Abstract
An image processing method for receiving M lens images and generating a projection image is disclosed. The method comprises: determining P optimal warping coefficients of P control regions in the projection image according to a 2D error table and the M lens images from an image capture module; generating M projection 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 to generate a stitched seam image for each seam region according to its corresponding seam. The 2D error table comprises multiple test warping coefficients and multiple accumulation pixel value differences in the P control regions. The P control regions are respectively located in the N seam regions respectively located in N overlap regions, where M>=2, N>=1 and P>=3.
