An image scanning method, applied to a document, performs a preliminary scanning operation to distinguish the document into areas uniformly containing a same color level and scanned areas containing different color levels. An image scanning sequence is subsequently performed, during which an area of the document to be scanned is skipped if it has been determined as an area uniformly having a same color level. A color code value corresponding to the uniform color level of this area is consequently stored in a corresponding memory zone. The above image scanning sequence is executed until the scanning of the document is completed.
