Abstract: A parallax image in which a parallax is associated with each pixel is acquired from an image captured by a stereo camera. The parallax is voted to a two-dimensional matrix. A line is extracted from a coordinate system in which an X-axis indicates the parallax and a Y-axis indicates the pixel in the vertical direction. In the case where a first line and a second line are detected, an X-coordinate of the start point coordinates of the second line is larger than an X-coordinate of end point coordinates of the first line, and the difference between the slope of the first line and the slope of the second line falls within a permissible range, a determination section determines that a low position is present at a position farther from the movable body than a position in real space corresponding to a Y-coordinate of start point coordinates.

Abstract: Based on viewing tracking data, a viewer's view direction to a three-dimensional (3D) scene depicted by a first video image is determined. The first video image has been streamed in a video stream to the streaming client device before the first time point and rendered with the streaming client device to the viewer at the first time point. Based on the viewer's view direction, a target view portion is identified in a second video image to be streamed in the video stream to the streaming client device to be rendered at a second time point subsequent to the first time point. The target view portion is encoded into the video stream with a higher target spatiotemporal resolution than that used to encode remaining non-target view portions in the second video image.
