Patent ID: 7054040

Claim:
An image-processing device comprising: a first reading module which reads a first signal in a main scanning direction of an image of a document; a second reading module which reads a second signal in the main scanning direction of the image of the document; a scanning module including a carriage which relatively moves the first and second reading modules and the image of the document to make the first and second modules scan the image of the document in its sub-scanning direction; a scanning-control-condition selecting module which selects scanning control conditions of the scanning module in accordance with a plurality of read magnifications preset as read magnifications by the first and second reading modules to the document; a first setting module which sets the scanning control conditions selected by the scanning-control-condition selecting module to a plurality of control conditions in accordance with the read magnification of the first reading module; a second setting module which sets the scanning control conditions selected by the scanning-control-condition selecting module to a plurality of control conditions in accordance with a read magnification of the second reading module; and an operating module which, at least when set to a read magnification other than said plurality of read magnifications preset, performs an operating process to compute image data having a corresponding read magnification other than said plurality of read magnifications preset to the sub-scanning direction in accordance with the first and second signals read by the first and second reading modules at any one of said plurality of read magnifications preset, wherein, the operating process by the operating module.
