The invention discloses an image processing method, system and shooting terminal for optimizing edge aliasing. The method herein comprises the following steps: conducting smooth processing on a contour of which an image is to be processed to obtain a smooth closed contour curve, using the closed contour curve to conduct morphological reconstruction and Gaussian Blur processing on the image to be processed to obtain a fuzzy image of a binary image, then conducting a one-time gray scale statistics and threshold value processing on all the edges of the fuzzy image to obtain a first gray scale mapping table, and in accordance with the first gray scale mapping table, calculating so as to obtain a gray scale image, and further conducting a second gray scale statistics and threshold value processing on the aliasing edge of the gray scale image to obtain a second gray scale mapping table, and in accordance with the second gray scale mapping table, adjusting the aliasing edge to obtain an anti-aliasing image.
