Abstract

A method and a system for a mobile terminal camera, to automatically adapt to scenarios, may include collecting motion data of a mobile terminal, within a predetermined period of time, via a sensor, acquiring a number of times when a maximum value of the motion data exceeds a predetermined value, obtaining a current motion scenario through analysis of the motion data according to the number of times the motion data exceeds the predetermined value, and automatically adjusting camera operation parameters according to the current motion scenario. Thereby, the present invention may make it unnecessary for a user to conduct frequent operations, so the user can conveniently and rapidly take pictures or videos in agreement with a current environment.
