Abstract:
A device has a camera that is moveable by one or more actuators. During operation the camera moves. For example, the camera may move to follow a user as they move within the physical space. Mechanical limitations result in the camera movement exhibiting discontinuities, such as small jerks or steps from one orientation to another while panning. If the camera is acquiring video data while moving, the resulting video data may appear jittery and be unpleasant for a user to view. An offset is determined between an intended orientation of the camera at a specified time and an actual orientation of the camera at that time. A portion of raw image data acquired at the specified time is cropped using the offset to produce cropped image data that is free from jitter due to the movement discontinuities.
