Virtual Background Alignment During Video Focus Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In video conferences, focal adjustments cause the front view object to separate from the virtual background, leading to an unnatural display and diminished user experience.
Innovation Solution
A method and device that analyze movement parameters of the front view object relative to historical frames to adjust the virtual background image synchronously, ensuring integration with the front view object, using movement parameters to scale, translate, and adjust brightness and blurring of the virtual background image.

Engineering Contradiction Analysis
1Measurement precision
If focal adjustment is performed on the camera, then the focus accuracy is improved, but the front view object separates from the virtual background, causing unnatural display
Solution Approach 1:
The patent applies dynamics by making the virtual background adjustable according to the movement parameters of the front view object. When the object moves or changes position during focal adjustment, the virtual background is dynamically modified (through translation, scaling, or other transformations) to maintain proper alignment and integration with the object, preventing separation and ensuring natural display appearance
Solution Approach 2:
The patent changes parameters of the virtual background image based on movement parameters extracted from the front view object. By calculating movement parameters (such as position changes, scale changes, or transformation matrices) from the object's motion, the system adjusts the virtual background's parameters (position, size, orientation) to match the object's movements, maintaining consistent integration throughout the video stream

AI summary
A video virtual background image processing method includes receiving a trigger instruction, obtaining a first video frame and a historical video frame neighboring to or apart at a certain number of frames from the first video frame, obtaining a movement parameter of a front view object in the first video frame relative to the historical video frame, and performing adjustment on a virtual background image displayed in a video interface according to the movement parameter.
