摘要

An image reading apparatus including: a reading device; a display device; an operable portion; an outputting portion which outputs the image data; an image-data storing portion which successively stores a prescribed amount of the image data; a reference-range-information storing portion which stores reference-range information that is required to determine a reference range of the image data; a reference-range managing portion which determines the reference range and which successively updates the information such that the reference range is successively updated at a prescribed timing by a prescribed size; a display controlling portion which controls the display device to display the display image; a timing controlling portion which controls updating intervals at which the reference range is updated; a command detecting portion which detects a specific command; and an output-range determining portion which determines an output range of the image data.
