パノラマカメラ及びバーチャルリアリティのヘッドセットに基づく選択的なコンテンツ処理のための方法及びシステム
Document Type and Number:
Japanese Patent JP7299451
Kind Code:
B2
Abstract:
Gaze positions of an operator wearing a virtual-reality headset displaying a video stream define preferred view regions of the display. Starting with a reference gaze position, and for each subsequent distinctly different gaze position, the virtual-reality headset sends control data, including three spatial coordinates and a time coordinate expressed as a cyclical video-frame index, to a view adaptor receiving the video stream. The view adaptor stores contents of a number of most recent video frames of the video stream in a circular content-buffer and control data of a number of most recent gaze positions in a circular control-buffer. A content filter within the view adaptor determines a preferred view region surrounding a gaze position according to control data held in the circular control-buffer and extracts a partial content of a respective frame held in the circular content-buffer according to the preferred view region.
