PROBLEM TO BE SOLVED: To provide a remote control technique capable of suppressing deterioration of visibility due to superposition display.SOLUTION: An image formation device identifies an image to be displayed in a portable terminal 50 as the operation image thereof, and acquires the number of displays in the portable terminal 50. When a plurality of images are identified as the operation images and the number of displays in the portable terminal 50 is two or more, the image formation device makes a first determination that at least two images, out of a plurality of images, must be displayed individually in at least two displays out of two or more displays of the portable terminal 50, and transmits a display instruction based on the first determination to the portable terminal 50. Based on the display instruction, the portable terminal 50 displays at least two operation images (320, 340) individually in at least two displays (75, 77) of the portable terminal 50.SELECTED DRAWING: Figure 5 |
