Image communication apparatus, image communication system, and control program for image communication

An image communication system that transmits and receives image data via a network, the image communication system comprising:

• an image-data input unit through which image data to be transmitted and received is input;
• a condition-information obtaining unit configured to obtain condition information on a difference condition for determining a difference between image data obtained by scanning an image output based on the image data and the image data in an apparatus that receives the image data, in accordance with an operation by a user;
• an image-data transmitting unit configured to transmit obtained image data and the condition information;
• an image-data receiving unit configured to receive transmitted image data;
• a storing unit configured to store therein the image data received by the image-data receiving unit;
• an output unit configured to output the image data stored in the storing unit;
• a scanning unit configured to scan the image data output by the output unit;
• a difference extracting unit configured to extract a difference between the image data scanned by the scanning unit and the image data stored in the storing unit;
• a difference determining unit configured to determine whether the difference extracted by the difference extracting unit satisfies a predetermined condition based on the condition information obtained together with the image data;
• and
• a control unit configured to control transmission of a message, to a transmission source of the image data, based on a result determined by the difference determining unit.

A non-transitory control program for causing an information processing apparatus to operate as an image communication apparatus that receives image data via a network, the control program causing the information processing apparatus to execute:

• receiving image data;
• storing received image data;
• outputting stored image data;
• scanning output image data that is output at the outputting;
• extracting a difference between scanned image data and the stored image data;
• determining whether extracted difference satisfies a predetermined condition based on condition information obtained together with the image data;
• and
• transmitting a message to a transmission source of the image data based on determined result that is determined at the determining;
• wherein the extracting extracts a color difference, and
• wherein the condition information includes information specifying a hue range, and the extracting extracts the color difference when an image included in the image data stored in the storing belongs to the hue range specified in the predetermined condition.
