  Hereinafter, when the speedometer image 12 and the tachometer image 13 are normally displayed on the image display device 10 with the touch panel 20 as shown in FIG. 2, the size of the speedometer image 12 is desired to be larger than the normal display. (That is, when the speedometer image 12 is enlarged and displayed) will be described. The enlarged display of the tachometer image 13 is the same as in the case of the speedometer image 12, and thus description thereof is omitted here.

  In this case, first, the user touches 20 places on the touch panel facing the display area of the speedometer image 12 with the user's thumb 51 and index finger 52 attached (FIG. 3A), and then FIG. As shown in b), the two fingers 51 and 52 (the thumb 51 and the index finger 52) are moved along the touch panel 20 so as to separate the thumb 51 and the index finger 52, whereby the separation between the fingers 51 and 52 is performed. The microcomputer 31 receives the operation signal corresponding to the distance.

  When the microcomputer 31 receives the operation signal that accompanies the gesture operation with the two fingers 51 and 52 at the 20 positions on the touch panel facing the display area of the speedometer image 12, the microcomputer 31 is based on the operation signal. In order to enlarge and display the speedometer image 12 (that is, to change the display form of the speedometer image 12), the enlarged display instruction signal which is the command signal is output to the graphic controller 32.

  For example, the microcomputer 31 receives the operation signal indicating that the dimension is 20 mm if the dimension of the separation distance is 20 mm in accordance with the gesture operation using the two fingers 51 and 52, Based on the operation signal, the enlargement display instruction signal is output to the graphic controller 32 in order to display the size of the speedometer image 12 at a predetermined enlargement magnification (for example, 1.2 times the normal display).

  The graphic controller 32 receives the enlargement display instruction signal and executes enlargement drawing processing of the speedometer image 12, whereby only the speedometer image 12 becomes the center point C of the speedometer image 12 in FIG. With the center (that is, the rotation center of the first pointer 12a) as a center, the display is enlarged to have a size that is, for example, 1.2 times the normal display (see FIG. 4).

  As described above, the present embodiment includes the image display device 10 that can display the speedometer image 12 and the tachometer image 13 as images to the user, and the control unit 30 that controls the operation of the image display device 10.
