The mobile terminal of claim 6, wherein the smart terminal microprocessor is further configured to compare each of the plurality of motion pictures with a previous one of the plurality of motion pictures; recording the displacement vector of the target moving object obtained after each comparison; the displacement vector includes a displacement magnitude and a displacement direction.
8. The mobile terminal of claim 7, wherein the smart terminal microprocessor is further configured to stop comparing the plurality of moving images when a shutter is pressed; obtaining a displacement vector after the last comparison; calculating a dynamic vector of the motion image according to the preset time interval and the displacement vector after the last comparison; the dynamic vector comprises a moving speed and a moving direction; sending the dynamic vector to a motor control chip through an I2C interface;
and the motor control chip is also used for driving and controlling the motor to drive the lens to translate at the same speed as the moving speed in the direction opposite to the moving direction within the exposure time according to the dynamic vector.
