Claim 0:
1. A projection image anti jitter method, comprising:
capturing jitter data of a projection lens;
acquiring jitter characteristic information by calculation based on the jitter data;
acquiring offset data of the projection lens based on the jitter characteristic information; and
adjusting the projection lens based on the offset data;
wherein capturing the jitter data of the projection lens comprises:
capturing an acceleration and an angular velocity of jitter of the projection lens using a six-axis sensor;
wherein acquiring the jitter characteristic information by calculation based on the jitter data comprises:
acquiring a variation parameter of an Euler angle of the projection lens by calculation based on the acceleration and the angular velocity; wherein
the variation parameter of the Euler angle comprises a yaw angle, a pitch angle, and a roll angle that are variable with time.
