AUTOMATICALLY CAPTURING FOCUSED IMAGES OBTAINED THROUGH UNGUIDED MANUAL FOCUS ADJUSTMENT

摘要

In an image capture period, light from a scene is received through an optical system free of automatic focusing components. A sequence of focal values is produced from image data produced during the image capture period. One or more target focus criteria are determined from one or more of the focal values produced during a calibration portion of the image capture period. An image of the scene is automatically captured in response to a determination that one or more of the focal values produced after the calibration portion of the image capture period satisfies the target focus criteria.
