  • the zoom-in limit is reached, the control unit 2 completes the zoom scroll function.
  • the user keeps touching and moving one finger for more than the second set time to activate the zoom scroll function and touching the finger to move the map image.
  • the map image can be scrolled, and the map image can be subsequently scrolled out.
  • the user can zoom in on the map image by releasing the finger.
  • FIG. 9 to 12 show the transition of the map image related to the series of processes described above. Characters such as “A”, “B”, and “C” in FIG. 9 and subsequent figures indicate blocks of the map image. Further, the positions on the touch screen touched by the user shown in FIG. 9 and subsequent figures are examples, and the same is true even if the user touches any position on the touch screen.
  • the control unit 2 activates the zoom scroll function. First, the scroll of the map image is started, and the map image is scrolled in the direction from the center of the display area to the lower left (the direction opposite to the upper right where the user touches the finger with respect to the display area center).
  • the control unit 2 starts zoom-out scrolling of the map image, and the map image is displayed simultaneously with zooming out. Scroll in the direction from the center of the area to the lower left, and the display mode shown in FIG. That is, the “E” block displayed at the location where the user continues to touch the finger moves to the lower left, and the “L” block is newly displayed at the location where the user continues to touch the finger.
  • the control unit 2 starts zooming in the map image, and the map image zooms in, resulting in the display mode shown in FIG. That is, the block around “I” displayed near the center of the display area immediately before zooming in is enlarged and displayed.
  • FIG. 10B the block displayed near the center of the display area immediately before zooming in is displayed in an enlarged manner, but near the location where the user touched the finger just before zooming in started. The displayed block may be enlarged and displayed.
  • the control unit 2 dynamically changes the scroll direction and the scroll speed as described above when the user moves while touching one finger while scrolling the map image and during zoom-out scroll. That is, in the display mode shown in FIG. 11A, when the map image is scrolled, when the user moves from the upper right to the upper left of the touch screen while touching one finger, the control unit 2 changes the scroll direction and the scroll speed.
  • the display mode is changed dynamically to the display mode shown in FIG. In FIG. 11, the scroll direction is from the center of the display area to the lower left before the user moves the finger. However, after the user moves the finger, the scroll direction is from the center of the display area to the lower right. . In the display mode shown in FIG.
  • the control unit 2 when the user moves one finger from the upper right to the upper left of the touch screen during the zoom-out scroll of the map image, the control unit 2 also changes the scroll direction and The scroll speed is dynamically changed, and the display mode shown in FIG. Also in FIG. 12, the scroll direction is from the center of the display area to the lower left before the user moves the finger, but after the user moves the finger, the scroll direction is from the center of the display area to the lower right.
  • 11A and 12A show display modes immediately before the user starts to move the touch position, and FIGS. 11B and 12B end the movement of the touch position by the user. Although the display mode immediately after is shown, the control unit 2 dynamically changes the scroll direction and the scroll speed even when the user moves the touch position.
  • the control unit 2 resumes scrolling following the zoom-out scroll of the map image.
  • the user can scroll the map image by continuously touching the finger even after zooming and scrolling the map image.
  • FIG. 13 and FIG. 14 show the transition of the map image related to the series of processes described above.
  • the control unit 2 resumes scrolling the map image, The image scrolls in the direction from the center of the display area to the lower left, and the display mode shown in FIG. That is, the “L” block displayed at the location where the user continues to touch the finger moves to the lower left, and the “N” block is newly displayed at the location where the user continues to touch the finger.
  • the control unit 2 also starts zooming in the map image in this case, and the map image zooms in, resulting in the display mode shown in FIG. .
  • the control unit 2 displays the map image. After zooming in, the zoom scroll function is once completed, and the zoom scroll function is restarted from the scale at that time. Accordingly, the user can repeat the zoom scroll function and restart by touching the finger during zooming in.
  • FIG. 15 shows the transition of the map image related to the series of processes described above.
  • the control unit 2 finishes zooming in the map image and temporarily ends the zoom scroll function. , Restart the zoom scroll function from the current scale. Thereafter, when the user continues to touch one finger, the control unit 2 starts scrolling the map image, and the display mode shown in FIG. 15B is obtained, and the map image is switched according to the user operation.
  • the scroll direction and the scroll speed are recalculated according to the angle and the distance from the center of the display area to dynamically change the scroll direction and the scroll speed.
  • the portable information communication terminal 1 is assumed to have an operation mode in which only the thumb is touched on the touch screen while holding the housing 1a with four fingers other than the thumb when operating with one hand.
  • an operation mode in which only the thumb is touched on the touch screen it is difficult to activate a zoom-out or zoom-in function that has been conventionally operated with two fingers.
  • two fingers are used.
  • the zoom-out function and the zoom-in function can be utilized without necessity, and the scroll direction and scroll speed can be changed during the zoom-out scroll. As a result, the operability can be greatly improved.
  • the present disclosure is not limited to the above-described embodiment, and can be modified or expanded as follows. A plurality of modified examples may be combined.
  • the present invention is not limited to a portable information communication terminal, and may be applied to a fixed type device. For example, the user may touch the touch screen using a pen-shaped tool.
  • the display image is not limited to a map image and may be any image.
