Receiving device and transmitting device

A receiving device, comprising:

• a receiving unit that receives image data from a first transmitting device with which the receiving device has established a wireless communication connection;
• a display unit that displays setting data necessary for a second transmitting device which is different from the first transmitting device to establish the wireless communication connection with the receiving device and the image data;
• and
• a display control unit that controls the display of the display unit, during a period before another wireless communication connection is established between the receiving device and the second transmitting device with which no wireless communication connection is established, so that the image data is displayed on the same display region as that of the display unit that displays the setting data in a frame displaying the setting data, in frames displayed before and after the frame including the setting data, and that, when a frame including the setting data is displayed on the display unit, controls the display of the display unit so that the same setting data or a part of the same setting data is displayed on a different display region from that in which the setting data is immediately previously displayed.
