Abstract

In a touch panel apparatus of the present invention, a plurality of operation buttons on an operation screen are divided into a plurality of groups. One or more operation buttons belonging to one of the groups are shown in a first size, and one or more operation buttons belonging to the other groups are shown in a second size that is smaller than the first size. On the operation screen, a button size modification area is shown for each group in which the one or more operation buttons belonging to the group are shown in the second size. When one of the button size modification areas is selected, the operation screen is modified such that the one or more operation buttons belonging to the group corresponding to the selected button size modification area will be shown in the first size, and the one or more operation buttons shown in the first size will be shown in the second size.

Claims

1. A touch panel apparatus for displaying an operation screen that includes a plurality of operation buttons, and specifying a selected operation button using a touch panel, wherein

the plurality of operation buttons are divided into a plurality of groups,

on the operation screen, one or more operation buttons belonging to one of the groups are shown in a first size, one or more operation buttons belonging to the other groups are shown in a second size that is smaller than the first size, and a button size modification area is shown for each group in which the one or more operation buttons belonging to the group are shown in the second size, and

when one of the button size modification areas is selected, the operation screen is displayed after being modified such that the one or more operation buttons belonging to the group corresponding to the selected button size modification area will be shown in the first size, and the one or more operation buttons shown in the first size will be shown in the second size.

2. The touch panel apparatus according to claim 1, wherein an arrangement of the plurality of operation buttons is the same irrespective of size.

3. The touch panel apparatus according to claim 1, wherein when any of the plurality of operation buttons is selected, an operation corresponding to the selected operation button is performed irrespective of the size of the selected operation button.

4. A touch panel apparatus comprising:

a draw unit that creates image data for an operation screen that includes a plurality of operation buttons;

a display unit that displays the operation screen using the image data; and

a control unit that specifies a selected operation button using a touch panel, and executes an operation corresponding to the selected operation button, wherein

the plurality of operation buttons are divided into a plurality of groups,

on the operation screen, one or more operation buttons belonging to one of the groups are shown in a first size, one or more operation buttons belonging to the other groups are shown in a second size that is smaller than the first size, and a button size modification area is shown for each group in which the one or more operation buttons belonging to the group are shown in the second size, and

when one of the button size modification areas is selected, the control unit instructs the draw unit to modify the image data, and the draw unit modifies the image data such that the one or more operation buttons belonging to the group corresponding to the selected button size modification area will be shown in the first size, and the one or more operation buttons shown in the first size will be shown in the second size.

5. The touch panel apparatus according to claim 4, wherein an arrangement of the plurality of operation buttons is the same irrespective of size.

6. The touch panel apparatus according to claim 4, wherein when any of the plurality of operation buttons is selected, an operation corresponding to the selected operation button is performed irrespective of the size of the selected operation button.

7. A touch panel apparatus for displaying an operation screen that includes a plurality of operation buttons, and specifying a selected operation button using a touch panel, wherein

the plurality of operation buttons are divided into a plurality of groups,

one or more hardware keys are included for designating one of the plurality of groups,

on the operation screen, one or more operation buttons belonging to one of the groups are shown in a first size, and one or more operation buttons belonging to the other groups are shown in a second size that is smaller than the first size, and

when one of the one or more hardware keys is pressed and one of the groups in which the one or more operation buttons are shown in the second size is designated, the operation screen is displayed after being modified such that the one or more operation buttons belonging to the designated group will be shown in the first size, and the one or more operation buttons shown in the first size will be shown in the second size.

8. The touch panel apparatus according to claim 7, wherein an arrangement of the plurality of operation buttons is the same irrespective of size.

9. The touch panel apparatus according to claim 7, wherein when any of the plurality of operation buttons is selected, an operation corresponding to the selected operation button is performed irrespective of the size of the selected operation button.

10. An operation button display method of an electronic device for displaying an operation screen that includes a plurality of operation buttons, and specifying a selected operation button using a touch panel, comprising:

a step of displaying an operation screen on which the plurality of operation buttons are divided into a plurality of groups, one or more operation buttons belonging to one of the groups are shown in a first size, one or more operation buttons belonging to the other groups are shown in a second size that is smaller than the first size, and a button size modification area is shown for each group in which the one or more operation buttons belonging to the group are shown in the second size; and

a step of modifying the operation screen, when one of the button size modification areas is selected, such that the one or more operation buttons belonging to the group corresponding to the selected button size modification area will be shown in the first size, and the one or more operation buttons shown in the first size will be shown in the second size.

11. The method according to claim 10, wherein an arrangement of the plurality of operation buttons is the same irrespective of size.

12. The method according to claim 10, further comprising a step in which, when any of the plurality of operation buttons is selected, the electronic device performs an operation corresponding to the selected operation button irrespective of the size of the selected operation button.
