阅读说明：本技术 沉浸式视频体验 (Immersive video experience ) 是由 W·李 V·杨 J·卢克 C·格雷尼尔 J·金 E·范 L·阿尔维斯 B·汉森 李晨 于 2020-02-24 设计创作，主要内容包括：公开了基于沉浸式视频体验的视频操作技术。确定与视频有关的参数。确定与视频显示器有关的第二参数。基于视频的高度和宽度计算最小尺度值以在椭圆内内接矩形。视频的高度和宽度定义了椭圆的边界,视频显示器的高度和宽度定义了矩形。使用低通滤波器对重力传感器输入进行预处理,然后再使用它来确定最小尺度值。使用视频嵌入和视口嵌入对视频进行预处理。可以修剪视频,可以缩放矩形。视频的矩形部分被渲染在视频显示器上,其中矩形部分在椭圆的边界之上或之内。(Video manipulation techniques based on immersive video experiences are disclosed. Parameters related to the video are determined. A second parameter associated with the video display is determined. A minimum scale value is calculated based on the height and width of the video to inscribe a rectangle within an ellipse. The height and width of the video defines the boundaries of the ellipse and the height and width of the video display defines the rectangle. The gravity sensor input is preprocessed using a low pass filter and then used to determine the minimum scale value. Video embedding and viewport embedding are used to pre-process the video. The video can be cropped and the rectangle can be zoomed. A rectangular portion of the video is rendered on the video display, where the rectangular portion is above or within the boundaries of the ellipse.)
