Patent ID: 7808682

Claim:
An image scanning system comprising: an image-capturing device that executes a preliminary image-capturing operation and a main image-capturing operation on a scan original to capture an image of the scan original and outputs image signals; an image processing circuit that executes image processing on the image signals; an image signal output device that outputs the image signals having undergone the image processing; a storage device in which previous actual lengths of required time to process a previous scan original are stored in memory in correspondence to each of the steps, the actual length of time being a length of time having been required to actually execute steps of, at least, the preliminary image-capturing operation, the main image-capturing operation, the image processing and the image signal output; a calculation device that calculates a total of lengths of required time to execute steps of, at least, the preliminary image-capturing operation, the main image-capturing operation, the image processing and the image signal output to process a new scan original based upon the previous actual lengths of required time for executing each corresponding step, which have been stored into the storage device; and a calculation result output device that outputs the estimated length of required time as calculation results obtained at the calculation device such that the estimated length of required time is displayed on an external monitor.
