  Here, with reference to FIG. 4 and FIG. 5, the above function will be described in more detail. FIG. 4 is an explanatory diagram showing a display example of the display screen 30 when the user ID input field 40a is selected by the user as described above. FIG. 5 is an explanatory diagram showing a display example of the display screen 30 when the password input field 40b is selected by the user. As shown in FIG. 4, when the type of the field 40 selected by the user is not a control field, the display control unit 106 relates to a plurality of character input keys 500 with respect to the initially set character color (hereinafter referred to as “character”). Characters are displayed with an initial character color), and areas other than the characters are displayed with an initial character background color (hereinafter referred to as an initial background color). Here, the initial character color is an example of the second color in the present invention. In principle, the initial background color is set as a color that is not related to the initial character color. This is because the visibility of the software keyboard 50 is increased at the time of initial setting.

  As shown in FIG. 5, when the type of the field 40 selected by the user is a control field, the display control unit 106 sets the initial character color (for the plurality of character input keys 500 ( Hereinafter, a character is displayed in a color different from the initial character color (hereinafter referred to as a changed character color), and an area other than the character is displayed in a similar color of the changed character color. As an example, if the initial character color is black and the initial background color is white, the change character color is set to blue (which is a color different from black), and the change character color is set to a dark blue color (which is a similar color of blue) Can be done. The changed character color is an example of the first color in the present invention. Further, these initial character colors and changed character colors may be changed by the user.

  As a modification, when the type of the field 40 selected by the user is a control field, the display control unit 106 displays characters in the initial character color with respect to the plurality of character input keys 500, and the characters Other areas may be displayed in the same color as the initial character color. Alternatively, the display control unit 106 may display an area other than the character with the initial background color and display the character with a similar color of the initial background color with respect to the plurality of character input keys 500.

  According to this display example, when the control field is selected by the user, the characters included in the software keyboard 50 and the background of the characters are displayed in similar colors, so the visibility of the software keyboard 50 is greatly reduced. . For this reason, for example, when the user inputs a password, even if the display screen is stolen by another person, it is difficult for others to recognize the characters input by the user on the software keyboard 50. It can be hard to be stolen.

-Display control example 2 (B)-
Further, the display control unit 106 can change the display color of the entire display screen based on the determination result by the determination unit 104. More specifically, the display control unit 106 determines the relationship between the display color of characters in a plurality of character input keys (included in the software keyboard) and the display color of the display screen based on the determination result by the determination unit 104. It is possible to change.

  Here, the above function will be described in more detail with reference to FIG. FIG. 6 is an explanatory diagram showing another display example of the display screen 30 when the password input field 40b is selected by the user. As shown in FIG. 6, when the type of the field 40 selected by the user is a control field, the display control unit 106 displays the characters included in the plurality of character input keys 500 in the changed character color, In addition, the display screen 30 is displayed in a similar color of the changed character color.

-Display control example 2 (C)-
Further, the display control unit 106 can change the brightness of the display screen based on the determination result by the determination unit 104. For example, when the type of the field 40 selected by the user is a control field, the display control unit 106 sets the luminance of the display screen to a value equal to or lower than a predetermined threshold. If the type of the field 40 selected by the user is not a control field, the display control unit 106 sets the brightness of the display screen to an initial value.

  According to this display example, when the control field is selected by the user, the visibility of the entire display screen is greatly reduced. For this reason, for example, when the user inputs a password, even if the display screen is stolen by another person, it is difficult for others to recognize the characters input by the user on the software keyboard. Can be made rare.

-Display control example 2 (D)-
Further, the display control unit 106 can change the size of characters displayed on a plurality of character input keys included in the software keyboard based on the determination result by the determination unit 104.

  Here, the above function will be described in more detail with reference to FIG. FIG. 7 is an explanatory diagram showing another display example of the display screen 30 when the password input field 40b is selected by the user. As shown in FIG. 7, when the type of the field 40 selected by the user is a control field, the display control unit 106 sets the size of characters included in the plurality of character input keys 500 (for example, in FIG. 4). Display smaller than the default size (as shown).

  According to this display example, when the control field is selected by the user, the characters are displayed in a reduced size on the software keyboard 50, so that the visibility of the characters on the software keyboard 50 is greatly reduced. For this reason, for example, when the user inputs a password, even if the display screen is stolen by another person, it is difficult for others to recognize the characters input by the user on the software keyboard 50. It can be hard to be stolen.

  FIG. 8 is a flowchart showing the operation of the mobile terminal 10 according to the present embodiment. As shown in FIG. 8, first, the display control unit 106 of the mobile terminal 10 displays the WEB page including a plurality of fields received from the WEB server 20 and the software keyboard generated by the display control unit 106 on the display screen. It is displayed (S101).

  Subsequently, the control unit 100 monitors whether or not any of the fields is focused, for example, when the operation recognizing unit 102 recognizes an operation of selecting any of the plurality of fields (S102). When no field is focused (S102: No), the control unit 100 repeats the operation of S102.

