We can refine the image of graphics, editing the image and process the color of image. In real life and work, people can refine and edit the pictures of digital from camera, and make magic effect base on the origin image. If used with software and other tools, we can conduct high-quality advertising design, creative art and 3D animation. This paper expound begin with the basic image processing principles, and discussing seven modules of processing including color adjustment, algebra, geometry calculation, and filter effects, artistic effect and distortion effect . The brightness value of each image pixel can be changed by color balance processing in accordance with the specific requirements; algebra processing can perform a mathematical process with two image; geometric processing can change the shape of the images; Base on the relationship of adjacent pixels the filter effect can change each pixel to achieve a special effect. Images can be processed into beautiful "art" by Artistic effect; Images can be deformed by distortion effect processing; Style effects belongs to destructive filter effects, reaching painting or impressionism effect through replacing each pixel. Key Words:matlab,image,image process,magic effect of image
