Camera View Manipulation for Video Conference Clarity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Participants in video conferences face challenges in articulating their intentions due to limitations in audio and video signals captured by microphones and cameras, which do not adequately convey the desired information.
Innovation Solution
The technology enables participants to manipulate camera views during a video conference by enlarging, focusing, or increasing the resolution of specific image regions, allowing users to zoom, re-focus, or apply super resolution on either their local or peer's camera images using manipulation instructions and corresponding stored commands.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If standard audio/video signals are used for communication, then the system remains simple and compatible, but the ability to articulate and convey detailed information is insufficient
Solution Approach 1:
The patent segments the video feed into multiple regions of interest (ROIs), allowing specific areas to be highlighted and manipulated independently. This enables detailed information about particular objects or scenes to be conveyed without requiring a complete change of the overall video system, thus reducing the complexity-information tradeoff.
Solution Approach 2:
The patent adds a spatial dimension to information conveyance by enabling zoom, pan, and focus operations on specific regions. Instead of relying solely on audio description or full-scene video, the system manipulates the spatial presentation of video content to highlight important details, thereby increasing information conveyance without proportionally increasing system complexity.
2Measurement precision
If the entire video scene is transmitted at high resolution, then visual clarity is maximized, but bandwidth consumption and processing requirements increase significantly
Solution Approach 1:
The patent applies different quality levels to different regions of the video feed. Regions of interest are transmitted at high resolution while other areas use lower resolution, maintaining visual clarity where needed while reducing overall bandwidth consumption through selective quality adjustment.
Solution Approach 2:
The patent extracts and prioritizes transmission of specific regions of interest from the full video scene. By separating and independently managing the transmission quality of important regions versus the rest of the scene, the system achieves high visual clarity for critical content without transmitting the entire scene at maximum quality, thus optimizing bandwidth usage.
3Ease of operation
If users can manipulate camera views in real-time during video conferences, then communication effectiveness improves, but system complexity and control requirements increase
Solution Approach 1:
The patent implements self-service mechanisms where the system automatically identifies and highlights regions of interest based on content analysis, reducing the need for complex manual controls. Users can initiate simple gestures or commands, and the system handles the complex manipulation of camera views automatically, improving communication effectiveness while keeping the control interface simple.
Solution Approach 2:
The patent incorporates feedback loops where the system monitors video content, automatically identifies important regions, and adjusts camera view manipulation accordingly. This automated feedback mechanism reduces the complexity of manual control systems while maintaining effective communication by dynamically adapting to the conversation context.

AI summary
A method and system for enabling a first device to change a viewed image of at least one of the first device and a second device, during a video conference, are disclosed. The method includes: receiving a manipulation instruction, at a first device, for a selected target image, wherein the selected target image includes a portion of images displayed on a display of the first device during a video conference with a second device; comparing the manipulation instruction to an instruction store; and changing, on at least one of the first device and the second device, a view of the selected target image according to the manipulation instruction to achieve a manipulated selected target image.
