Claim 0:
1. An image processing method for receiving M lens images and generating a projection image, comprising:
determining P optimal warping coefficients of P control regions according to a 2D error table and the M lens images from an image capture module that captures a X-degree horizontal field of view and a Y-degree vertical field of view;
generating M face images according to the M lens images, a first vertex list and the P optimal warping coefficients;
determining a seam for each of N seam regions; and
stitching two overlapping seam images for each seam region to generate a stitched seam image according to its corresponding seam;
wherein each face image comprises z seam images and a main image, and each seam region is located between two neighboring main images in the projection image;
wherein the 2D error table comprises multiple test warping coefficients and corresponding multiple accumulation pixel value differences in the P control regions;
wherein the P control regions are respectively located in the N seam regions that are respectively located in N overlap regions of the M face images;
wherein the first vertex list comprises a plurality of first vertices with their first data structures that define a first vertex mapping between a single lens image and the projection image, and wherein 1⇐z⇐2, M>=2, N>=1, P>=3, X>=360 and Y<180.
