METHOD AND APPARATUS FOR CHOOSING A DESIRED FIELD OF VIEW FROM A WIDE-ANGLE IMAGE OR VIDEO

摘要

A wide-angle camera will collect wide-angle images. A portion of the wide-angle image (desired field of view) will be selected based on accelerometer readings. More particularly, to keep the desired field of view of a camera in an appropriate position, a correction is made to the tilt and roll of the desired field of view by using motion sensors to determine the horizon based on measuring the direction of gravity. A correction is also made to the yaw of the desired field of view using motion sensors to determine a forward facing position when the user is in motion. Because the desired field of view is corrected for variations resulting from user activity, any image collected from the camera is more likely to be pointed at a desired position.
