Dynamic Video Image Positioning for Unobstructed Presentation Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In video conferencing, the fixed position and size of the image area can block presentation content, making it difficult for the audience to read easily.
Innovation Solution
An image processing method and apparatus that identifies suitable background areas on a shared screen, determines if their size conforms to a character representative image, and presents the image in a background area matching its size, avoiding overlap with presentation content.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the image area is displayed with fixed position and size, then the speaker's expression and gestures are clearly visible, but the presentation content is blocked and difficult to read
Solution Approach 1:
The patent implements dynamic positioning of the image area by detecting background areas on the shared screen and automatically adjusting the image position and size to fit within suitable background regions. This transforms the static fixed-position display into a dynamic adaptive display that responds to the actual screen content, resolving the contradiction between maintaining speaker visibility and preserving presentation content readability.
Solution Approach 2:
The patent applies local quality by identifying specific background areas on the screen and placing the image only in those regions that are suitable for display. This ensures that the image is positioned in locations that do not interfere with important presentation content, while still maintaining clear visibility of the speaker's expression and gestures.
2Stability of the object's composition
If the image position and size are fixed, then the display layout is simple and stable, but the image may cover important presentation content
Solution Approach 1:
The system maintains layout stability through automated dynamic adjustment. By continuously monitoring the shared screen for suitable background areas and automatically repositioning the image, the system provides a stable user experience without manual intervention while avoiding content obstruction through intelligent positioning.
Solution Approach 2:
The system performs self-service by automatically detecting suitable background areas and adjusting the image position and size without requiring manual user input. This eliminates the need for users to manually position the image to avoid content, while the system autonomously resolves the conflict between stable layout and content visibility.
3Measurement precision
If the image area is enlarged to show more details, then the speaker's features are more visible, but it blocks more presentation content
Solution Approach 1:
The patent applies local quality by identifying specific background areas on the screen and placing the image only in those regions that are suitable for display. This ensures that the image is positioned in locations that do not interfere with important presentation content, while still maintaining clear visibility of the speaker's expression and gestures.
Solution Approach 2:
The system dynamically adjusts the image size based on the detected background area size and position. By automatically scaling the image to fit within suitable background regions, the system maximizes the visible details of the speaker while minimizing obstruction of presentation content, resolving the contradiction between detail visibility and content coverage.

AI summary
An image processing method and an image processing apparatus for video conferencing are provided. In the method, one or more background areas in a shared screen are identified. Whether a size of the one or more background areas conforms to a size of a character representative image is determined. The character representative image is presented in a background area conforming to the size of the character representative image. Therefore, the complete briefing content can be seen.
