For example, when receiving the second user input in operation 430 or at the start of an operation of transferring some data to the first memory in operation 450 , the control device may turn off the display device for a time A count operation for checking progress may be performed. When the control device determines that the determined delay time has been reached according to the execution of the count operation, the control device turns on the turned-off display device, transmits the control signal to the first memory, and the control signal The first memory that has received may transmit the second image data, which is the restored data, to the display device. As another example, the control device may maintain an existing output screen of the display device instead of turning off the display device, and thus may not perform an operation of turning on the turned-off display device.

In operation 460, the device may display a second image corresponding to the second image data on the display device.

According to an embodiment, the device may display a second image corresponding to the second image data received from the first memory on the display device.

For example, the control device 101 may store the second data in the first memory 105 based on the user input, and the second data stored in the first memory 105 and the first data You can see if they are different.

For example, if the second data and the first data are different from each other, operation 607 is performed, otherwise the operation of the present embodiment may be terminated.

In operation 607 , the control device 101 may identify third data based on a difference between the second data and the first data.

For example, the third data may include data corresponding to a different part between the second data and the first data.

In operation 609 , the control device 101 may transfer the third data to the first memory 105 .

In operation 611 , the control device 101 may transmit fourth data generated based on the third data from the first memory 105 to the display device 107 .

For example, the fourth data may be data including data remaining after deleting some data different from the first data from the second data and the third data.

In operation 613 , the control device 101 may display a second image corresponding to the fourth data on the display device 107 .

For example, when the user input is an input for controlling the temperature change of 25 degrees, as shown in FIG. 6 , the value of the set temperature may be changed to 25 degrees and displayed on the display device 107 .
