Patent ID: 8203771

Claim:
A control method for an image reading system comprising an image scanning apparatus configured to selectively read an original placed on an original plate as a reflective original or a transmissive original, an image processing apparatus configured to receive image data read by the image scanning apparatus and to execute image processing of the image data, and an operating unit and a display unit configured to be able to operate the image scanning apparatus and the image processing apparatus, the control method comprising: selecting an auto-mode operation of automatically determining whether the original placed on the original plate is the reflective original or the transmissive original, executing reading of the original, and image processing; determining whether the original placed on the original plate is the reflective original or the transmissive original in the auto-mode operation; accepting a user input whether the original placed on the original plate is the reflective original or the transmissive original during the determination in the auto-mode operation; executing reading of image data from the reflective original or the transmissive original in accordance with the determination in the auto-mode operation independent of the user input, or if the above user input is performed, in accordance with the user input instead of the automatic determining during the auto-mode operation; processing the read image data; displaying, in the display unit, details of processing executed in the determining and the image processing; and inputting an instruction to change the details of displayed processing, wherein when the change instruction input instructs change of a process under execution or having been already executed, the image processing is executed again from the changed process, wherein the displaying includes displaying a list of items of the image processing and also displays the item of the image processing currently under the execution, if the user input includes selecting an item from the list of items that changes the image processing under execution, it is possible to cancel the image processing under execution and return to a start process to execute image processing based on the selected item.
