摘要： A communication apparatus includes a receiver and circuitry. The receiver receives image data from a transmission apparatus. The circuitry identifies an image data type of the image data received by the receiver, and determines a transmission data capacity to be used for transmission of the image data at the transmission apparatus based on the identified image data type. The circuitry further sends a notification to the transmission apparatus, the notification requesting the transmission apparatus to transmit the image data based on the determined transmission data capacity, and outputs the image data that the transmission apparatus transmits based on the notified transmission data capacity.
