An optical element driving mechanism having an optical axis includes a fixed portion, a movable portion, and a driving assembly. The movable portion is connected to the fixed portion. The driving assembly drives the movable portion to move in a direction that is parallel to the optical axis relative to the fixed portion, when viewed in the direction that is parallel to the optical axis, the optical element driving mechanism is a rectangular structure with a first side, a second side, a third side, and a fourth side, the first side and the third side are opposite, and the first side is adjacent to the second side and the fourth side.

The present invention provides a method for non-linearly stretching a cropped image, including: obtaining an FOV difference table of a panoramic lens; calculating a polynomial of an approximated curve represented by the values of the FOV difference table; shooting a circular wide-angle image using the panoramic lens; cropping the circular wide-angle image to preserve the remaining circular wide-angle image under a specific viewing angle; under the specific viewing angle, resampling a plurality of points by the polynomial to obtain the corresponding spacing distance of the points; and while maintaining the ratio of the spacing distance between the plurality of points, stretching the remaining circular wide-angle image to the size of the original circular wide-angle image.
