1. An image processing method, comprising: obtaining all image characteristics contained in each of N captured images and determining at least one image characteristic from the all image characteristics; searching the N images for at least two images each containing the at least one image characteristic based on the at least one image characteristic; determining a reference image from the at least two images and obtaining image residue information characterizing an image difference parameter between the reference image and each of the at least two images; and applying data compression to the reference image and the image residue information to obtain a data compressed image data package having a data volume smaller than a data volume that would be obtained if the at least two images were compressed directly.
