| Abstract: | The principle of digital image scaling is theoretically analysed at first. Based on that, the simplified formula of image scaling is proposed, which is more suitable to engineering applications. Then, taking the digital automatic printer as example, image scaling implemented by hardware is introduced in detail. At last, the errors and distortions produced in image scaling are analyzed. |

| Keywords: | digital image processing image scaling digital automatic printer |
