Abstract

Embodiments of the present invention provide a method, an apparatus, and a mobile device for photographic processing. A spatial position parameter of a mobile device is collected by a gravity sensor in real time. According to the spatial position parameter of the mobile device, stability degrees of the mobile device at multiple reference moments before a current reference moment and a stability degree of the mobile device at the current reference moment are separately computed. Photographic processing is performed according to the stability degrees of the mobile device at the multiple reference moments before the current reference moment and the stability degree of the mobile device at the current reference moment.
