Abstract
A method of compensating for color differences between adjacent lens images in a panoramic image is disclosed. The method comprises: calculating color differences of each pair of character regions between any two adjacent lens images out of multiple lens images from a multiple-lens camera according to average color values of the character regions, each character region having a character point; determining color adjustment amounts of character points in each lens image according to the color differences of each pair of character regions; calculating a color adjustment amount of an element according to positions of the element and its two adjacent character points and the color adjustment amounts of the two adjacent character points.
