A cut-out module (102) in the video conferencing server (100) generates a foreground mask (122) for a video frame (121) received from a conferencing client (101). A camera shake detector (103) determines a displacement vector (123) for a subset of features in the video frame (121). The displacement vector (123) represents a two-dimensional motion of the subset of features between a background mask and a previous background mask for a previous video frame received from the same conferencing client (101). A camera shake correcting module (102, 104) applies a displacement opposite to the displacement vector (123) to the foreground mask (122) before use thereof in the immersive video streams (124, 125) for conferencing clients (101), and a signalling unit (104) generates a shake indication (311, 312) into the immersive video stream (124) delivered to the conferencing client (101) whose camera is shaking."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Videoconferencing server with camera shake detection","description":"A video conferencing server (100) receives and combines video streams captured by cameras of plural video clients (101) and generates immersive video streams (124, 125) for delivery to and play-out by","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9762856","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
