Therefore, the display magnification of the partial image displayed in the first display area 6 at the same magnification or enlargement is set to a fixed magnification, and the display reduction ratio of the peripheral image to be reduced or enlarged in the second display area 7 is fixed. When the magnification is set, the range of the peripheral image displayed in the second display area 7 is always a constant range with respect to the partial image displayed in the first display area 6. In addition, when the display reduction ratio of the peripheral image to be reduced or enlarged to the second display area 7 is set to a variable magnification, each small area 7U, 7D, 7R, 7L of the second display area 7 ... The display reduction ratio is set for each, for example, the area ratio of each small area 7U, 7D, 7R, 7L, ... Of the second display area 7 corresponding to the size of each peripheral image corresponding to each movement direction. By setting each display reduction ratio so that each peripheral image is displayed for each small area 7U, 7D, 7R, 7L, ... Of the corresponding second display area 7, the entire image is displayed. It can be displayed on one screen. By doing this, you can move to know the image of the peripheral part that is not displayed on the display 1 screen, and it is displayed on the display screen at all.

【0022】

In addition, when the image displayed on the display 1 screen is moved vertically, horizontally, or diagonally and displayed, the display reduction ratio set in the small area of the second display area 7 on the opposite side of the moving direction is equal. The movement of the image is stopped when it is doubled. For example, in order to move the image displayed on the display 1 screen upward, if a display 8D indicating the moving direction such as an arrow or a mark displayed below the first display area 6 is instructed, the first display area 6 The size of the peripheral image displayed in the small area 7D of the second display area 7 located below gradually becomes smaller, and the area of the small area 7D of the second display area 7 corresponding to the size of the peripheral image. When the display reduction ratio is changed so that the peripheral image is displayed in the small area 7D of the corresponding second display area 7 according to the ratio, the time point at which the display reduction ratio becomes the same becomes the same. At this point, the movement of the image is stopped. Further, each small area 7U, 7D, 7R, 7L, ... Set for each small area 7 of the second display area 7 indicates a moving direction such as an arrow or a triangle mark only in each small area where the display reduction ratio is the reduction magnification. Display 8U, 8D, 8R, 8L, ... are displayed overlaid on the peripheral image, and each small area where the display reduction ratio is the same magnification is displayed with an arrow or mark indicating the moving direction. Avoid doing 8R, 8L, ... Then, each small area 7U, 7D, 7R, 7L, ... Enables the interactive function that interacts with each part of the peripheral image displayed in each small area 7U, 7D, 7R, 7L, ..., Where the display reduction ratio set for each is the same magnification. By doing so, the display area of one display screen can be used more effectively.
