Abstract:
1. An image reading apparatus, comprising: an original reading unit configured to read image data from the original; a driving motor configured to drive at least one of the original reading unit and the original in a sub-scan direction so that the original reading unit scans the original to read the image data; an image data storing unit configured to store the image data read by the original reading unit; an image processing unit configured to restore image data of the original from the image data stored by the image data storing unit; and a reading operation control unit configured to control a rotational speed of the driving motor, wherein: when an amount of the image data stored by the image data storing unit becomes equal to or more than a predetermined amount, the reading operation control unit reduces the rotational speed of the driving motor according to driving control data provided for each of current rotation angles of the driving motor, for finally stopping the driving motor at a predetermined rotation angle, and for reducing a speed in the sub-scan direction at which the original reading unit reads the original, and the image processing unit thins out main scan line data from the image data stored by the image data storing unit according to thin-out data provided for each driving control data to restore the image data of the original.
