Claim 2:
3. The method according to claim 1, wherein the step of determining the P optimal warping coefficients comprises:
determining the test warping coefficients according to an offset of a lens center of the image capture module relative to its system center;
modifying texture coordinates of each lens image in a second data structure of each second vertex in a second vertex list according to the test warping coefficients to generate a third vertex list;
measuring the accumulation pixel value differences in the P control regions according to the third vertex list and the M lens images;
repeating the steps of modifying and measuring until all the test warping coefficients are processed to form the 2D error table; and
determining the optimal warping coefficient for each control region according to at least one local minimum among the accumulation pixel value differences of its one or two closest control regions in the 2D error table;
wherein the second vertex list comprises multiple second vertices with their second data structures that define a second vertex mapping between the M lens images and the projection image; and
wherein the third vertex list comprises multiple third vertices with their third data structures that define a third vertex mapping between the M lens images and the projection image.
