An image scanning method used in a scanner. The scanner includes a housing, a transparent platform set on the housing for a document to be placed on, a scanning module installed inside the housing for scanning the document, and a step motor for driving the scanning module step by step so as to scan the document. After completing a first scanning pass, the scanning module moves a predetermined distance, which corresponds to non-integer steps of the step motor so that when the scanning module performs a second scanning pass, sampling positions of the second scanning pass are different from sampling positions of the first scanning pass.
