Abstract:
1. An image information apparatus, comprising: at least two image reading units configured to read, in parallel, images on corresponding sides of a double-sided original document and acquire image data for each of the corresponding sides; a frame memory that temporarily stores the image data read by the at least two image reading units; at least two transfer control units, each of said transfer control units corresponding to one of the at least two image reading units, and configured to transmit, in parallel and individually, the image data acquired by the corresponding image reading unit and stored in the frame memory; a primary storage unit that temporarily stores therein the image data transferred by the at least two transfer control units; a secondary storage unit that receives the image data from the primary storage unit and stores therein the received image data; a communication control unit configured to receive the image data from each of the at least two transfer control units and to transmit, in parallel, the image data to the primary storage unit via a communication path; and a selecting unit configured to determine whether the image data corresponding to both sides of the double-sided original document is to be transferred in parallel or in time series according to a storage capacity of the frame memory apparatus, wherein when the at least two image reading units simultaneously read corresponding sides of the original document, if the storage capacity of the frame memory is less than a capacity required to store one page of the image data of the original document, the selecting unit determines parallel transfer of the image data and the at least two transfer control units transfer the image data in parallel, otherwise the selecting unit determines time series transfer of the image data, and the at least two transfer control units transfer the image data in time series.
