    • 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.
    • 一种具有自动文件馈送模式中的自动背景去除(ABR)功能的图像形成装置及其操作控制方法。 图像形成装置包括:第一移动单元,用于将装载在文件托盘中的文件从第一位置移动到第二位置; 第二移动单元,用于将包含光源的托架从第一位置移动到第二位置; 图像处理部分,用于将所述文档的图像处理成预定图像数据; 以及控制部分,用于控制图像处理部分,以处理由固定在第一位置处的托架读出的文档的特定部分的图像,并处理由固定在第二位置的托架读出的文档的整个图像 在使用基于特定部分的图像处理结果选择的预定对比度均衡模式。 本发明的总体构思可以在自动送纸器模式下调节托架和文件的运动以执行自动背景去除功能,以在光源固定的同时移动文档来读出文档的图像。
