We proposed a resolution enhanced integral imaging display method using two micro-lens arrays (MLA) with different focal lengths for capturing and display respectively. An elemental image array (EIA) is captured with MLA of focal length of f(1) and a processed EIA is displayed with MLA of focal length of f(2) which is larger than f(1). We enlarge the "effective area" in processed EIA to increase the information obtained by viewer, in other words, enhance the viewing resolution. The two micro-lens arrays for capturing and display are g and mg distant from display device respectively, and we can get m(2) times resolution enhancement.
