Patent ID: 7454540

Claim:
A data transferring system that transfers image data based on the PCI Express standard by synchronizing with a line synchronizing signal or a frame synchronizing signal, comprising: a first packet gathering unit configured to transfer first image data packets by causing a period between the first packets to be transferred in one cycle of the synchronizing signal to be shorter than a time that is required to transit from a link state L 0 to a link state L 0 s and from the link state L 0 s to the link state L 0 ; a second packet gathering unit configured to transfer second image data packets by causing a period between the second packets to be transferred in one cycle of the synchronizing signal to be shorter than the time that is required to transit from the link state L 0 to the link state L 0 s and from the link state L 0 s to the link state L 0 ; and a delay controlling unit configured to control a delay between a last packet transferred by the first packet gathering unit and a first packet transferred by the second packet gathering unit to be shorter than the time that is required to transit from the link state L 0 to the link state L 0 s .
