Controlling device for controlling scan performing unit

摘要

A controlling device (30) for controlling a scan performing unit (20) may determine a specific optical resolution from among a plurality of optical resolutions by utilizing specific information given from a user, cause the scan performing unit (20) to perform a scan of a document in accordance with the specific optical resolution, perform an analysis of scan data obtained by the scan of the document, determine an output resolution based on a result of the analysis of the scan data, converting the scan data indicating the specific optical resolution into image data indicating the output resolution in a case where the output resolution is not identical to the specific optical resolution, and create a file including the image data indicating the output resolution.
