ABSTRACT:
A scanner includes a scan flatbed, an optical module, a driving source, and an exposure control unit. The scan flatbed is for carrying a to-be-scanned document. The optical module includes a photo sensing device, for reading N scan lines of the to-be-scanned document. The driving source, used for driving the optical module, includes an encoder for outputting a position signal corresponding to a position of the optical module. The exposure control unit, including a timer, controls exposure time for each scan line to be constant according to the position signal. The scan method includes driving the optical module to read the scan lines of the to-be-scanned document and output the corresponding position signal; and controlling the photo sensing device to read each scan line of the to-be-scanned document for a constant period of time according to the position signal.
