ABSTRACT:
An image acquiring method of a scanned image is applying to an image reading apparatus having an automatic sheet-feeding function. The method includes the steps of: acquiring a first image at a scan region of the image reading apparatus by performing a sheet-feeding operation and an image reading operation; analyzing the first image to recognize an effective area and an ineffective area outside the effective area; and adjusting a timing for starting acquiring a second image in relation to size of the ineffective area, so as to reduce the size of the ineffective area in the second image.
