Abstract:
1. An image input/output control apparatus for performing input/output of image data, comprising: a first image processing unit adapted to generate a plurality of first image data packets by converting image data inputted by an image input apparatus; a second image processing unit adapted to perform image processing on the plurality of first image data packets generated by said first image processing unit to generate a plurality of second image data packets; a third image processing unit adapted to generate image data based on either the plurality of first image data packets or the plurality of second image data packets and to output the generated image data to an image output apparatus; a control unit adapted to control storing process for storing the plurality of first image data packets and the plurality of second image data packets to a storage apparatus and to control reading process for reading the plurality of first image data packets and the plurality of second image data packets from the storage apparatus; and a data transfer unit adapted to connect said plural image processing units and said control unit in a ring-type formation and to perform data transfer between said plural image processing units and said control unit unidirectionally, wherein said data transfer unit transfers the first image data packet to said second image processing unit in a case where an identification information for identifying said second image processing unit is added to the first image data packet, transfers the first image data packet to said third image processing unit in a case where the identification information for identifying said third image processing unit is added to the first image data packet, and transfers the second image data packet to the third image processing unit in a case where the identification information for identifying said third image processing unit is added to the second image data packet.
