Communication device, communication system and computer readable medium

A image processing device, comprising:

• a first image control device;
• and
• a second image control device;
• the first image control device, including:
• a division device that divides first image data to be transmitted to the second image control device via a transmission path including a plurality of lanes into a plurality of second image data;
• a transmission device that forms image data packets from the plurality of second image data and distributes, in parallel, the image data of the plurality of second image data divided by the division device to either one of the plurality of lanes, and transmits them to the second image control device;
• and
• an error notification reception device that receives an error notification when an error is detected from one of the plurality of second image data received by the second image control device, wherein the second image data excludes packets, and
• wherein when the error notification reception device receives the error notification, the division device divides second image data, in which the error is detected, into a plurality of third image data, and the transmission device forms image data packets from the plurality of third image data and retransmits the second image data to the second image control device by distributing the image data packets of the plurality of third image data divided by the division device to either one of the plurality of lanes, and
• wherein the second image control device including:
• a reception device that receives the plurality of second image data or the plurality of third image data from the first image control device;
• an error detection device that detects the error from the plurality of second image data received from the first image control device;
• and
• an error notification device that notifies the first communication device of the error when the error detection device detects the error from one of the plurality of second image data.

A non-transitory computer readable medium storing a program causing a computer to execute a process, the process comprising:

• dividing first image data to be transmitted to an image control device via a transmission path including a plurality of lanes into a plurality of second image data via;
• forming image data packets from the plurality of second image data;
• distributing the image data packets of the plurality of second image data divided in the dividing to either one of the plurality of lanes, and transmitting in parallel them to the image control device;
• and
• receiving an error notification when an error is detected from one of the plurality of second image data received by the image control device;
• wherein when the error notification is received in the receiving, second image data in which the error is detected is divided into a plurality of third image data, and the second image data is retransmitted by distributing the plurality of third image data to either one of the plurality of lanes, and
• wherein the second image data excludes packets.
