A data stream input from an image processing device (20) connected with a data transfer device (10) by means of an IEEE 1394 isochronous transmission is converted into an outputting color signal mode and PCI transferring data by a converter circuit (219), and image data from the converter circuit (219) is DMA-transmitted via a PCI bus (215) while performing an address control with a PCI bridge circuit (216B) as a bus master and is written into a graphic memory (221) via a graphic control circuit (220). Then, image data is read from the graphic memory (221) by means of the graphic control circuit (220), for transferring to an electronic apparatus (30).
