1. An automatic scanning parameter setting device capable of extracting a plurality of scanning parameters from a pile of scan images so that the images can be scanned in batches, wherein the automatic scanning parameter setting device is a scanner comprising: an image input device mounted on the scanner for inputting the scan images, wherein a portion of the scan images have a set parameter format that includes a plurality of scan parameter values; an analysis device for determining whether a particular scan image has the scanning parameter values and performing a scanning parameter analysis on those images having recorded scanning parameter values; and a control unit that utilizes the analyzed scan parameter values to set scanning parameters on the scan images with recorded scan parameter values currently undergoing a scanning operation as well as the ordered scan images after the scan images with recorded scan parameter values but without recorded scan parameter values.
