  FIG. 2B shows an operation flow of the display control unit 22 of the center server 2, and the display control unit 22 checks whether or not the content request information from the client terminal 3 is received by the server communication unit 20. In step S10, the check in step S10 is repeated as an event reception (occurrence) standby operation.

  When the event reception content request information is received, the display control unit 22 extracts the display information of the client terminal 3 from the content request information received from the server communication unit 20 (step S11). Size information corresponding to the physical size and resolution of the display 30 described in the extracted display information is derived from the information table 20a of the storage unit 20 (step S12), and button icon display is performed based on the derived size information. The screen content data described in HTML including the button icon of this display size is created (step S13), the created screen content data is passed to the server communication unit 20 (step S14), and step S10 Return to. The server communication unit 20 performs processing for transmitting the screen content data received from the display control unit 22 to the corresponding client terminal 3.

  The client terminal 3 displays screen content on the display 30 through steps S2 and S5 in FIG. 2A. At this time, the display size of the button icon displayed corresponding to the touch panel 30a is used. The display device 30 is displayed in a size suitable for the pressing operation regardless of the physical size and resolution of the display device 30, and the operability when the button icon is pressed with a finger is ensured.

  In the above-mentioned system, the display device information transmitted from the client terminal 3 to the center server 2 is the physical size and resolution of the used display device 30, but in the case of the display device 30 having a known physical size and resolution, the physical information is displayed. A replacement code corresponding to the combination of size and resolution is set, this code is sent to the center server 2 as display device information, and the center server 2 determines the physical size and resolution of the display device from this code. Also good. In this way, if the display information is transmitted with the code, the information amount of the display information transmitted from the client terminal 3 can be reduced.

In the case described above, the display size of the button icon is different between the physical size of the display 30 of 5 inches and 7 inches, but the display size of 5 inches is reduced by setting the same display size. Even with the device 30, the same operability as 7 inches can be secured by making the size of the button icon the same as that of the display device 30 of 7 inches. That is, the same operational feeling can be obtained even if the physical size of the display 30 is different. For example, when the display size of the physical size is 5 inches and the resolution is QVGA is “1”, the display 30 having the same physical size and the resolution of VGA doubles the number of vertical and horizontal pixels as shown in Table 1. Even if the resolution is different, the display size is the same. However, when the physical size is 7 inches, when the display data having the same number of pixels of the button icon is used, the display size is 1 corresponding to the increase in the physical size. Although it is a little larger than 4 times, in order to make it the same size as the display size on the 5-inch display 30, the number of vertical and horizontal pixels of the button icon displayed on the 5-inch display 30 is set to 1 unit. In this case, the unit of the number of pixels in the vertical and horizontal directions of the button icon displayed on the 7-inch display 30 may be 5/7 times that of 5 inches (both QVGA and VGA).
(Embodiment 2)
In the information table 20a of Table 1 used in the above-described first embodiment, the physical size is only 5 inches and 7 inches, so that the physical size is provided with the other display devices 30. Although not compatible with the client terminal 3, the present embodiment is characterized in that the display size of the button icon is not derived by referring to the table, but by automatic calculation.

  That is, when the physical size of the display 30 indicated by the display information transmitted from the client terminal 3 is a new client terminal that is not 5 inches or 7 inches, the display control unit 22 obtains the display size by the following expression. .

Number of vertical and horizontal pixels of the button icon displayed on the display 30 of the new client terminal = α × K × [(physical size of the reference display 30 / physical size of the display 30 of the new client terminal)]
Here, α is a unit of the number of pixels in the vertical and horizontal directions of the button icon of the reference size displayed on the reference display 30, K is a coefficient corresponding to the resolution of the reference display 30, and in the case of QVGA, “1”. “In the case of VGA, it is“ 2 ”, which is selected according to the resolution of the display 30 of the new client terminal.

  For example, when the physical size of the display 30 of the new client terminal is 3.5 inches and the resolution is QVGA, the physical size of the reference display 30 is 5 inches and the resolution is QVGA. In order to display a button icon having the same display size as the reference at 30, α × 1 × (5 / 3.5) = about 1.43α. When the resolution of the display 30 of the new client terminal is VGA, the button icon display data in which the vertical and horizontal pixel units are α × 2 × (5 / 3.5) = about 2.86α. Should be created.
