Patent ID: 8228516

Claim:
An image formation device capable of forming a plurality of reduced images on an output medium, comprising: an input data acquisition unit which acquires input data; a recognizability judgment unit which judges whether each reduced image to be formed corresponding to each piece of input data acquired by the input data acquisition unit is recognizable to a user or not based on the input data and size of the reduced image to be formed; and a reduced image formation unit which forms the reduced images that are judged to be recognizable by the recognizability judgment unit on the output medium while prohibiting the formation of the reduced images that are judged to be unrecognizable by the recognizability judgment unit, wherein the reduced image formation unit includes: a reduced image data acquisition unit which acquires reduced image data, to be used for forming the reduced image that is judged to be recognizable by the recognizability judgment unit, from the input data corresponding to the reduced image when the reduced image data is included in the input data; and a reduced image data generation unit which generates the reduced image data, to be used for forming the reduced image that is judged to be recognizable by the recognizability judgment unit, based on the input data corresponding to the reduced image when the reduced image data is not included in the input data, wherein the reduced image formation unit forms the reduced image of each piece of input data on the output medium according to the reduced image data acquired by the reduced image data acquisition unit or generated by the reduced image data generation unit.
