Title: Apparatus and method of detecting a scanning range when applying assistantframes for flatbed scanners

Abstract: The present invention discloses an apparatus and a method for detecting thescanning range when applying the assistant frames in the flatbed scanners.Fixed marks allocated at the front side of the assistant frames are usedto determine the sizes of the assistant frames. The required scanningranges are thus determined according to the recognized assistant framesobtained from pre-scan. Only the front sides but whole of the assistantframes need to be pre-scanned, and thus to reduce the scanning timeinterval.
