Patent ID: 8179574

Claim:
An image reading device comprising: a tag information reading unit for reading information recorded in an IC tag by performing radio communication with the IC tag attached or embedded at a predetermined position of a medium that becomes a target of image reading; an image reading unit for creating image data of an image recorded on the medium by scanning the medium, wherein the image reading unit determines a scanning area from a plurality of scannable areas based on area information related to the content on the medium among information read by the tag information reading unit from the IC tag and scans the determined scanning area, an image data processing unit for performing a process corresponding to the area information with respect to the image data created by the image reading unit, wherein when the determined scanning area comprises a plurality of scanning areas having images of differing types at different positions, the tag information reading unit reads positional information and type information of an image for every area of the plurality of scanning areas from the IC tag, and the image data processing unit extracts each image data for every area of the plurality of scanning areas from the image data based on the positional information, determines a compression method with respect to each image data for every area based on the type information, and compresses each image data for every area by the determined compression method, wherein the determined compression method differs according to the differing type of image.
