Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current digital communication technologies do not allow for the capture of high-resolution images during real-time communications, leading to limitations in detail capture and potential communication breakdowns due to bandwidth constraints.
Innovation Solution
Implementing a webcam system that can switch between standard and high-resolution modes, allowing for brief high-resolution captures with increased resources and marking the bitstream to indicate resolution changes, enabling efficient transmission and storage of high-resolution images without disrupting the communication session.

Engineering Contradiction Analysis
1Measurement precision
If high-resolution image capture is implemented during real-time communication, then image quality and detail are improved, but bandwidth consumption increases and may cause communication breakdown
Solution Approach 1:
The system dynamically adjusts the resolution of image capture based on communication conditions. During normal real-time communication, the system operates at standard resolution to maintain session stability. When a user triggers a photo capture event, the system temporarily switches to high-resolution mode, captures the image, then immediately returns to standard resolution, thereby achieving high-quality capture without sustained bandwidth overhead that would compromise communication reliability.
Solution Approach 2:
The system employs periodic high-resolution capture at specific intervals or triggered events rather than continuous high-resolution streaming. The photo capture mechanism activates temporarily at predetermined moments (e.g., when a participant requests to share their screen or show something), allowing high-resolution images to be captured and transmitted without requiring continuous high-bandwidth allocation, thus preventing communication breakdown while achieving detailed image capture.
2Measurement precision
If high-resolution capture is performed, then image detail is improved, but resource consumption increases
Solution Approach 1:
The system dynamically adjusts resource allocation for image capture based on operational needs. During normal real-time communication, the system uses standard resolution settings that consume minimal resources. Upon triggering a photo capture event, the system temporarily allocates additional resources to enable high-resolution capture, then immediately releases those resources back to the communication session, thereby achieving high-detail images without sustained resource consumption that would degrade overall system performance.
3Productivity
If standard resolution is used during real-time communication, then bandwidth efficiency is improved, but image detail is insufficient
Solution Approach 1:
The system uses standard resolution for continuous real-time communication to maximize bandwidth efficiency, then periodically switches to high-resolution mode at specific triggered moments (e.g., when a participant wants to share a photo or document). This periodic high-resolution capture provides detailed images when needed without requiring continuous high-bandwidth allocation, thereby maintaining overall bandwidth efficiency while achieving sufficient image detail at critical moments.
Solution Approach 2:
The system dynamically switches between standard and high-resolution modes based on communication context. During normal interaction, standard resolution maintains bandwidth efficiency. When a photo capture event is triggered (e.g., participant requests to show something), the system dynamically transitions to high-resolution mode to provide necessary image detail, then returns to standard resolution, thereby achieving optimal balance between bandwidth efficiency and image detail based on real-time needs.

AI summary
During remote communication session, there can be situations where information needs to be sent at a high resolution. Sending information at a high resolution allows for the capture of detail that can be lost without the use of a high resolution. A web camera can obtain information in both a higher resolution and standard resolution. A sending component can send this information encoded with markers that allow a receiving component to process and display the information.
