Claim 4:
5. The method of claim 3, wherein determining whether the difference between the reference shooting trajectory and the current shooting trajectory meets the preset condition further includes:
taking a sampling position corresponding to the current image frame as the current sampling position, and taking a sampling position corresponding to the image frame obtained in the previous sampling as a historical sampling position;
determining a current reference position from the reference shooting trajectory based on the current sampling position, and determining the historical reference position from the reference shooting trajectory based on the historical sampling position;
determining a first moving direction based on the current sampling position and the historical sampling position, and determining a second moving direction based on the current reference position and the historical reference position; and
determining whether the difference between the reference shooting trajectory and the current shooting trajectory meets the preset condition based on the first moving direction and the second moving direction.
