1. An information processing apparatus comprising: an image reading section that reads a document image of an original document; an operating section through which instructions on various operations are entered by a user; a communication section that performs data communication with another information processing apparatus and acquires a plurality of objects from the another information processing apparatus; a synthesizing region acceptance section that accepts, based on an instruction entered through the operating section, specification of an object synthesizing region in the document image obtained by the reading of the original document by the image reading section, the object synthesizing region being a region of the document image in which the object is to be synthesized; and an image creating section that synthesizes one of object images representing the plurality of objects acquired by the communication section in the object synthesizing region of the document image the specification of which has been accepted by the synthesizing region acceptance section, thus creating, for the plurality of objects, individual outputting synthetic images by performing, on all of the plurality of objects acquired by the communication section, synthetic image creation processing that creates an outputting synthetic image containing the one object image synthesized thereinto.
