US Patent 7720364 Triggering data capture based on pointing direction

Methods and apparatus for triggering directional data capture based on pointing direction are described. In an embodiment, the data captured is an image and a camera is described which includes a sensor for detecting the direction in which the image sensor of the camera is pointing. When the sensed pointing direction is one in which a worthwhile image is likely to be taken, the camera is triggered to capture a new image. The determination of when to capture a new image uses a metric based on the sensed direction and one or more specified trigger conditions.
