Patent ID: 8724193

Claim:
A scanner comprising: a scan device; a storage device configured to store a plurality of patterns of scan setting data, and a plurality of preview image files corresponding to the plurality of patterns of scan setting data; and a controller configured to execute: causing the scan device to perform a pre-scan so as to obtain pre-scan data from the scan device; creating, using the pre-scan data, the plurality of preview image files corresponding to the plurality of patterns of scan setting data stored in the storage device, wherein in each of the plurality of preview image files, a corresponding pattern of scan setting data among the plurality of scan setting data is reflected; storing the created plurality of preview image files in the storage device in a manner in which the plurality of preview image files are viewable by an external device via a network; receiving, from the external device via the network, an acquisition request for one preview image file which is selected from among the plurality of preview image files; causing the scan device to start performing a precise scan when the acquisition request is received from the external device via the network, so as to create a precise scan image file in which a pattern of scan setting data corresponding to the one preview image file among the plurality of patterns of scan setting data is reflected; and sending the created precise scan image file to the external device via the network, wherein the plurality of patterns of scan setting data includes: a first pattern of scan setting data including a first scan resolution; and a second pattern of scan setting data including a second scan resolution which is higher than the first scan resolution, and wherein the plurality of preview image files includes: a first preview image file which reflects the first pattern of scan setting data and represents a first preview image; and a second preview image file which reflects the second pattern of scan setting data and represents a second preview image which has a larger vertical and horizontal size than the first preview image.
