An image scanning apparatus and method accurately sense a leading edge and a tail edge of a scanned document and determine the leading margin and the tail margin of the document. The image scanning method includes feeding the document to a scanning position through a feeding path according to a command to scan the document; operating a sensor unit disposed on the feeding path according to a location of the document; scanning the document in response to operation of the sensor unit; sensing a leading edge of each document using a document sensing pattern disposed oppositely to the scanning unit; and scanning the document when the leading edge of the document is sensed. |
