The image stabilization method for the panoramic video is applicable to an electronic apparatus including a processor. In the method, a plurality of image frames of a panoramic video is captured, and each image frame is transformed into a plurality of projection frames on a plurality of faces of a cubemap.

The variations of triaxial displacements and attitude angles are smoothed and recorded as movement information. While playing the panoramic video, the panoramic video is corrected by the movement information and played. Thus, it is possible to reduce the amount of calculation required for the stabilization calculations on the captured video.
