Abstract

A portable electronic device has a display part (16) which can display a plurality of selection items; an operation part (12) for selecting the selection item displayed on the display part (16); and a control part (18) which switches the selection item to other selection item selected from the selection items displayed on the display part (16) by operation of the operating part (12). The control part (18) has a function of changing the switching speed of the selection item selected by the operation of the operation part (12) in accordance with display mode of each of the selection items displayed on the display part (16). Thus, usability is improved by, for instance, changing a scroll speed for the continuous selection operation.

Claims

1. A portable electronic device, comprising

a display part capable of displaying a plurality of selection items,

an operation part for selecting a selection item displayed on the display part, and

a control part switching the selection item selected along with operation of the operation part from the plurality of selection items which being displayed on the display part, wherein

the control part changes a switching speed of the selection item selected along with operation of the operation part in accordance with a display form of the plurality of selection items displayed on the display part.

2. A portable electronic device as set forth in claim 1, wherein the control part changes the switching speed of the selection item selected along with operation of the operation part in accordance with a number of the plurality of selection items displayed on the display part.

3. A portable electronic device as set forth in claim 2, wherein the control part capable of selectively executing a first display processing of displaying the plurality of selection items on the display part by a predetermined display form and a second display processing in which the number of selection items displayed on the display part is smaller than the number of selection items in the first display processing and sets the switching speed in the second display processing slower than the switching speed in the first display processing.

4. A portable electronic device as set forth in claim 3, wherein when the second display processing is executed, the control part displays, on the display part, specific selection items among the plurality of selection items displayed at the time of execution of the first display processing.

5. A portable electronic device as set forth in claim 3, wherein the control part displays the selection items displayed on the display part when the second display processing is executed enlarged from the selection items displayed on the display part when the first display processing is executed.

6. A portable electronic device as set forth in claim 1, wherein the control part changes the switching speed of the selection item selected along with operation of the operation part in accordance with a display size of the selection items being displayed on the display part.

7. A portable electronic device as set forth in claim 6, wherein the control part sets the switching speed of the selected selection item slower than the switching speed of the other selection items when the display size of the selected selection item is larger than the display size of the other selection items.

8. A portable electronic device as set forth in claim 1, wherein the control part changes the switching speed of the selection item selected along with the operation of the operation part in accordance with a amount of display information of the plurality of selection items being displayed on the display part.

9. A portable electronic device as set forth in claim 8, wherein the control part sets the switching speed of the selected selection item slower than the switching speed of the other selection items when the amount of display information of the selected selection item is larger than the amount of display information of the other selection items.

10. A portable electronic device as set forth in claim 1, wherein when the information displayed by a selection item is scrolled, the control part sets the switching speed of the selection item for which the display information is scrolled slower than the switching speed for a selection item which is not scrolled.

11. A portable electronic device as set forth in claim 1, wherein the control part changes the switching speed for the selection item when an operation for selecting the selection item is continuously carried out.

12. A portable electronic device as set forth in claim 11, wherein when the screen is switched from a first screen on which a portion of the plurality of selection items is displayed in accordance with the continuous operation for selecting a selection item to a second screen on which the remaining portion of the plurality of selection items is displayed, the control part changes the switching speed for the selection items displayed on the first screen in accordance with the switching time from the first screen to the second screen.

13. A portable electronic device as set forth in claim 1, wherein the plurality of selection items displayed on the display part include menu items of a function menu.

14. A portable electronic device as set forth in claim 1, wherein the plurality of selection items displayed on the display part include candidates for change of an input character at the time of character input processing.

15. A portable electronic device as set forth in claim 1, wherein the control part displays the selection item selected along with operation of the operation part by a display form different from the other selection items being displayed on the display part.
