Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional client devices require manual user input to configure and adjust video capture parameters, limiting users' ability to perform other tasks during video messaging sessions and failing to adapt to changing conditions without continuous user intervention.
Innovation Solution
Incorporating a controller that applies machine learning models to video data to modify capture settings and parameters, such as focal point and magnification, based on previously captured data, while enforcing privacy settings and automatically adjusting to prioritize users within the frame.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual user input is required to configure video capture parameters, then user control over video data is improved, but user convenience and ability to perform other tasks deteriorates
Solution Approach 1:
The system automatically analyzes video data from the environment and self-adjusts capture parameters without requiring continuous user input. The controller monitors the local area, identifies users, and autonomously modifies focal point, magnification, and framing based on detected conditions, allowing the device to serve itself rather than requiring manual user configuration for each adjustment.
Solution Approach 2:
The system continuously monitors video data and uses this feedback to automatically adjust capture parameters. By analyzing previously captured video data and current environmental conditions, the controller dynamically modifies focal point, magnification, and framing to maintain optimal capture of users in the scene, creating a closed-loop system that adapts without manual intervention.
2Manufacturing precision
If manual user input is required to adjust video capture, then capture precision is improved, but adaptability to changing conditions deteriorates
Solution Approach 1:
The system transitions from static manual configuration to dynamic automatic adjustment. The controller continuously monitors video data and environmental conditions, dynamically modifying capture parameters in real-time to adapt to changing scenes, user positions, and lighting conditions while maintaining precise focus and framing through algorithmic control.
Solution Approach 2:
The system autonomously detects changes in the local area and self-adjusts capture parameters without requiring user awareness or intervention. The controller monitors video data, identifies when users enter or leave the frame, and automatically modifies focal point and magnification to maintain optimal capture, enabling the device to adapt to changing conditions independently.
3Ease of operation
If the system automatically modifies video capture based on previously captured data, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The system replaces manual mechanical adjustment mechanisms with automated electronic processing. Instead of requiring physical user interaction to adjust focus and framing, the controller uses image processing algorithms and electronic control signals to automatically modify capture parameters, substituting computational complexity for mechanical user interaction.
Solution Approach 2:
The system performs preliminary analysis of video data to pre-determine optimal capture parameters before actual capture adjustments are needed. By continuously analyzing previously captured data and predicting required adjustments, the controller prepares modification commands in advance, reducing the computational burden during real-time capture and smoothing the automation process.

AI summary
Various client devices include displays and one or more image capture devices configured to capture video data. Different users of an online system may authorize client devices to exchange information captured by their respective image capture devices. Additionally, a client device modifies captured video data based on users identified in the video data. For example, the client device changes parameters of the image capture device to more prominently display a user identified in the video data and may further change parameters of the image capture device based on gestures or movement of the user identified in the video data. The client device may apply multiple models to captured video data to modify the captured video data or subsequent capturing of video data by the image capture device.
