Freeze-Frame Video Transition With Visual Continuity

Solution Overview

Problem

Transitioning from a freeze frame video to a live video feed in video communication sessions can cause visual disruptions due to changes in the background or foreground, making the change noticeable to other participants and causing distractions.

Innovation Solution

A communication device and method that minimizes visual disruptions by detecting changes in the live video feed during the transition from a freeze frame video to a live video, modifying the live video to retain consistent visual characteristics with the freeze frame video, and presenting a modified live video to the communication session.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a freeze frame video is presented during a video call to temporarily turn off the live video feed, then the participant can avoid advertising that they have moved away or are distracted, but transitioning back to live video creates visual disruptions and noticeable changes

Engineering Contradiction:

Improvemaintaining consistent video appearanceVSAvoidvisual disruptions during transition

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The system performs preliminary actions by detecting changes in the live video feed before the transition occurs. It analyzes the captured video feed to identify differences between the freeze frame and current live video, preparing visual continuity measures in advance to prevent noticeable disruptions when switching back to live video.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system applies local quality by selectively modifying specific regions of the video feed. It identifies areas where changes occur (such as background or foreground elements) and applies targeted adjustments to those local regions while preserving other areas, ensuring smooth transition without affecting the entire video frame uniformly.

Inventive Principle:

Principle #3Local quality

2Productivity

If the live video feed is transmitted immediately after freeze frame, then the transition is quick and simple, but noticeable changes in background or foreground cause visual distractions

Engineering Contradiction:

Improvetransition speedVSAvoidvisual distractions

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

The system performs change detection and analysis in advance before the actual transition occurs. By preliminarily examining the video feed for changes and preparing appropriate modifications, the system enables rapid transition without causing visual distractions, resolving the conflict between speed and quality.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system implements feedback by continuously monitoring the video feed for changes and using this information to adjust the transition process. The detected changes feed back into the transition mechanism, which then applies appropriate modifications to ensure smooth visual continuity, allowing quick transitions without distractions.

Inventive Principle:

Principle #23Feedback

3Stability of the object's composition

If visual changes in the live video are detected and modified, then transition smoothness is improved, but additional processing increases device complexity

Engineering Contradiction:

Improvevideo visual consistencyVSAvoidvideo processing complexity

Core Design Contradiction:

Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The system performs change detection and analysis in advance before the actual transition occurs. By preliminarily examining the video feed for changes and preparing appropriate modifications, the system enables rapid transition without causing visual distractions, resolving the conflict between speed and quality.

AI summary

A communication device, a method, and a computer program product modifies visual characteristics of live videos to enable non-disruptive transition from presenting a freeze frame video to a video communication session. While presenting the freeze frame video, the device captures live video including the participant and current background. The device detects a change in at least one visual characteristic of the live video that can present a visual distraction to other participants of the video communication session while transitioning from presenting the freeze frame video to the video communication session. In response to detecting the change: the device modifies aspects of the live video to provide a modified live video that retains the at least one visual characteristic consistent with the freeze frame video. The device presents the modified live video to the video communication session on transition from presenting the freeze frame video to presenting live video.
