1. A scanning apparatus for scanning an object, comprising: a casing, comprising a first flatbed and a second flatbed, the first flatbed being for placing the object and comprising a scanning area, and the second flatbed adjacent to the first flatbed; a scanning module, disposed in the casing and under the first flatbed for capturing the object on the scanning area so as to generate a first image from a first scanned page and a second image from a second scanned page; at least one sensor, disposed in the casing for sensing the object so as to send a detection signal; and a control unit, electrically connected to the scanning module and the sensor for actuating the scanning module to scan and generate the first image and the second image when the control unit receives the detection signal; wherein the control unit further comprises a recognition unit for recognizing whether the first image along with the second image are continuous according to the orientation of the first image and the second image, as the first image and the second image are in a same orientation and recognized by the recognition unit to be discontinuous, the control unit generates an insertion image between the first image and the second image.
