Depth Camera Video Conference Participant Cropping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Participants in video conferences often manually adjust camera settings and manipulate their environment to capture themselves effectively, which is time-consuming and inefficient.
Innovation Solution
A system using depth cameras and sensors to automatically determine the distance and position of participants and background objects, creating a region of interest for optimal video capture and arranging video streams based on priority levels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If participants manually adjust camera settings and manipulate their environment, then video capture quality can be optimized, but the process becomes time-consuming and inefficient
Solution Approach 1:
The system uses depth cameras and sensors to automatically detect participant positions, determine regions of interest, and adjust video stream arrangements without requiring manual camera adjustment or environmental manipulation by participants
Solution Approach 2:
The patent replaces manual mechanical adjustments (camera positioning, physical object arrangement) with automated computer vision and depth sensing systems that automatically capture and arrange video streams based on detected participant positions
2Productivity
If automated systems are used to capture video streams, then efficiency is improved, but device complexity increases
Solution Approach 1:
The system uses multi-functional depth cameras and sensors that perform multiple tasks: detecting participant positions, determining background objects, identifying regions of interest, and guiding video stream arrangement, thereby reducing the need for separate dedicated devices for each function
Solution Approach 2:
The patent introduces a video conference application as an intermediary that processes data from depth cameras and sensors, automatically determines optimal video arrangements, and manages the complexity of coordinating multiple hardware components

AI summary
A method to present participants in a video conference including determining a participant distance and aligning a region of interest on the participant using one or more depth cameras, creating a cropped video stream of the participant by cropping the region of interest from a video stream of the participant, and arranging the cropped video stream of the participant with additional cropped video streams of additional participants for display in the video conference.