  On the other hand, when any of the fields is focused (S102: Yes), the determination unit 104 determines whether the type of the corresponding field is a control field (S103).

  When it is determined that the type of the corresponding field is a control field (S103: Yes), the display control unit 106 displays the character display color and the character background color in a plurality of character input keys included in the software keyboard. Are respectively changed from the initial character color and the initial background color (S104).

  When the character color and the character background color have not been changed (S104: No), the display control unit 106 changes the character display color from the initial character color for a plurality of character input keys included in the software keyboard. The character color is changed, and the display color of the area other than the character is changed from the initial background color to a similar color of the changed character color (S105).

  On the other hand, if it is determined in S103 that the type of the corresponding field is not a control field (S103: No), the display control unit 106 uses a plurality of character input keys included in the software keyboard, as in S104. It is checked whether the display color of the character and the background color of the character have been changed (S106).

  If the character color and the character background color have been changed (S106: Yes), the display control unit 106 changes the character display color from the changed character color to the initial value for a plurality of character input keys included in the software keyboard. The character color is returned, and the display color of the area other than the character is returned from the similar color of the changed character color to the initial background color (S107).

  Thereafter, the mobile terminal 10 displays the WEB page received from the WEB server 20 and the software keyboard on the display screen (S202).

  Thereafter, the mobile terminal 10 monitors whether or not any of the fields is focused, for example, when an operation of a user who selects any of the plurality of fields is recognized (S203). When any field is focused (S203: Yes), the mobile terminal 10 transmits the type of the corresponding field to the WEB server 20 (S204).

  Thereafter, the WEB server 20 determines whether or not the type of the corresponding field received from the mobile terminal 10 is a control field (S205).

  When it is determined that the type of the corresponding field is a control field (S205: Yes), the WEB server 20 displays the character display color and the character background color for a plurality of character input keys included in the software keyboard. Are respectively changed from the initial character color and the initial background color (S206).

  When the character display color and the character background color are not changed (S206: No), the WEB server 20 changes the character display color from the initial character color with respect to a plurality of character input keys included in the software keyboard. The color is changed to the changed character color, and the display color of the area other than the character is changed from the initial background color to a similar color of the changed character color (S207).

  Subsequently, the WEB server 20 transmits the software keyboard changed in S207 to the mobile terminal 10 (S208).

  Thereafter, the mobile terminal 10 replaces the software keyboard displayed on the display screen with the software keyboard received in S208, and updates the display on the display screen (S209).

  On the other hand, when it is determined in S205 that the type of the corresponding field is not a control field (S205: No), the WEB server 20 determines the character of the plurality of character input keys included in the software keyboard as in S206. It is confirmed whether the display color and the background color of the character have been changed (S211).

  Next, operations after S211 will be described with reference to FIG. As shown in FIG. 10, when the character display color and the character background color have been changed (S211: Yes), the WEB server 20 uses a plurality of character input keys included in the software keyboard. Is changed from the changed character color to the initial character color, and the display color of the area other than the character is returned from the similar color of the changed character color to the initial background color (S212).

  The operations after S212 are the same as the operations in S208 to S209.

For this reason, similarly to this embodiment, the visibility of the display screen can be variably changed according to the field selected by the user from the plurality of displayed fields.

  Further, according to the first modification, the WEB server 20 performs all display control in principle, so that the mobile terminal 10 can realize the same function as that of the present embodiment only by including, for example, a WEB browser. For this reason, the mobile terminal 10 can be configured inexpensively and simply.

<3-2. Modification 2>
The information processing apparatus according to the present invention may be an ATM (Automated Teller Machine) equipped with a touch panel display.

<3-3. Modification 3>
In the above description, an example in which the control field is a password input field has been described. However, the present invention is not limited to this example. The control field may be an input field for personal information such as a name and address (hereinafter referred to as a personal information field). In the third modification, it is necessary to set the personal information field so that characters input from the software keyboard are displayed in an invisible (or difficult to view) manner in the personal information field. Therefore, for example, the mobile terminal 10 uniformly displays characters input by the user with a symbol such as “*” in the personal information field, or sets the display color of the personal information field to, for example, black. In addition, if the input data itself is not visible, such as when the input character string in the target input field is displayed in place of “*” or the like, the visibility display mode may be changed. It may be a partial area including at least the software keyboard instead of the entire screen.

<3-4. Modification 4>
The type of the control field may be set by the user. For example, when the control field setting mode is selected by the user, the mobile terminal 10 can set a field selected by the user from among a plurality of fields displayed on the display screen as the control field. is there.

  The storage unit 126 can also store the type of a field that has been selected in advance as a control field by the user. Then, the determination unit 104 can determine whether or not the type of the field selected by the user on the display screen is a control field by referring to the storage contents of the storage unit 126.

<3-5. Modification 5>
In addition, according to each embodiment of the present invention, it is also possible to provide a computer program for causing hardware such as the CPU 150, the ROM 152, and the RAM 154 to perform the same functions as the components of the mobile terminal 10 described above.
