions rather than storing the complete video stream. This partial capture approach (capturing key moments instead of everything) reduces storage requirements while still providing sufficient information for user review and sharing.
2Loss of information
If all video call information is captured and stored, then complete information is available for review, but device complexity and storage requirements increase
Solution Approach 1:
The system performs preliminary action by pre-defining capture conditions (time intervals, user expressions, call termination events) before the video call occurs. This preliminary setup allows the system to automatically capture relevant information without requiring complex real-time analysis during the call, reducing device complexity while maintaining information completeness for key moments.
Solution Approach 2:
The system serves itself by automatically detecting capture conditions and selecting frames to store without requiring continuous user intervention or complex manual processing. The terminal autonomously determines when to capture based on predefined conditions, simplifying the system while ensuring important information is retained.
3Loss of information
If video call videos are stored for sharing, then information availability is improved, but storage space and processing requirements increase
Solution Approach 1:
The patent extracts only essential key frames from video call data based on predefined capture conditions rather than processing and storing complete video streams. This extraction approach maintains information availability for sharing while significantly reducing the processing energy required to handle, store, and transmit video data.

AI summary
A method for a video call in a terminal for performing the video call includes receiving at least one of a video of another party user side or a video of a terminal user side; determining whether a preset capture condition is satisfied based on the received video; capturing an image satisfying the preset capture condition; determining whether the video call is terminated; and displaying at least one of the captured images on a display unit when the video call is terminated.
