Abstract
A scanning device includes a mode for generating a reproduced image on a standard page size from a large-sized original image. In this mode, the sampling rate of the scanning device in a motion direction is reduced. In addition, the captured image data in the sensor direction is downsampled by some factor. Position data that is generated as the image data is captured is also modified in accordance with the downsampling factor. A reproduced image is then generated from the modified image and position data and printed at a standard resolution.
