PROBLEM TO BE SOLVED: To improve operability of input of an image and positioning.SOLUTION: In an image display device 1 having a main device 3 and a terminal device 4, data on an additional image 6 to be displayed in a processed area 15 of a main side display surface 14 is prepared by a terminal side control unit 22. Then, a similar figure 25 representing the processed area 15 is displayed on a terminal side display surface 24. A position within the similar figure 25 within the terminal side display surface 24 is instructed from a terminal side operation unit 21. On the basis of a relative relation between the similar figure 25 within the terminal side display surface 24 and the instructed position within the terminal side display surface 24, a display proposed position 7 of the additional image 6 within the processed area 15 of the main side display surface 14 is determined. Data on the additional image 6 and data on the display proposed position 7 are provided from the terminal device 4 to the main device 3. A main side control unit 12 of the main device 3 displays the additional image 6 at the display proposed position 7 within the processed area 15 within the main display surface 14 of a main side display unit 10. |
