Digital image processing

摘要

A method of enhancing pictures recorded by a digital imaging device, including, activating the imaging device to record a burst of multiple consecutive digital pictures, recording the pictures of the burst, selecting one of the digital pictures of the burst to serve as a base picture, estimating alignment of each picture to compensate for motion relative to the base picture, enhancing the base picture by combining with details from the other recorded pictures of the burst while compensating for the motion, providing the enhanced picture as output.

1. A method of enhancing pictures recorded by a digital imaging device, comprising:
activating the imaging device to record a burst of multiple consecutive digital pictures of captured optical images; reading global positioning sensors that provide global alignment information of the imaging device; reading status of sensors and setting parameters for recording the burst responsive to the readings of the sensors; recording the pictures of the burst with the global alignment information of the imaging device read from the global positioning sensors in synchronization with the captured optical images; determining for each of the pictures of the burst global motions due to movement of the imaging device as well as local motions due to movements of elements in captured scenes of the pictures; selecting one of the digital pictures of the burst to serve as a base picture; based on the positioning data obtained from the global positioning sensors and further based on the determined global motions and the determined local motions estimating alignment of each picture to compensate for motion relative to the base picture; enhancing the base picture by combining with details from other recorded pictures of the burst, referred to as auxiliary pictures, while compensating for the motion; providing the enhanced picture as output.
