Multi-Video Compositing With Transparency-Controlled Screen Regions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video processing systems struggle to effectively synthesize and display multiple video feeds from different cameras in a single screen, often resulting in unclear boundaries between videos and a lack of user-configurable display sizes.
Innovation Solution
A video processing device and system that utilize a synthesis processing unit to generate a synthetic video signal by rendering one video transparent and overlaying it with another, allowing for user-controlled transparency and display size adjustments through stored transparency control data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple recorded videos are linked to be displayed in one screen, then the user can view multiple video feeds simultaneously, but the boundary between the recorded videos becomes unclear
Solution Approach 1:
The patent applies transparency control to change the visual properties of video regions. By controlling the transparency of the first video in a designated region, the system creates clear visual boundaries between multiple video feeds through transparency transitions, allowing users to distinguish between different video sources while maintaining simultaneous display capability
Solution Approach 2:
The patent implements region-specific transparency control where different parts of the screen have different transparency characteristics. The synthesis processing unit applies transparency control data to specific designated regions, creating local visual distinctions that clarify boundaries between videos without affecting the entire display
2Ease of operation
If the display size of each recorded video is made changeable, then the user can customize the view according to their needs, but the system complexity increases
Solution Approach 1:
The patent implements dynamic transparency control where the transparency of video regions can be changed based on stored control data. The synthesis processing unit reads transparency control data from storage and dynamically adjusts the transparency of the first video in designated regions, enabling flexible display size and shape changes without requiring complex real-time control mechanisms
Solution Approach 2:
The patent uses pre-stored transparency control data to define video display characteristics. The control data is stored in advance in a storage unit, containing information about designated regions and transparency aspects. This preliminary preparation simplifies the real-time processing by eliminating the need for complex on-the-fly calculations

AI summary
It is an object to provide a video processing device and a video processing system capable of synthesizing a plurality of videos and displaying the synthesized video on a single screen in a form according to a request of a user. The disclosure includes a synthesis processing unit that generates a synthetic video signal by rendering a first video included in a designated region in a screen transparent and synthesizing the first video and a second video in a manner in which the first video based on a first video signal is arranged in the screen and the second video based on a second video signal different from the first video signal is arranged in the screen, and a memory that stores transparency control data for specifying the designated region and indicating a transparency aspect of the first video in the designated region.
