An image processing method includes: receiving a plurality of images, the images being captured under different view points; and performing image alignment for the plurality of images by warping the plurality of images, where the plurality of images are warped according to a set of parameters, and the set of parameters are obtained by finding a solution constrained to predetermined ranges of physical camera parameters. In particular, the step of performing the image alignment further includes: automatically performing the image alignment to reproduce a three-dimensional (3D) visual effect, where the plurality of images is captured by utilizing a camera module, and the camera module is not calibrated with regard to the view points. For example, the 3D visual effect can be a multi-angle view (MAV) visual effect. In another example, the 3D visual effect can be a 3D panorama visual effect. An associated apparatus is also provided.
