Abstract: In a multi-stage scanning method for increasing a scanning speed and enhancing an image quality, an optical module is firstly moved from a start position to a forward-internal position in a forward direction, and then enabled to scan a first portion of a document to obtain a first image until the module reaches a forward-boundary position. Then, the module is moved from the forward-boundary position to an end position in the forward direction. Next, the module is moved from the end position to a reverse-internal position in a reverse direction, and then enabled to scan a second portion of the document to obtain a second image until the module reaches a reverse-boundary position. Then, the module is moved from the reverse-boundary position to the start position, in the reverse direction, and then stopped. Finally, the first and second images are stitched into a complete image.

Abstract: The scanning apparatus includes a movable chassis and a main board fixed on the body. A charge-coupled device module and a front end processing device are disposed on the chassis. An application-specific integrated circuit is positioned on the main board. After the charge-coupled device module detects a light analog signal, the application-specific integrated circuit communicates with the front end processing device through a command interface. Therefore, the light analog signal is converted into the light digital signal by the front end processing device, and then the light digital signal encoded into low voltage differential signaling form is transmitted to the application-specific integrated circuit for proceeding the subsequent image processing.

Abstract: A duplex scanning device includes a casing, a transporting mechanism, a scanning unit and a scanning unit rotating mechanism. The transporting mechanism transports a sheet along a transporting passageway, which includes a front passageway, a middle passageway and a rear passageway. The scanning unit rotatably mounted on the casing scans the sheet in the middle passageway. The transporting mechanism transports the sheet from the front passageway to the rear passageway through the middle passageway so that the scanning unit scans a front side of the sheet. Then, the scanning unit rotating mechanism rotates the scanning unit by substantially 180 degrees. Next, the transporting mechanism transports the sheet from the rear passageway to the front passageway through the middle passageway so that the scanning unit scans a back side of the sheet.

Abstract: A sheet-fed double-sided document scanner is disclosed and includes a first image-capturing assembly, a second image-capturing assembly, a sheet-transporting mechanism, a power receiving interface, and a control circuit. The scanner switches scanning modes according to a power input. The sheet-transporting mechanism transports a document past the first image-capturing assembly and the second image-capturing assembly. The power receiving interface receives power. When a power level of the received power is less than a default threshold level, the control circuit controls the scanner to scan a first side and a second side of the document in a first mode. When the power level of the received power reaches the default threshold level, the control circuit controls the scanner to scan the first side and the second side of the document in a second mode.
