Communication apparatus, communication system, and method for controlling data communication

A communication system comprising a transmission apparatus and a communication apparatus,

• the communication apparatus including:
• a first receiver to receive first image data from the transmission apparatus;
• and
• first circuitry to:
• determine, by analyzing the received first image data, an image data type of the received first image data from among a plurality of image data types;
• determine the transmission data capacity to be used for transmission of second image data based on the determined image data type of the received first image data;
• and
• send a notification to the transmission apparatus, the notification requesting the transmission apparatus to the second image data based on the determined transmission data capacity, and
• the transmission apparatus including:
• a transmitter to transmit the first and second image data to the communication apparatus;
• a second receiver to receive the notification from the communication apparatus;
• and
• second circuitry to change the transmission data capacity when transmitting the second image data to the communication apparatus,
• wherein the communication apparatus outputs the second image data that the transmission apparatus transmits based on the notified transmission data capacity.

A method for controlling data communication, comprising:

• receiving first image data from a transmission apparatus;
• determining, by analyzing the received first image data, an image data type of the received first image data from among a plurality of image data types;
• determining a transmission data capacity to be used for transmission of second image data at the transmission apparatus based on the determined image data type of the received first image data;
• sending a notification to the transmission apparatus, the notification requesting the transmission apparatus to transmit the second image data based on the determined transmission data capacity;
• and
• outputting the second image data that the transmission apparatus transmits based on the notified transmission data capacity.
