Abstract

An image-forming apparatus having an Automatic Background Removal (ABR) function in an automatic document feeder mode and an operation control method thereof. The image-forming apparatus includes a first movement unit to move a document loaded in a document tray from a first position to a second position; a second movement unit to move a carriage containing a light source from the first position to the second position; an image processing part to process an image of the document into predetermined image data; and a control part to control the image processing part to process an image of a specific portion of the document read out by the carriage fixed at the first position and to process an entire image of the document read out by the carriage fixed at the second position in use of a predetermined contrast equalization pattern selected based on a image processing result of the specific portion. The present general inventive concept can adjust the movements of the carriage and a document to perform the Automatic Background Removal function in the automatic document feeder mode to read out the image of the document with the document moving while the light source is fixed.
