Image reading system, information processing apparatus, image reading apparatus and computer readable medium

An information processing apparatus comprising:

• a wireless state detector for detecting a first wireless state between the information processing apparatus and an access point in a wireless network;
• a wireless state information receiver for receiving, from an image reading apparatus, information of a second wireless state between the image reading apparatus and the access point in the wireless network;
• a packet length determining module for determining a packet length such that the packet length in forwarding image data obtained by reading a document by the image reading apparatus to the information processing apparatus via the wireless network is reduced according to a degradation in either one of the first wireless state and the second wireless state;
• and
• a packet length information transmitter for transmitting, to the image reading apparatus, packet length information corresponding to the determined packet length.

An image reading apparatus comprising:

• a reader for reading a document to generate image data;
• a wireless state detector for detecting a wireless state between the image reading apparatus and an access point in a wireless network;
• a wireless state information transmitter for transmitting information of the wireless state to an information processing apparatus;
• a packet length information receiver for receiving, from the information processing apparatus, packet length information of a packet length determined by the information processing apparatus in accordance with the wireless state in forwarding the image data to the information processing apparatus via the wireless network;
• and
• an image data transmitter for storing the image data in packets with the packet length corresponding to the packet length information and transmitting the packets to the information processing apparatus via the wireless network.

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

• detecting a first wireless state between the computer and an access point in a wireless network;
• receiving, from an image reading apparatus, information of a second wireless state between the image reading apparatus and the access point in the wireless network;
• determining a packet length such that the packet length in forwarding image data obtained by reading a document by the image reading apparatus to the computer via the wireless network is reduced according to a degradation in either one of the first wireless state and the second wireless state;
• and
• transmitting, to the image reading apparatus, packet length information corresponding to the determined packet length.
